Need a hole for a new AC unit, a doorway between two rooms, or a duct for the kitchen hood? Concrete cutting in Saihat with Aemar Al-Maryam General Contracting is done with diamond saws and core rigs that open a wall or slab along a straight, clean edge, without hammering and without dust drifting through the house. Saihat sits right next to our Dammam base, so inspections are arranged quickly, and we handle both small and large jobs in houses, flats and shops: AC, kitchen and bathroom cores, door and window openings, and slab cutting for stairs and skylights. A small opening costs from SAR 90, a metre of cut line from SAR 75 and a doorway from SAR 140, all subject to inspection and agreement. Phone and WhatsApp: 0547879578.
In a coastal town like Saihat, our job does not end when the cut block comes out. Humid sea air makes reinforcement exposed at the cut face more prone to rust over time, so we pay attention to treating the edges and closing the gap around pipes after coring. The aim is an opening that stays sound years later, not just for the first few weeks.

A Concrete Cutting Company in Saihat, a Short Drive From Our Base
Having a concrete cutting company in Saihat close at hand simply means the time between your first message and a technician at your door is short. Our base is in Dammam and the road to Saihat is short, so when a job is small and clear from the photos, such as an AC or extract-fan core, we can combine the inspection and the work in a single visit. When the job is bigger, say a doorway through a wall that carries the roof, or a hole in a floor slab, we come to inspect first and return with the right equipment.
That proximity shows in the price too. We add no separate distance charge for Saihat and price it from the same table as Dammam. Shop owners benefit most, because they need a fixed appointment before opening or after closing rather than an open-ended wait.
In practice we plan Saihat visits around the rest of the day’s work in Dammam and Qatif. A morning inspection in Saihat can turn into an afternoon cut if the photos were clear and the equipment is already on the vehicle, and a job that needs an engineer’s sign-off can be slotted in as soon as the drawing arrives, without starting the scheduling from scratch.
What changes in practice because we are close?
- ✓Faster inspections: Usually arranged soon after you contact us, depending on the teams’ schedule.
- ✓Same-visit work for simple jobs: If the photos and sizes are clear, we bring the equipment on the first trip.
- ✓Easy follow-up visits: When the job needs a second stage after the engineer approves, or after the plumber has fitted the pipe.
- ✓Dammam prices: No extra charge for normal travel within Saihat.
Small Jobs First: AC, Kitchen and Bathroom Openings in Saihat
What Saihat residents ask us for most is not demolishing a wall or opening a slab, but small, precise holes: a core for a new AC unit in a bedroom, a duct for the kitchen hood after new cabinets go in, a vent for a bathroom with no window, or a route for a new plumbing pipe. These jobs look simple, but mistakes are expensive: a hole in the wrong place, a core that clips a hidden pipe, or cutting slurry across a new kitchen floor.
AC core holes in Saihat
For a split AC unit we drill a hole of roughly 65 mm and run it on a gentle fall towards the street or courtyard, so condensate leaves the building instead of seeping into the wall, as AC installation guides recommend. The AC technician fixes the position with us beforehand: as near as possible to the indoor unit, with a safe margin from columns and beams. Once the pipes are through, we recommend sealing the gap around them on the outside with a waterproof sealant, which matters in Saihat’s humid air.
Kitchen hood and chimney flue openings
When a kitchen is renovated, the hob often moves and the extract fan moves with it. We core the concrete wall above the hob position with a bit of about 6 inches or larger to suit the duct, wrap the new cabinets in clear covers, set the extracted concrete core on a protected surface and vacuum the water as it runs. The result is a clean round hole ready to take the duct straight away.
Bathroom openings: ventilation, drainage and moved fittings
An internal bathroom without a window needs an extract fan that vents outside, and a bathroom renovation may move the toilet or basin and change the drain route. In both cases we core rather than break, so the tiles around the hole stay intact and the plumber can fit and seal the pipe easily. If the new drain needs a channel in the floor, we cut two parallel lines and remove only the strip between them.
Electrical, data and hidden service runs
Some small holes have nothing to do with AC or plumbing: a cable for a generator or an electric-car charger in the garage, a data line between two rooms, or a gas pipe for an outdoor kitchen. These holes are small in diameter, but they often pass close to existing services, so we run the detector over the wall before coring and confirm where live cables run so we do not hit one.
| Small job | Diameter or type | Price starts at |
|---|---|---|
| Split AC unit | Around 65 mm with an outward fall | SAR 90 |
| Plumbing or electrical run | Up to roughly 100 mm | SAR 90 |
| Drain or vent pipe | Around 5 inches | SAR 140 |
| Kitchen or bathroom fan | Around 6 inches | SAR 140 |
| Flue or small duct | Around 8 inches | SAR 230 |
| Channel in a bathroom floor | Line cuts, then removal | SAR 75 per metre |
Estimates until inspection and agreement: Thicker walls, higher storeys and fewer holes per trip push the figure up.
Bundle your openings into one appointment
If you are renovating, write down every opening you will need: AC units, extract fans, plumbing and electrics. Booking them together trims what each hole costs and keeps the water and slurry to a single day instead of several.
Coastal Humidity and Concrete in Saihat: Why We Treat Cut Edges
Reinforcing steel inside concrete is protected by the concrete that covers it. When we cut an opening, we sever bars and their ends appear on the cut face, now exposed to air and moisture. In coastal towns, where the air is humid and carries salt from the sea, rust starts on exposed steel sooner than it does in dry inland areas. Rust takes up more space than the original steel, so over time it pushes against the surrounding concrete and cracks it, and flakes or brown stains can appear around the opening.
That is why we do not consider an opening finished when the block comes out. After cutting, we take any visible rust off the bar ends and advise a rust-inhibiting primer on them, followed by a covering with repair mortar or a good render before the frame is fitted. For core holes that carry pipes to the outside, the gap around the pipe should be closed with a flexible sealant that keeps water out.
■ Cleaning the bar ends
Removing surface rust from the cut reinforcement on the face of the opening.
■ Anti-corrosion coating
A protective layer on the exposed steel before it is covered.
■ Repair mortar or render
Restoring the concrete cover over the steel and squaring the edge.
■ Sealing pipe surrounds
A flexible sealant that stops water and moisture entering around the pipe.
⚠ Do not leave the steel in an opening exposed
Some owners delay finishing an opening for weeks or months after cutting. In Saihat’s humid climate, steel left exposed for that long can begin to rust before it is ever covered. If finishing will be delayed, at least ask for the bar ends to be coated with an anti-corrosion primer straight after cutting.
How to tell if an older opening has started to rust
If you have an opening that was cut years ago and never had its edges treated, some signs suggest the steel is corroding: brown stains on the render around the opening, paint peeling in lines, a hairline crack running from a corner of the opening, or a small piece of render that has fallen away and revealed a dark bar. These signs do not always mean immediate danger, but they do mean treatment is overdue, and an early repair costs far less than waiting.
Treatment materials: what is used and when
The usual treatment has three stages: brushing the steel with a wire brush until clean metal shows, coating it with an anti-corrosion product made for reinforcement, then covering it with repair mortar or render thick enough to restore the concrete cover. Pipe surrounds in core holes are closed with a flexible sealant that tolerates the pipe’s movement and thermal expansion. We agree with the homeowner whether we carry out this treatment or leave it to the finishing contractor.
If cutting reveals that the steel inside the wall itself is corroded, not just at the edge, we stop, show you the photos and advise having an engineer look at it, as the element may need repair before the opening is completed.
Concrete Coring in Saihat for Ducts and Larger Core Holes
Concrete coring in Saihat is not limited to small holes. When a central or concealed AC system is installed, or a ventilation duct is run for a commercial kitchen, we may need bits of 8 or 10 inches and more. Here the rebar scan becomes more important, because a large bit may cut through several bars, and an engineer’s opinion may be needed if the hole is in a slab or close to a beam.
The core rig is fixed on a base anchored to the wall or slab, and common rigs cover diameters from about 12 mm to around half a metre. Large square duct openings begin with a core in each corner, after which the straight sides are sawn, so the corners come out clean without the blade running past them. For more on this service, see the core drilling service page.
Core drilling through slabs in Saihat
When coring a slab we scan first to place the hole between the bars, confirm no conduits run through it, and hold the cylinder from underneath so it cannot drop when it releases. If the slab is post-tensioned, a radar survey is required before any hole, because severing a tensioned tendon is dangerous to people and to the slab itself. Beams stay untouched unless a structural engineer marks the exact spot on paper.
Cutting Boundary Walls and Garage Entrances in Saihat
A request that comes up again and again on Saihat’s residential streets is widening the garage entrance in a concrete boundary wall, opening a second entrance for an extra car, or adding a pedestrian door beside the main gate. A reinforced concrete boundary wall is cut with the wall saw: two vertical cuts at the sides of the new entrance and a horizontal cut at the base, giving straight edges ready for the gate without breaking that shakes the whole wall.
Because this work happens at the edge of the street, we set cones and barriers at the kerb, and we direct and vacuum the cooling water so slurry leaves no mark on the asphalt or a neighbour’s driveway. Before cutting we ask about any services running inside or beneath the wall, such as outdoor lighting cables, a doorbell or security cameras, and disconnect or reroute them in coordination with the owner.
Before widening a garage entrance
Measure the width of the gate you will fit, including its frame, and confirm where any column sits in the wall. If the new entrance would cut through a column, that is a change we do not make without an engineer, and the answer may be to shift the entrance slightly.
Concrete Cutting and Coring in Saihat for Shops and Homes
Concrete cutting and coring in Saihat is organised differently for a home and for a shop. In a home we are working around a family, so protection, quiet and a full clean-up before we leave come first. In a shop we are working against the clock: the owner wants the doors open on time, so we work before opening, after closing or on the closed day.
■ In houses
Covering furniture and tiles, vacuuming water immediately, and working in hours agreed with the family.
■ In flats
Coordinating with neighbours and the landlord, and protecting the lift and stairs when moving equipment and blocks.
■ In shops
Duct, AC and service openings outside trading hours, without a long closure.
■ In restaurants and commercial kitchens
Larger extract and flue openings, with a rebar scan before coring.
Common shop jobs include opening a rear service door, an opening for a meter or electrical panel, or cutting part of the floor for a new drain when the shop changes its use. All of this can be done with diamond cutting, without turning the shop into a demolition site.
Door and Window Openings Through Concrete in Saihat
A new door or window through concrete in Saihat starts by confirming what kind of wall it is: does it carry the slab above, or is it a partition? In modern flats and houses the drawing shows this; where there is none, we read the thickness and the positions of beams and columns, and the final decision rests with an engineer. Then we mark the opening on the wall to the frame size, install a steel support lintel and vertical props on both sides if the wall is load-bearing, and saw the outline with the wall saw.
In a flat, the cut block is usually not broken up indoors. We pull it out on transport rollers over protection boards and then section it outside the room or remove it whole. That saves noise and dust and protects the floor from impact. After opening, the door frame and edge finishing remain, and this is where we remind you of the steel treatment described in the humidity section.
Wall cutting in Saihat without breaking
Wall cutting in Saihat without breaking is the answer when you want to open the living room onto the majlis, widen a corridor or turn a window into a door onto the courtyard. The wall saw runs on a fixed track, giving a straight line and an edge ready for finishing, and it keeps the surrounding tiles and walls away from vibration. For more detail, see the door and window openings page.
Kitchen-to-living-room pass-through openings
A popular change in modern homes is a serving hatch between the kitchen and the living room, or partly opening the kitchen onto the dining area. This is a rectangular opening of a set width with its sill at worktop height, and we cut it with the wall saw so the bottom edge comes out perfectly straight for the stone top to sit on. If the wall is load-bearing, the engineer specifies the lintel needed above the opening before we cut.
Windows in the façade
A fresh window in an outside wall alters how the house looks from the street, so a permit may be involved. In homes close to the sea we recommend particular care with the new window sill and its fall to the outside, and with sealing the frame, so rain and humidity do not get into the wall around it.
Slab Cutting in Saihat: Skylights, Stairs and Ducts
Slab cutting in Saihat is work we take seriously because it touches a load-bearing slab. A skylight in the roof slab, a stair opening for a new floor, or a duct passing between storeys all need a drawing from an engineer setting out the position, dimensions and strengthening around the opening. We carry it out with the floor saw from the top of the roof or with the wall saw depending on access, with props under the section being cut.
On a roof slab in particular, there are layers above the concrete: waterproofing, thermal insulation and tiles or a protective screed. We cut these layers carefully around the opening and coordinate with the waterproofing contractor to reseal them around the new frame. In a humid coastal climate, any weakness at this point means leaks and damp inside the house later on.
- ✓Skylight: Cut from the roof with the floor saw, with the waterproofing restored around the frame.
- ✓Stair opening: To an approved drawing, with props and strengthening of the edges.
- ✓Duct between floors: Cores at the corners, then the sides sawn, with alignment between floors checked by measurement.
- ✓Lowering the pieces: No piece is allowed to drop; each section is supported and lowered under control.
Floor Cutting in Saihat: Drain Channels and Electrical Runs
Floor cutting in Saihat is needed when a homeowner moves a bathroom or kitchen, adds a sink in the courtyard, or runs a cable to outdoor lighting. The route is drawn as a pair of parallel lines, cut them with the floor saw if the run is long or the hand-held cutter if it is short, and remove only the concrete strip between them. That way the tiles on either side stay intact and the channel is easy to close once the pipe is laid.
In courtyards and parking areas the top layer may be asphalt or interlocking pavers over concrete, so each layer is cut appropriately. We also take the fall of a drain channel from the plumber before cutting, because the depth of the channel changes along its length.
Reinforced Concrete Cutting in Saihat: Scanning for Rebar and Tendons
Reinforced concrete cutting in Saihat starts with a rebar detector that shows where the bars sit inside the wall or slab, so we can place cores between them and gauge reinforcement density before sawing. The diamond blade cuts steel and concrete together, but cutting bars in a load-bearing element is a decision for the engineer, who determines whether the opening needs strengthening.
Some newer buildings have slabs tensioned with steel cables. Those cables carry enormous force, and severing one endangers both the worker and the slab, so we rely on radar scanning to map their route and depth before any coring or cutting. If the slab type is unknown, we ask the owner for the drawing or scan before we begin.
For contractors and site supervisors in Saihat
If your project needs only part of the cutting or coring, our crew and machines handle just that portion, following your drawings and whatever your site engineer instructs, with photos of the cut faces for review.
Cutting a Wall With a Grinder in Saihat: Light Work Only
Cutting a wall with a grinder in Saihat is a sensible choice for specific jobs: an internal block wall, a shallow channel in a bathroom floor, or trimming the edges of an existing opening. For a 20 cm reinforced concrete wall, though, a large hand-held cutter reaches only around 12.5 cm, leaving part of the wall uncut to be broken out, which is exactly what we try to avoid.
That is why we always ask about thickness before choosing the tool. In many cases the wall saw is actually the cheaper option, because it finishes sooner and leaves no broken edges that need render and repair afterwards.
Concrete Saws in Saihat: What We Bring for Each Job
The concrete saw for a Saihat job is chosen by the request, not by what happens to be available. This table links each common Saihat job to the equipment we bring for it:
| Job in Saihat | Equipment | Why |
|---|---|---|
| AC, extract or drain core | Diamond core rig | A precise round hole from about 12 mm up to half a metre |
| Door or window in a concrete wall | Track-mounted wall saw | Ruler-straight cuts, with heavy units reaching roughly 73 cm from a single side |
| Skylight in a roof slab | Floor saw | Cuts from above to a depth of about 24 cm |
| Block wall or edge trimming | 14-inch hand-held cutter | Around 12.5 cm depth is enough for this work |
| Base or thick block | Diamond wire saw | Wraps around the block with no blade-size limit |
| Locating steel and setting out | Rebar detector and laser level | Checks before cutting and accurate marking of the opening |
For clarity: Depths refer to common equipment classes; the real depth can vary with the machine and reinforcement density.
“Laser” Wall Cutting in Saihat: A Quick Clarification
“Laser wall cutting in Saihat” is a phrase many people type, and it usually means a clean, precise cut. But a laser does not cut concrete walls in building work; the cutting is done by a diamond saw, and the laser is a tool we use to draw the lines and set alignment and level before the blade starts. In research settings, powerful lasers have only managed to shave a thin skin off concrete.
The result you want, straight edges and an opening to size, comes from a wall saw following laser-set lines. We unpack the subject properly in our laser wall cutting article.

When Is an Engineer or a Permit Needed for Cutting in Saihat?
AC, extract-fan and plumbing cores generally stay away from the structure, and a check of the location is enough. Work that changes how the building carries its load, such as a doorway in a load-bearing wall, a stair opening or skylight in a slab, or anything touching a beam, is referred to a licensed engineering office for a written report, and a Balady permit may also be required. A new window in the façade changes the building’s appearance and may need a permit as well.
| Work | Usually classed as | What is needed |
|---|---|---|
| AC, fan or plumbing core | Routine, away from the structure | A quick scan for bars and cables |
| Doorway in a partition wall | Normally non-structural | We first confirm it really is a partition |
| Door or window in a wall carrying the slab | Structural | A written opinion from an engineering office, and possibly a permit |
| Skylight or stair opening in a slab | Structural | Engineering drawing and strengthening, and possibly a permit |
| New window in the façade | Change to the building’s appearance | Usually a permit |
| Column or beam | Primary structure | Off limits unless an approved design says otherwise |
The Balady platform has two related services: the Building Restoration Permit, which covers bringing a building back to good order with its structure unchanged, and Adding and Modifying Building Components, for those who want to alter elements of a licensed building. Both require an engineering office. As a rough guide, a wall may be carrying load if it is more than 20 cm thick, sits on a beam or has a column bearing on it; only an engineer can say for sure.
An Occupied Flat or a Working Shop? How We Keep It Clean
Most of our Saihat work happens in places that are lived in or open every day, so cleanliness is part of the job, not an extra. Our diamond tools run wet, the water keeping the blade cool and stopping fine silica dust from getting airborne, but it turns into grey slurry that must not touch the tiles or go down the drains.
- ✓Before starting: We cover floors with sheeting and boards, wrap cabinets and nearby furniture, and clear the area around the opening.
- ✓While cutting: A wet vacuum collects water as it runs, and electrical connections are watertight with residual-current protection.
- ✓Removing the block: Transport rollers over protection boards, or sectioning the block in a way that does not strike the floor.
- ✓When finished: Removing pieces and slurry, wiping down, and handing over the opening ready for finishing.
Common Mistakes With Home Openings in Saihat
- ✓Ordering the frame after the cut: Settle the frame dimensions first and we cut to them exactly.
- ✓Coring an AC hole without a fall: A level hole can send condensate back into the wall.
- ✓Leaving the pipe surround open: A small gap around a pipe is enough to let in water, humidity and insects.
- ✓Delaying steel treatment: In a coastal climate, exposed steel starts to rust before it is finished.
- ✓Opening a roof slab without a waterproofing contractor: Cutting the membrane without resealing it means a leak with the first rain.
- ✓Expecting a grinder to handle a thick wall: It only gets partway, the rest gets hammered out, and the clean finish is gone.
Sectioning the Blocks and Removing Debris After Cutting
The concrete block cut from a single doorway can weigh a great deal, and it should not be left in the middle of a flat or shop. We agree with you before starting whether we take it out whole on rollers or split it into small pieces that are easy to carry, and whether the price includes loading and hauling it off site. If the job is part of a larger renovation that includes demolishing walls or tiling, the demolition and breaking service handles that within the same arrangement.
