CASE STUDY: Service station and convenience store

Service StationTo avoid closure of a busy service station and convenience store due to severe water ingress, CTF were invited to design a solution to eliminate a troublesome narrow central gutter, which had been continually leaking for many years.

We suggested eliminating the central gutter with new falls formed in the insulation to drain the roof to an external gutter to the rear of the building.

Site levels were taken to establish the existing roof falls.

A tapered insulation system in a single layer was manufactured to overcome the back falls, together with special gutter infills.
