Concrete and Mortar Waterproofer. 

dura.®proof is an additive containing fine particles which combine with the lime in the cement to form water-repellent particles. These obstruct the capillary action within concrete.

All types of cements (except aluminous).

  • Concrete for foundations under the water table.
  • Concrete for reservoirs and tanks.
  • Sealing grout for tanks.
  • Concrete and mortar in regular contact with water.
  • Enhances the waterproofing qualities of concrete, mortar and plaster.
  • Does not modify the characteristics of fresh concrete.
  • Does not affect the compressive strength of concrete.

Stir well before use.


Dosage: 1 L / 50 kg (pocket) of cement.


1 to 3,5kg each 100kg of cement. A 1.5% dosage of the product to the weight of cement is commonly used.


dura.®proof is completely miscible in water. It must be added to the mixing water. The optimum dosage of dura.®proof can only be established after trial tests, taking into account local conditions affecting the workability of the mix and the mechanical properties required from the concrete.
