Prospective land and residential house owners have been suggested to think about soil testing before commencing any construction works on their acquired land.

This is coming from the Head of Geotechnical and Materials Engineering Division of the Building and Road Research Institute (BRRI) of the Council for Scientific and Industrial Research (CSIR).

According to Bernard Ofosu, geotechnical investigations, often known as soil testing, preempts over or under the design of construction projects and in addition cuts down cost for reconstruction.

“You have to know the type and nature of soil that exists at your site. There are different types of soil and these soils have different properties. They are used for specific projects. If you are building and your site is predominantly clay, it’s going to be problematic for your building. When you are building a water retaining structure like a dam, then clay is okay.

“You have to know if the soil can support the structure you want to build. When you build and the structure begins to sink, the cost for rectifying the problem might be more than what you would have spent during the actual building works. Doing these tests would prevent you from incurring costs,” he noted.

In Ghana, a number of houses are reported to be constructed alongside or in mushy areas. These settlements often get submerged by floods, damaging properties.
