Water tank waterproofing in Tarout: for companies (annual contract)

Prepared by the technical team · editorial review · last updated 13 November 2026 · Sources

Before we start: what we know about Tarout

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

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

For a company that operates a commercial site in Tarout, the water tank is a critical asset. Facilities managers usually handle a cluster of tanks serving offices, staff facilities, and process areas, and they expect them to hold water safely year after year. The typical owner in this situation wants the tank sealed, the interior protected, and the work scheduled so that daily operations are not interrupted. They also need a clear basis for comparing quotes from different contractors.

Tarout sits about 3 m above sea level, and its centre is about 0.9 km from the sea coast. For a business owner, this means the tank is close enough to coastal air to face salt-laden humidity, yet it is low-lying and sits in a flat area where moisture can linger around the base and foundations. Both factors put pressure on coatings and joints over time. Owners should therefore look at the tank's interior lining, the wall-to-floor junction, and any cracks as priority items, because salt and moisture work into weak points faster than many expect. Planning the inspection around these risks is a sensible way to spend a maintenance budget.

A practical sequence starts with a full inspection of the tank interior and exterior, marking every crack and failed joint. Next, cracks are sealed by crack injection, which is priced per metre at SAR 40–120 per m, so measuring the total crack length gives a realistic estimate. The internal surface is then treated with a tank internal coating at SAR 25–60 per m², or an epoxy coating at SAR 35–90 per m² where a harder finish is needed. Where the tank sits on or near a basement or sub-structure, basement waterproofing at SAR 50–150 per m² may also be relevant. Finally, the owner should request written quotes that state the area measured per m², confirm the curing time before refilling, and schedule a follow-up check after the first full fill cycle.

For companies, an annual contract sets the scope, the visit schedule and the reports in writing.

Signs that call for water tank waterproofing

The following signs are worth checking before they grow:

• Deposits and flaking inside the tank
• A tank that leaks after testing
• Unusual colour or taste in the water

The most common causes

• Cracks in the walls or floor — we check this before anything else.
• Damaged old coating — we check this before anything else.
• Construction joints.

How we choose the tool in Tarout

The steps in order

1. Emptying and ventilation: The tank is emptied and ventilated before entry.
2. Cleaning and preparation: Loose material is removed down to a sound surface.
3. Crack treatment: Active cracks are treated first.
4. Coating layers: A material intended for drinking-water tanks is applied.
5. Disinfection and fill test: The tank is disinfected and the level is monitored after filling.
