Bruno Altin & Co:

Pre-cast concrete pipe ends and headwalls from Bruno Altin & Co are available in a wide range of sizes and are manufactured to fit pipes from 10cm x 1.8m internal diameter.

Headwall styles include:
  • PIPE ENDS/HEADWALLS take a steel or aluminium door and are available with full neoprene to give water tight seal.
  • STEP HEADWALLS where the space between the board facility and the end of the pipe has been extended allowing for overflow control.
  • PLAIN PIPE ENDS can also be used to keep the soil back and minimise erosion. These are often used in access crossings, subdivisions & road works.
  • NIBS/DROP SILLS Are available in half or full height. They can be used to reduce silt build-up in pipes, increasing water flow rates.

Custom headwalls can be manufactured to order for special requirements where a higher than standard Pipe End/Headwall is necessary, such as drainage/supply under an existing channel. Current sizes range from 40cm to 3m in height.
