Professional Trial Dig Services
Trial digs across Scotland are undertaken by Signet Group to expose foundations, locate underground utilities and confirm ground conditions before construction or civil engineering works begin.
Utility Trial Holes
Locate underground utilities safely and accurately with minimal disruption.
Foundation Exposure
Expose foundations to confirm their depth, condition and construction details for inspection by the client or appointed engineer.
Photographs & Measurements
Record the excavation with clear photographs, measurements and site findings to support the planning of subsequent works.
Our Process
From the initial site review through to reinstatement, our trial dig process is carefully planned to provide the required information while minimising disruption to the surrounding area.
Site Review & Planning
Review the investigation locations, available utility information, access requirements and existing surface conditions.
Careful Excavation
Excavate the required trial holes by hand or suitable mechanical plant while carefully protecting existing services.
Record & Confirm Findings
Take photographs and measurements and provide the findings to the client or appointed engineer for confirmation.
