Micropiles — installation and ground treatment overview

HOW IT WORKS

Installation sequence

01

Drill

Select drilling and bore support for the ground and access conditions.

02

Install & grout

Install reinforcement and grout using the approved sequence.

03

Verify

Record pressures and volumes and perform specified verification tests.

APPLICATION & ENGINEERING

Restricted-access foundations and underpinning

Small-diameter steel-reinforced grouted elements can transfer loads where access or headroom limits larger rigs.

When to choose this method

Micropiles can support restricted-access works and underpinning where conventional rigs cannot operate. The load-transfer mechanism depends on the reinforced element, grout and ground bond, with the connection to the supported structure designed as part of the system.

Planning the installation

The ground investigation, groundwater conditions and structural requirements inform method selection. Working access, installation sequence and effects on neighbouring structures are reviewed before execution.

Construction control points

  • Select drilling and bore support for the ground and access conditions.
  • Install reinforcement and grout using the approved sequence.
  • Record pressures and volumes and perform specified verification tests.

Check drilling records, reinforcement and casing details, grout mix and injection records. Verify load performance through the specified test programme.

Engineering considerations

  • Geotechnical report, groundwater and nearby structures.
  • Approved design, access and working-platform requirements.
  • Installation records, inspection and specified acceptance tests.
