Durodrain & Superswan
The complete Durodrain and Superswan 110mm to 250mm underground range — solid wall and structured wall pipes, sockets, bends, junctions, gullies and access fittings for every below-ground waste connection.
The essentials for installing Durodrain and Superswan pipe and fittings, drawn from our full sewer & drain design manual.
01
Cross-cut saw or angle grinder, then chamfer the end to 15° and at least 50% through the wall thickness.
02
Keep the rubber ring free of grit and mud — pipe ends often pick up sand accidentally on site.
03
Apply liberally, avoiding the seal housing. Smooth away any lumps of gel lubricant with a wet rag.
04
Insert fully into the socket in one motion. On large pipes, avoid excessive force near full insertion.
05
Minimum 100mm compacted granular bed. Minimum cover of 900mm for sewers, 300mm for drains.
06
Leave joints exposed and air-test (manometer test) each section before covering.
07
Compact in 300mm layers to 90% modified AASHTO density — tighter under roads and trafficked areas.
Up to 2° of deflection is absorbed through each socket. For larger changes in direction, use a Durodrain bend fitting rather than forcing the joint.
Store pipes flat, off the ground on timber supports, covered from direct sunlight, and stacked no higher than 1.5m.
Load with sockets and spigots alternating, larger pipes at the bottom, and secure the load without overhang beyond 1m.

Straight answers about this range's specs, certification and applications.
Durodrain is Swan Plastics' uPVC pipe and fittings range for below-ground drainage, connecting waste from buildings to municipal sewer or septic systems.
Durodrain is certified to two separate SABS standards — SANS 791 for solid wall pipe and fittings, and SANS 1601 for structured wall pipe.
Both. Durodrain covers our solid wall uPVC pipe as well as structured wall pipe, each certified to its own SANS standard.
Socketed Durodrain pipe is available in Class 51 and Class 34 HD (heavy duty) across seven size variants, plus plain end pipe in CU110/6 and CU160/6.
Superswan is Swan Plastics' uPVC structured wall pipe for underground drainage, certified to SANS 1601 and available from Ø110mm to Ø250mm in 100kPa, 200kPa (medium duty) and 400kPa (heavy duty) stiffness classes, as socketed or plain ended 6m lengths. It sits alongside Durodrain in our underground range and connects with Durodrain fittings.
Durodrain pipe and fittings range from Ø110mm to Ø250mm.
