Randwick Lightrail Substation

Randwick Lightrail Substation

Approximate value: $160,000

This project was undertaken under the Sydney Light Rail project which involved the installation of over 1000m2 of the Sikaproof A waterproofing membrane. This membrane is a Flexible polyolefin (FPO) which acts as a “blinding membrane”. The membrane is installed first and the concrete is formed and installed after the membrane.

SikaProof® A is an innovative fully bonded sheet membrane system for damp and waterproofing in basement and below ground structures. Its highly flexible polyolefin membrane, with a special sealant grid and nonwoven fleece provide a unique, mechanical bond effect to the concrete structure and prevent any lateral water underflow between the membrane and the concrete.
