YOUR BITUMEN ROOF IS FAILING. WE FIX IT. PERMANENTLY.

System To Repair & Waterproof Failing Bitumen on Flat Roofs


Cold-applied bitumen waterproofing — bituminous paint, bitumen emulsion and bitumen felt — deteriorates over time. It blisters, cracks, delaminates and dries out. The ArmTec HyperFlex system bonds directly over the failing bitumen substrate — no stripping, no mess, no disruption — delivering a fully bonded, seamless waterproof membrane over the top.

WATERPROOFING SYSTEM

ARMTEC HYPERFLEX - BITUMEN RENEWAL SYSTEM

The existing bitumen stays in place — no stripping, no removal, no disposal. UltraBond WP is applied first to seal the bitumen and prevent off-gassing that would cause system failure. The ArmTec HyperFlex system is then installed over it — HyperFlex embeds the mesh, HydroSeal HF delivers the seamless waterproof membrane.

ArmTec HyperFlex System to repair the bitumen waterproofing layer on old flat roofs

Application Steps

1/ Existing — Left in Place

BITUMINOUS PAINT · BITUMEN EMULSION · BITUMEN FELT - The existing bitumen substrate stays in place. No stripping. No breaking up. No disposal costs. No unnecessary disruption to the building or its occupants.

BITUMEN SURFACE — CLEANED & PREPARED - All loose, delaminated and blistered bitumen material removed. The remaining surface must be sound and free from debris, ponding water and any contamination that would prevent adhesion.

2/ UltraBond WP

PRIME - Applied over the cleaned bitumen surface before any other product is installed. UltraBond WP seals the bitumen — preventing wet or playable bitumen from off-gassing through the system above it, which would cause system failure and delamination. It also creates a stable cementitious bonding layer with extreme adhesion that the ArmTec system bonds to directly. Do not skip this step

3/ ARMTEC MESH

REINFORCE - Fibreglass reinforcing mesh rolled out and shaped across the full surface — distributes stress, bridges surface irregularities and absorbs any ongoing movement in the substrate below.

4/ HyperFlex

BOND MESH TO SURFACE - Applied over the mesh and pressed firmly through to bond it directly to the UltraBond WP primed surface below — locking the reinforcing layer permanently in place.

5/ HydroSeal HF

WATERPROOF - 2 X COATS - First coat of seamless liquid rubber membrane applied across the entire system once touch dry and walkable. The final coat completes the seamless waterproof barrier — UV stable, fully bonded, available in 15 colours. Once cured, the roof is permanently waterproofed.

HOW IT WORKS

WHY COLD-APPLIED BITUMEN FAILS — AND HOW TO STOP IT FOR GOOD.

Cold-applied bitumen waterproofing — bituminous paint, bitumen emulsion and bitumen felt — has a fundamental design limitation: it is a surface coating applied to the top of the substrate rather than a fully bonded membrane integrated into it. Over time, UV exposure oxidises and hardens the bitumen, thermal cycling opens cracks, and moisture works its way through every blister and split. The system that was supposed to keep water out starts absorbing it instead.

The ArmTec HyperFlex system solves this by first sealing the bitumen with UltraBond WP — preventing any off-gassing from wet or playable bitumen that could cause the system to fail or delaminate. UltraBond WP is an essential first step on any bitumen substrate. Once the bitumen is sealed, the ArmTec Mesh is embedded with HyperFlex, and all outlets and corners are reinforced with StretchSeal Membrane and HydroSeal HF — creating a watertight seal at every termination point without heat or open flame.

The waterproofing system is a high-performance universal waterproofing system specifically developed for long term protection. Applying the SealPro waterproofing system will guarantee a seamless waterproofing system that is UV resistant and durable.

Balcony Waterproofing

Balconies, like all other parts of a property, require waterproofing. Whether the balcony is constructed using a concrete slab or timber, if water has penetrated the top surface, it will find or cause weakness. This will result in water damage to the ceiling or walls below. The solution to this problem is to waterproof the balcony. Explore the Armtec under-tile waterproofing systems for more information.

Tile Roof Waterproofing

The tile roof waterproofing system is used to waterproof roof ridge, valley, flashing & parapet walls. The system will seal your roof and help protect against leaks and weathering. The tile roof waterproofing system is UV stable, weather-resistant, durable, long-lasting and low maintenance.

Metal Roof Waterproofing

Our approach to restoring and waterproofing metal roofs offers a long-term solution, with no exposure of brittle materials to the elements, providing you with a leak-free roof for years to come. The waterproofing system can be used to seal ridges, valleys, joints, overlaps & screwlines.

Ponds, Dams & Reservoirs

The waterproofing system can be used to seal ponds, cement dams, water features, birdbaths and fountains. When fully cured the waterproofing system forms an impervious, flexible and aesthetically pleasing waterproofing membrane which enhances the look of the pond or water feature.
