What are Groundworks?

Groundworks is a term used collectively for any portion of your construction project which causes damage to the ground. In general, unless your property requires demolition clearance, this is the initial and final stages of work on the site. The stages of groundworks are:

Ground investigation.
Clearance of the site.
Substructure and ground stabilisation work.
Site services.
Landscaping and rehabilitation.

Be sure to choose a groundworks contractor with an established track record for the type of project.

Investigations on the ground

Before any construction work being started, it is common the local authority to state that a ground study needs to be conducted. Even if it isn’t mandatory, it is a good idea. It is much easier to plan the actions before the beginning of a project rather than having to address the issues later and at a higher cost. This can be accomplished through your contractor for groundworks Sheffield.

Usually, ground investigations can save you money by looking at:

Land use in the past. This is a way of identifying issues such as:
Ground contamination that can comprise hazardous wastes and chemicals.
Old mine operations that could result in gas leaks and ground movement.
Structures that are buried, such as cellars, shelters or tanks for oil.
A survey of archaeology might be necessary in certain instances where there is evidence of an antiquated site.
Ground conditions. This includes:
Geology refers to the formation of the soil beneath the site.
Hydrology is the term used to describe the amount of water that is above the surface.
Hydrogeology refers to the subsurface water that is.
Soil condition that examines the soil layers on the surface.
Protecting endangered animals is the area where the ecosystems that are home to rare species are to be secured.

After the ground survey phase, you can evaluate the price of the project. This is due to knowing the kinds of foundations needed. and any other special steps that are needed to address the risks that have been identified.

Site clearance

Clearing the site is following stage in which the site will be removed of topsoil and then the ground is leveled by your contractor for groundworks. This involves forming walls for retaining that are necessary to hold the ground in place.

The site clearance also will look at:

Reduce the risk of erosion and contamination.
Make sure you are aware of any notices necessary by planning. This includes Tree Preservation Orders.
Guard the site against access by access by animals and the public.
Access to a safe vehicle to the construction phase.

Ground stabilisation and substructure works

Substructure consists of all components beneath the waterproof membrane that support your structure. This includes:

Ground stabilisation methods like:
Soil nails are made of metal rods that are passed through plates and then fixed into the correct position.
Rock anchors and ground anchors that are steel plates that are attached with steel cables.
Geosynthetic fabrics are materials made of fabric and membranes which provide strength and seal properties.
Walls that were retained, but excluded from the site clearing works.
The foundations which ensure your building’s stability and create a sturdy and sturdy base. They are typically:
Foundations that are shallow are needed when the weight of the structure is not a significant burden on the soil layer.
The need for deep foundations is when the weight of the structure is supported by soil that is more stable conditions, which are located deeper within the soil.
Piled foundations are needed for support when additional support is required because of unstable ground conditions or a heavy construction weight.
The loose gravel is used to fill in within the soil between foundations.
Basement structures that are built in the base layer.
Subfloor made of concrete screed beneath that damp-proof layer.
Trenching is used to facilitate access to access to services for the structure.


Groundworks contractors are able to lay service for the projects, including:

Final and temporary drainage. It is possible to have separate systems for flood and sewage.
Access to these utilities
Fiber optics and copper phone lines.
Mains water.

In some instances, a tunneled system might be utilized to obtain the requirements for planning approval.

Re-landscaping and landscaping

It is quite common for construction plans to be provided by a post-construction landscaping treatment. This can be:

The slopes and the levels of earthworks.
Walls that define boundaries, fencing, or hedges.
Planting companion plants for trees mentioned in an Tree Preservation Order.
Finalized surface to be used for roads that allow access, pathways and parking spaces for cars.
Fulfilling planning reinstatement conditions.

What are the most common groundwork equipment?

The equipment used to perform groundwork can differ between contractors, these typically consist of:

360 degree excavators.
180-degree backhoe loaders.
Moving shovels.
Compactor plates.
Forward tipping dump trucks.
Ride on and hand-driven rollers.

Why are groundworks important?

As you can see from the various stages of groundwork they are crucial in the overall success of your construction project.

Groundworks will give you a solid base and the foundation to be successful. If you do not conduct a ground survey, you are not in a place in which you are aware of the costs. If your site isn’t properly cleared and stabilized, the subsequent works are likely to be affected. If the substructure has not been properly set, then everything above won’t have the right quality and strength. Insufficient service can result in expensive repairs that may alter the final outcome of the project. In the end, if the proper landscaping isn’t done, the building might not look appropriate in its surroundings.

The groundworks contractor you choose must be experienced in:

Drainage systems for drainage.

Choose a single contractor to supervise the groundwork phase in the development. This gives you the benefit of:

More effective supervision for the task.
A key communication tool to be discussed is the project.
The single responsible person is responsible for mistakes.
More predictability in costs.

It is crucial to ensure that your groundworks contractor is knowledgeable with the kind of project you’re working on. Also, it is crucial to know the conditions on the site as well as local method of planning authorities. One of the last things you would like to pay for is the contractor’s process of learning.


Don’t forget that groundworks are the most important stage in every construction job. If you do the groundwork correctly, you will be able to control rework as well as knock-on expenses in the rest of the construction project.

It’s also the stage which ensures that your structure will function as it was designed to not only at first, but throughout its life.
