CHEMFLEX-R100 is a premium water‑based acrylic waterproofing membrane formulated for long‑term protection of concrete roofs, external walls, balconies, and wet areas. Its elastomeric properties allow the coating to bridge hairline cracks, ensuring a seamless waterproof barrier even under thermal movement and structural expansion.
Designed for Malaysia’s tropical weather conditions, Chemflex R100 provides excellent UV resistance, preventing premature degradation and maintaining color stability over time. Its strong adhesion to concrete substrates ensures reliable performance across both new construction and refurbishment projects.
The product’s water‑based formulation makes it environmentally safer, easy to apply, and suitable for both residential and commercial waterproofing systems. With high flexibility, durability, and resistance to ponding water, Chemflex R100 is a dependable choice for contractors seeking a cost‑effective yet robust waterproofing solution.
Why CHEMFLEX-R100
At its core, CHEMFLEX-R100 is a heavy-duty, micro-reinforced synthetic rubber membrane. Its elastomeric structure allows it to stretch and bridge hairline cracks rather than fail at them, so the waterproof layer stays continuous even as concrete expands, contracts, and settles over time. This makes it a dependable choice for both new builds and refurbishment work, where existing cracking is often already a concern.
The membrane is also formulated for outdoor durability. Its UV resistance keeps the coating from breaking down under constant sun exposure, and it holds its colour rather than chalking or fading — an important detail on visible façades, parapets, and roof surfaces. Because it’s water-based, it’s easier and safer to apply than solvent-based alternatives, with no toxic or hazardous substances in the formulation, and it resists blistering once cured.
Chemflex R100 is suitable for:
- Concrete roofs and flat roofs
- External walls and façades
- Balconies and terraces
- Bathrooms and wet areas
- Parapet walls
- Refurbishment waterproofing projects
Performance you can rely on
CHEMFLEX-R100 has been tested and proven against demanding benchmarks: it passes chemical immersion testing (including water and bleach exposure), CSIRO moving joint testing, and accelerated weathering trials. With a dry film thickness of 1mm, the cured membrane can support foot traffic after 8 hours and vehicle traffic after 24 hours, making it practical for sites that need to return to use quickly. Elongation at break exceeds 1000%, giving it exceptional crack-bridging capability compared with rigid coatings.
