Soil Improvement

Soil improvement is applied to both consolidate existing loose subsoils and sometimes specifically for compaction of newly reclaimed soil.

Hydraulic Fill

Hydraulic fill is material that is dredged from a borrow area or other area and placed at a site to raise the level of the land or build new land.

Land Reclamation

Land reclamation is the process of creating new land by raising the elevation of a waterbed or low-lying land or by pumping water out of muddy morass areas.

Rainbowing

Rainbowing is a method by which trailing suction hopper dredgers place material in shallow areas by pumping into the air through a hose with a nozzle.

Ground Improvement

Ground improvement techniques are used when the behaviour of the fill mass and/or the underlying soil does not meet required design criteria.

Rock Fill

Rock is often encountered during capital dredging projects and this dredged rock can become high quality fill when used within specific guidelines.

Explosive Compaction

Explosive Compaction (EC) involves placing a charge at depth in a borehole in loose soil and then detonating the charge.

Dynamic Compaction Techniques

Dynamic compaction is a technique used for in-situ densification of granular soil deposits by heavy impact.
