Basement Lowering Job in Pickering ON

RCC can lower your existing basement to provide you with valuable living space. RCC uses two types of systems, the benching system, and the underpinning system. When benching a basement, concrete is poured in front of the existing foundation to add structural support. The existing basement floor slab is broken and the soil underneath is excavated to allow extra ceiling height. Gravel is added as a sub-slab drainage layer to reduce any future water problems that could be caused by a rising water table pushing up through your new concrete floor. The new concrete slab is then poured. Benching can be a cost-effective way to add height to your basement, but the concrete benches that are poured as the structural supports can take up quite a bit of floor area. Underpinning is similar to benching, but this process requires structural support to be placed directly beneath the footings of the house, essentially extending the footings. The original floor is broken, and the soil underneath is excavated and removed. Pockets of soil from underneath the footing are removed and replaced with concrete. Then gravel is added as subsurface drainage, like the benching system, and the finished concrete floor is laid on top. This system will maximize floor space and create height in the basement.
