Vibrocompaction — installation and ground treatment overview

HOW IT WORKS

Installation sequence

01

Plan treatment

Confirm soil suitability, treatment depth and verification plan.

02

Vibrate in stages

Carry out the approved penetration and withdrawal sequence.

03

Check density

Compare pre- and post-treatment field tests against acceptance criteria.

APPLICATION & ENGINEERING

Densifying suitable granular ground

A vibrating probe rearranges granular soil into a denser state. Fines content and groundwater affect suitability; this process differs from installing aggregate stone columns.

When to choose this method

Vibrocompaction densifies suitable granular soils by rearranging existing particles. Soil grading and fines content are important selection factors. Unlike vibro replacement, the principal treatment mechanism is densification of the soil itself.

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

  • Confirm soil suitability, treatment depth and verification plan.
  • Carry out the approved penetration and withdrawal sequence.
  • Compare pre- and post-treatment field tests against acceptance criteria.

Record treatment positions, depth and operating parameters. Compare pre- and post-treatment ground investigation results, such as CPT where specified, with the acceptance criteria.
