Basement Foundation
This type of foundation provides a hollow substructure to allow space below ground level, primarily used for work or storage space.
Foundation Design
We provide foundation design for structures ranging from a small shed to a large industrial warehouse. Each foundation is designed around the structure, the project’s needs, the owner’s goals and the site’s soil conditions.
Foundation types we design
Caisson Foundation
This foundation is constructed by drilling a large hole in the soil, often down to a harder soil or rock, which is then filled with concrete. Sometimes, the base of the caisson will be bell-shaped to decrease contact pressure or soil pressure; these are considered belled caissons.
Pile Foundations
This foundation usually consists of long and slender members constructed by driving the members down to the correct foundation level. Sometimes this may be done by drilling tubes to the desired depth and then filling them with concrete before or during the removal of the tubes.
Strip Footing
Strip footing is also known as a continuous footing. This type of foundation consists of a row of columns in which each column is spaced near one another. Strip footing is a much more efficient and economical choice than a spread footing.
Spread or Isolated Footing
Spread or isolated footing, also known as a pad footing, is used when supporting an individual column. This type of footing can be designed as a rectangular slab of the same thickness, a square, or a circle. It may also have a step-like design to help distribute the load over a larger area.
Combined Footing
This type of footing is used when two columns are close together, and their individual footings would ultimately run into each other or cause an overlap.
Strap / Cantilever Footing
This type of footing consists of two individual footings connected by a structural strap. This allows the two bases to behave as one. The design can be more economical than a combined footing when the distance between columns is large and the soil pressure allows.
Mat or Raft Foundations
Also known as a slab foundation, this type of foundation exists under the majority of the structure, providing support.
