Why water tank waterproofing differs in Taif

The centre of Taif sits about 1673 m above sea level (SRTM open elevation data). Team note on Taif: 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..

Is it worth coating the water tank of a warehouse in Taif, or can the leak simply be patched when it appears? Many property owners ask this because a tank that loses water quietly can damage stored goods and the floor below before anyone notices. In Taif, the centre of the city sits about 1673 m above sea level, a high-altitude setting where daily temperature swings can stress sealants and joints over time. Our work on warehouse water tanks covers the main options so you can match the treatment to the condition you actually find. Internal tank coating is priced at SAR 25–55 per m², epoxy coating at SAR 35–85 per m², and spray foam at SAR 25–45 per m², while crack injection is priced at SAR 40–115 per m.

Our inspection starts with a visual check of the tank walls, floor, and joints to locate cracks, flaking, and areas where the existing lining has lifted. The technician measures the affected surface so the quote reflects the real area to be treated, not a guess. Where a crack is found, it is assessed for length and depth, since crack injection is charged per metre. The team then checks the roof and any connected surfaces that may be contributing to water entry. Based on what is found, the inspection recommends one or more treatments, such as tank internal coating, epoxy coating, or crack injection, and explains why each is suited to the observed damage. Nothing is treated without the inspection report being reviewed with you first.

Before the visit, gather a few details that speed up the assessment. Note the tank's approximate size and its height and width so the surface area can be estimated, and mention when you first noticed the leak or the drop in water level. Tell us what the tank currently holds and whether it is drained for inspection, since a full tank can hide the source of a leak. Share any previous repair records, including dates and materials used. Clear access to the tank lid and the area around it will help the technician work safely. Having these details ready lets the inspection focus on the work that matters and gives you a clear, itemised estimate.

For warehouses, work is phased around operations and stored goods.

When do you need water tank waterproofing?

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

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

Causes we see in the field

• Construction joints — we check this before anything else.
• A common cause: damaged old coating.
• Cracks in the walls or floor — we check this before anything else.

Tools and methods, and when we use them

How the work is done, step by step

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.
