Trial Pit Excavation & Backfilling in Holbury, New Forest

Ground Investigation & Infiltration Testing Support in Hampshire


At JS Landscapes & Groundworks Ltd, we recently completed a trial pit excavation and backfilling project in Holbury, New Forest, supporting essential ground investigation and infiltration testing works.

Working to the instructions provided, our team excavated the required trial pits to allow the necessary investigations and testing to take place. Once the works were completed, we returned to backfill the excavations, leaving the site safe and tidy.


What Are Trial Pits and Why Are They Needed?

Trial pits are excavations carried out to investigate ground conditions before construction, development or drainage works begin.

They can provide valuable information about soil composition, ground conditions and the suitability of a site for proposed works.

Infiltration testing is commonly undertaken to assess how effectively water drains through the ground. The results can help determine whether soakaways or other infiltration-based drainage systems are suitable for a particular site.


Our Recent Groundworks Project in Holbury

For this project in Holbury, our team was instructed to carry out the excavation and subsequent backfilling of trial pits as part of the site's ground investigation process.


Our works included:

  • Excavating trial pits in accordance with the instructions provided.
  • Providing access for the required ground investigations and infiltration testing.
  • Backfilling the excavations following completion of the testing.
  • Leaving the working areas safe and tidy upon completion.


These works formed an important part of the investigation process, helping facilitate the assessment of ground conditions before further project decisions could be made.
