Waterproofing Concrete Integral Concrete Waterproofing – Hydro admixture manufactured by Specon Inc. is a waterproofing admixture formulated for use in concrete. Concrete to be waterproofed shall be designed for maximum denseness and
strength and shall contain a dosage of 1½ gallons per yard of Hydro admixture. Greater cement volume, greater water utilization, and decreased water demand produces less capillaries, less shrinkage, and a
denser, impermeable concrete.Damproof Concrete Slabs On Grade –
Hydro for slab on grade damproofing in lieu of poly sheeting. Concrete dosed with 1 gallon per yard of Hydro admixture is very effective for slab on grade damproofing by reducing water vapor transmission through concrete by almost one half, at the same time increasing compressive strength by up to 28%. A concrete damproofed with Hydro has a perm rating of 0.413 and exceeds the recommendations of ASTM C 755 by a factor of 10. Plastic sheets are subject to tears and punctures during placing and also chemically break down in time.
