Why floor & balcony waterproofing differs in Tarout

Team note on Tarout: 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.. Main roads in or near Tarout: Uhud Road, Al Khaleej Road, Al Aimmah Bridge.

The centre of Tarout sits about 3 m above sea level (SRTM open elevation data). Tarout is about 0.9 km from the sea coast (OpenStreetMap).

Restaurants in Tarout tend to run into the same trouble with floors and balconies: water finds its way through worn tiles and failed joints, especially where kitchens, wash areas and outdoor seating get heavy daily use. Grease, hot water and constant foot traffic break down old sealing faster than in a typical home, and the damage often shows first as staining or softness under the floor finish rather than as an obvious leak. Because the surfaces are used all day, small defects can spread quietly before anyone sees a puddle.

Tarout sits about 3 m above sea level, and the centre is about 0.9 km from the sea coast. That low elevation and nearness to the coast mean the ground and the air around a building can stay damp, and salt in the air can speed up wear on exposed surfaces and balcony edges. Because of this, a sound approach starts with checking the whole floor build-up rather than only the visible finish. Crack injection is priced per metre, from SAR 40–120 per m, so it is worth mapping every crack and joint early. For wet zones, epoxy coating at SAR 35–90 per m² or a bitumen membrane at SAR 15–35 per m² are common options, chosen according to how the surface is used and how much movement it sees. Liquid roof waterproofing, at SAR 8–25 per m², suits open balconies exposed to weather.

Before the visit, ask the provider to confirm which surfaces they will inspect and whether they will test for moisture in the slab, not just the tiles. Ask how cracks will be located and sealed, and what preparation of the existing finish is included. Request a written breakdown by square metre and by metre of crack, so you can compare each line with the ranges above. Finally, ask how the work will be scheduled around opening hours, since a restaurant floor usually cannot close for long.

For restaurants, visits are planned outside service hours and recorded for the premises file.

Signs worth paying attention to

If you notice one of these signs in Tarout, it is a good moment to talk to the team:

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

Causes we see in the field

• A blocked drain — we check this before anything else.
• A threshold without waterproofing — we check this before anything else.
• Incorrect falls.

Tools and methods, and when we use them

How the work is done, step by step

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.
