Site excavation contractors

Castle Oak offers a comprehensive range of site excavation services to clients in Hertfordshire and the UK – either on a contractor basis, or as part of your turnkey design and build team. With our support, your site will be prepared to the highest standards ready for the next stage.

Our site excavation services

While your primary focus of your project will probably be the construction phase, the bits that you can’t see are just as vital as the bits you can. Any building project starts with strong foundations – and to lay them, the site must be excavated and prepared to the finest detail.

Staking and clearing

Our site excavation specialists will map out the boundaries of your new build or development, identifying issues and obstacles which are then removed in the subsequent clearing stage.

Site excavation

With all plant machinery provided by ourselves, we’ll move quickly onto site and start the excavation process, arranging crushing, screening and disposal of waste according to requirements.

Grading, backfilling, compaction

Our contractors will ensure a completely stable and level foundation for the build, using our extensive knowledge of grading, backfilling, levelling, compaction and erosion control.

Supporting services

Managing every aspect of your construction project, our excavation team works alongside our civil engineers and groundworks experts to bring you continuity, consistency and efficiency.
