Before embarking on the construction of a new house, it is necessary to go through a series of steps all mandatory and necessary for the smooth progress of the work. One of them is the backfilling of land. This very important step should not be overlooked as it provides a solid and stable foundation for future construction. Find out what is the use of backfilling and how to proceed.
Why fill a land?
The backfilling is very important because it allows to prepare and shape a land to accommodate a new construction. If you are building a house or doing an extension, or if you decide to create a garden or a terrace, you will need to fill in your land as this will stability necessary to future structure.
Backfilling is also useful for raise a floor, recreate a slope, or fill gaps or trenches. For backfilling, usually earth, inert waste, extraction earth, pebbles, limestone or rubble are used. It will depend on the nature of the soil and the construction. Backfilling is part of the earthworks and is done after the demarcation of the land.
Backfilling: How to proceed?
Before backfilling your land, it is mandatory to make a declaration beforehand or to ask permission according to the height, the surface and the location of the embankment.
The works must respect a certain regulation specific to the use of the grounds and the principles of protection of the environment. Once you have obtained all the necessary authorizations, the backfilling can then begin with a stripping of the topsoil before proceeding to the realization of the trenches and the installation of the eyes and the pits. The ground is distributed on the ground according to the form that you wish to give to the ground. It is advisable to use a tracked machine for stabilization. Be aware that the earth tends to get bogged down by the weight of materials. Count on a 15% average settlement (varies according to the nature of the soil). An embankment consists of a layer of large stones, a layer of crushed stone and a top coat of sand or gravel. The stabilization of the embankment can last between 1 to 10 years. It all depends on the nature and thickness of the embankment.
