Precast concrete chamber with factory fitted penstock and actuator 

Althon precast concrete penstock manhole chambers are cast to order to suit any pipe openings and invert levels required. The benefit of using one of our concrete penstock manhole chambers is that we factory fit accessories to the unit prior to delivery to site. We can factory fit the penstock and actuator instead of manually using a spindle and T-Key if required.

Headwalls with Tideflex Valves 

Althon can manufacture concrete headwalls with Tideflex duckbill valves. We factory fit the duckbill valves to our precast concrete headwalls ensuring they fit properly and reducing installation time on site. Factory fitting duckbill valves to headwalls also means the headwalls do not have to be drilled on site which has great health and safety benefits.

New Precast Concrete N Headwall Range 

Althon have a new range of precast concrete headwalls that have been designed to suit steep banks or site conditions that have little depth from back to front for installation.

Our new N range of headwalls are manufactured to the same standards as our Sewers for Adoption headwalls and can be used on Section 104 Agreements where the sewers are to be adopted by the local water company.

We cast the opening in the back wall to suit the pipe diameter and material of the pipe being used. We can cast multiple pipe openings, elliptical, square or rectangular culvert openings into any of our headwalls. We can also cast pipe openings into the wing walls.
