Level Invert on Headwalls

The photo above is one of our smaller RSFA headwalls (RSFA18B 01 1150) showing a great example of when a customer requires the pipe ID at level invert. We cast in a slightly larger opening than the OD of the pipe to make installation easier on site, once the pipe is in the correct position site will fill the void around the pipe with high strength non shrink grout. The SFA1 Outfall Safety Grille is fitted to the headwall 150mm up from the spillway as standard when the pipe ID is level with the spillway.

Bespoke Angled Rectangular Headwall

Here at Althon we have 100’s of different precast concrete headwall options to suit a wide range of pipe sizes and materials. However sometimes you still cannot find the one you need to suit your site requirements, so we are always happy to look at designing a bespoke option for you.

Our latest bespoke headwall being cast in the factory is an angled rectangular headwall factory fitted with pedestrian guardrail, slides for aluminium stop logs and a fixed grating for a box culvert opening. This design suits the clients site requirements and having the accessories factory fitted to a precast concrete structure saves time on site and has great health and safety benefits.

Arbroath Flood Prevention Scheme

Althon have recently supplied several precast concrete headwalls as part of the Arbroath Flood Prevention Scheme. In the images below you can see our SP15J headwall then either side of the channel our AH12CB LH and RH precast concrete headwalls and then our smaller AH4CB LH and RH headwalls.

The scheme is designed to reduce the risk of flooding from the Brothock Water, which runs through the coastal town, and provide a one in 200 year standard of protection. The scheme is focused on holding back water flow in the catchment above Arboath and then reduce flow in Brothock Water thus protecting parts of the town that have suffered previous flooding and still remain a flood risk.
