Skilled Tradesman
More & more skilled building tradesman and paving contractors are finding that using Gapfast has rapidly increased the speed of installing paving and ensuring a perfect finish:
- Saves time – saves money
- Gapfast stay locked in place – adds to the structural integrity of the paving
- If the pointing medium fails (as if often the case) – Gapfast won’t
- Natural stone (such as Indian Sandstone) – maintains a minimum 10mm joint even were edges are uneven
- Decorative / birds beak pointing – our video shows how Gapfast can maintain a minimum 20mm joint
Commercial User
When installing paving Gapfast will add significantly to the structural integrity of the specified design. By using Gapfast the landscape architect/civil engineer does not have to rely alone on the horizontal bond strength between the paving unit and the bedding mortar. Similarly little requirement is placed on the pointing medium itself (which frequently fails). A flagged paving system incorporating Gapfast will allow the entire paved area to act almost as a monolithic (but flexible) construction.
The horizontal loads placed by vehicular braking and acceleration forces are considerable, similarly rotational loading brought about by power steering of stationary commercial vehicles is again significant. By using Gapfast, these stresses are distributed throughout the entire paved area, rather than relying on the individual paving slabs.

I like the straight lines/same size gaps that we have achieved by using your product (helps with the OCD!), can not believe the idea is not ‘well known’ within B&Q, Homebase….”
