What We Do
A foundation is a lower portion of building structure that transfers its gravity loads to the earth. Foundations are generally broken into two categories: shallow foundations and deep foundations. A tall building must have a strong foundation if it is to stand for a long time.
To make a foundation, we normally dig a trench in the ground, digging deeper and deeper until we come to subsoil, which is more solid than the topsoil that is used to grow plants and crops. When the trench is deep enough, we fill it with any strong, hard material we can find. Sometimes we pour in concrete into the trench, which we strengthen even more by first putting long thin round pieces of steel into the trench. When the concrete dries, the steel acts like the bones in our body to tie the foundation together. We call this reinforced concrete.
Once the foundation has been packed down tightly, or dried hard, we can begin to build the building superstructure. A groundworker is a British term for a subcontractor who is employed to prepare a home construction site for the shallow foundation of a new home.
Typically, the groundworker clears the site, lays a foundation, installs drainage and other pipework, and may build roads if necessary. The groundworkers are usually the first and last trades performed on site. They will start the job putting in levels, digging the ground, excavating and concreting the foundations, and building the foundations until the floor is on and the work is up to the damp proof course (dpc).
They are also the team responsible for the drainage; connecting to the existing pipes installing in the new pipes.
At the end of a home build, groundworkers return to put in driveways and footpaths. Groundworkers usually work on a labour, plant and material basis.
