One of our registered contractors, WJ Roofing recently undertook this small flat roof refurbishment in Lurgan. The roof had deteriorated and needed a deck replacement, followed by water proofing. The client opted to go with our Hyperdesmo Liquid Waterproofing system due to the benefit it offered over traditional systems.
The roof was long overdue a replacement. The contractor completely removed the existing membrane and deck.
Fall direction changed to prevent a build up of water on the neighboring flat roof.
The tongue and grove deck was selected to ensure joint movement was minimised. The joints were sealed using Hyperseal Expert 150 to further strengthen the joint and provide an additional waterproof barrier.
The roof was primed using Geodesmo 50 primer. The primer was selected as it offered excellent adhesion, while maintaining a quick curing time of 2-3 hours. Geodesmo is highly versatile a single component primer, ideal for priming porous and non-porous substrates.
Hyperdesmo Particular was selected to reinforce the joints further, and also to seal around the screws fixing the deck down. Particular is a fiber reinforced polyurethane membrane, it can be applied on a vertical plane without any adhesion issues. It is ideal for upstands, and for strengthening any joints. Once cured, it forms a strong, fully flexible polyurethane membrane.
Hyperdesmo HAA was chosen as he main waterpoofing layer. HAA is a single component liquid polyurethane membrane, it offers many benefits including:
- Single component – no mixing required
- Fast curing without the need to measure accelerator
- Can be applied in a single layer
- Cures to form a fully flexible membrane
