High-Rise Roof Waterproofing & Repair

High-Rise Roof Waterproofing & Repair | Refurbishment MMT Sdn Bhd (RMMT)

Refurbishment MMT Sdn Bhd (RMMT) provides high-rise roof waterproofing and repair services for condominiums, commercial buildings, office towers and other existing properties in Kuala Lumpur and Selangor.

Roof leakage is a common problem in existing buildings. Ageing waterproofing membranes, deteriorated joints, cracks in the roof substrate and defective waterproofing details can allow rainwater to penetrate the building structure, resulting in ceiling stains, damp surfaces and damage to interior finishes.

RMMT specialises in roof waterproofing works using membrane-based waterproofing systems to help protect building roofs against water ingress. The appropriate repair method depends on the existing roof condition, substrate, extent of deterioration and project requirements.

1. Roof Inspection & Defect Assessment

Before waterproofing work begins, the roof condition should be assessed to identify visible defects and determine the appropriate repair approach.

Our scope may include:

• Inspecting existing roof surfaces and waterproofing membranes.
• Identifying visible cracks, blisters, peeling membranes and deteriorated areas.
• Checking waterproofing details around roof edges, upstands and penetrations.
• Assessing visible signs of water ingress and damaged waterproofing sections.
• Determining whether localised repairs or broader waterproofing renewal may be required.

2. Waterproofing Membrane Installation

Waterproofing membranes form a protective barrier that helps prevent rainwater from penetrating the roof structure when correctly selected and installed.

Our membrane waterproofing works may include:

• Preparing the roof substrate before waterproofing installation.
• Removing loose or deteriorated materials where necessary.
• Applying a suitable primer or preparation treatment according to the selected system.
• Installing waterproofing membrane materials appropriate for the roof and project specifications.
• Treating membrane joints, overlaps, corners and termination details.
• Ensuring appropriate detailing around roof penetrations and adjoining surfaces.

The membrane type and installation method will depend on the specified waterproofing system and actual site conditions.

3. Existing Roof Waterproofing Repair

Where the existing waterproofing system has deteriorated or developed localised defects, appropriate repairs may help restore its protective function.

Repair works may include:

• Repairing damaged or deteriorated membrane sections.
• Rectifying defective membrane joints and overlaps.
• Addressing localised waterproofing failures.
• Repairing suitable roof-edge and upstand details.
• Replacing damaged sections where patch repairs are insufficient.

The existing membrane condition should be assessed before deciding whether localised repairs or more extensive replacement is appropriate.

4. Roof Leakage Rectification

Roof leakage can occur around membrane joints, roof penetrations, drainage outlets and other vulnerable details.

Proper rectification involves identifying the likely source of water ingress before selecting the repair method.

Our work may include:

• Assessing visible roof leakage and waterproofing defects.
• Inspecting vulnerable membrane joints and connection details.
• Repairing defective waterproofing sections.
• Checking the repaired areas using an appropriate inspection or testing method, where applicable.

Water entering through external walls, windows or other building components may require separate investigation and rectification.

5. Suitable Buildings

Our high-rise roof waterproofing services are suitable for:

• Condominiums and apartment buildings.
• Commercial and office buildings.
• Residential developments.
• Industrial and institutional buildings.
• Existing buildings requiring roof waterproofing maintenance or refurbishment.

6. Why Is Proper Membrane Installation Important?

The performance of a waterproofing system depends on more than the membrane material itself. Substrate preparation, membrane compatibility, joint treatment, installation quality and termination details all influence the final result.

Selecting a suitable system and addressing the underlying defects can help reduce recurring leakage and protect the building against moisture-related deterioration.

For property owners, JMBs, MCs and facility management teams, proper assessment before repair also helps determine the appropriate scope of waterproofing work.
