New ASA Manhole & Hydrobrake Penstocks

Althon has a new range of ASA Manhole & Hydrobrake Penstocks which have been designed for use in manhole chambers and hyrdobrake chambers. Our Hydrobrake penstocks are suitable for use with pipework up to 300mm and have a design life of 50 years at 1Mwc and 72 hours at 5Mwc. Typically the contractor will create a flat surface within the manhole chamber to fix the penstock to. The smoother the surface finish of the concrete the better the seal will be between the penstock and the wall. We provide all required fixing bolts, chemical anchors and an EPDM seal with every penstock.
