SAB® Crystal Mix 211

is a state-of-the-art crystalline waterproofing admixture for concrete, available in powder form. It reacts with moisture and free lime
in the concrete, creating millions of insoluble crystalline fibers, which fill the pores, capillary tracts and minor shrinkage cracks within
the concrete. Passage of water through the concrete, either from the positive or negative water pressure side is permanently blocked
and the reinforcement protected from corrosion.

Usage:

Water Retaining Structures such as water tanks and swimming pools, reservoirs, dams, canals, sewerage & water treatment works
and concrete pipes. Water Excluding Structures such as foundations and shallow basements, tunnels and subways, inspection pits
and lift shafts, retaining walls & civil substructures.

SAB® Crystal Mix 211 can be added to the concrete mix at the time of batching or at the job site or just prior to pour, avoiding
climatic constraints.

• Negative and Positive waterproofing

• Replaces ineffective sheet membranes. 

• Seals shrinkage cracks up to 1/64” (0.4 mm) width. Reduced chloride permeability.

• Treated concrete can withstand hydrostatic water pressure up to 15 meters head.

• Single pack requiring (addition of water on site).

• Non-toxic and suitable in potable water containment.

• Not a vapor barrier - allows concrete to breathe.

• Negligible interference with water reducers & plasticizers.

• Negligible effect/influence on slump and air entrainment.

• Impervious to physical damage and deterioration

• Non-toxic, inorganic, zero VOC (0%)

• Less costly than traditional methods of waterproofing.
