Underground Reinforced Concrete Water Tanks

Underground tanks are the most common choice for Saudi homes cooler water, no lost yard space, and decades of service when properly waterproofed.

Why an underground concrete tank?

  • Water stays cooler in summer because the soil insulates it.
  • It does not take up yard space or spoil the façade.
  • Reinforced concrete withstands soil pressure and loads above it.
  • Easy to fill from water trucks or the mains.

Waterproofing matters most underground

An underground tank is surrounded by soil, moisture and sometimes groundwater. Without external waterproofing, moisture and salts can enter or water can leak out. That is why every tank we make is bitumen-coated outside and chemically lined inside. Read more in our waterproofing guide.

What do you need before installation?

An excavation slightly larger than the tank, a level compacted base (or concrete slab), and crane access. Send us photos and we will advise. See our site preparation guide.
