Waterproofing Contractor in Bangsar

ODSCC is a CIDB G5 waterproofing and concrete repair contractor working across Bangsar — from the original terrace stock in Bangsar Baru to the bungalows along Lorong Maarof and the hillside lots above Jalan Bangsar. We are IRATEC-certified, authorised SIKA and FOSROC applicators, and we commit to a free site inspection of your WhatsApp.

Why Bangsar buildings face specific waterproofing challenges

Bangsar's housing stock has three distinct age and topography profiles, and each produces a different waterproofing pattern.

1960s-1980s terrace and link houses (Bangsar Baru, Lucky Garden, Bangsar Park). Most of the original Bangsar terrace stock is now 40-60 years old. The flat porch roofs, rear-extension slabs, and concrete parapets were built before modern liquid-applied membranes existed — they typically only have a bituminous coat or none at all. Owners who have renovated and added a second-floor extension over the back kitchen often discover the original slab leaks within a year or two of the renovation, because the new tile finish traps water on top of an un-waterproofed slab.

Hillside bungalows (Lorong Maarof, Jalan Ara, the slopes off Jalan Bangsar towards Damansara Heights). Bangsar's western edge runs up onto the same ridge as Damansara Heights. Properties here have substantial retaining walls and tanked basements. Once the original tanking fails, hydrostatic pressure pushes water through hairline cracks year-round — not just in monsoon season. Negative-side crystalline waterproofing and PU injection are the standard remedies.

Mid-tier and luxury condos along Jalan Maarof and Jalan Ara (e.g., the Bangsar Heights / Park Residences cluster). These face the same lift pit and roof slab issues as any KL high-rise, but Bangsar condos tend to have more elaborate pool decks and roof gardens that complicate roof waterproofing.

FAQ

My 1970s Bangsar Baru terrace has a leaking flat porch roof. Can it be done without demolishing the porch? Usually yes. We strip the existing finish, prime the slab, apply a SIKA or FOSROC liquid PU membrane, and re-tile or apply a coloured topcoat. Two to four days on site for a typical terrace porch.

Do hillside Bangsar properties need different waterproofing? Yes. Properties on the slope share Damansara Heights' challenge — basement walls retaining wet soil year-round. We use negative-side crystalline (e.g., Penetron-style products) plus PU injection of active leaks, not just a positive-side coating.

What's the cost range for a terrace house in Bangsar? A flat porch or rear-extension slab waterproofing job typically runs RM 4,500-RM 12,000 depending on area and condition. Bungalow scopes vary widely; we quote after inspection.

Do you handle JMB tender work for Bangsar condos? Yes. CIDB G5 means we invoice JMBs directly and can attend committee meetings.
