Site preparation - Building.

Sunday, December 5, 2010

Turf and vegetable top soil should be removed from the ground to be covered by a building, to a depth sufficient to prevent later growth. Tree and bush roots, that might encourage later growth, are grubbed up and any pockets of soft compressible material, that might affect the stability of the building, are removed. The reasons for removing this vegetable soil are firstly to prevent plants, shrubs or trees from attempting to grow under the concrete. In growing, even the smallest of plant life exerts considerable pressure, which would quite quickly rupture the concrete oversite. The second reason for removing the vegetable top soil is that it is generally soft and compressible and readily retains moisture which would cause concrete over it to be damp at all times. The depth of vegetable top soil varies and on some sites it may be necessary to remove 300 mm or more vegetable top soil.


In practice most of the vegetable top soil over a building site is effectively moved by excavations for foundations, levelling and drain and other service pipes to the extent that it may be necessary to remove top soil that remains within or around the confines of a building.

We didn't realize how important preparation of a site was until we had an addition put onto our house. Luckily our architect mentioned the things you did, and let us know how crucial it was. Thanks to our crew, we had the ground properly prepared before we started, and thus insured a long and happy life for our addition.

I am a builder, and I have to prepare construction sites before laying foundation of building. Whenever I need to level ground or remove garbage, I always call Louis Eksteen, who is the man behind rubbleremovalpretoria.com, and it becomes easier to clear the ground quickly.

The foundation is the most important for a building and it need to be the strongest. Before starting the foundation work, the ground need to be made clean and all the stuffs that may have impact on the foundation should be removed. Trees or bushes are the most important to be taken care of because these stuffs can make the foundation weak later. foundation inspection Santa Monica, CA.
