Drilling investigation

drilling investigation graphic

For areas of restricted access, creating minimal disruption.

Drill holes are angled to provide information beneath a building and to assess surface and near surface ground conditions.

Boreholes 10cm (4’’) in diameter are drilled into the ground, returning pulverised rock and dust fragments by compressed air.

Some noise and dust are created.

The location of overhead and underground services (such as gas, electricity and water) are assessed to avoid damage during investigation.

A series of boreholes are drilled. We interpret the drill speed, hammer rate, air flush and returns to give us an understanding of the ground conditions.

After each hole is completed, it is infilled and sealed.

A written report is produced within 2 working days, depending on the complexity of the site.

Our reports include plans, cross sections and borehole logs. Clear advice is provided if mining features are encountered.
