Commercial Flat Roofing IKO 25 Year For Tyne Tunnel

Commercial Flat Roofing – What we did:

When we originally surveyed this Commercial Flat Roofing project we took core samples to ascertain the existing build up. We found the roof to be dry underneath. This finding allows us to leave the existing insulation and waterproof covering in place only having to strip off all gravel to area and stripping out all detail and any loose or blistered parts to the area.

We then supplied and fixed IKO Mach One single layer system to all existing area and IKO Goldseal to all detail i.e wall upstand and box gutter detail.

The skylights with being a round shape we decided the best solution would to be to coat these using IKO Polimar seamless liquid system rather than many flashing details eliminating the least possibilities of water ingress.

This commercial flat roof was approximately 900 square meters and took DVC Roofing 3 weeks to complete. All our guys on this job are all fully  approved IKO installers all holding relevant training certificates.

This roof has now been passed off by an IKO Technical engineer and will now hold a single point warranty from IKO PLC.

Mach One membranes are comprised of a polyester glass-fibre composite reinforcement with exceptional mechanical strength and stability. The reinforcement is coated with a high percentage SBS modified bitumen incorporating Graphite Firewall Technology, and surfaced with green, black or brown mineral granules.

Mach One is a single layer roofing system which can be mechanically fastened, ballasted or bonded with polyurethane adhesive. The membrane may be used on either insulated or uninsulated roofs in conjunction with the other IKO Systems products.
