Additive for cement and concrete
HYDROBETON L is a chloride-free liquid admixture formulated to waterproof cement aggregates. During blending of the mix HYDROBETON L exerts a dual action due to the reduction of the W / C ratio and the entraining of evenly spaced micro-bubbles of air that block the pore network, thus waterproofing the aggregate and increasing both its resistance to freeze-thaw cycles and its durability. HYDROBETON L is ideal for structural castings of pools, tunnels, reservoirs, wetlands or areas subjected to water pressure.
Quantity used: from 1.5 to 2.5 kg approx. per 100 kg of cement.
