Water tank insulation comes in two types: waterproofing that seals cracks in ground tanks, and thermal insulation that reduces the sun's effect on roof tanks. Indicative Riyadh prices start at SAR 450 for roof-tank thermal insulation and SAR 1,800 for ground-tank waterproofing.
Concrete ground tanks crack over time, letting water escape into the soil or contaminants seep in. Roof tanks in a Riyadh summer heat up until tap water is uncomfortable to use.
Waterproofing seals cracks and protects water quality; thermal insulation reduces the sun's effect on tanks and exposed pipes. Our technicians typically clean and prepare the tank, repair cracks and apply the system. Ask about the material and its suitability for drinking-water tanks.

Waterproofing concrete ground water tanks
Most Riyadh villas rely on a concrete ground tank. Over time it develops hairline cracks and leaks at the corners and pipe entries, losing water into the soil or letting dirt in. Proper waterproofing starts with repairing the concrete before any coating.
- Empty, clean and dry the tank, then inspect walls, floor and roof slab for cracks and honeycombing.
- Repair cracks, corners and pipe penetrations first — they are the most common leak points.
- Apply a coating intended for contact with drinking water, such as epoxy or a cementitious membrane, following the manufacturer's instructions. Ask to see the product data sheet.
- Let it cure for the time the manufacturer specifies, run a fill test, then wash and disinfect the tank before use.
- Price depends on tank size, concrete condition and material, and is shown before work starts. Cleaning and waterproofing can be done in one visit.
Why thermal insulation matters in Riyadh
Summer temperatures in Riyadh regularly exceed 45°C. An exposed roof tank absorbs that heat all day, so water reaches your taps hot. Heat also encourages bacterial and algae growth and weakens plastic tanks. Insulation or shading improves comfort and extends tank life.
Benefits of water tank insulation
Each type of insulation does a different job: thermal insulation protects the water from the sun's heat, and waterproofing protects ground tanks from leaks.
- Thermal: slows how fast roof-tank water heats up during the day, so it reaches the taps less hot in summer.
- Thermal: reduces algae and bacteria, which grow faster in warm water.
- Thermal: shields plastic tanks from UV rays that weaken them over time.
- Thermal: reduces repeated expansion and contraction of joints and exposed rooftop pipes.
- Waterproofing: seals cracks in ground tanks, cutting water lost to the soil and higher water bills.
- Waterproofing: keeps groundwater, damp and dirt out of the tank, helping keep the water clean.
- Waterproofing: protects the concrete and reinforcing steel from moisture that corrodes them over time.
- Waterproofing: a smooth surface makes routine tank cleaning easier.
Thermal insulation: everyday comfort in summer
Insulating and shading the roof tank, plus insulating exposed roof pipes, noticeably lowers water temperature — especially for upper floors fed directly from the roof tank.
