Bathroom waterproofing in Allith: the local context

Main roads in or near Allith: Al Laith Road, Amr Bin Al Aas Street. Allith is about 1.2 km from the sea coast (OpenStreetMap).

The centre of Allith sits about 5 m above sea level (SRTM open elevation data).

Allith sits about 5 m above sea level, and its centre is roughly 1.2 km from the sea coast. Those two facts shape how bathroom waterproofing works here. Because the ground is low and close to the coast, moisture from the air and from the soil stays in the building longer, so bathroom floors and walls face constant damp even when there is no heavy rain. Our crews plan each job around this, checking the substrate for moisture before any membrane or coating goes down, and allowing proper drying time before tiling.

The fact that the centre of Allith is about 5 m above sea level also means that rainwater drains away from some areas more slowly than owners expect. Standing water near the floor edge and at the junction with walls can seep under tiles over time. For this reason we pay close attention to the upstand height at walls, the drain outlet and the joint between the shower area and the rest of the bathroom. The coast at 1.2 km brings salt-laden air, which can attack exposed fixings and weakened grout, so we also seal around pipe penetrations and fittings with care.

Bathroom waterproofing in our Allith work usually falls within a clear range of rates: SAR 15–40 per m² for the full bathroom system, with epoxy coating at SAR 35–90 per m² and spray foam at SAR 20–45 per m² where a seamless finish suits the layout. Crack injection, priced at SAR 40–120 per metre, is often needed before the new system goes on. Owners who plan ahead avoid several common mistakes: they wait until a leak shows on the ceiling below before acting, they tile over a damp surface, they skip the upstand at the wall, and they let cracks in the floor go unrepaired. Booking the work before summer and the rain season gives the materials time to cure properly.

Checks before summer and before the rain season catch problems while they are still small.

When do you need bathroom waterproofing?
