Preventing moisture issues

Green Umbrella MoistureBloc5

Green Umbrella® MoistureBloc5™ is a ready-to-use concrete admixture installed at the ready mix facility or on the job site. A chemical reaction is created with cement components that utilize water to close the capillaries and eliminate the route of moisture vapor emission. This reaction is a permanent and integral component of the finished concrete.

MoistureBloc5™ should be added to concrete material when vapor proofing and waterproofing are desired. The treatment will densify, dustproof, and harden the concrete.

By closing the capillary system, a vapor-proof surface is created, allowing the installation of moisture-sensitive coatings and adhesives in a normal construction schedule.


  • Moisture control labor and repairs are eliminated


  • Can install flooring sooner without issues


  • Less construction waste from repairs and damages
