Why floor & balcony waterproofing differs in Afif

The centre of Afif sits about 1040 m above sea level (SRTM open elevation data). Main roads in or near Afif: King Abdulaziz Road, King Faisal Road, Airport Road.

Team note on Afif: 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..

Picture a family who has moved into a villa on a sloping plot in Afif, with a tiled balcony off the upper living room and a flat roof that collects the afternoon sun. After the first winter they notice a damp stain spreading across the ceiling below the balcony and hairline cracks along the edge of the terrace. They are not sure whether the problem is the surface, the slab underneath, or the way water is draining away from the building.

Afif sits at roughly 1040 m above sea level, so the town's cooler nights and seasonal rain can cycle a concrete slab through repeated expansion and contraction, which is exactly how hairline cracks open. For a villa owner, this means that a balcony or roof that looks sound in summer may still be letting water through, and that small cracks should be treated early rather than left to widen. Prices for work on these areas vary: crack injection is quoted at SAR 40–120 per metre, liquid roof waterproofing at SAR 8–25 per m², and a bitumen membrane at SAR 15–35 per m², so choosing the right system for the exposed surface matters as much as the cost.

A practical sequence starts with an inspection of the balcony and roof surfaces, marking every crack, ponding area and tile that sounds hollow. Next, sealed cracks should be injected before any surface layer is applied, because a coating over an open crack will fail quickly. Then the drainage outlets and upstands should be cleared and checked so that water runs away from the walls rather than pooling against them. After that, the surface is prepared and the chosen system is applied: liquid roof waterproofing for open roofs, or a bitumen membrane where a more robust layer is needed. Finally, the finished area should be tested with a controlled flood before the tiles or finishes are reinstated, so any leak shows up while the work is still accessible.

In a villa, tanks, the roof and the yard lines are usually yours to look after, so it helps to know where the main valve and tank hatches are.

Signs that call for floor & balcony waterproofing

The following signs are worth checking before they grow:

• Water passing from the balcony to the floor below
• A wrong fall towards the door threshold
• Damp under the light well

Causes we see in the field

• A common cause: a threshold without waterproofing.
• A common cause: incorrect falls.
• A blocked drain.

1. Checking the falls: Where water collects and where it should go.
2. Details: Thresholds, drains and upstands.
3. Waterproofing: The layer is applied and protected.
4. Flood test: Tested before the finish goes on.
