Concrete cutting in Al Khobar means opening or modifying a concrete wall, slab or floor in an apartment, villa, shop or office with diamond saws and core bits that cut in straight, clean lines instead of hammering the structure apart. What makes Khobar different is that most jobs happen inside buildings people are already using: an apartment block with neighbours above and below, a shop on a busy commercial street that wants a wider front, or an office being refitted between working days. Aemar Al-Maryam General Contracting carries out this work from its base in Dammam. A small opening costs from SAR 90, cutting runs from SAR 75 a linear metre, and a door or window opening costs SAR 140 upward; the figure is confirmed once we have seen the site. Call or WhatsApp 0547879578.
When people in Khobar contact us, the first question is rarely “how much?”. It is usually “will this disturb the neighbours?”, “will the building management allow it?” or “will water leak into the flat below?”. So we have written this guide from the point of view of someone who lives or works in an occupied building: how a wall is cut or a slab is cored in a space that is in use, what to arrange with building management before the day, which machine suits which job, and roughly what it costs.
Quick summary: concrete cutting in Al Khobar
- What we do: shopfront and entrance openings, AC and drain cores in apartments, doors between rooms, slab openings for a home lift or internal stair, and cable trenches in office floors.

Concrete cutting in Al Khobar: how the job changes between apartments, villas, shops and offices
Al Khobar is a dense mix of apartment blocks, villas, shops and office buildings, and each type calls for a different way of planning and cutting. The same wall might be reinforced concrete in an apartment block, blockwork in a villa and a load-bearing front in a shop. That is why every Khobar enquiry starts with a simple question: what kind of building will the opening be in, and who else shares that building?
■ Apartments in residential blocks
Most requests are cores for an AC unit or a drain pipe, or a door between two rooms. The challenge here is neighbours, water and noise rather than the size of the opening.
■ Villas
A door onto the yard, linking a room with the majlis, slab openings for a home lift or stair, and small openings in the roof parapet for rainwater outlets.
■ Shops
Opening or widening a shopfront, a rear loading door, and extract and flue openings for restaurants and bakeries, all next to a pavement with pedestrians and traffic.
■ Offices and showrooms
Floor cutting for cable routes, doors between offices and coring for AC ducts when space is re-planned.
This variety means the equipment we take to Khobar is chosen for each job rather than loaded the same way every time. An apartment on a high floor needs a compact core rig that fits in the lift. A shop on the street needs a wall saw and pavement barriers. An office needs a floor saw and a powerful wet vacuum. You can find the full service description on our concrete cutting and coring service page.
Photograph the wall and send it to us
One clear photo with the size and floor number lets us suggest a method and give you a cost estimate for your Khobar address.
A concrete cutting company in Al Khobar working inside an occupied building
A concrete cutting company in Al Khobar that works inside occupied buildings has to think about the neighbours before it thinks about the wall. Diamond saws and core rigs are far quieter than a pneumatic breaker, but they still make noise and vibration that can be heard on nearby floors, and they use cooling water that can find its way through cracks or service openings into the flat below if it is not controlled. So we arrange these things before we arrive:
- 1Tell the building management or owner
We ask you to coordinate with the management or the building watchman, and we give you a short written description of the work: the type of opening, its location, the expected duration and the equipment that will come in. - 2Choose working hours
We suggest times that cause the least disturbance and avoid usual rest hours. If the building has its own rules on working hours, we follow them. - 3Protect corridors and the lift
We cover the corridor floor and the lift walls when bringing equipment in, and we move it at times when residents are not queuing for the lift. - 4Control the water
We use a measured amount of water with a wet vacuum that removes water and slurry as soon as it appears, and we place sponge dams around coring points in slabs. - 5Check the flat below
When coring through a slab we ask for access to the flat underneath where possible, so we can protect what is below and catch the cut core rather than let it drop.
A tip before the day
Ask the building management whether there is a temporary parking space for the equipment vehicle or a service entrance. In many Khobar blocks, bringing equipment in from the basement car park is easier and less disruptive than using the main entrance.
Sometimes an owner asks for all noisy work to happen on one particular day of the week, or for every opening needed in the building to be done in a single visit. That works in your favour too: grouping several openings into one day lowers the cost of each opening and reduces the number of times neighbours are disturbed.
Wall cutting in Al Khobar without breaking: why it suits closely built buildings
Wall cutting in Al Khobar without breaking means a diamond saw first runs around the outline of the opening until the block is free from the wall, and only then is it taken out in pieces. The rest of the wall and the walls next to it are never hammered. In a city where buildings stand close together and apartments are stacked on top of each other, this is not a luxury. Hammering a shared wall with a breaker sends vibration into the neighbour’s flat, can crack their tiles or plaster, and turns you from a client into a party to a dispute.
The difference also shows in the finishing. A sawn edge is straight and almost smooth, so a door frame or aluminium frame can be fixed to it with very little plastering. A broken-out opening needs its edges rebuilt, cracks around it repaired and a much larger area repainted. Once you count the repair cost, cutting is the cheaper choice in most cases.
■ Less vibration
No hammering on the existing wall, so neighbours’ walls and tiles are kept away from the work.
■ Dust under control
Wet cutting stops fine silica dust from spreading into corridors and the stairwell.
■ Ready edges
Straight lines that cut down the plastering and painting needed afterwards.
■ Shorter disruption
Organised work finishes faster than stop-start breaking that can drag on for days.
Door and window openings in a concrete wall in Al Khobar: shopfronts and entrances
Cutting a door or window into a concrete wall in Al Khobar starts with marking the opening; a diamond wall saw then runs along all four sides until the block is free, and the block comes out in pieces, and the surrounding wall never takes a hammer blow. In Khobar we see a lot of shop requests: an owner who wants a wider glass front, a restaurant that needs a side door for deliveries, or a small store room behind a shop that needs a loading door.
A shopfront is a special case because it is usually part of the building’s external wall and may carry a beam or the first-floor slab. So we never cut a shopfront without knowing what sits above it. Before pricing, we ask for a photo of the front from outside, a photo of the same wall from inside, the shop plan if there is one, and whether there are apartments or offices above the shop.
Steps for opening a shopfront on a commercial street
- 1Engineering advice and permit
Widening a shopfront changes the building’s appearance and may affect a load-bearing element, so it is reviewed with an engineering office and the necessary permit is obtained through the Balady platform where required. - 2Secure the pavement
Barriers and warning tape, covers over neighbouring shop windows, and pedestrians guided away from the cutting zone. - 3Temporary support
Props, plus a support beam over the opening where the engineer’s design requires one, all in place before the first cut. - 4Cutting on a track
A wall saw fixed to a track cuts the sides, top and bottom in straight lines ready for the frame. - 5Lifting and loading
The block is divided into liftable pieces and loaded straight onto the debris vehicle so nothing is left on the pavement.
⚠ Note for shops beneath apartment blocks
If the shop is under residential flats, the front wall is most likely part of the building’s structure. It is not cut before an engineering office approves it, and we never cut a column under any circumstances.
A door between two rooms or two offices
Inside apartments and offices, the request is usually a door linking two rooms or a passage between two offices after the space has been re-planned. If the wall is non-load-bearing blockwork, the job is simpler and can be done with a smaller saw. If it is reinforced concrete, we use the wall saw after confirming it is not load-bearing. Our page on door and window openings covers this in more depth.
Concrete coring in Al Khobar apartments: AC, drains and extract fans
Concrete coring in Al Khobar is what apartment residents ask for most: a clean round hole in a wall or slab for an AC pipe, a drain or a kitchen extract fan, with a complete concrete cylinder coming out and nothing broken around it. The rig is anchored to the wall on a stand, the diamond bit turns with cooling water, and the wet vacuum picks up the water as it comes out.
In apartments we care about two things: that the hole is in the right place for the pipe route, and that it does not hit main reinforcement or a hidden service. So we fix the position with the AC technician or plumber and scan the wall with a rebar detector before drilling. A split AC hole, for example, is around 65 mm, drilled with a slight slope towards the outside so condensate drains outside instead of running back indoors, which is what AC makers’ installation guides call for.
| Common Khobar request | Approximate diameter | What we watch for |
|---|---|---|
| Split AC in an apartment | About 65 mm | Outward slope, and staying clear of beams and columns |
| Drain pipe from a bathroom or kitchen | Matched to the pipe’s outside diameter (often 4 to 5 inches) | Where the pipe lands in the flat below before coring the slab |
| Kitchen or bathroom extract fan | About 6 inches | An exhaust route that does not face a neighbour’s window |
| AC duct in an office | 8 inches and larger | Rebar scan; large diameters may need an engineer’s opinion |
| Electrical and data lines | Under 100 mm | Locating existing cable routes before drilling |
Note: Diameters are a guide. Always size the hole to the pipe or duct running through it.
Concrete core drilling in Al Khobar for restaurants and bakeries: extracts and flues
Concrete core drilling in Al Khobar for restaurants is different from apartments in size and location. An oven flue or a commercial kitchen extract needs a bigger hole, usually in the slab or in the rear wall facing a service lane. Sometimes the opening is round and large, so it is drilled with a large core bit. Sometimes it is square for an extract duct, so we start with cores at the corners and then saw between them. Because the restaurant is usually trading, we schedule the work when it is closed or before it opens.
If coring is all you need, our core drilling page lists every diameter and typical use.
Concrete cutting and coring in Al Khobar office and showroom refits
Concrete cutting and coring in Al Khobar is a core part of office refits. Re-planning a floor usually means moving power and data points, running a new duct and opening a door between two departments. Most of this work involves cutting the floor rather than the wall: straight lines in the ground slab with a floor saw to bury cable conduits, then closing the trench again before tiling.
■ Floor cutting for cables
Straight cuts to a set depth in the ground slab to carry power and data conduits to new workstations.
■ AC duct openings
Coring or sawing openings in internal walls and slabs for duct routes, checked against the HVAC drawings.
■ Doors between departments
Cutting an internal wall for a door or passage, with an opening ready for the frame straight after cutting.
■ Server and electrical rooms
Precise cores for cable and cooling routes, with every existing service checked first.
In working offices we propose doing the work at the weekend or after hours, we isolate the work area with plastic sheeting, and we use wet extraction so that dust does not reach equipment. If the building has facilities management or security, we deal with them directly and provide whatever paperwork they need for our team and equipment to enter.
Cutting a wall with a grinder in Al Khobar: small openings on roofs and parapets
Cutting a wall with a grinder (the hand-held cut-off saw people call “al-sarookh”) in Al Khobar is fine for small openings and shallow cuts, such as a rainwater outlet in a roof parapet or a socket box in a block wall. It is not enough to cut through a whole reinforced concrete wall, because even the largest 14-inch hand-held cutters reach only about 125 mm deep.
On villa roofs in Khobar we often get asked to improve rainwater drainage after a room has been added or the roof falls have changed. A small opening in the parapet is enough here, and a hand-held cutter with water does the job well. What matters is protecting the roof waterproofing from water, slurry and cutting debris, and fitting the outlet straight afterwards.
- ✓A grinder is fine for: a small outlet or vent in a parapet, socket boxes in block walls, and trimming the edges of an opening already cut with a saw.
- ✓It is not enough on its own for: a reinforced wall thicker than the blade depth, a door opening that needs straight edges on both faces, or any slab cutting.
- ✓Cost: small openings start from SAR 90; longer cuts go by the linear metre or are priced on inspection.
Concrete saw in Al Khobar: which machine comes to your site?
A concrete saw in Al Khobar is chosen according to where the cut is, how thick the element is and how easy the access is, not according to what happens to be in the van. In apartment blocks we also think about size and weight: will the machine fit in the lift, and can the corridor take it?
| Situation in Khobar | Suitable machine | Why |
|---|---|---|
| Shopfront or door in a reinforced wall | Track-mounted wall saw | Heavy-class units reach roughly 730 mm from a single face, in a dead-straight line |
| Cable route in an office floor | Floor saw | Roughly 24 cm of depth along long, true lines |
| AC or drain hole in an apartment | Core drill | Typical rigs drill clean holes of 12–500 mm |
| Very thick base or element | Diamond wire saw | Not limited by blade diameter, with low vibration |
| Small opening in a parapet or block wall | Hand-held cut-off saw | Up to about 125 mm deep, for light work |
Note: Figures describe typical machines in each class; what is achievable on your job depends on the exact saw and how heavily the concrete is reinforced.
Before cutting, we use a rebar detector and a laser level to set out the lines, fix the saws with anchors and tracks, and prepare steel props and hoists so cut blocks are lowered safely.
“Laser” wall cutting in Al Khobar: the reality behind the term
“Laser” wall cutting in Al Khobar is a common search, but what actually cuts reinforced concrete is a diamond saw. The laser is a measuring tool used to mark the lines of the opening, check they are straight and set their level before cutting. No machine on the contracting market will slice through a 20 cm reinforced wall with a laser beam; using lasers on concrete has stayed within research trials that strip the surface to a limited depth.
The result people expect when they type “laser” is a clean, straight edge with no breaking, and that is exactly what a track-mounted wall saw delivers once the lines have been set out by laser. Our Dammam laser-cutting article goes into more depth, and everything there holds true in Khobar.
Slab cutting in Al Khobar: a home lift or internal stair opening
Slab cutting in Al Khobar is usually requested in villas where the owners want to add a home lift for elderly family members, an internal stair linking two floors after the villa has been divided, or a light well. It is precise structural work: the slab carries itself and whatever sits on it, and the cut piece is heavy and overhead.
- 1An engineering drawing for the opening
The engineering office sets the size and location of the opening and the strengthening needed around it, and we follow it exactly. - 2Props before any cut
Adjustable steel props under and around the section being removed on the floor below. - 3Divide the opening
The opening is broken down into sections light enough to lift or lower safely; no large block is ever dropped. - 4Cut and lower
Either a floor saw working from above or a wall saw does the cutting, and a chain hoist brings each piece down. - 5Protect the finishes
Covering the marble and walls on both floors and removing water and slurry immediately.
Villa lifts come in sizes set by the supplier, so ask them for the clear opening size before we start. That way the slab is cut once, to the right size.
Reinforced concrete cutting in Al Khobar: rebar and post-tensioned slabs
Reinforced concrete cutting in Al Khobar is possible because diamond blades and bits go through concrete and rebar alike. Still, the important question is not “can we?” but “should this steel be cut?”. For a small core we avoid main bars by moving the hole slightly after scanning. For a door or slab opening, it is the engineer who says which bars may go and how the opening is strengthened.
Some modern commercial and office buildings use post-tensioned slabs with steel tendons under very high tension. Cutting a tendon can cause injuries and serious damage to the slab, so a ground-penetrating radar (GPR) scan is a condition before any hole is drilled in these slabs. If you are in a modern office or showroom and do not know what type of slab you have, tell us so we can check it before pricing.
⚠ What we do not do
Columns are off-limits for us. Beams are only cored where a structural engineer has put the location and diameter in writing, and main slab reinforcement is only cut against an approved drawing.
Debris removal and breaking out after the cut in Al Khobar
Cutting separates the block, but one practical question remains: where do the pieces go? In a Khobar apartment block, concrete pieces cannot be left in the corridor or stairwell, nor thrown into the neighbourhood skip. So before we start we agree with you what the price includes: do we cut the block into small pieces and bring them down to the ground floor only, or do we load them and take them to an approved disposal site?
Occasionally the job is more than a single opening: taking out an entire internal wall, say, or breaking up an old shop floor before fit-out. In that case diamond cuts mark the boundary first and the section inside is broken out in a controlled way, leaving everything around it intact. You can read more on our demolition and breaking service page.
Choosing a concrete cutting company in Al Khobar: five things to check first
When you receive several quotes for concrete cutting in Khobar, do not compare the numbers alone. Ask each company these questions; the answers will show you who understands working in occupied buildings:
- ✓Which machine will you use? A clear answer names a wall saw or core rig for the situation, not “we will sort it out on site”.
- ✓How will you deal with water and slurry? You should hear about wet vacuuming and protecting floors and drains.
- ✓Does the price include lifting out and removing the pieces? Agree this in writing in a WhatsApp message before work starts.
- ✓Does the opening need an engineer? A serious company tells you plainly when the work is a structural alteration.
- ✓Can I see previous work? Photos or videos from completed sites are enough to judge edge quality and cleanliness.
Do you need a permit or an engineer to cut concrete in Al Khobar?
In short: a small hole for an AC line or a pipe rarely touches the structure once scanning has cleared the spot. A new door or window in a wall that carries load, a wider shopfront or any opening through a slab is a different matter. That is structural work, which calls for an accredited engineering office’s report, and a Balady permit may be required as well. In apartment blocks there is a third party too: the owner, the owners’ association or the building management.
| Work | Who usually needs to agree | Notes |
|---|---|---|
| AC or plumbing core in an apartment | Building management (for coordination and notice) | Scan for rebar and services before coring |
| Door in an internal block wall | The owner | Confirm the wall carries nothing |
| Door in a load-bearing concrete wall | Engineering office; a permit may be needed | Props and a support beam as designed |
| Widening a shopfront | Engineering office and building owner; usually a permit | A change to the building’s appearance |
| Slab opening for a lift or stair | Engineering office; a permit may be needed | Strengthening around the opening as drawn |
On Balady, the relevant services are the Building Restoration Permit (bringing a building back to how it was, with its structural elements unchanged) and Adding and Modifying Building Components (adding, altering or deleting an element recorded on the current building permit). Each one needs an engineering office under contract; once the drawing is approved, we cut to it.
Safety when cutting concrete in buildings people walk through
In shared buildings, safety is not only about our team; it also covers residents, passers-by and customers. Wet cutting stops the spread of fine silica dust, which harms the lungs, and the water itself needs managing: watertight electrical connections, residual-current protection, and cutting the power to the work zone when necessary.
■ Isolate the work area
Barriers and warning tape in the corridor or on the pavement, and a simple sign to alert residents or customers.
■ Protect the team
Eye protection, gloves, ear defenders and steel-toe boots for every crew member.
■ Support the blocks
No piece is left to fall, and slabs are cut into small sections lowered by hoist.
■ Clean up afterwards
We leave the corridor and lift as we found them, with no slurry or concrete debris.
Concrete cutting prices in Al Khobar
Concrete cutting prices in Al Khobar at Aemar Al-Maryam are the same as in Dammam, because Khobar is part of our everyday working area. Entry prices are SAR 90 for a small opening and SAR 75 a linear metre for cutting, while a door or window starts at SAR 140. The full list:
| Service | Typical Khobar use | Price (SAR, from) |
|---|---|---|
| Small hole up to roughly 100 mm | Apartment split AC, power cable | 90 per hole |
| 125 mm core (5 in) | Bathroom drain | 140 |
| 150–160 mm core (6 in) | Kitchen extractor | 140 |
| 200 mm core (8 in) | Office AC duct | 230 |
| 250 mm core (10 in) or wider | Restaurant flue, large duct | Priced on inspection by diameter and thickness |
| Sawing by the metre, wall or floor | Office cable route | 75 per linear metre |
| Door or window | Door between two rooms | 140 |
| Full wall cut, by floor | Enlarging an existing opening | 280 |
| Shopfront, or slab opening for a stair or lift | Villa or shop | Priced on inspection and the engineering drawing |
Note: Treat these as estimates until we inspect and agree the job; thickness, rebar density, floor level and access move them up or down.
What pushes the price up or down in Khobar?
- ✓Floor level and lift: carrying equipment to a high floor without a lift takes more time and labour.
- ✓Permitted working hours: working set hours or at night in a shop or office can affect the cost.
- ✓Parking and loading: being able to park the equipment vehicle near the entrance shortens the job.
- ✓Debris removal: agree in advance on loading and taking away the pieces if you want this included.
- ✓Number of openings: the more openings in one visit, the less each one costs.
You can compare prices across all our services in the estimated price guide.
Common mistakes when cutting concrete in Khobar apartments and shops
- ✓Starting without telling the management: work stops halfway because of a neighbour’s or watchman’s complaint, and you pay for a second visit.
- ✓Coring a slab without knowing what is in the flat below: the bit may come out above a neighbour’s gypsum ceiling, chandelier or AC unit.
- ✓Using a grinder and hammer on a shopfront: broken edges, cracks and repair costs larger than the price difference.
- ✓Not matching the door or lift size: cutting an opening and then finding the frame or lift needs a different size.
- ✓Letting slurry into the drains: grey cutting slurry blocks bathroom and balcony drains if it is not vacuumed.
- ✓Ignoring the slab type in modern offices: drilling a post-tensioned slab without a GPR scan is a real hazard.

Al Khobar districts we serve and nearby cities
We reach residential and commercial districts across Al Khobar, including:
And the rest of the city’s districts; drop us a WhatsApp location pin and we will book a slot. You can find our services in the city on the Al Khobar contracting page. We also work in neighbouring cities: concrete cutting in Dhahran for villas and annexes, and concrete cutting in Dammam, where we are based, as well as Qatif, Saihat, Jubail and Al-Ahsa.
How we schedule Khobar visits from Dammam
We are based in Dammam and Khobar is part of our everyday working area, so ordinary jobs there carry no special travel charge. We group Khobar inspections into nearby time slots so we can reach you quickly, and if an opening is simple and clear from the photos, the inspection and the work can happen in the same visit provided the right kit is on the van. Structural work such as a shopfront or a slab opening needs a separate inspection first, and is scheduled for cutting once drawings and approvals are ready.
