HEADWALL 300MM PIPE TWIN CELL 300MM SPACING CIVILMART HW2-P-0300-3SP at a glance

The standard range of Twin Cell Pipe Headwalls suit reinforced concrete pipes from 225mm to 1500mm diameter.

Triple and quadruple cell headwalls are also available for additional pipes.

The design conforms to state and council requirements, ensuring high-quality products and peace of mind knowing your project will stand the test of time.

Measure your poly pipe inner diameter in imperial sizing (3/4", 1", 1.25", 1.5", or 2") to ensure correct fitting selection. For barb fittings, slide the pipe onto the barb and secure with two stainless steel clamps positioned either side of the barb ridges, tightening firmly to create a watertight seal. For solvent weld fittings, clean both surfaces, apply solvent cement to the fitting socket and pipe end, then insert quickly and hold for 30 seconds. Allow 24 hours cure time before pressurising the system. Tips: Always use stainless steel hose clamps with barb fittings in rural Queensland systems to prevent corrosion and ensure long-term reliability. Check that your poly pipe is rated to 800kPa (standard green stripe) and verify the fitting matches this pressure rating for your application, whether gravity-fed or pump-driven.
