Secure Sites
We self-deliver the full groundworks and civils package across secure, restricted-access and operational environments — secure facilities, defence and MOD sites, utilities and live operational estates — with vetted teams, controlled access and minimal disruption to the operation around us.
Start the conversationGroundworks that fit around the operation
EJ McGrath has genuine experience delivering civils and groundworks behind the wire. Secure and operational sites don't pause for the construction programme: access is controlled, the perimeter has to stay intact, and the works have to be sequenced around live security and day-to-day operations. We're set up for exactly that — our own vetted operatives, controlled escorted deliveries and methods built around keeping the site secure and disruption to a minimum.
Because we self-deliver each discipline with our own people and plant rather than subcontracting it out, there are fewer faces through the gate, clearer accountability and more certainty on a site where certainty matters most.
- DBS & EL1-cleared, security-vetted operatives
- Controlled, escorted deliveries and logistics
- Methods sequenced around live security operations
- Minimal disruption to the operational site
Full civils scope, securely delivered
The same self-delivered groundworks and civil-engineering package we bring to any scheme — adapted to the access, vetting and sequencing a secure site demands.
DBS-checked & vetted operatives
Teams cleared to work on secure and operational estates — vetting and security checks completed before anyone steps on site.
Security-cleared logistics
Controlled, escorted deliveries and plant movements planned around the site's access and search procedures.
Working within secure perimeters
Methods built to keep the perimeter intact and the operation running — sequenced around live security and daily routines.
Full groundworks & earthworks
Bulk and detailed excavation, muck-away, capping, piling mats, remediation and site preparation.
RC & substructures
Foundations, pile caps, ground beams, structural slabs and retaining walls — formwork, rebar fixing and quality concrete finishes.
Drainage & external works
Foul and surface-water drainage, attenuation, ducting, roads, hardstandings and hard landscaping.
Safe digging around live & buried services
On sensitive and secure sites, what's underground matters as much as what's above it. Our in-house vacuum excavation gives us a safe, non-mechanical way to dig around live and buried services — and it's run by the same DBS & EL1 security-cleared people who work the rest of the site.
Vacuum excavation — our own T-VAC 2
Our in-house T-VAC 2 vac-ex unit excavates quickly and safely around live services — no destructive hand-digging. It's delivered on our own transport and run by our own teams, so it's available exactly when the programme needs it, and ideal where ground conditions, buried services or security make mechanical digging the wrong call.
- Fully trained operators
- DBS & EL1 security cleared
- Delivered on our own transport
- Operated by experienced groundworkers
One team you can clear once
Self-delivery means fewer people through the gate, one point of accountability and a team that already understands how to work safely inside a live, restricted-access environment.
- Vetted, DBS & EL1-cleared people — including our vac-ex crews
- Own teams, supervision and plant — fewer subcontract interfaces
- CDM-compliant, QA-led methods and safe sequencing
- Experience across secure, live and restricted-access settings
Accredited, compliant and cleared
Independently accredited for safety and competence — SSIP, Constructionline Gold, SMAS Worksafe and Cyber Essentials — with DBS and EL1 security clearance for personnel where secure-site access requires it.
Certified to deliver, safely
