Bored Cast-in-Situ piles (BCIS) in Kenya, Uganda, Tanzania, Rwanda, Somalia, Sudan, DRC Congo, Mozambique, Zambia, and the rest of the East African region.
Bored Cast-in-Situ piles (BCIS) are a type of deep foundation where a hole is drilled into the ground, and then the hole is filled with concrete and reinforced with steel. These piles are typically used to support heavy structures or to transfer loads of a structure to deeper, more stable layers of soil. They are called "bored" because the hole is drilled using a drilling rig, and "cast-in-situ" because the concrete is cast or poured into the hole at the construction site.
- Foundation support for high-rise buildings, bridges, and other heavy structures.
- Retaining wall construction.
- Seismic retrofitting and strengthening of existing structures.
- Ground improvement and stabilization.
- Construction of deep basements and underground structures.
- Environmental protection, such as controlling subsurface contamination.
- Installation of deep well foundations for offshore structures, such as oil rigs.
BCIS piles are preferred in situations where the soil is soft or unstable, and shallow foundations are not sufficient to support the structure's loads. They are also suitable in areas where there are restrictions on the use of heavy construction equipment, as they can be installed using smaller, more maneuverable drilling rigs.
