Ground Improvement

Ground improvement services include aggregate piers, vibro compaction, vibro replacement, jet-grouting, permeation-grouting and soil mixing.

VIBRO COMPACTION

Ground Improvement method in which loose granular soil at depth is densified using a vibratory probe, delivering horizontal vibrations, and repeatedly inserted and withdrawn until the desired densification is reached.聽 Generally performed on a prescribed grid pattern.

Advantages

  • Cost-effective compared to other foundation options
  • Effective above and below the water table
  • Faster than other foundation options
  • Can increase angle of internal friction by 5-10 degrees

VIBRO REPLACEMENT (STONE COLUMNS)

Ground聽improvement聽method in which loose granular soil at depth is densified using a vibratory probe delivering horizontal vibrations and repeatedly inserted and withdrawn and replacing the聽displaced soil聽with stone backfill until desired聽densification聽is reached.

Advantages

  • Cost effective compared to other foundation options
  • Effective above and below the water table
  • Faster than other foundation options
  • Can increase angle of internal friction by 5-10 degrees

NON-VIBRATORY STONE COLUMNS (AGGREGATE PIERS)

Short stone columns, acting as piers installed with rotary displacement tooling.

Advantages

  • Rapid installation
  • Cost-effective compared to other foundation options
  • Creates additional drainage paths
  • Allows for high level of compaction
  • Efficient QA/QC procedures

JET GROUTING / PERMEATION GROUTING

Jet Grouting 鈥 A soil improvement/replacement technique using high-pressure fluids using any combination of grout, air and water, while carefully controlling installation parameters, to create an improved mass of soil in terms of compressive strength and water tightness.

Permeation Grouting 鈥 Filling of cracks, joints, or other pore space in non-cohesive soils, sand or other porous media, using cementitious and/or chemical grouts.

Advantages

  • Can work in tight working conditions and low-overhead
    environments
  • Computer monitoring of grouting shows real-time analysis of
    construction process
  • Can be used in most soil types
  • Can be installed under existing structures

DEEP SOIL MIXING

The mechanical mixing of soil in-situ performed with a paddle-style auger tool using a cementitious binder to create an improved mass of soil, in terms of compressive strength and water tightness.

Advantages

  • Can be used to stabilize peat and other soft soils, and to treat contaminated soils
  • Can stabilize large blocks of soil
  • Quicker and less expensive that many other alternatives (such as mass replacement)
  • Lower environmental impact than other solutions
  • Traditional binders of common materials

CUTTER SOIL MIXING

The mechanical mixing of soil performed with a rotary wheeled mixing device using a cementitious binder to create an improved mass of soil, in terms of compressive strength and water tightness.
