Excavations & Earthworks Services
What Does Our Excavation & Earthworks Service Include?

Bulk Excavation & Site Clearance
We carry out bulk excavation for roadways, foundations, barns, equestrian facilities, treatment plants, and ponds. Our team clears vegetation and debris, then reshapes the land through cut-and-fill operations. Using the right machinery for each job, we create safe, stable, and level platforms ready for construction or development.

Site Levelling & Laser-Guided Grading
Accurate levelling is essential for long-term performance. We use modern, laser-guided grading systems on our machines to create smooth, even surfaces with precise tolerances. Ideal for arenas, concrete slabs, and yards, this method reduces rework, improves drainage, and ensures a compacted, construction-ready surface every time.

Excavation & Lining of Ponds
We design and excavate ponds for farms, estates, and landscaped spaces. Each pond is shaped to suit the land and built with long-term use in mind. Where needed, we install natural clay linings that retain water effectively, reduce maintenance, and help create healthy, biodiverse aquatic habitats.

Soil Screening & Material Re-Use
Our mobile soil screening service separates stone, roots, and debris from spoil, improving soil quality on site. By reusing clean material for backfilling or landscaping, we help clients cut waste disposal costs and reduce environmental impact. It’s a practical, green solution that keeps your site efficient and sustainable.
