This is usually caused by shrinkage of the clay due to it becoming drier. Clay foundations can lead to cracked and damaged foundations and floors that become uneven.

Then you have to replace that with borrowed material. High plasticity clays have microscopic mineral grains that are especially attractive to water. Choosing the Right Foundation for Clay Soil. The basement would be 4 m deep or so below ground level so you are only talking of overexcavating 2 m or so - good insurance.

The strength and stability of soil depend on its physical properties. Each of them have numerous ways of achieving these fixes.

Submitted by David Edwards PhD on Thu, 06/17/2010 - 02:59. I intend to build an energy-efficient home capable of withstanding hurricane-force winds. With the use of NPA geocells, Stratum Logics are the experts in designing structures that conquer expansive clay conditions and other soft subgrades with swelling potential. What issues could this cause? My most recent foundation design on the stiff clay.

One of the reasons that raft foundations are used on clay soils is to reduce the soil contact area and concentrate the building loads on smaller areas of soil.

This is essentially a large concrete slab that is so thick that it can hold the mass of the entire house without flexing significantly, such the independent of the movement of the underlying soil, the base of the house is all on one flat, though not necessarily level, slab. Clay soil is unique and here you will learn its challenges, how to handle these challenges, and which foundations are going to work best. However, it is possible to build successfully and safely on expansive soils if moisture content can be reduced and stabilized against rapid fluctuation.

Slab-on-grade foundations are another good choice for clay soil. Why not run a settlement analysis and see if you need piled raft? Silt and Clay are considered to be smaller family members of soil group, Even small amounts of fines can have significant effects on the engineering properties of soils. Your geotechnical investigation report should give an estimate of shrink/swell potential. Reinforcement is typically conventional steel or post-tension cables. Typically this is due to tree roots spreading under the building and taking the moisture out of the clay. Click Here to join Eng-Tips and talk with other members! Obviously, 5' oc costs twice as much, for twice as many holes.
