Dynamic Compaction


Employing steel weights, known as pounders, weighing 15 to 40 tons released in free fall from a height of 30 to 120 feet.

Earthquake Drains


Corrugated pipe wrapped in a filter fabric installed with a vibrating mandrel in a grid pattern.

Menard Vacuum Consolidation


A proprietary system that used the atmospheric pressure to preload and rapidly consolidate soft saturated fine-grained soils.

Rapid Impact Compaction


Shallow ground densification using energy waves from a hydraulic hammer weighing 7.7 to 9.9 tons that rapidly and repeatedly impacts the ground at 40 or more blows per minute.

Soil Mixing


A mechanical blending of in-situ soils with cementitious materials and other admixtures. It’s used to mitigate risk of liquefaction; support and enhance stability of earthen embankments, dams and levees; create stable working surfaces; and bind contaminants.

Vibro Stone Columns/Aggregate Piers


Columns of compacted granular material installed in fine grained soils to increase rate of consolidation, densify surrounding soils and improve the load bearing characteristics of a soft soil.


Learn More

Vibrocompaction


The in-situ compaction of loose granular soils by penetration of vibratory probe or vibroflot resulting in overall improvement of the characteristics of the surrounding soils.

Wick Drains


A band-shaped plastic core wrapped in a geotextile fabric—installed by both static or vibratory methods into compressible saturated silts and clays on a triangular or rectangular grid spacing.
