Excavation is a key part of many construction and renovation projects. If you're looking to find out more about the different types of techniques used in the construction industry, this is the article for you. Read on to find out more.
1. Channel excavation
Channel excavation involves removing earth or sediment from an existing channel such as a river or canal. Channel excavation is generally done to widen an existing channel for use in larger vessels or increase the depth of a channel in order to avoid hazards such as flooding. This approach is sometimes used to divert the path a watercourse takes over a piece of land.
2. Drainage excavation
Drainage excavation is a type of excavation technique used for digging ditches that will carry stormwater away from structures like building foundations. The depth of a drainage ditch must be deep enough to allow water to flow freely, but not too deep as to present a hazard. Drainage excavations are often lined with concrete and fitted with gates to control the flow of water.
3. Topsoil excavation
Topsoil excavation is a type of excavation technique used for preparing dirt for use in landscaping. If you plan on using dirt in landscaping, chances are you're going to need to remove the existing topsoil from the area first. This is because topsoil is considered one of the three essential components of soil, along with subsoil and bedrock. Topsoil can be removed by digging it up or by removing it mechanically using a large farming tool called a power rake. The power rake lifts soil up from plot areas and transfers it through a conveyor belt into trucks which transport the material back to your storage area.
4. Footing excavation
If you're planning to build a structure on new ground, footings will probably be required. The purpose of footing excavation is to provide a stable foundation for your building. They are mostly used when constructing large buildings or structures such as bridges and roads. Once the area has been excavated, concrete is poured into the cavity to create a solid base on which to construct a new building.
