Skeleton Steel Framing

For some of our steelworks, buildings require a skeleton steel frame. This is composed of steel beams and columns connected using proper connections. For this, our contractors use steel beams around the perimeter of the structure, termed as spandrel beams, where any masonry walls should be placed.

Wall Bearing Steel Framing

Where structural steelwork building involves a wall bearing steel framing structure, a building wall (whether interior or exterior) is used to carry the end of structural members that support floor or roof loads. Our contractors ensure that the wall bearing is strong enough to both carry vertical reactions and resist imposed horizontal loads.

Long Span Steel Framing

Long span steel framing is what our contractors consider when large clearance is required, meaning that long spanning cannot be realized using steel beams and columns. Long span steel framing structural steelwork options offer options, for instance, girders, trusses, rigid frames, arches and cantilever suspension spans.

Substructure And Groundwork London
Stabilisation Methods

Soil Nails

When it comes to groundwork London and substructure work, soil nail walls are generally constructed from the top down. Typically, the soil is excavated in one to two metre deep stages. Tension-resisting steel bars are inserted into the holes and grouted in place, professional work done properly, using the best equipment and techniques in the business. Tension-resisting steel bars are inserted into holes in a wall and grouted in place.

Ground Anchors

Groundworks construction London involves the use of ground anchors. To do this, steel cables have metal wedges on their ends, and the metal wedge end is driven pneumatically into the slope face to the desired depth. To complete this process, the cable is pulled taut and attached to a finishing plate to maintain tension.

Geosynthetic Materials

During our groundworks projects London we use geosynthetic materials, which can be incorporated into retaining walls and embankments to provide critical reinforcement. Geotextiles are woven to allow the passage of groundwater, and as geomembranes are impermeable, they are typically used as liner materials.



Our groundworks construction London starts with a ground investigation as we know that every site is unique. This ground investigation which helps our groundwork contractors London placed identify key issues of concern such as past land use, the stability of the ground in question and any underlying problems that may cause potential issues in the future.


The second part of groundworks construction in London is the site clearance. Our professional groundwork teams in London are on site to clear and collect the topsoil in its entirety. If it is needed, our groundworks contractors in London will also level the land if the site is sloping, using a level development platform.


Ground stabilization covers all the work below the underside of screed or in instances where there is no screed, the underside of the lowest floor finishes including damp-proof membrane together with relevant excavation and foundations. Our groundworks contractors London also do the setting up of temporary or permanent drainage as well as other utility connections.

Solid Groundwork Construction
Helps During Flooding

As a professional groundworks company in London we know that, In the event of a serious flood, a solid building foundation may not be enough to save possessions from water damage, though it will ensure that the property will remain standing with structural integrity intact.
