Groundworks are vital to the success of any construction project, whether it be an entire new build or a small extension. Operations such as preparing the ground, digging foundations, installing adequate drainage and much more, are what makes a structure stable and strong. Our complete coverage of West Sussex, Hampshire and Surrey sees our groundwork contractors carrying out a comprehensive range of groundworks for customers across the South East. Here, we explain some of the main services involved.
Prior to the build of a new structure it is recommended, not to mention legally required by most local authorities, that a ground investigation be carried out at the site. Involving surface and subsurface explorations, this allows important geotechnical data to be gathered to gain a deeper understanding of site conditions. Our groundwork contractors use various investigatory methods, such as drilling techniques, to recover and test soil and rock samples. Ground investigations are important to make sure the land is suitable for building on.
Once planning permission is in place and scheduling drawn up, the main groundworks can begin. The first step is to clear the site for construction, which could involve everything from the demolition of an existing structure to the removal and disposal of rubbish. Because we operate as licensed waste carriers, we can take rubbish and earthworks lifted to local recycling plants ourselves. We have excellent connections with recycling companies across West Sussex, Hampshire and Surrey including in Southampton and Portsmouth.
After the site has been cleared, our groundwork contractors can carry out any required excavation work. This involves removing earth, rock and other materials. Excavations are often needed to create better ground conditions for your project, such as to reach more stable soil for the construction of an extension. The shape, size and depth of the excavation is dependent on the type of construction and existing soil condition. Shoring is often needed for deep excavations, which are classed as any excavation more than 4.5 metres in depth.
It is important to know where any existing drains are located and to plan and install new drainage carefully. If building a completely new structure, you will also need to know where a connection to the mains system can be installed. As drainage specialists and groundwork contractors, you can trust James Hennessy Construction to handle any drainage requirements with ease. We will ensure new drains are installed at the right depth and gradient. We can also take care of the installation of septic tanks and much more.
Foundations are the main support for structures of all kinds. They distribute the weight of the structure, help to avoid unequal settlement, increase structural stability and prevent the lateral movement of the structure. Various elements are carefully calculated by our civil engineering contractors, to establish the correct depth, foundation type and methods to use. Shallow or deep foundations can be used for building constructions and a popular technique is to pour concrete into trenches to create a strong and durable foundation.
