Our technical recommendations for waterproofing in Al Majmaah
Irregular but sometimes heavy rain
Rain in Al Majmaah is irregular but can arrive heavily in a short time, which is when waterproofing and drainage defects suddenly appear. A preventive check before winter saves the cost of repairs after damage.
Summer–winter temperature swings
Large seasonal temperature swings in Al Majmaah cause repeated expansion and contraction of the roof, so we prefer flexible materials and carefully detail expansion joints to prevent cracking.
Materials we choose from
- Modified bituminous membrane (SBS/APP): Torch-applied rolls, common for roofs and foundations.
- Liquid rubberised bitumen: For foundations and below-grade walls.
- Cementitious and crystalline systems: For tanks, basements and surfaces in constant contact with water.
- Liquid polyurethane coatings: Flexible and seamless, for roofs and complex areas.
Work stages
- Identify the water source and pressure direction
- Prepare the surface and treat cracks
- Primer
- Install the system with correct overlaps
- Protect the waterproofing from mechanical damage
Comparing the available systems
| System | Function | Strength | Needs | Est. SAR/m² |
|---|---|---|---|---|
| Bituminous membrane rolls | Waterproofing | Durable, factory-controlled thickness | Careful laps and protection or mineral-faced rolls | 18–40 |
| Reflective elastomeric acrylic | Waterproof + reflective | Light, quick, ideal for maintenance | Periodic recoating and a sound substrate | 18–40 |
| Spray polyurea | Waterproof + mechanical/chemical protection | Cures in seconds, highly flexible | Specialist rigs and precise surface prep | 70–160 |
| Crystalline cementitious | Integral waterproofing | Works against negative pressure, seals fine cracks | Moist curing and sound concrete | Within tank pricing 60–120 |
| Bitumen coating | Waterproofing for buried parts | Economical and simple | Protection boards before backfill; not for exposed roofs | 15–35 |
Indicative ranges before VAT. A system's real life depends on the product, workmanship and maintenance, so we state it in the written quote and warranty rather than a generic table.
Warranty and compliance
You receive a written warranty whose period depends on the insulation type and surface condition, with a handover report documenting materials and tests (flood, adhesion, thickness).
