GRP LINERS – COVER SLAB – SEALING PLATE & PRE-FABRICATE BENCHING

GRP LINERS

Goodwin’s Anti-corrosive GRP liners offer a robust, durable, and cost-effective solution for protecting the internal surfaces of concrete manholes. By preventing corrosion and extending the life of these critical components, GRP liners help maintain the integrity and efficiency of sewage systems, ultimately contributing to more reliable and sustainable wastewater management.

 

The manufacturing for the prefabricated anti-corrosive sewage manhole’s GRP Liners & accessories for Shallow manholes, Deep manholes & Very-deep manholes. Type-1(Straight type), Type-2(Reducer type), and Type-3(Liner with landing platform) are suitable to fix with sewerage manholes, pumping stations & wet wells. Also, we can be custom-designed as per client requirements. All manufactured GRP Liners shall have GRP ties on the external surface at 500mm center to center to bond with concrete.

 

The anti-corrosive GRP Liners and accessories shall have approximately 90% Vinyl ester resin in combination with C glass tissue mats (surface veil) for the internal surface. The structural layers shall have approximately 65% - 70% is Vinyl ester resin in combination with chopped strand mat (ECR glass in liner). The external surface should have 2400tex direct roving to keep stability and required stiffness. GRP Liners & Accessories play the role of preventing corrosion and abrasion effects that can degrade and eventually destroy the filling concrete. All these products are simply 6mm thick.

COVER SLABS

GRP Cover Slabs are increasingly used for protecting sewer and sewerage manholes due to their numerous advantages over traditional materials like concrete. GRP Cover slabs offer a modern, efficient, and sustainable solution for protecting sewer and sewerage manholes. By incorporating GRP cover slabs, municipalities and infrastructure developers can enhance the performance and longevity of their sewer systems while minimizing maintenance costs and environmental impact.

GRP PREFABRICATED BENCHING

GRP Prefabricated Benching sewer manholes with a non-slip surface, when incorporated with concrete foundation slabs, provide an innovative and effective solution for modern sewer systems. The non-slip surfaces, when used in conjunction with concrete foundation slabs, offer a robust, durable, and safe solution for modern sewer systems. The combination of materials leverages the strengths of both GRP and concrete. The robust concrete foundation ensures that the manhole remains securely in place, reducing the risk of displacement or collapse.

GRP SEALING PLATES

GRP sealing plates with EPDM rubber gaskets offer a reliable and effective solution for protecting groundwater from contamination and containing sewer gases within manholes. Their combined properties of durability, flexibility, and resistance to environmental factors make them well-suited for use in sewer infrastructure. These plates are typically designed to fit securely over the manhole opening, providing a strong barrier against external elements. The combination of GRP sealing plates and EPDM gaskets ensures a watertight seal around the manhole. The gaskets maintain their flexibility and sealing capabilities over a wide range of temperatures and conditions, ensuring long-term protection against groundwater ingress. This prevents groundwater from entering the sewer system, which can cause overloading and potential contamination. The Rubber Gasket provides an airtight seal that prevents sewer gases from escaping the manhole. This is crucial for maintaining air quality and preventing Odors in surrounding areas.

BENIFITS

GRP Liners & accessories are an advanced solution for protecting the internal surfaces of concrete manholes from corrosion and other forms of degradation. These are offer several benefits, making them an ideal choice for enhancing the longevity and performance of sewer infrastructure.

Durability, Longevity and Strenght.

GRP is highly resistant to corrosion caused by chemicals, sewage gases, and environmental factors, making it ideal for harsh sewer environments and ensuring a Significantly increases long lifespan. The combination of a strong GRP body and a stable concrete surface enhances the overall durability and performance of the manhole system.

High Strength-to-Weight Ratio.

Despite being lightweight, offer high strength, ensuring they can withstand heavy loads and traffic without damage and are resistant to abrasion and physical wear.

Ease of Installation.

Quick and efficient installation compared to traditional methods. Minimizes disruption to existing infrastructure and reduces downtime.

Enhanced Flow of Eficiency.

Smooth interior surface improves hydraulic performance by reducing friction. Reduces the likelihood of blockages and sediment buildup.

Industrial and Muncipal Use.

Suitable for both industrial effluent and municipal wastewater systems. Effective in environments with high chemical exposure.
