ROCKPROOF W.P.C 20 KG BAG(S) | NASIR & SONS VERTEX CHEMICALS PAKISTAN

DESCRIPTION : ROCKPROOF WPC is a hydrophilic crystalline admixture in dry powder form. ROCKPROOF WPC is used to protect concrete structures against moisture transmission, chemical attack and corrosion of reinforcing steel. When combined with fresh concrete, ROCKPROOF WPC unique and proven technology reacts with un-hydrated cement particles to form millions of needle-like crystals. Over a period of weeks and months, these crystals grow, filling the naturally occurring pores and voids in concrete, and permanently blocking the pathways for water and waterborne contaminants. Later, if cracks form due to settling or shrinkage, incoming water triggers the crystallization process and additional crystals form, filling cracks and ensuring that the structure’s waterproofing barrier is maintained and protected. – In addition to filling the pores and capillaries of the concrete matrix with crystals, WPC enhances the natural hydration process by intensifying and prolonging the hydration of the cementing materials. This reduces the size and number of capillary pores within the concrete matrix, making it dramatically less porous and improving strength and durability characteristics. More over it disrupts the cellular network within the concrete and mortar mass, which are normally interconnected thereby reducing permeability. – Provides resistance to water penetration either under hydrostatic pressure or capillary absorption. – Imparts integral watertightness to structures – Protects from waterborne corrosive agents. – Permanently active – crystalline action is reactivated by contact with water. – Equally effective against both positive and negative water pressure or osmotic pressure. – Reduced sulphate attack. – Reduced efflorescence. – Does not reduce compressive strengths – Powder – easy to use in pre-batched renders. – Low dosage – Economical.
