Utility Chambers

Rectangular utility chambers are produced using the same formwork as precast box units, so they are available in hundreds of inside dimension & wall thickness combinations to suit any application. The inside length and width dimensions of these chambers can be varied by 300mm increments and the wall thickness can be varied in 25mm increments to suit any depth and loading condition. Each precast section can be supplied with a single offset or shiplap joint to be filled with a gasket or mastic. The standard riser section heights are available in 300mm increments to a maximum of 2.4m.
