Waterproof Concrete

April 7, 2021

Pouring concrete for the new carwash in Moorooka was no ordinary concrete pour. This pit will be used as a holding tank for carwash operations and it’s maintenance involves shovelling silt from the pit base. A normal water proofing membrane would have torn from the constant shovelling so we partnered with Penetron Australia to provide a concrete with a waterproofing admixture.

Penetron’s admixture consists of Portland cement, very fine treated silica sand and various active, proprietary chemicals. These active chemicals react with the moisture in fresh concrete. The by-products of cement hydration cause a catalytic reaction, which generates a non-soluble crystalline formation throughout the pores and capillary tracts of the concrete. This literally turns the concrete into it’s own living waterproof structure that doesn’t need further internal or external waterproofing products.

When we work together with our clients we’re constantly considering the end purpose of the build. The relationship doesn’t stop when we hand over the keys, we want to make sure a development suits it’s purpose for decades to come.
