Majority of buildings

Continuous strip

Reinforced concrete

Rests on the soil

Depth and Width

Soil type and

building load

Strip Foundation

Department of Design & Manufacturing Technology

WT5912

Traditional Strip foundation

Most commonly used

Usual 1050 X 350mm

Suitable for

Average Good bearing

capacity soils

Not suitable for

Very soft clays

Silt

Peat

Badly made up - ground

Strip Foundation

Department of Design & Manufacturing Technology

WT5912

Stepped Strip foundation

Sloping sites

Reduce excavation

Step depths

112mm or 225mm

Overlap of concrete

Minimum 300mm

Not less than depth

of concrete foundation

Strip Foundation

Department of Design & Manufacturing Technology

WT5912

Wide Strip foundation

Not common

Reinforced

Transverse reinforcement

Resist tensions

Wider than 900mm

Suitable for

Ground with low bearing capacity

Expensive

Strip Foundation

Department of Design & Manufacturing Technology

WT5912

Deep Strip foundation

Rests on suitable strata

Excavate 900mm or more

Trench filled within 150mm

of ground level

Width depends on depth

Deep Foundation

Department of Design & Manufacturing Technology

WT5912

Raft foundation

Suitable for

Low load bearing soils

Soft natural ground

Very soft clays

Silt

Peat

Made up ground

Average Good bearing capacity soils instead of strip foundations

Raft Foundation
