DURAHIT® Crystal Ad 3000

Liquid crystalline waterproofing admixture for durable concrete projects

Item No. 3652


DURAHIT® Crystal Ad 3000 is a crystalline waterproofing admixture especially designed for providing a permanent waterproofing system in demanding concrete projects.
The special crystalline technology reduces the capillary diameter and provides a self-sealing effect to the concrete structure. This effect enables concrete to self-heal shrinkage cracks up to 0.4 mm.

DURAHIT® Crystal Ad 3000 is therefore suitable for concrete projects with advanced requirements in durability and quality and where optimum waterproofing is required. Typical applications are:
  • Marine structures like harbours and docks
  • Dams, water reservoirs, water containment structures and swimming pools
  • Tunnel- and underground constructions
  • Waste treatment facilities
  • Basements and foundations
  • Precast concrete
  • Potable water structures

DURAHIT® Crystal Ad 3000 achieves a very effective protection mechanism which provides the following benefits to concrete:
  • Significantly decreased water penetration
  • Subsequent crack minimising
  • Seals existing and future cracks up to 0.4 mm
  • Resits high hydrostatic water pressure from either positive or negative side of the building component
  • Enhances resistance against chemicals and aggressive media
  • Decreased risk of steel corrosion
  • Increases concretes durability and rises its longterm performance
  • May contribute to lower maintenance costs and less replacements

Since DURAHIT® Crystal Ad 3000 advances concrete’s durability, the waterproofing admixture can make a contribution to ecological sustainability.


DURAHIT® Crystal Ad 3000 is a liquid admixture that activates a crystalline reaction with the free lime and moisture in the concrete mix in order to generate permanent and durable crystalline system.

This crystal formation becomes an integral part of the cement matrix allowing concrete to self-heal shrinkage cracks when exposed to water.

These waterproofing properties can provide optimum protection against water ingress.


The dosage of DURAHIT® Crystal Ad 3000 is 5.00% of the total tempering water of the concrete including the moisture of aggregates and sand.

The total dosage range is 0.50 – 4.00% of the cement content by weight.
