Our Groundworks Services

Site Clearance and Levelling

Onyx Contractors provides a professional and reliable site clearance service for projects in all sectors. This covers any general or specific clearance, such as foliage, trees and all hard materials. Our groundworks contractors can also uplift and dispose of existing surfaces.


Our company meets all excavation needs, be it in a garden, on a slope or hillside, digging out trenches or general muck shift excavation work. Of course, we also undertake digging out for foundation installations.

We can redistribute excess soil to another part of your site or take it away. You can rest assured, we make all necessary provisions for utilities and drainage systems already in the ground.

Foundations and Footings

As you would expect from time-served groundworks contractors, we specialise in all forms of foundation construction, including:

  • Traditional Strip Footing

  • Concrete Ring Beam Foundations

  • Piling Footing

  • Raft Footing

We also carry out underpinning and reinforced concrete works.

Whether you’re building a house extension in Farnham, a new build in Guildford or a commercial unit in Godalming, we appreciate that you require a prompt, professional finish. Onyx Contractors does whatever it takes to complete foundation construction works within the agreed timescale and budget.


Our drainage systems guide surface and foul water to the correct destination. Poorly planned or executed drainage solutions lead to major issues sooner rather than later. If your project doesn’t have an engineer’s design in place, we can plan the drainage system for you, ensuring the levels work and that the system has a correct design in line with your needs and wider project.

Well-designed drainage systems avoid problems like ground contamination, sewage blockages and flooding, all of which can damage your home or building.

As your groundworks contractors, we take care of:

  • Sewage Treatment Plants

  • Rainwater Harvesting Tanks

  • Septic Tanks

  • Mains Drain Connections

  • Drain Connections in the Highway

  • Sewage Holding Tanks/Cesspools


We level and prepare the ground before laying a surface from our range of supplied materials. These include concrete, block paving, gravel, resin and tarmac.

Concrete Surfaces

Our team meets all concrete flooring requirements. You can count on us for precision laser concrete floors, hand-screeded surfaces, external yard slabs, re-bar/steel fibre, steel decking and high-tolerance concrete floors.

We draw up formwork and falsework solutions for simple and complex cast-in-place concrete structures. Our staff holds knowledge about the leading, and most popular, concreting systems from major formwork manufacturers on the market. This allows us to design efficient concrete schemes based on the advantages of the various formwork systems.


From Guildford to Godalming, our Farnham-based groundworks contractors can cover areas of any size with a selection of natural or manufactured stones.


Onyx Contractors supplies ballast, sand and other aggregates for use as building materials. We also provide gravel and stone chips for surfacing paths and driveways.

Soil Delivered or Removed

We can deliver premium topsoil to your site and have excess soil and other natural materials removed.

Diggers, Dumpers and Tractors

Our company owns a wide range of plant, and our personnel are experienced in its use. This allows us to improve overall project efficiency which, in turn, helps to keep costs down.

Qualified specialist mechanics regularly inspect and maintain our plant, all of which have annual test certificates. To ensure you receive only the highest quality work, all our staff hold CPCD certificates and stay up to date with relevant Health & Safety legislation and requirements.
