Excavation Methods


Excavation is mainly put into two categories, task-based excavation as well as excavation based on material removed. Therefore, based on the excavation needed, an expert excavation contractor makes the decision on the technique along with machinery that works best for the work at hand. For the excavating service to be done excellently, best companies such as Van Adrighem offer the ideal excavation machinery based on the task type. The excavation is implemented in digging basements, removing sediments from ponds, assisting in building bridges among other operations. The article outlines the excavation types based on categories.

Excavation based on material

Topsoil Excavation

This excavation type is particularly used to remove the topsoil which is the uppermost level of soil in the surface of earth that is normally no more 12 inches. The excavation method gets out decaying materials, soil, vegetations that have the possibility of making the soil compressible as well as infit to bear structural loads. The topsoil is also removed because it has high moisture content.

Muck Excavation

Muck, combination of soil and water, usually causes problems in the construction sites since it makes the ground unsuitable as well as unstable for building. The good thing is once the much is excavated, it is possible to either move it to another area or spread it out to dry, then reuse it.

Earth Excavation

This process is the removal of soil under the surface topsoil, the digging is deepened based on the type of project. The removal of these various layers enables the construction firm to lay foundation for various construction types such as building drainage ditches, constructing bridges among other engineering projects.

Excavation based on Task

Drainage Excavation

The purpose of drainage excavation is to alter the flow of water from specific areas; hence the procedure must be accurate and done correctly to ensure the drainage remain unblocked and run freely. Drainage is connected to carrying water away from certain areas which comprises of drainage for runoffs, agricultural drainage, storm drains trenches and so on. The drainage is used to direct water from particular areas such as infrastructure, habitation along with agriculture.

Bridge Excavation

These three types of bridges suspension, beam as well as the arch require a sturdy foundation to build on.The bridge excavation process should be well informed to support the weight of the bridge above. The purpose of bridge excavation is to remove materials that might curtail the construction of the foundation, bridge footing, abutments as well as substructures of the bridge.

Due to advancement in technology, companies today can invent machinery that are more effective and efficient in the construction and engineering industry. Excavation is made up explosives and tools used for moving rocks, soil among other materials. The type of excavation techniques discussed in this article are bridge excavation, drainage excavation, earth excavation, muck excavation along with topsoil excavation. It is also worth noting that there are two main categories of excavation  types: excavation based on task and excavation based on material.
