Waterproofing for Builders

WSA has been the waterproofing subcontractor for Sydney builders since 2012, on everything from single dwellings and renovations through to multi-residential, commercial and high-rise projects. For a builder, waterproofing is about more than the membrane. It is turning up when the program says, getting it right the first time so there is no rework, and having the paperwork ready when the certifier asks for it.
