About Hydroseal
30+ years keeping Singapore’s buildings dry
Hydro-Seal Engineering Pte Ltd has been waterproofing Singapore’s homes and buildings since 1995, one of the few contractors that pairs deep waterproofing craft with IRATA-certified rope access under one roof.
Our story
Experience you can’t shortcut
Founded in 1995, Hydroseal has grown into one of Singapore’s most experienced waterproofing and rope-access contractors, with 1,000+ projects completed across private homes, commercial buildings and industrial facilities.
Waterproofing is a craft built on understanding how water really moves through a building. Three decades of solving leaks, including the aftermath of other people’s poor repairs, is why we diagnose before we quote, and why our work is built to last.
Because our team is also IRATA-certified for rope access, we can reach any height to inspect and repair a façade without scaffolding. One company, one point of accountability, one warranty.
