This concrete top section is designed for use with metal cover and frame assemblies in domestic drainage systems. Measuring 600 x 450 x 60mm and weighing 42kg, it offers a sturdy solution for completing inspection chambers and manhole installations.
On site, the unit is typically positioned as the upper component above a precast chamber, providing a stable surface for fitting metal lids and frames. It can be quickly jointed using bituminous or butyl compounds, ensuring a watertight seal and minimising installation time.
