Efflock is a high performance additive to mix at the time of batching for all cement based building materials to repel damp and lock efflorescence.  By controlling water absorption, efflorescence is locked and the potential for waterproofing failure is dramatically reduced.

The Efflock additive creates a hydrophobic molecular structure within the pores of cured concrete without filling the pores of the material. The product dramatically reduces water absorption whilst remaining permeable to allow the controlled release of any moisture. Efflock provides bulk impregnation to protect concrete throughout the entire mass, so that performance is not affected by traffic wear or movement cracks.
