CEMENTITIOUS MIXTURE PROVIDED IN POWDER FORM FOR THE WATERPROOFING OF CONCRETE. WHEN MIXED WITH WATER AND APPLIED AS A CEMENTIOUS COATING, THE ACTIVE CHEMICALS IN THE PRODUCT CAUSE A CATALYTIC REACTION WHICH GENERATES A NON-SOLUBLE CRYSTALLINE FORMATION OF DENDRITIC FIBRES WITHIN THE PORES AND CAPILLARY TRACTS OF CONCRETE. THE PRODUCT THEN BECOMES AN INTEGRAL PART OF THE CONCRETE. THIS PROCESS PERMANENTLY SEALS THE CONCRETE AGAINST THE PENETRATION OF WATER OR LIQUIDS FROM ANY DIRECTION. SUPPLIED IN 500LB (227 KG) STEEL DRUMS.
