required densities have been achieved. These test sections
are typically evaluated using either standard penetration
tests or preferably cone penetrometer tests.
As the fines content in soil (percentage of silts and clays)
reads beyond 15 per cent, the effective densification depth
tends to be reduced. Consideration should be given to test
sections for soil and fill with higher fines to verify the suit-ability.
Often, the cost savings available to the project are
considerable and worth considering a test section or minor
excavation of pockets of unsuitable soils that are identified
during RIC work.
The RIC process uses repeated and controlled impact
energy to densify soils in place. The vibrations generated by
this impact energy are typically below the City of Toronto
By-law requirements at a distance of roughly eight to 10
metres (25 to 30 feet). When working closer than this to
receptors, mitigating measures can be undertaken to reduce
vibration travel.
It is not hard to imagine the cost and schedule benefits
RIC can deliver over a “remove it” approach on your project.
Advantages of the RIC system include the following:
1. Avoid shoring systems – work can be completed at or near
the property line
2. Minimize or eliminate dewatering – footings founded
high on improved soils limits excavation
3. Rapid installation – work is completed at up to 800 m2 a
day from existing grades
4. Schedule savings – avoiding excavation eliminates chal-lenges
caused by weather events
5. Cost certainty – the RIC process is typically completed by
GeoSolv as a design-build lump sum
When evaluating the support for your next project,
remember that there are a number of options you can con-sider.
To ensure you are maximizing the value of your project,
remember to evaluate all of your options – remove it, go
through it… or improve it.

TECHNICAL
This system has been shown
to be successful in sandy
soils, densifying loose-fill
soils up to six metres
deep or more, without the
need for soil handling.
