Specialist Groundworks & Civil Engineering Contractors
Trusted by leading contractors, developers and engineers
Who we are
Reef is a specialist groundworks and civil engineering contractor. We work alongside main contractors, developers and engineers on the part of a project that has to be right before anything else can begin: the ground, the substructure and everything beneath them.
Our clients rely on us for safe excavation around live services, reinforced concrete, drainage and civil works on sites where there is little room for error. The work is planned properly, run by experienced people and handed over the way it was agreed.
Our services
Four core disciplines, each planned and delivered by experienced people with our own plant, for main contractors, developers and engineers who need the ground done properly.
Vacuum excavation and non-destructive digging around live services and utilities.

Foul and surface water, attenuation, ducting and utility routes, installed and tested.
ExploreSpecialist plant
The T-VAC 2 is a tracked vacuum excavator, and only a small number of contractors in the UK run one. We use it to expose live gas, water, power and telecom services without a bucket going near them.

How it works
Hand digging is slow and a bucket is a risk. The T-VAC digs at machine speed and leaves every pipe and cable where it was.

Why Reef
Every package is planned by people who specialise in the ground, carried out with our own plant and handed over the way it was agreed.
Safe digging, civils, reinforced concrete and drainage are what we do. The people planning your package know the ground and the risks in it.
Vacuum excavation, tracked plant and specialist kit owned and maintained by us, so the programme never waits on hire.
Live services, occupied buildings and controlled sites. Permits, method statements and checks are in place before the first dig.
Progress, changes and costs reported as the works move, so nothing comes as a surprise at handover.

Client feedback
“They priced the package, sequenced it properly and then actually ran it the way they said they would. We were not chasing anyone.”
“Straight answers when things moved on site, and the programme held. That is worth more than the cheapest number on the tender.”
“They handed the site over cleared and inspected, so our follow-on trades were not picking up after them.”

Yes, and most of our work is exactly that. We run packages on operational schools during term time, live clinical estates, hygiene-critical food facilities and secure sites, where vetting, phasing and access control shape the programme as much as the engineering does.
Yes. Our own crews, plant and supervision run the works, so the sequence never stalls while another subcontractor mobilises.
