Relining with Tubus System is an established and proven technique for pipe renovation, or restoration, where several layers of a special corrosive-resistant glass flake reinforced polyester are applied to the inner walls of an existing pipe. This reinforced polyester dries to form a new, durable and seamless pipe system that has a life expectancy of at least 50 years. Tubus System relining is a cost effective and environmentally sustainable solution when renovating sewage pipe systems inside and outside buildings. Tubus System also carries out relining of tubular pipes and culverts for infrastructure and oil separators with minimum disturbance for the user and the surroundings.
