Waterproofing & Insulation in Saudi Arabia, dry, cool and protected
Anas Al Khaleej Company waterproofs roofs, bathrooms, basements, tanks and foundations, and adds thermal insulation that keeps buildings cooler and lowers the load on air conditioning.
Most leaks come from details, not from rain
Rain in Saudi Arabia is not frequent, but when it comes it is heavy. Roofs without proper falls, drains and upstands hold water and leak through cracks and joints.
Bathrooms, kitchens and water tanks cause even more damage because they leak every day, often hidden until tiles lift or ceilings stain.
We waterproof with the right system for each area, detail the corners, drains and joints carefully, and flood test before anything is covered.

Waterproofing systems we use, and where
We choose the system for each area. Product and thickness are confirmed in your written quote.
| System | Best for | Typical application | Key benefit |
|---|---|---|---|
| Bitumen membrane | Roofs, foundations, basements | Torch-applied sheets | Proven, tough and durable |
| Polyurethane (PU) liquid | Roofs, terraces, balconies | Seamless liquid coat | No joints, follows complex shapes |
| Cementitious coating | Bathrooms, tanks, basements | Brush or trowel applied | Bonds to concrete, good for wet areas |
| Acrylic / elastomeric | Walls, parapets, small roofs | Roller applied | Flexible, bridges fine cracks |
| Insulation boards | Roofs and walls | Laid over membrane | Reduces heat gain and cooling cost |
Our waterproofing process
Inspect & diagnose
We find the leak source or review the new-build details.
Surface preparation
Cleaning, repairs, screed to falls and priming.
Detail work
Drains, corners, upstands and joints reinforced first.
Membrane & insulation
Main system applied, then insulation where specified.
Flood test & protect
Water test, then protection layer or tiles.
How much does waterproofing cost?
Waterproofing is usually priced per square metre, based on the system, area and condition. Leak repairs are priced after inspection.

Waterproofing and insulation questions
How do I know if my roof needs waterproofing?
Stains on ceilings, peeling paint, damp smells, cracked roof screed or water standing on the roof after rain are common signs. We can inspect and confirm.
Which waterproofing is best for roofs in Saudi Arabia?
Bitumen membranes and polyurethane liquid systems are both common for roofs. The choice depends on the roof shape, traffic, budget and whether insulation is added.
Does roof insulation really reduce heat?
Yes. Insulation reduces the heat that passes through the roof into the rooms below, which helps the air conditioning work less.
Can you fix a bathroom leak without removing all tiles?
Sometimes. It depends on the leak source. We inspect first and remove only what is needed to repair the waterproofing properly.
What is a flood test?
After waterproofing, we hold water on the area for a set time to check for leaks before tiles or screed cover the membrane.
Do you waterproof water tanks?
Yes. We waterproof underground and roof tanks with suitable coatings for water retention.
How long does waterproofing last?
A properly installed and protected system lasts many years. Life depends on the system, exposure and whether it is protected from sun and traffic.
