Pile joints can be used with both precast and prestressed concrete piles. Examples include curtain walls and precast concrete walls. A wooden frame designed bungalow, over clad with precast concrete panels. The tunnels are lined with precast concrete liner segments. To speed construction, the elevated trackway is built using precast concrete box girder bridge segments. The following is a sampling of the numerous products that utilize precast/prestressed concrete. The IMT structure consists of eight precast concrete units. Multi-storey car parks are commonly constructed using precast concrete. The use of precast concrete panels for floor and wall construction has also increased. Stormwater drainage, water and sewage pipes, and tunnels make use of precast concrete units. Precast concrete is nontoxic and environmentally safe. The bridge was constructed as four arches, each made from precast concrete box sections. Using a precast concrete system offers many potential advantages over onsite casting. The base of the building is made of granite and precast concrete. It usually consists of precast concrete segments which form rings.
