GroundWorks

We offer a variety of skills here at Bmc Builders at competive prices for groundworks

We undertake excavations on large and small jobs of the footings down to the concrete pour. we also do drive ways of may sorts; concrete, shingle and block pave to give a satisfiying finish.

Strip footing:

A strip foundations consist of a continuous strip, usually of concrete, formed centrally under load bearing walls. This continuous strip serves as a level base on which a wall is built from and is of such a width as is necessary to spread the load on the foundations to an area of subsoil capable of supporting the load without undue compaction. Concrete is the material principally used today for foundations as it can readily be placed, spread and levelled in foundation trenches, to provide a base for walls, and it develops adequate compressive strength as it hardens to support the load on foundations. Before {Portland cement} was manufactured, strip foundations of {brick} were common, the brick foundation being built directly off firm subsoil or built on a bed of natural stones.

Raft Foundation:

Raft foundations are used to spread the load from a structure over a large area, normally the entire area of the structure. They are used when column loads or other structural loads are close together and individual pad foundations would interact.

A raft foundation normally consists of a concrete slab which extends over the entire loaded area. It may be stiffened by ribs or beams incorporated into the foundation.

Raft foundations have the advantage of reducing differential settlements as the concrete slab resists differential movements between loading positions. They are often needed on soft or loose soils with low bearing capacity as they can spread the loads over a larger area.

 

Drainage:

Laying a land drain, or French drain is the easiest method of dealing with surplus water in your gardenThis type of pipe is easily laid in small trenches and surrounded by shingle (small stones) to allow water through but filter out silt.

An integral part of any drainage system are the access points into it when it comes to cleaning, clearing and inspection, however the number and construction of any chambers at your property, if any will be largely dependant on its age.

Building regulations as we know them now came into force on a national scale in 1966 with properties built prior to this being subject to local public health acts and local by-laws and housing acts which could vary greatly from one area to another.
