Basement Floor and Wall Sealer-Concrete and Concrete Block

Hydra Block Seals Concrete and Masonry from Water Vapor and Soil Gasses

Hydra Block is a water-based concrete and masonry penetrating sealer that is  vapor impermeable.  The product penetrates below the substrate's surface and reacts with the free lime content to fill the microscopic pores. This hardens the surface and makes it impermeable to water, water vapor and gases such as radon.  Dusting from the concrete or masonry will be reduced or eliminated.

Sealing the interior walls and floors of a basement will greatly reduce the humidity and dampness in a basement.  Reducing the humidity makes for a better environment with reduced musty odors and dampness.

 

Easy Application:

Apply to bare, unsealed, unpainted concrete or masonry.  Adhesives, dirt, oil, grease, paint or any other substance that will prevent the sealer from soaking into the substrate must be removed prior to application.

100% Vapor Impermeable

Hydra-block is 100% vapor impermeable barrier.  Liquid water, water vapor and soil gasses such as radon will not be able to move through the substrate.  When used on the interior of a building, the humidity that arises from water vapor transmission will be reduced.  The dampness and musty odor of basements new and old will also be reduced.
