Applied Technologies is a company that focuses on creating products that help waterproof your concrete, preventing moisture penetration and the various problems associated with that. Their Hydra-Block sealer is an example of that mission, protecting your concrete walls and floors from water, water vapor, radon, and methane gas.
The Hyrda-Block sealer is a water-based sodium silicate sealer. Sodium silicate sealers are penetrating solutions whose small particles of silicate will penetrate past the surface of the concrete into the material. Other sealers, such as acrylics, will not penetrate past the surface, leaving instead a protective film that will prevent moisture from seeping into the concrete from that one direction. For penetrating sealers, however, the particles will react chemically inside of the material to fill in the air bubbles found naturally in concrete, decreasing porosity while increasing protection.
The sealer will help harden the material and decrease concrete dusting, all while preventing the incursion of moisture and harmful gases. The sealer can be used on brick and masonry, as well as concrete and concrete blocks. With a dry time of 1-2 hours, Hydra-Block is a flexible and viable option for any project requiring a sodium silicate sealer.
