In construction, earthworks are unavoidable. If building is a lifetime project, earthwork doing is the insurance of this life project. Indeed, earthworks are a guarantee of stability and durability for a future building or structure. It consists of optimally preparing the ground that will accommodate the infrastructure. And depending on the specificities of the land, earthworks involve operations that are as complex as they are varied. If in general such work is entrusted to professionals in the construction trades, it is also wise to know the basics to better guide and carry out a project. It would even be possible to undertake this work yourself for an individual project. But then how
\nto define earthwork ? Why is it necessary ? How is it conducted and what are the different types ? And how much do earthworks usually cost ?

Earthwork: definition and principle<\/h2>\n

What are earthworks ?<\/h3>\n

Imagine yourself in possession of a sloping land or whose surface is irregular and on which you plan to build ! Unless you want to create an architectural work that defies the laws of nature, you must level your ground first. And that’s where earthworks<\/strong> come in.<\/p>\n

Earthwork<\/strong> includes land development operations<\/strong> with the aim of setting up a construction there. In other words, it consists in preparing a ground<\/strong> on which you want to build or reinforce a structure (building, road, dam) or carry out an external installation (terrace, garden, swimming pool, garage, car-park, etc). This is a capital point of the structural work in the steps of a house building<\/a>.<\/p>\n

Earthwork principle<\/h3>\n

To do his job, the digger<\/strong>, equipped with the appropriate equipment such as earthmoving machinery<\/a>, will shape the soil<\/strong> by digging it in specific places and moving large quantities of earth. It is as a true field sculptor that he works. And depending on the ground aspect, he can also bring earth to it in order to fill in concave zones. Earthworks<\/strong> are said to consist of digging and filling earth<\/strong>.<\/p>\n

Excavations carrying out<\/h4><\/div><\/div><\/div>\n

\"Excavation<\/div><\/div><\/div>\n

Excavation<\/strong> consists of removing earth or rubble from land<\/strong> in order to level or lower it. Different techniques can be used to achieve this depending on the type of soil (rocky, loose, etc.). For example, it is during excavation work<\/strong> that a mechanic shovel will dig a trench where pipes will later be buried.
\nAfter earth extraction, it is transported to the landfill or to the waste collection centre. Depending on the soil quality, it can be sorted on site if necessary to reuse as backfill. It is sometimes also possible to monetize the removed land from operators of farms, quarries or building sites.<\/p>\n

Backfill<\/h4><\/div><\/div><\/div>\n

\"Backfill<\/div><\/div><\/div>\n

A backfilling<\/strong> operation is the addition of materials<\/strong> (earth, sand, gravel, etc.) to the ground in order to level or raise it. The backfill<\/strong> can then be compacted with a construction machine such as a compactor. The objective of this maneuver is to bridge any gaps in the terrain and obtain a stable construction platform that resists natural ground movements. <\/p>\n

Excavation digging<\/strong> and backfilling<\/strong> bring the natural terrain with its roughness and faults to the technical level required by the project.<\/p>\n

Why are earthworks important ?<\/h2>\n

A civil engineering work or an outdoor development offering guarantees of safety first requires successful earthworks<\/strong>. Indeed, earthworks<\/strong> make it possible to properly establish the structure to be built. Since each construction project has its own specifications, the land must be adapted to the project requirements. Earthworks therefore correct the morphological defects of the soil<\/strong> in order to make it suitable for the construction. Thus, soil can be stable, solid and resistant, without putting its users in danger of flooding, subsidence, landslide, collapse or other dangerous ground deformations.<\/p>\n

Moreover, it is thanks to the earthworks<\/strong> that the ground is optimally prepared for connection operations to the various networks (electricity, drinking water, telecommunications, etc.) and water drainage. <\/p>\n

In short, a well-graded site facilitates construction work and ensures the quality and durability of the structure to be carried out<\/strong>. Neglecting this step can later lead to serious damage requiring heavy and expensive repairs.<\/p>\n

LGU Afrique<\/strong>, it’s nearly two decades of expertise and experience in construction and renovation.<\/p>\n
