Tech-Dry manufactures a range of water repellent / waterproof admixtures for concrete and/or concrete masonry.
For dry-pressed concrete such as concrete blocks, pavers and roof tiles:
BLOCK EMULSION is the most popular silicone water repellent / waterproof admixture in Australia and for dry-pressed concrete masonry including concrete blocks and pavers. When Block Emulsion is incorporated into pressed concrete products, the permeability to water and the occurrence of unsightly efflorescence is virtually eliminated.
EMULSION KR2 is a concentrated silicone water repellent / waterproof admixture similar to Block Emulsion for dry-pressed concrete similar to that of Block Emulsion.
For wet-cast concrete including pre-cast concrete, fibro cement board, and other wet-cast concrete products:
TECHDRYAD SUPER is a silicone water repellent / waterproof admixture designed for wet-cast concrete or similar applications. It may also be used for dry-pressed concrete masonry.
POWDERSIL 50 is a free-flowing powder silicone water repellent / waterproof admixture particularly useful in grouts, joint fillers, mortar and facade rendering applications. The admixture can be pre-blended with dry ingredients of cementitious materials to provide hydrophobic properties to the finished products.
General-purpose water repellent / waterproof admixtures for mortar or cement render:
MORTAR ADDITIVE is an aqueous admixture for cement and mortars specifically formulated for laying water repellent concrete blocks or Tech-Dry Masonry. It not only makes the mortar water resistant, but also improves the adhesion of the mortar to the water repellent blocks and improves the workability of the mortar mixture.
SALT RETARDER is a 3 in 1 admixture for cement render similar to that of Mortar Additive. This product is recommended for the cement render after Tech-Dry Damp Course installation.
