Our technical recommendations for waterproofing in Dumat Al-Jandal
Irregular but sometimes heavy rain
Rain in Dumat Al-Jandal 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 Dumat Al-Jandal 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).
