Waterproofing Contractor in Petaling Jaya

ODSCC is a CIDB G5 waterproofing and concrete repair contractor serving the whole of Petaling Jaya — from the original old-PJ sections (Section 1 to Section 22) through Damansara Utama, Damansara Jaya, Kelana Jaya, the SS sections, Bandar Utama, Mutiara Damansara, and Sunway. We are IRATEC-certified, authorised SIKA and FOSROC applicators, and we commit to a free site inspection.

Why PJ buildings face specific waterproofing challenges

PJ is Malaysia's oldest planned satellite township, and its housing stock spans more than 60 years. That age gradient is the single most useful lens for waterproofing here.

1950s-1970s old PJ (Section 1, 5, 6, 14, 17, 19). This is the oldest stock — single-storey and double-storey terraces, link houses, and small bungalows. The original flat porch roofs, rear yards, and concrete kitchen extensions were built before liquid-applied membranes were common practice. Most of these slabs are now on their second or third generation of patch repairs, often layers of bituminous paint over old bituminous paint. The right fix is full removal back to bare concrete, primer, and a proper SIKA or FOSROC liquid PU membrane.

1980s-1990s middle PJ (SS2, SS3, SS19, SS20, Damansara Utama, Damansara Jaya, Bandar Utama early phases). These terraces and bungalows are 30-40 years old. Common issues: rear-extension slab leaks where owners added a second storey years ago, flat-roof bungalow porches, retaining walls on the SS19/SS22 slopes, and party-wall ingress between attached terraces.

Newer PJ condos (Mutiara Damansara, Bandar Utama, Tropicana, Kelana Jaya, the Empire Damansara cluster). Standard high-rise scope: lift pits at basement level, roof slab membrane failure on top-floor units, balcony screed leaks, basement carpark slab seepage.

Hillside pockets (Bukit Gasing, SS22, parts of TTDI on the PJ side, parts of Bandar Utama backing onto Kiara hill). These need retaining wall and basement tanking work like Damansara Heights — not just a positive-side coating.

FAQ

What's a typical cost range for a PJ terrace house flat porch or rear-extension waterproofing? RM 4,500-RM 12,000 for a standard scope, depending on area, finish, and whether existing tiles need to be hacked and re-laid.

Do you handle PJ condo JMB tenders? Yes. CIDB G5 grading makes us tender-eligible, and we invoice JMBs/MCs directly.

My old-PJ Section 17 terrace has had bituminous paint applied four times already — is that the problem? Often, yes. Layers of old bituminous coating trap moisture and lose adhesion. We strip back to bare concrete, prime properly, and apply a single liquid PU system with a manufacturer-backed warranty.

Do PJ hillside properties (Bukit Gasing, SS22) need different waterproofing? Yes. Hillside basement walls and retaining walls need negative-side crystalline waterproofing plus PU injection of active leaks, not a positive-side coating from the inside face.
