Commercial Flat Roof Waterproofing at DSG Malaysia, Banting
Project Overview
Manufacturing facilities with office spaces require waterproofing systems that protect both operational areas and working environments.
At DSG Malaysia in Banting, ARCHTECH was engaged to carry out flat roof waterproofing works covering 1,920 square feet, where roof leakage posed a risk to office interiors, production continuity, and equipment protection.
In factory settings, even minor roof leaks can lead to workflow disruption, asset damage, and rising maintenance costs, making long-term waterproofing reliability essential.
Project Type: Manufacturing Office & Factory
Area Covered: 1,920 sq ft
Waterproofing System: Primer + Torch-On Membrane
Site Conditions & Waterproofing Challenges
During the site inspection, several waterproofing issues were identified on the flat roof area above the office and factory spaces:
- Early-stage surface cracking, allowing water to seep into the concrete slab
- Localised water ponding, increasing stress on the roof surface
- Deteriorated waterproofing, caused by the use of unsuitable materials and inconsistent workmanship from previous applications
- Reduced adhesion and surface breakdown, limiting the effectiveness of the existing waterproofing layer
- Active workspaces below, where ongoing leakage posed risks to operations and staff comfort
In this case, the waterproofing failure was not only due to age, but also the lack of a properly designed system and controlled application, leading to premature deterioration under weather exposure.
Waterproofing Strategy & System Selection
After evaluating the roof condition and operational requirements, ARCHTECH recommended a primer and torch-on membrane waterproofing system, selected for its proven durability and suitability for industrial and office flat roof applications.
This system was chosen to provide:
- Strong, consistent waterproofing protection
- Resistance to prolonged sun exposure and weathering
- Long-term performance with minimal maintenance
Torch-On Membrane Waterproofing System Details
System Build-Up
- Layer 1: Primer
Applied to prepare the concrete substrate and enhance bonding between the roof surface and waterproofing membrane. - Layer 2: Torch-On Membrane
Heat-applied waterproofing membrane installed using controlled torching to ensure proper adhesion, sealed overlaps, and uniform coverage across the roof.
This system delivers consistent thickness and reliable protection, making it suitable for factory and office environments exposed to daily weather conditions.
Application Methodology
All works were carried out by ARCHTECH’s trained and qualified in-house specialists, following a structured process.
Step 1: Surface Preparation & Rectification
Roof surfaces were cleaned thoroughly.
Cracks, uneven areas, and weak points were identified and rectified to improve bonding and reduce the risk of water ponding.
Step 2: Torch-On Membrane Installation
Torch-on membrane was installed with controlled heat application to:
- Achieve secure bonding to the substrate
- Ensure sealed joints and overlaps
- Maintain uniform membrane thickness
Critical areas such as joints, edges, and drainage points were carefully detailed to reduce future leakage risks.
Workmanship & Quality Control
For factory and office buildings, waterproofing performance depends heavily on application accuracy and consistency.
For this project:
- Waterproofing works were executed by professionally trained and qualified in-house specialists
- Materials used were SIRIM-certified and Green-certified
- Installation followed industry-accepted waterproofing standards
- Continuous supervision ensured workmanship quality across the entire roof area
Based on the certified system and controlled execution, this waterproofing work is backed by a 10-year warranty, providing long-term assurance for the facility owner.
Results & Performance Outcome
Upon completion:
- The 1,920 sq ft flat roof area was fully sealed
- Water ingress risks were significantly reduced
- Office and factory spaces below were protected from leakage
The completed waterproofing system now delivers long-term protection, supporting stable daily operations and reducing future maintenance concerns.
