Crystallising admixture for reducing the permeability of concrete.

Idrocrete KR 1000 is a powdered admixture made from special hydrophilic components which, when added to a concrete mix, reduces the permeability of hardened concrete. Idrocrete KR 1000 is BBA certified as part of the Mapei Idrocrete System - Agrément Certificate 20/5754.

How it works:  When water is added, Idrocrete KR 1000 reacts with the calcium hydroxide and other products that form during the hydration process of the cement to form compounds of calcium silicate and other non-soluble salts. The crystalline compounds and calcium silicate hydrates are deposited in the voids of the cement matrix and reduce its total porosity, thereby increasing the resistance of the concrete to the penetration of water under pressure.

Idrocrete KR 1000 may be successfully used to produce concrete for the following applications: • dams • bridges • car parks • storage tanks • pipes and piles • retaining walls • tunnels • marine structures • basements and foundations • swimming pools • precast elements • white tanks
