Waterproofing Contractor in Damansara Heights

ODSCC is a CIDB G5 waterproofing and concrete repair contractor serving Damansara Heights (Bukit Damansara), Taman Tun Dr Ismail (TTDI), and the surrounding hillside enclaves. We specialise in the two problems that dominate this area: retaining wall and basement seepage on hillside lots, and ageing flat-roof and concrete bungalow elements on the older terraces and bungalows along Jalan Setiakasih, Jalan Damai, and TTDI's grid.

Why Damansara Heights and TTDI buildings face specific waterproofing challenges

This corridor sits on one of the highest ridges in central KL. The geology and the age of the housing produce a very particular waterproofing pattern.

Hillside bungalows with tanked basements (Bukit Damansara core, Jalan Setiakasih, Jalan Beringin). Many Damansara Heights bungalows were built into the slope, with one or two basement levels cut into hillside soil. Original tanking — usually a bituminous or cementitious system applied positive-side during construction — typically starts failing 15-25 years in. Once it does, the basement wall is permanently wet on the outside, hydrostatic pressure builds, and water comes through cracks, cold joints, and around pipe penetrations. The remedy is negative-side: crystalline waterproofing (Penetron / Xypex-style products from SIKA or FOSROC's range) plus PU injection of active leaks.

Retaining walls and pool decks. The same hillside lots almost always have retaining structures supporting terraces, driveways, and pool decks. These take saturated soil pressure for decades. We commonly see efflorescence and damp patches on the inside face of retaining walls, and pool-deck leaks into the bungalow's pool plant room.

TTDI's 1970s-1980s terrace and bungalow stock. TTDI's grid (Jalan Tun Mohd Fuad, Jalan Datuk Sulaiman, Jalan Wan Kadir) has terrace houses now 40-50 years old. Same flat-porch and rear-extension slab issues as Bangsar Baru, plus a wave of recent rebuilds where new owners discover the original concrete slab needs full waterproofing before tiling the new extension.

Premium condos along Jalan Damanlela and Jalan Semantan. The Pavilion Damansara Heights cluster and similar high-end condos add the standard high-rise scope: lift pits, roof slabs, balcony screeds.

What to expect from your free inspection

2. Site visit. We inspect inside and outside, identify the actual ingress path, and check the structural condition of the wall or slab.
3. Written quote with system spec (e.g., "Penetron crystalline + SIKA PU injection at cold joint"), warranty, and timeline.
4. Execution with daily updates and a water-load test where applicable.

FAQ

Do hillside Damansara properties need different waterproofing from flat-land terraces? Yes. A hillside basement wall is permanently retaining wet soil — you cannot solve that with positive-side coating from the inside. We use negative-side crystalline waterproofing that activates in the presence of water and seals from within the concrete matrix, plus PU injection of any active cracks.

My TTDI terrace has a damp patch on the rear-extension ceiling. What's the typical cost? For a standard rear-extension slab, expect RM 5,000-RM 14,000 depending on area, finish, and whether tiles need to be hacked and re-laid.

Can you stop a basement leak without excavating the outside of the wall? Almost always yes. Excavation is rarely viable in Damansara Heights anyway because of mature landscaping and slope. Negative-side crystalline plus PU injection is the standard approach.

Do you serve TTDI condos and JMB-managed buildings? Yes. CIDB G5 means we are tender-eligible and invoice JMBs directly.
