Glass Reinforced Pipe is a structural liner for large diameter stormwater and wastewater systems. It can be customized designed to fit any shape size or form with 100 year design and service life. This product has decades of engineering and manufacturing design behind it along with dozens of certifications

Large diameter pipelines and culverts represent the backbone of any city’s utility network for the collection and disposal of sewerage and effective drainage of storm-water. In many cases the fabric of these pipelines, which may consist of brick, stone, concrete or clayware will have been constructed decades ago and although proven resilient, has eventually succumbed to the ravages of time, suffering the effects of H2S attack or erosion and may even be exhibiting signs of imminent failure due to structural loading beyond that of it’s remaining capability. At this point the need arises to consider the means by which the structural rehabilitation of these pipelines and ducts can be achieved whereby a new, 100-year plus life expectancy can be provided with a high degree of confidence. GRP structural lining solutions rehabilitate both circular and non-circular large diameter buried pipeline structures worldwide.

GRP Lining Panels are manufactured to fully comply with the WRc materials standards for GRP (Guidance noteWIS 4-34-02) and are also manufactured in accordance with BS5480, ASTM D3262 & ISO 16611:2017 Mechanical Properties At the outset of each project, a detailed design analysis is undertaken, taking into account all necessary criteria such as depth of pipe, condition of existing pipe, ground loading, the likely effect of external water etc. to determine the exact requirements for the liner design. Design work is generally undertaken in compliance with the requirements of the latest edition of theWRc manual (other standards may be used) which then establishes the liner thickness needed to produce a Type I, Type II or Type III liner (see Technical Section). This analysis takes into account the short and long-term mechanical properties such as: -   Flexural Modulus -   Bending Stress -   Tensile Stress Panels of any required liner type strength and stiffness can be produced using the sandwich construction method.
