Lift Pit Waterproofing in KLCC

01 / Overview

Lift Pit Waterproofing for KLCC buildings.

KLCC towers run lifts to 50+ floors, and a leaking lift pit at the bottom puts the entire shaft at risk. ODSCC waterproofs KLCC lift pits using crystalline systems (PENTENS Crystalline Plus, FOSROC Brushbond RFX) plus PU injection for active leaks. CIDB G5, IRATEC-certified, and an authorised applicator for SIKA, FOSROC, MAPEI, BOSTIK, PENTENS and DENKA construction-chemical systems.

02 / Why KLCC

Local building stock & failure patterns.

The KLCC enclave — covering Jalan Ampang, Jalan P. Ramlee, Jalan Pinang and the Persiaran KLCC ring — has some of the highest building-density-to-water-table ratios in Kuala Lumpur. Many of the original luxury condo towers (e.g., around the Park Royal and Suria KLCC perimeter) are now 15–20 years old, and their deep basement lift pits sit several metres below the Sungai Bunus catchment groundwater level. The basement carparks here typically go three or four floors deep, and the lift pits at the very bottom take constant hydrostatic load. Once the original negative-side waterproofing fails — usually first at cold joints between pour stages — groundwater seeps in continuously, not just seasonally. Building managers usually notice it as standing water in the pit during the JMB monthly inspection, often combined with rust on the buffer springs. KLCC lift maintenance contracts are typically held by the original lift OEM (KONE, Otis, Mitsubishi) and they are quick to flag a wet pit as a warranty-voiding condition. We work with JMBs and the lift maintenance team to schedule the repair without taking the lift out of service for any extended period.

03 / Typical scope

What we deliver on site.

KLCC lift pit scope: dewatering, leak-path mapping with the lift held above, PU injection along cold joints and tie-bolt holes until the pit holds dry, then a two-coat crystalline system on the negative side, plus a cementitious top coat. We coordinate parking with the lift OEM each morning. Premium KLCC buildings sometimes require additional documentation for the JMB and insurance — daily progress sign-off, material certificates, and a final water-hold test report. Typical KLCC lift pit job: 4–7 days from dewatering to handover.

04 / FAQ

Questions from KLCC clients.

• Will the lift OEM (KONE, Otis, Mitsubishi) accept the repair?

  We use manufacturer-approved crystalline and PU systems and provide the material certificates the lift OEM requires for warranty continuity. We have done this on multiple high-rise KLCC towers.

• Can the building avoid taking the lift out of service?

  The car parks above the pit during application. The lift itself stays in service for the floors above; the affected floor is sometimes skipped for one to two days during top-coat curing.

• Do you provide a written material spec and warranty document for the JMB?

  Yes. Every KLCC project we quote comes with a written technical opinion, material spec sheet, warranty terms, and a final hand-over report including a water-hold test result.
