Building The Site Risk-Free With A Strong Foundation


There are certain types of soil and foundation systems that if used well can-do wonders. It can help to choose the right foundation option that is needed during site construction. While considering the right foundation on clay soil, it is important to keep different factors in mind too. As the clay soil gets dried out there will be minute cracks and shrink that will be noticed. It further would leave a gap around the house from which the water can enter during the next storm. Further, it can get worse and affect the foundation as well.

Making the right use of foundation on clay:

Different clay soil grades are present across the globe. First clay soil comes with high plasticity that can have a high content of moisture. Then comes the 2nd type of clay soil that has medium plasticity. It does not have much moisture content and has a moderate effect on the overall foundation. In the third type, the plasticity is quite low and so is the moisture content too.

To make the right use of foundation on the clay soil, its depth matters too. Now the depth of the foundation to be used in the clay soil entirely depends on the high plasticity. This can also be around 1m deep or 0.9m deep if there is low plasticity.  Of all the right foundations on clay soil could be the raft foundation. It is best when the clay soil is quite a hard bearing and compact in nature. There are also other types like strap foundation that are best for the medium clay as the soft clay sand is likely to share and expand often.

Factors affecting the foundation systems and soil types:

The decision of foundation on the clay soil can only be understood if the type of the soil is clear. Those who want to extend their home or build a new one need to have clarity on the same. The building foundation price is one of the biggest variables. Those who want to control their schedule and budget must work well on the foundation system to use it as early as possible.

Further to identify the cost-effective solution, another factor on which foundation and soil type depends is the condition of the ground on the site. This means the soil type can be rock or aggregate and has certain key constituents as well.

To be sure about the soil clarity and the site condition, the right inspection should be done. A geotechnical study should be followed that shall have a process of digging trial holes on the site of where the construction will be done. This will give clarity on the soil’s load-bearing capacity at different depths.


From the above details, it is obvious that soil investigation for the whole process can be helpful. Though it is not mandatory if done rightly can save a lot of time and risk too. Different sites usually begin without any formal soil investigation. It relies either on the designer’s knowledge or the local expertise. But as time has changed so has the technology which is why soil investigation can be of great help.
