MORE INFORMATION
A simple road crossing can be installed and backfilled in one day. These box culverts can also be installed in virtually any weather condition. Concast manufactures box culverts in accordance with the industry’s highest quality standards. The box culverts can be produced either by the efficient dry cast concrete process, or the versatile wet cast concrete process. Precast sections are also available as an open footing culvert, also known as a 3-sided box or Tri-Span.
Dry cast concrete box culverts are available in the 9 standard sizes listed in OPSS 1821, Table 1. All 9 sizes are supplied with a single offset joint and a pre-lubricated rubber gasket.
Wet cast concrete box culverts are available in hundreds of span, rise & wall thickness combinations to suit any application. Each precast section can be supplied with a shiplap joint to be filled with a mastic or mortar.
The standard lay length for all box sizes is 2.44m. Longer or shorter lengths are available to meet design and logistics limitations, and project requirements.
