Under Reamed Piles in Kenya, Uganda, Tanzania, Rwanda, Somalia, Sudan, DRC Congo, Mozambique, Zambia, and the rest of the East African region.
Under reamed piles are a type of foundation used in construction to provide structural support for buildings, bridges, and other types of infrastructure. These piles are typically used in areas where the soil is weak or unstable, and traditional shallow foundations are not adequate to support the weight of the structure.
Under reamed piles consist of a vertical shaft or stem, which is typically made of reinforced concrete, that is inserted into the ground. The lower portion of the shaft is then widened or flared out into a bulb-like shape, which is called the under ream. The under ream provides additional surface area and bearing capacity, which helps to distribute the load of the structure more effectively.
The under reams can be created using a variety of methods, including mechanical digging, drilling, and pressure grouting. The size and shape of the under ream depend on the specific soil conditions and the weight of the structure to be supported.
Under-reamed piles are often used in areas where the soil is expansive or subject to settlement, as they can help to resist these forces and prevent damage to the structure. They are also used in earthquake-prone areas, as the wide base of the under ream can help to absorb and distribute the energy of seismic waves.
Overall, under-reamed piles are a reliable and effective type of foundation that can provide strong structural support in a variety of soil conditions.
