White Tank: Principles of Operation and Advantages
The "white tank" is an advanced waterproofing system used mainly in reinforced concrete works.
This method integrates waterproofing and supporting structure in a single solution, eliminating the need for additional membranes or coatings. It is a particularly suitable technology for underground buildings, foundations, water tanks and sewage treatment plants.

What is the white tank?
The white tank is based on the use of impermeable concrete and construction details that ensure the hydraulic tightness of the entire structure. The term "white" comes from the clear appearance of the concrete when it is completely sealed.
Its effectiveness is due to:
- Low permeability concrete: with the addition of waterproofing additives that improve density and reduce pores.
- Special joints: systems such as waterstop protect critical points such as recovery joints, planned cracking joints or movement joints.
- Careful design details: preventing cracking and seepage.

How to make a white tub?
Creating a white tank requires an integrated approach involving design, high-quality materials, and careful execution:
- Design: it is essential to analyze the soil, water table level and water pressure. Concrete thicknesses are calculated and joint details are defined.
- Concrete preparation: Concrete with waterproofing admixtures, such as crystallizing or water-reducing admixtures, is used. The mix must ensure homogeneity and resistance to hydraulic pressure.
- Joint sealing: Waterstops, bentonite tapes, are applied at recovery and expansion joints. These materials react with water, sealing any seepage.
- Quality control: Each stage is monitored to ensure that the concrete is free of defects such as gravel nests or cracks.

Advantages of the white tub
The adoption of the white tub system offers many advantages:
- Built-in waterproofing: The entire structure acts as a barrier against water, with no need for external coatings.
- Durability: Withstands water and chemical stress, providing protection for decades.
- Reduced maintenance costs: Eliminates the need for periodic work to repair seepage.
- Environmental sustainability: By reducing the use of membranes and plastic materials, environmental impact is lowered.

Applications of white crystallization tank
The white tub is widely used in:
- Foundations of residential and commercial buildings.
- Underground parking lots and underground facilities.
- Swimming pools and water tanks.
- Infrastructure tunnels and tunnels.
