The sustainable product which are ideal for single leaf external, parapet, retainer, basement walls and anywhere a water repellant wall is required.
The water-repellent aspect is an integral part of the entire Tech-Dry block and not just a surface effect. An active admix is blended throughout the entire block and will not break down or wash out over time.
Tech-Dry blocks can also be made to order with 40% recycled glass aggregates to provide an environmentally friendly water-repellent block. The feature glass aggregate used in the blocks also results in a unique cost-effective surface finish for no additional cost.
A Tech-Dry mortar additive is supplied to create water-repellent mortar joints to establish a totally water-repellent wall. Tech-Dry blocks are the only accepted industry product that is “waterproof against wind-driven rain’’ as per CSIRO Tech-Dry test results. Tech-Dry blocks have been successfully used in the building industry for over 15 years and comply with relevant Australian Standards.
