Our waterproofing materials are food-grade, do not alter water taste or color, and actively prevent germ buildup.
Ticking Time Bombs
What happens when you neglect your underground tank?
An uninsulated tank isn’t just a minor inconvenience; it’s a severe threat to your family’s health and a silent drain on your finances.
Disease Contamination
Cracks allow polluted groundwater and sewage to enter your tank, creating a breeding ground for bacteria that cause skin allergies and intestinal diseases.
Doubled Water Bills
Clean water leaking into the surrounding soil means your water meter spins endlessly to compensate, surprising you with illogical monthly bills.
Foundation Settling
Soil saturation under your home from tank leaks leads to destabilized foundations, sinking courtyard tiles, and dangerous wall cracks.
Health Shield
A smooth layer that prevents algae adhesion and makes future tank cleaning incredibly easy.
Guaranteed Total Purity
Cleaning, Sterilization, and Safe Coating
We don’t just cover up dirt! As a professional water tank insulation company, we fundamentally clean the tank first, then apply “health-safe” insulation layers specifically designed for direct contact with drinking water.
Treating Concrete Voids & Cracks
We seal all gaps and concrete defects with ultra-strong putties that withstand high water pressure, ensuring not a single drop leaks.
The Glass-Like Isolation Layer
We coat the interior with an advanced, solvent-free insulating material. It dries to form a smooth, glass-like surface that prevents water from interacting with the tank’s walls.
Comprehensive Coverage
We Insulate All Types of Tanks
Our extensive experience makes us highly capable of handling all water storage systems efficiently.
Underground Tanks (Concrete)
The primary reservoir for the home and the most prone to issues. We drain, dry, and treat the floor and walls with pressure-resistant coatings to prevent drinking water from mixing with sewage.
Upper Tanks (Fiberglass & Plastic)
Roof tanks are exposed to intense sun heat which can cause cracking. We offer exterior insulation to reduce water temperature, and interior treatments to seal micro-punctures.
Complete Washing
Removal of silt and dirt
Anti-Bacterial Sterilization
Protection from intestinal diseases
Save Money
Stop waste and high water bills
10-Year Warranty
On work quality and materials
Because Your Health Accepts No Errors
Tank Cleaning & Insulation Process
Our strict protocols guarantee the highest levels of efficiency and safety.
Water Extraction & Drying
We use powerful submersible pumps to completely empty the tank of water, then ventilate and dry it thoroughly to begin work in a moisture-free environment.
Washing & Sediment Removal
Technicians descend into the tank to remove mud, dirt, and algae stuck to the walls, washing the concrete surface thoroughly to expose any hidden cracks.
Treatment & Insulation Layer
Cracks are sealed with specialized “polymeric cement,” then walls and floors are coated with two layers of safe insulating material to form a robust shield preventing leaks.
Final Sterilization & Testing
After the insulation dries, the tank is sterilized with safe agents to eliminate microbes. We then test it with water and hand it over ready for clean, safe use.
Don’t Compromise on Health

| Bacteria & Algae Buildup | Smooth layer entirely prevents adhesion | Rough surface where green algae thrives |
| Durability & Leak Prevention | Flexible and withstands high water pressure | Peels and cracks after a short period |
| Ease of Future Cleaning | Washes easily with just clean water | Very difficult due to dirt trapped in pores |

Frequently Asked Questions
How do I know my underground tank needs waterproofing?
The most critical signs are: a sudden and massive spike in your water bill, your water pump running continuously to compensate for the loss, and a change in the smell and color of the water due to soil and groundwater entering the tank through cracks.
Do I need to empty the tank myself before you arrive?
Not at all! Our teams are equipped with extremely powerful extraction pumps. We will draw out all remaining water and completely empty the tank upon arrival to begin the washing and drying process immediately.
Do the materials used change the taste of drinking water?
Absolutely not. As a certified tank waterproofing company in Riyadh, we exclusively use materials authorized and dedicated for drinking water (food safe and solvent-free). Therefore, they do not react with water or alter its taste or color whatsoever.
When can I refill the tank with fresh water?
Usually, you wait for 24 to 48 hours maximum. This duration is sufficient for the insulation layer to dry completely and harden. Afterward, we wash and sterilize the tank, making it ready for safe filling and use.
