Preparing the surface
Treatment begins with cleaning the surface and filling existing cracks, because a waterproof layer will not bond to an unprepared surface.

The service in Al Ahsa
In a city like Al Ahsa, where the oasis soil is damp and groundwater sits high, foundations absorb moisture readily. Water rises through cracks and joints in the base, carrying salts from the soil to the inner wall surface, leaving white marks and weakening the paint. The team inspects the foundation and lower walls to find entry and leak points, then cleans the surface and applies strong waterproof coating to the foundation from outside and inside as needed.
Al Ahsa is a city in Al-Ahsa governorate in the Eastern Province, close to As Saifa District, Ayn Najm District and Al Muhammadiyah District.
Hairline cracks in the foundation and joints between concrete blocks are the most common paths through which soil moisture enters.

Questions about Foundation waterproofing in Al Ahsa
External waterproofing stops moisture before it reaches the wall, and it is usually applied during construction before backfill. When the building is standing and re-excavation is not possible, internal waterproofing stops rising damp and treats its effects, though it needs a material suited to reverse water pressure.
Foundation damp comes from the soil around the lower wall and rises upward, bringing white salt marks at the base. Roof or bathroom damp descends from above or seeps in from the side, and the marks appear in different places. Identifying the source is the first step in treating it.
Salts show that water is moving through the wall and carrying minerals from the soil or the concrete. Over time the salt crystals expand inside the wall and break down the paint and plaster and can weaken the surface layer of the concrete. The cause needs treatment, not just a new coat of paint.
A water-resistant paint slows how quickly damp shows on the surface but does not stop the movement of moisture inside the wall. The damp and salts keep working behind the coat and it peels before long. True waterproofing resists water pressure from the soil and either bonds into the concrete or covers it with a layer that can hold that pressure.
Tell us which wall shows the damp and whether it is against the soil on the outside, whether you see white salts or peeling at or near the base of the wall, and whether the damp has been there since the house was built or appeared later. These details help us assess the situation before the inspection.
White stains are salts left by water rising from the soil. Water enters through cracks in the foundation, and when it evaporates on the wall surface it leaves the salts behind.
Yes, cracks in the plaster and paint near the base show that moisture is weakening the material. An initial inspection determines whether water is entering from the soil or another source, then the right treatment is chosen.
