What is Cut and Cover?
Cut and cover is the method of digging a large open pit to create the basement walls and floor slab from below grade. After the structural skin is finished, dirt is backfilled into the basement, and construction or renovation of a building can begin. There is great access for construction with this approach, and it can be cost-effective on the right job site.
When Cut and Cover Is Used

Work on the Site and Excavation The first step is to prepare the land in which the road will be developed. The ground is dug out to the depths of the proposed basement with stable side walls or shoring provided. The foundation is cast in place and the base slab consists of a reinforced concrete lid. Basement walls can be reinforced concrete or masonry, both according to design. Once the building envelope is closed, various weathering systems sub-systems must be applied to prevent water infiltration. Ultimately, the disturbed earth is replaced around the structure and the surface above it restored.
Waterproofing and Drainage Considerations
It is necessary to ensure a correct watertightness for the cut and cover method. Foundation wall waterproofing is achieved by the use of an exterior damp-proof coating or membrane which can be supplemented with the installation of a perimeter drain system to direct groundwater away from the foundation. These initiatives prevent long term damage and meet you with UK building regulations.
Benefits of Cut and Cover Method

It is generally less expensive than more complex underpinning techniques, and allows a basement to be constructed cost effectively even when the design calls for a deep one.
