HEADWALL SLOPING TO SUIT 375MM BLACK MAX CIVILMART HWLQLPSS3044C01 at a glance

Civilmart sloping headwalls are designed and manufactured to local council requirements.

Safe-Slope Headwalls provide a constant sloped front to permit the contact face to be blended into embankments.

This helps to protect vehicles and slashers from damage caused by falling into the space produced by the vertical face of standard Winged and Apron front Headwalls.

When packed and sealed with mortar or suitable compounds, this allows free draining in either direction.

Pipes with thinner walls than the design standard may be supported with mass concrete.

The connection into the socket should be sealed to prevent erosion of the back fill by storm water.

Identify your poly pipe size by measuring the inner diameter (typically 3/4", 1", 1.25", 1.5" or 2") — this determines the correct fitting size to purchase. Ensure the pipe end is clean and cut square before inserting into the barb fitting. Slide stainless steel hose clamps over the pipe, push firmly onto the barb until the pipe reaches the widest point, then tighten clamps securely on either side of the fitting. Check for leaks under pressure before burying or finalising installation. Tips: Always use stainless steel clamps with barb fittings to prevent rust staining and corrosion in Queensland's climate. For permanent installations, consider solvent weld fittings instead of barb — they eliminate the risk of slippage and are ideal for main supply lines under constant pressure. Route poly pipe away from direct UV exposure and secure it every 1–1.5 metres to prevent sagging and stress on fittings.
