Innovation
Controlled Modulus Columns or concrete inclusions are installed in areas of mucky or unstable soils to prevent a roadbed from settling. A drilling rig bores a hole on the down stroke from a large excavator type machine, then on the upstroke of the rig - concrete is injected uniformly into the bore hole creating a solid footing for roadbeds that does not settle over time. Our project used 736 CMC's to achieve roadbed stability.
Benefit and Implementation
CHEAPER, FASTER, and BETTER than wood pilings, or surcharging a mucky area over a long period of time. No settlement time is needed to wait for peat to compress.
