SEWAGE LINERS

The manhole liners are produced using the Filament Winding process which enables us to achieve excellent mechanical properties such as superior tensile strength and modulus, as well as flexural and lap shear strength. The filament winding process also allows precise positioning of glass fibre in both the circumferential and longitudinal directions. GRP Liners prevent the corrosion and deterioration of manholes in aggressive environments. Anchoring lugs are attached to the external surface to ensure proper adhesion to concrete once it is has been casted and set.
