Tech-Dry masonry

In 1996, utilizing nano-technology, Tech-Dry's research scientists developed a silicone-based admixture for the use in the manufacture of concrete masonry. It was discovered that the performance of this admixture greatly exceeded that of commonly used stearate- and oleate-based admixtures in the reduction of water absorption and efflorescence.

Since 2001, most block manufacturers within Australia have successfully implemented the use of this admixture in the production of concrete blocks, bricks, pavers and tiles. Its use has revolutionized the way concrete masonry is made water repellent and has led to the development of Tech-Dry water-repellent concrete masonry.

Some of the benefits of specifying Tech-Dry Masonry:

• Surfaces resist long-term efflorescence and remain pristine
• Surfaces resist biological growth due to the masonry remaining dry
• Rising damp at the base of concrete walls is eliminated
• Appearances close to natural stone can be produced
• The building structure remains dry and is environmentally friendly, as evaporation from damp external walls uses energy
• Erosion damage due to the effects of salt from sea spray or salt-chlorinated pools is eliminated
• Masonry remains dry and can be laid in wet weather
• Surfaces exhibit a clean, rather than oily, appearance which can be caused by oil-based admixtures
• Surfaces do not require periodic painting or maintenance, reducing the lifetime costs of the building
• Colour-fast surfaces
• Innovative textures and contemporary colours
