Tech-Dry Block Emulsion is a real breakthrough in manufacturing technology. Since it’s creation in 1996, Tech Dry has revolutionised the way masonry is made water repellent.
A silicone-based admixture, Tech-Dry delivers water repellency as an integral part of the entire block or paver – not just a surface effect as with surface sealers.
The active waterproofing material is blended right throughout the block or paver and will not break down or wash out over time.
Demden are New Zealand’s exclusive suppliers of Tech-Dry.
