Several possibilities are offered to you by a multitude of products :

• Leak Repair
• Crack Repair
• Construction of a Water Bladder According to Standards
• Waterproof tarp protection
• Building a Pool
• Pool Repair

To ensure the longevity of a hydraulic structure (reservoir, pool, basin), waterproofing must be considered from the design phase. Here are the three essential pillars for a leak-free construction.

1. Protection in Mass : The Hydrophobic Adjuvant

The addition of a mass water repellent (liquid or powder) during the mixing of concrete or mortar is the first line of defense.

• Action: It reacts with the cement's lime to plug the concrete's capillaries.
• Advantage : Significantly reduces water absorption and limits capillary rise.
• Usage: Indispensable for skimmers and peripheral covers of swimming pools and water covers.

2. Mastery of Critical Points : Waterstop Joints and Hydroexpandable Seals

Leaks usually occur at junction points (pouring joints between the floor and the walls).

• Joint Waterstop (PVC): * High-performance flexible PVC profile to be directly cast into the concrete during pouring.
  • Ideal for: Expansion joints and concrete pours subjected to high pressures.
• Joint Hydroexpansive (Bentonite or Acrylic):
  • Appears as a cord to be fixed on the hardened concrete before pouring the next section.
  • Action: On contact with water, it swells (up to several times its volume) to seal off hermetically any liquid passage.
  • Usage: Perfect for radier/ceiling membrane connections and pipe penetrations (wall penetrations).

3. The Waterproofing Coating: Micro-Cement Mortars and Resin Cements

Once the structure is ready, applying a technical coating ensures final waterproofing, even under significant water pressure.

• SikaTop®-209 Reservoir (or equivalent): * Two-component pre-dosed micro-spread mortar.
  • Key points: Excellent adhesion on concrete, certified for contact with drinking water. It remains flexible to bridge any potential micro-cracks.
• Neoflex Imper / Flexible Mortars :
  • Ultra-flexible dual-component cement-based resins.
  • Usage: Ideal for tiled pools or underground reservoirs. Resists counter-pressure (water coming from the outside).
