What is a strip foundation?
Strip foundations consist of a continuous strip of concrete formed centrally under loadbearing walls. The continuous strip acts as support for which walls are built and is to a width to spread the load evenly of the building on the ground underneath it, supporting it.
What material is a strip foundation?
concrete
Strip foundations consist of a continuous strip, usually of concrete, formed centrally under load bearing walls.
What is the minimum depth of a strip foundation?
150mm to 500mm thick
Strip foundations should be 150mm to 500mm thick. Trench fill foundations should be greater than 500mm thick.
Why is strip foundation good?
Foundations provide support for structures, transferring their load to layers of soil or rock that have sufficient bearing capacity and suitable settlement characteristics.
When would you use a strip foundation?
A strip footing is used for load-bearing walls including footings for extensions and conservatories and house foundations. They are also used to accommodate a row of closely-spaced columns. The wider base of this foundation type spreads the weight over a wider area and provides better stability.
Why are strip foundation used?
Strip footing is commonly used as foundations for load-bearing walls; and when the soil has good bearing capacity. It is preferred for low rise to medium-rise residential buildings. Here a strip of concrete runs below the entire length of the wall, thereby distributing the load from the walls to the ground.
Does strip footing need formwork?
require simple formwork (no edge rebates) require simple excavation that is exposed for minimal time.
How wide should strip footings be?
Very broadly, the size and position of strip foundations is typically related to the wall’s overall width. The depth of a traditional strip foundation is generally equal to or greater than the overall wall width, and the foundation width is generally three times the width of the supported wall.
How wide should a strip foundation be?
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 is the difference between strip and pad foundation?
Pad foundation refers to the foundation which is intended for sustaining concentrated loads from a single point load such as structural columns. Strip foundation is used to support a line of loads such as load-bearing walls.
What is the disadvantage of strip foundation?

In fact, the quality of your home heavily relies on the right foundations and, without correct planning and construction, there may be very serious and dangerous consequences.
What is a strip foundation used for?
Strip foundations are one of the most commonly used 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.
What is a normal strip foundation?
