Waterproofing specialists based at Block 114 Teck Whye Lane, #06-694, in Choa Chu Kang. The firm does basements, roofs, walls, foundations and wet areas for homes, commercial buildings and industrial sites, and serves both private clients and public organisations. Its work ranges from a few hundred square feet to large facilities. The website invites visitors to make an appointment. Customers describe basement waterproofing in a commercial unit as outstanding, with clear communication throughout. A roof repair is praised for ending leaks even in heavy rain, and the team is described as fast and reliable. Another customer says the firm inspected the problem, explained it clearly, and offered affordable pricing. Heavy rain is the test a roof repair has to pass in Singapore, which is why customers mention it. The website also offers janitorial and cleaning services, though the reviews focus on waterproofing.
