Fully inground weighbridges provide a completely level weighing surface with the surrounding ground level. Access to the load cells must be made either by including access holes in the deck or to the side of the deck as part of the foundation design. Since vehicular traffic often travels adjacent to the deck, the access hole covers are designed and constructed to take the expected vehicle loadings.
Drainage must be considered, either as a sump or as a drainage pipe, and must be located where most effective and appropriate for the site. Fully inground weighbridges claim the least surface area of a site than any other weighbridge type. However, they are the most expensive weighbridge type to construct due to the extensive excavation work required and slightly more concrete and reinforcing required.
