What are strip foundations used for?

Strip foundations (or strip footings) are a type of shallow foundation that are used to provide a continuous, level (or sometimes stepped) strip of support to a linear structure such as a wall or closely-spaced rows of columns built centrally above them.

Where are deep strip foundations used?

Deep strip or trench foundations are similar to strip foundations and are used in low rise domestic construction such as building houses, house extensions. Deep strip or trench foundation is used when soil is not strong enough for a generally strip foundation.

What are strip footings?

A Strip Footing is a relatively small strip of concrete placed into a trench and reinforced with steel. The footing supports the load of the exterior walls and any interior wall that is load bearing or supports a slab such as for a bathroom. Strip footings can be used for both traditional timber and concrete floors.

What is the difference between strip and trench foundations?

Usually wider, strip foundations use less concrete than trench fill because the base layer of concrete is thinner. Strip foundations are often necessary in softer soils, such as sand, since they spread the load of the building out over a greater area.

What is the difference between strip and raft foundations?

Strip foundation is used to support a line of loads such as load-bearing walls. Raft foundation consists of a concrete slab which extends over the entire loaded area so that loads from entire structure are spread over a large area leading to a reduction of the stress of foundation soils is reduced.

What is the minimum depth of a strip foundation?

Deep Strip Foundations A concrete strip, sometimes reinforced with steel mesh, supports the walls. The trench depth is variable but in most cases should be at least 1m with a width of 600mm. The concrete should have a minimum depth of 225mm.

What is stripping of site?

STRIPPING. Strip topsoil only from those areas that will be disturbed by excavation, filling, road building, or compaction by equipment.

What is concrete stripping?

The removal of concrete formwork also called as strike-off or stripping of formwork should be carried out only after the time when concrete has gained sufficient strength, at least twice the stress to which the concrete may be subjected to when the formworks are removed.

What is strip footings in construction?

Is Strip foundation expensive?

Deep Strip foundations are the least expensive and are used when ground conditions are good. A concrete strip, sometimes reinforced with steel mesh, supports the walls. The trench depth is variable but in most cases should be at least 1m with a width of 600mm.

What buildings use strip foundations?

Strip Foundations They are generally used for ground where the subsoil is of a good bearing capacity. Strip foundations are designed for structures where the load is relatively modest, such as, low-to-medium rise domestic buildings.
