Waterproofing Works in Singapore
Roof, toilet & wet-area waterproofing membranes engineered for Singapore's climate. Licensed Singapore specialists delivering waterproofing works for HDB, condominium, commercial and industrial properties with manufacturer-backed warranty.
Professional waterproofing works you can rely on
Waterproofing Works is a critical part of any Singapore building's long-term performance. In our tropical climate — with driving monsoon rain, high humidity and constant thermal movement — even small defects escalate quickly into structural damage, mould and costly reinstatement.
At HRN Waterproofing & Renovation Pte Ltd (UEN 202318739G), our waterproofing works team combines site-tested experience with manufacturer-approved systems. Every scope is diagnosed on-site first, quoted transparently line-by-line, and delivered by trained applicators under WSH-compliant safe work procedures.
Whether you are a home owner dealing with recurring leaks, a managing agent planning cyclical maintenance, or a main contractor coordinating fit-out works, our specialists handle the full building envelope in-house — waterproofing, coatings, sealants, concrete repair and reinstatement — so you deal with one accountable partner from survey to handover.
