Greyton was engaged on this project to provide a 2 hour Hydrocarbon fire rating to the 2000m2 concrete cut and cover slab on the East and West bound lanes of the new M4 motorway near the Homebush tunnel entry/exit. This was a Promat Tunnel specification using the Fendolite 2 cement based vermiculite spray product 65mm thick applied in two coats, and a specially sourced stainless steel mesh, fixed to the concrete with stainless steel anchors.
