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

Before we start: what we know about Albaha

Team note on Albaha: 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.. The centre of Albaha sits about 2178 m above sea level (SRTM open elevation data).

A company that owns a commercial building in Albaha usually relies on rooftop and ground-level water tanks to keep offices, staff facilities and kitchens running. A facilities manager might notice a damp patch on a wall, a brown tint in the water, or a slow drop in pressure, and then need to decide quickly whether the tank itself is failing. The property is often older than the company's current staff, so the tank may have been coated or sealed years ago and has since weathered in the sun and through repeated filling cycles.

The centre of Albaha sits about 2178 m above sea level (SRTM open elevation data), which means the town experiences a cooler, more variable climate than lower coastal cities. Thermal swings between day and night can stress coatings and joints, and high ground often gets stronger sun exposure on exposed rooftop tanks. For a company, this makes it sensible to inspect tank linings and surrounding roof areas on a regular schedule rather than waiting for a leak to appear. Costs also vary by the type of work, so a budget should be set against the actual scope rather than a single assumed figure. Tank internal coating (per m²): SAR 25–60 per m², while liquid roof waterproofing (per m²): SAR 8–25 per m², and crack injection (per metre): SAR 40–120 per m.

Start by drawing up a simple record of the tank's size, age, access points and any past repairs, then walk the exterior and roof to mark cracks, ponding and failed sealant. Next, check the interior for flaking, staining and hairline cracks, and drain the tank to inspect the floor and joints in good light. Decide on the repair route only after this survey: crack injection for isolated lines, liquid roof waterproofing or bitumen membrane for broader roof areas, and tank internal coating for widespread lining failure. Ask for written quantities per square metre or per metre, confirm the work programme so that the tank is out of service for as short a time as possible, and schedule a follow-up inspection to confirm the repair holds.

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

Signs that call for water tank waterproofing

These are the signs most often linked to water tank waterproofing:

• 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.
• Construction joints — we check this before anything else.

How we choose the tool in Albaha

From the first visit to the report

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.
