Groundwork Contractors Croydon

If you are comparing quotes from groundwork contractors in Croydon, it helps to know what actually drives the figure. The price is set far more by what sits under the surface than by the size of the plot. Excavation depth, the volume of spoil leaving site and how that spoil is classified all move the number, and ground contaminated by former industrial or garage use costs considerably more to dispose of than clean clay.

Access is the other main factor. A site with room for a 13 tonne excavator and a rear tipper will always work out cheaper per cubic metre than one where we are limited to a micro digger and grab lorries booked into slots. We set all of this out line by line at quote stage, so you can see where the money is going before you commit to anything.

Parts of the borough carry a recognised surface water flood risk, and most new commercial development here now has to show that runoff is managed on the plot rather than pushed into an already loaded sewer network. In practice that means attenuation, permeable surfacing, soakaways or a combination of the three, sized against a discharge rate agreed with the lead local flood authority.

We install the full drainage package to those approved details, including attenuation crates, silt traps, petrol interceptors on parking areas and flow control chambers. On completion we CCTV survey and test the runs, then hand over the record drawings and results your building control officer will ask to see.

Groundwork sets the pace for everything that follows, so we build the programme backwards from your slab or steel date rather than forwards from ours. Before we mobilise we confirm setting out with your engineer, agree levels, and check that utility diversions and service disconnections have been booked. Those lead times are the single most common reason a start date slips.

On site we work in defined stages with hold points for inspection, so foundations are signed off before we pour and drainage is tested before it is backfilled. You get a weekly update on progress against the programme, and any variation is priced and agreed in writing before we carry it out.

We take on groundwork contracts for main contractors, developers, housing associations, managing agents, schools and private landlords across Croydon, Purley, Coulsdon, Thornton Heath, Selsdon and Shirley. Recent work has covered newly built residential plots, school and nursery grounds, industrial yards, retail forecourts, community sports facilities and private estate roads.

Contracts range from a single foundation and drainage package on a rear extension through to full enabling works on a multi-plot development. We are equally comfortable slotting in as a groundwork subcontractor on someone else’s programme or acting as your only point of contact from site clearance to finished slab.
