Althon manufactures the largest range of precast concrete headwalls in the UK, catering to pipes, culverts, and box culverts. However, there are times when a bespoke solution is necessary, and we are equipped to deliver that as well.
Recently, we completed a project in Cumbria, where we designed a multiple piece headwall that includes a Kee Klamp handrail, multiple level grating, and stop logs. Prior to galvanizing, our factory assembles all components to ensure that once the headwall reaches the site, there are no fitting issues. This meticulous process guarantees a seamless installation and high-quality results.
