Wall damp treatment for rest houses & farms in Abha

Before we start: what we know about Abha

The centre of Abha sits about 2230 m above sea level (SRTM open elevation data). Team note on Abha: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins..

Abha sits about 2230 m above sea level, which gives the city a cooler, wetter character than most of Saudi Arabia. Rest houses and farms in the surrounding hills often face cool nights, sudden rain and heavy condensation, and these conditions drive damp into walls that were built for drier lowland climates. The elevation means that moisture rising through ground-floor walls and condensation on cold surfaces both need to be assessed, not just visible leaks.

Because of this, we begin every job by checking where the water actually enters. A cold, damp wall at altitude may need a breathable treatment rather than a sealed one, so that trapped moisture does not push paint and plaster off the surface. For basements and ground-level storage, basement waterproofing is priced at SAR 50–145 per m², while bathroom waterproofing, often needed in guest rooms, costs SAR 15–40 per m². Spray foam at SAR 20–45 per m² and XPS boards at SAR 10–30 per m² are options where insulation and moisture control must be handled together. Cracks, which the temperature swings of the highlands can widen over time, are sealed by crack injection at SAR 40–115 per metre, and roof leaks are addressed with liquid roof waterproofing at SAR 10–25 per m² or bitumen membrane at SAR 15–35 per m².

Owners of rest houses and farms often avoid the same few mistakes. Many paint over damp patches without finding the source, which only hides the problem until it returns. Others choose a sealed coating on a wall that needs to breathe, trapping moisture behind the finish. Water tanks on farms are sometimes left untreated, and tank internal coating at SAR 25–55 per m² is a sensible step to protect stored water. Epoxy coating at SAR 35–85 per m² suits surfaces that need a hard, washable finish. Waiting until plaster blisters or timber softens usually turns a modest repair into a much larger one, so early inspection is the simplest way to keep costs under control.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

Signs that call for wall damp treatment

The following signs are worth checking before they grow:

• Black spots on the wall
• Peeling paint and salt marks
• A musty smell

Where the problem usually comes from

• A common cause: rising damp from the ground.
• Condensation.
• A common cause: a leaking pipe.

Tools and methods, and when we use them

How the work is done, step by step

1. Moisture readings: Readings are taken in a grid across the wall.
2. Finding the cause: Pipe, condensation or rising damp.
3. Treatment: The cause is treated before the finish.
4. Finishing: Plaster and paint after the wall has dried.
