Celebrate with us the 20 year anniversary of the Tech-Dry Masonry Blocks!
20 years ago our Tech-Dry scientists had a revelation. In 1996, we made a significant breakthrough in our silicone nanotechnology research and created the admixture Emulsion KR2, which renders dry pressed concrete water repellent and extends its lifespan.
The admixture become a permanent integral part of the concrete for its entire life and makes concrete water repellent.
Emulsion KR2 Admixture
Emulsion KR2 is a concentrated silicone water‑repellent admixture that makes pressed concrete masonry permanently resistant to water and efflorescence. When added during manufacture, it reduces permeability throughout the mix. Blocks, pavers, and other dry‑pressed units stay drier, cleaner, and structurally sound for longer.
Emulsion KR2 suits load‑bearing, decorative, coloured, and retaining wall blocks, as well as concrete pavers and similar masonry. It is not suitable for aerated or wet‑mix concrete. Independent tests show that Emulsion KR2 greatly lowers sponge capillary water absorption compared with oleate and stearate admixtures. It also virtually eliminates efflorescence.

Tech-Dry Masonry Bocks
The benefits of Tech-Dry® Masonry are that it increase the masonry’s longevity, and issues such as mould growth, erosion damage due to the effects of salt from sea spray or salt-chlorinated pools and rising damp are eliminated.
Tech-Dry Masonry is a range of pressed concrete blocks, bricks, pavers, retaining wall units, and tiles manufactured with integral silicone water repellent admixtures. These admixtures use pre‑sealing nanotechnology to significantly reduce water absorption, helping to prevent long‑term efflorescence and concrete mould discolouration that often affect conventional masonry over time. By making the concrete itself permanently water repellent, Tech-Dry Masonry helps eliminate issues such as mould growth, erosion from salt spray or salt‑chlorinated pools, and rising damp in exposed walls.
Let’s have a look at some of the projects and buildings that involve Tech-Dry Masonry Blocks:
