Underground Drainage Pipes

Ashirvad offers an industry leading range of underground and surface drainage systems. Underground drainage pipes can be used in various constructions such as solid wall and structured wall. Being 100% watertight, it is free from ingress and seepage of water and hence considered to be most hygienic. Unlike conventional drainage products, it is free from pollution of underground water, soil or ill effects on building foundations. They are suitable for all types of commercial and domestic installations. Ashirvad Underground Drainage system is intended to carry soil, waste, rainwater or industrial effluents from building to roadside sewers or drains and from there to waste treatment plant or point of discharge. Ashirvad Underground Pipes are produced in 3 layers with the middle layer comprised of PVC foam to reduce both noise and weight.

Design features

Wide range of pipes and fittings

This systems offers unparalleled installation options with high quality finish, superior dimensional accuracy and stability. Ashirvad underground drainage pipes are available in 110 mm to 315 mm dia with different stiffness classes mainly categorised as SN2, SN4 and SN8: 110 mm with stiffness class SN4 and SN8, 160 mm, 200 mm, 250 mm and 315 mm with stiffness class SN2, SN4 and SN8.

Under technical collaboration from REDI*

Ashirvad under technical collaboration from REDI made it possible to have wide range of products in underground drainage range. Special fittings such as non return valves, easy clips, mechanical saddles, swivel and surface drainage are imported from REDI. REDI (Italy) is active since 1960 and are leaders in the management of waste water system as well as ventilation in Europe.

Fully analyzed raw materials

The raw materials used for manufacturing the products are fully analyzed and procured with utmost care to deliver high quality products to the customers. uPVC is a versatile plastic material that has been used for plumbing and drainage systems for many decades. Ease of processing, smooth interiors as well as rigid pipes and fittings that can be manufactured with uPVC have been instrumental in its widespread usage for such applications.

Best manufacturing standards

The pipes are extruded on state-of-the-art extruders and are socketed on on-line belling machines. The fittings are manufactured in collapsible core moulds to ensure straight sharp finish of the grooves for higher dimensional accuracy of the product which finally ensures the highest degree of dimensional accuracy and product strength.

Underground Foam Core

Lightweight and High impact strength

The underground pipes, also known as foam core pipes, are multilayer pipes that have outer and inner layers of conventional PVC and a middle layer of foamed PVC. The Outer and inner layers are designed to take the external load and the middle layer of foamed PVC gives rigidity to the product. It also maintains the shape of the pipe under load. The Foam core technology reduces the total weight of the pipe and makes it lighter when compared to the single solid wall PVC pipes.

Leak proof joints

The fittings are manufactured in collapsible core moulds to ensure straight sharp finish of the grooves for higher dimensional accuracy of the product which finally ensures the highest degree of dimensional accuracy and product strength.
Ashirvad underground drainage systems, therefore, offer unparalleled strength and product finish that provides a leak proof, maintenance free and long lasting solution to the customer.

Why only Ringfit?

New moulding technology has made it feasible to produce bi-moulded rubber rings that are more dependable and do not slip out of the groove during installation. This requires no threading or solvent cementing. The spigot end is held firmly in the socket with the help of the Brown Seal™. It ensures a leak proof joint and can withstand high pressure flow. This system is made in high tech, new generation machines and offers unparalleled performance, strength and finish.

Wide temperature range

Ashirvad underground drainage systems are self-extinguishing and do not support combustion. uPVC must be forced to burn due to its high Oxygen Index (LOI) of 45. LOI is the percentage of oxygen needed in an atmosphere to support combustion. uPVC has a coefficient of expansion of approximately 0.06mm/m/°C. Consequently a 2m length of soil or waste pipe will expand by 2.4 mm for a 20°C rise in temperature. This expansion is taken into consideration in the design of systems and components, and must be accommodated when installing.
