CRYSTALLINE SLURRY COAT FOR
SURFACE ​WATERPROOFING

HydroCap Powder HP-1 , is a crystal-forming waterproofing slurry coat dry premix that has been widely used over many decades for waterproofing concrete or masonry. On surfaces of existing concrete or masonry, a slurry coat of HydroCap Powder HP-1 ​ is applied using brush or spray. For surfaces of new concrete or masonry,  HydroCap Powder HP-1  is applied using shake-on methods. It is suitable for interior or exterior, below or above grade, positive or negative side surfaces. It is suitable for potable water and subsequent finishing applications.
