Accurate enclosure positioning in pre-cast concrete projects
02 May 2023
When building with pre-cast concrete walls and floors, it’s vital that enclosures used to house electrical sockets and devices remain in place during the concrete pour. Movement of the enclosure during this phase can result in installation challenges or wastage of an entire pre-cast wall.

Precast Concrete Structures, which specialises in large building projects, has worked with Spelsberg UK for over 10 years, to achieve reliability for enclosure placement.
Concrete is widely used as a preferred material for large buildings, for its durability and speed of construction. Build speed and ease are often enhanced if sections can be pre-cast and delivered for on-site assembly.
Precast Concrete Structures designs, supplies and installs frames comprising pre-cast concrete walls, floors and staircases, for projects across the UK. This includes buildings such as hotels, student accommodation, and prisons.
When walls and floors are installed, they’re ready for electrical contractors to fit cabling and devices. This means that enclosures required to house electrical connections, communications cables and devices need to be installed at the same time as the concrete walls are cast.
During the cast, pouring tonnes of concrete from heights of 2m presents a challenge for securing the position of the enclosures that can easily move under the flow of the wet concrete.
