The reinforced thin-layer drainage
with triple effect for solid laid ceramic tiles and plaques.

Watec®3E reliably and permanently drains, ventilates and uncouples outdoor ceramic coverings, providing secure protection from frost damage and efflorescence caused by accumulated water in cavities in the thin-bed mortar. Delamination and cracks in the covering due to shear stresses in the substrate caused by weather conditions are avoided, thanks to the 100% uncoupling of the floating laid system.

Advantages of Watec® 3E

  • Unique combination of floating laid and thin-layer covering thanks to tear-proof mesh on the top.
  • Triple protection : drainage, ventilation and uncoupling.
    Quick drainage and ventilation provides reliable protection from frost damage and efflorescence due to accumulated water. 100% uncoupling from the substrate guarantees effective protection from cracks in the covering and delamination due to shear stresses caused by weather conditions.
  • The best drainage performance.
    In comparison to other thin-layer drainage mats  (German Institute for Textile Construction and Environmental Technology (tBU Greven)).
  • Ideal for renovation work due to the low construction height of approx. 16 mm including covering.
  • 5 year system warranty.
