Whether you’re planning to build a new home or renovate your current one, you’ll need a good local groundworks contractor. These professionals can ensure your building is strong and stable, reducing the risk of rework and knock-on costs in the future.
When undertaking a construction project, it’s essential to work with local groundworks contractors who understand the specific requirements and challenges of your area. One such reliable company is Dobson Driveways, which specializes in driveway construction and other groundwork services.
Before construction can begin, most local authorities require a ground investigation to identify past land uses and potential problems with the site. This includes geology, hydrogeology, and soil conditions.
Ground Investigation
Ground investigations are conducted to understand the ground conditions for foundations, retaining walls and soil improvement. They can also be used to determine if a site is prone to landslides, mudslides and flooding.
During the investigation, several borings are made at the site and disturbed and undisturbed soil samples are taken for visual observation and laboratory testing. Tests will include moisture content, plasticity index, particle size distribution and bulk density tests for cohesive soils and shear box tests for granular soils.
Geotechnical engineers use the results of these investigations to design structures that are both safe and durable. They can also use the information to help clients save money on construction costs and reduce risks.
Site Clearance
Site clearance is a process that involves the removing of unwanted surplus materials and rubbish from a construction site. This work is necessary before a building can be constructed.
It may also involve the relocating of underground infrastructure, soil, rubble and other waste material. This can be a time-consuming and expensive process, so it is best to hire a professional site clearance team that has the experience and equipment needed to do this job quickly and efficiently.
A good site clearance company will dispose of the waste properly and make sure that it does not cause any damage to the environment. They should also have the appropriate permits and licences to ensure that they can legally carry out this work. They should also be able to provide advice on the proper disposal of waste and hazardous materials.
Retaining Walls
Retaining walls are an essential part of many construction projects, allowing level areas to be created on sloping sites to maximise development space. They are also used to form the walls of basements, underground car parks and metro stations in towns and cities.
They are designed to restrain soil, or engineering fill, at an angle steeper than the material’s natural incline – the steepest angle it can hold without collapsing. This is done to withstand the horizontal – or lateral – earth pressure that is exerted by the material behind the wall, which is determined by both the height of backfill and its density.
Retaining walls can be an important safety measure for both residential and commercial properties, as they prevent slope failures and water erosion by retaining the soil around foundations and driveways. They can also be a significant asset to landscapes, providing a practical means of managing slopes and promoting adequate drainage, which will prevent flooding in your garden or yard.
Sheet Piling
Sheet piling is an effective method of retaining and supporting excavations. It can be used on temporary and permanent projects in marine, transportation and foundation design.
Typically, sheet piles are constructed by driving prefabricated sections into the ground. Depending on soil conditions, these sections may be vibrated instead of hammer driven.
There are many different styles of piling available for use, ranging from flat sheets to U and Z-shaped pilings. These are generally used for water front structures such as in building wharfs, quays and piers.
Sheet piles can be made of timber, reinforced concrete or steel. Steel sheet piles are the most commonly used type of piling and offer high resistance to driving stresses, excellent water-tightness, and can be increased in length either by welding or bolting.
