Groundworks Contractors in Okehampton & West Devon
Groundworks and civil engineering for developers and contractors on the edge of Dartmoor
JMJ Groundworks delivers groundworks and civils packages for developers, housebuilders and main contractors across Okehampton and West Devon. With Okehampton sitting right on the A30, our teams and plant can reach sites across the town and the surrounding villages quickly from our Exeter base.
Building on the edge of Dartmoor brings its own challenges, from sloping sites and rocky ground to some of the highest rainfall in Devon. We plan earthworks, drainage and retaining structures around those conditions from day one, so your groundworks are built properly and your programme stays on track.

Frequently Asked Questions
Common Questions About Our Okehampton Groundworks Projects
Do You offer civil engineering in okehampton?
Yes. Alongside groundworks, we deliver civils packages including roads and sewers, service infrastructure, deep drainage, attenuation systems and reinforced concrete works. Our team has carried out civil engineering on demanding projects, including aviation works at Heathrow, so we're well equipped for technical packages across West Devon.
Can you work on rocky or uneven ground near Dartmoor?
Yes. Sites around Okehampton can have shallow rock, uneven ground and steep levels. We plan excavations and earthworks around these conditions, using the right plant for the job, and build in retaining structures where level changes need to be held securely.
Can you handle drainage on wet or clay sites?
Yes. Much of the ground around Newton Abbot and Bovey Tracey is heavy clay, and high groundwater is common, especially in winter. We plan drainage, attenuation and excavations around those conditions from the start, and we've delivered groundworks successfully through wet winters on sites alongside lakes and protected trees.
Do you work for housebuilders and developers?
Yes. Residential developments make up a large part of our work, from multi-plot housing schemes to affordable and modular housing. We work closely with site managers to integrate our groundworks into the wider build programme.
How do you deal with drainage in high-rainfall areas?
Drainage is planned from the start rather than added as an afterthought. We install foul, surface water and land drainage to the correct falls with proper bedding, so it copes with heavy and prolonged rainfall. We've also delivered remedial land drainage on sites where the original systems had failed.
Do you work as a subcontractor to main contractors?
Yes. Much of our work is delivered as the groundworks or civils subcontractor to main contractors and developers. We integrate with the wider site team, work to the main programme and coordinate closely with other trades.
Do you work on sites across West Devon, not just Okehampton?
Yes. We cover Okehampton and the surrounding area, including Hatherleigh, North Tawton, Sticklepath, Bridestowe, Sourton and Lydford. Okehampton's position on the A30 means we can mobilise teams and plant quickly from Exeter.
Can you build retaining walls on steep sites?
Yes. We construct retaining structures for sloping sites, including king-post retaining walls, to hold ground securely and create usable, level areas for building.
