Increased Bearing Capacity

STRUCTURE & FOUNDATION "INCREASED BEARING CAPACITY"

Enhance soil bearing capacity for foundation support

When building on soft soils, the primary challenge is the soil's limited ability to support structural loads. BaseLok GeoGrid and GeoCell technologies distribute vertical loads over a much wider area, effectively increasing the bearing capacity of the underlying subgrade. This mechanical stabilization allows for the use of shallow foundations even in challenging soil conditions

How Increased Bearing Capacity is Achieved

Traditional foundation design often relies on the natural strength of the soil. When that strength is insufficient, standard practice involves over-excavation or deep foundations. BaseLok offers a more efficient alternative through the creation of a mechanically stabilized layer (MSL).

By incorporating BaseLok high-strength geogrids into the granular fill beneath a foundation, we create a composite structure with improved bearing capacity. This reinforcement system acts like a stiff platform, or "raft," that bridges across localized weak spots in the subgrade. As loads are applied, the geogrid interlocks with the aggregate, providing lateral confinement and preventing the outward movement of soil particles. This confinement increases the vertical stress the soil can withstand without failing.

For even more extreme loading or exceptionally weak soils, BaseLok GeoCell can be added for complete cellular confinement. This cellular confinement prevents the lateral displacement of infill material, allowing foundations to be safely constructed on soils with very low CBR values. The result is a significant increase in the factor of safety and a more reliable, predictable foundation behavior throughout the building's lifecycle.
