In-SITU COMPACTION

Innovative quality, from start to finish.

In-situ compaction refers to the improvement and stabilisation of existing base materials onsite, rather than importing external soil. This requires thorough analysis and suitable equipment to get effective results.

Some in-situ soils are too loose in their natural state to facilitate construction on the site within acceptable settlement tolerances. This is addressed by increasing the soil density with in-situ compaction of the natural ground strata to achieve the required strength and stiffness.

Dynamic Compaction Solutions in-situ compaction capabilities with HEIC

Rock Fills

High Energy Impact Compaction (HEIC) compacts rock fills through ‘rubblisation’ of in-situ materials. In other words, breaking down large rocks into smaller particles with the use of dynamic compaction applications.

Mixed Fills

HEIC significantly benefits mixed fills in mine rehabilitation, infrastructure projects, stacker/reclaimer alignments, and mine haul roads, boosting uniformity, stability, and quality for improved construction efficiency and cost savings.

Shingle/ Rock

In-situ compaction reduces the need for removal and resurfacing of shingle/rocks from construction and mining sites as it reduces particle sizes over the course of multiple applications.

Before / After 25 surface passes

Sands

In-situ compaction reduces the need for removal and resurfacing of shingle/rocks from construction and mining sites as it reduces particle sizes over the course of multiple applications.

Pre and post sand reclamation CPT results to 18 feet

Sandy Clays

Dynamic Compaction Solutions in-situ High Energy Impact Compaction (HEIC) offers a targeted solution to the unique challenges of sandy clay compaction in construction, significantly enhancing soil stability and load-bearing capacity directly at the construction site.

Saturated Alluvial Soils

High Energy Impact Compaction (HEIC) provides significant benefits for saturated alluvial soils, enhancing their stability, consolidation, and overall performance.

Liquification Mitigation

Field trials confirmed:

Liquification induced free field settlements in the upper 10ft were reduced 40% to 90%
Liquefiable layers tended to be located generally within the upper 10ft of the soil profile
The geotechnical investigation identified the site is predominantly beach and dune sand

Contaminated sites

HEIC is able to confine asbestos and other pollutants in-situ, eliminating environmental concerns related to material loading, transportation, and disposal.
Significant time and cost savings, exceptional efficiency, and a greener alternative to excavation, export, import, and 12″ layer compaction
Reduces carbon footprint and minimises exposure of hazardous materials to both people and the atmosphere

What our  clients say

“Dynamic Compaction Solutions was able to use HEIC to compact the building pad, parking, drives, and fields for 20% less than the cost of installing geo-piers at the building pad only. This process fast tracked our schedule by 3 weeks.”

Vaughn (GC)

“The result of our study indicates the HEIC process from Dynamic Compaction was effective in improving ground conditions and reducing the risk for potential foundation, floor slab and pavement movement that could occur as a result of the loose and medium stiff clayey sand and sandy clay soils encountered below the site. Based on our observations of the plate load test and or additional borings, we believe the subsurface conditions have been significantly enhanced since our original Geotechnical Engineering Report and our recommendations remain appropriate.”
