Everything you need to know about Groundwork in Construction

What are ‘groundworks’ in a construction?

The term groundwork means, preparing sub-surfaces before the construction work is to start. It usually the first stage of construction and includes ground inspection, site clearance, ground stabilization works, site services, and landscaping. A ground investigation is done to know, for which purpose the site had been used in the past, its stability, and any potential problems it might have. This investigation gives important information which can be used for effective designing and helps in determining the possible defects a site can have. Site clearance is done, for when the construction process has to take place.

This includes clearance of the topsoil and leveling off the ground. Site services include temporary or permanent drainage and other utility connections like water, gas, sewage, electricity, etc. Also, existing services such as water and electricity cables need to be altered. And landscapes include earthworks to remodel the site. 

What is the importance of groundwork? 

Many people do not know about groundwork if they are not in the construction world. However, as a homeowner, it is essential that you know about the groundwork of your building. Groundwork service in North West London is the first and foremost important part of a building being constructed. One should have complete knowledge about the groundwork because the weight of an entire building depends on it. It also creates the structure and layout of a building and strongly holds it in place. They play an important role in sturdily keeping a building in place even in harsh weather conditions like earthquakes, thunderstorms, etc. It is the role of a building contractor you have hired, to evaluate and plan the groundwork. It is their sole responsibility to give the complete evaluation report before a construction project is started.

Importance of foundation:

Engineers inspect every site before construction in order to know whether it requires piles, underpinning, foundations, or engineering designs. A foundation interfaces the building and provides strength and support to the system which enables it from splitting, settling, or unbalancing. It supports the load of an entire building and prevents the moisture from seeping in and weakening the structure. The construction of a foundation starts with the decision of its depth, width, marking layout for evacuation, and the centerline of a foundation. If some part of the foundation is above the ground level, then it is covered with earth filling so that it does not come in contact with air, water, light, etc. Once the foundation has been accessed and ready for construction, then there are several things that you should keep in mind.

1. Trench Fill Foundation:

The trench Fill method is mostly used in homes, as it does not require bricks to be laid on the ground. You can simply carry on the project by just pouring concrete at 150 mm level from the ground surface. It is a time-efficient and money-saving process. 

2. Strip Foundations: 

These are ideal to be used for homes that are built on softer soils such as sand. This is because the weight of the house then spreads on a larger surface area. Since these are wider they also use less concrete on the base.

The foundation should be designed in a way that the settlement to the ground is restricted and constant under the building, in order to avoid any damage to the structure. And the net pressure on the building should not exceed its weight-bearing capacity. If this happens, then there are chances that the building might collapse.
