Specialty Excavator Attachments

	PC1250 with Extended Boom and Stick, Depth Capacity 85 ft. (25m). This extended boom and stick fits on either a PC1250 or PC1100. Here the excavator is seen on a project near Marysville, CA on project to stabilize flood control levees.
Komatsu PC 1100 with Extended Stick, Depth Capacity 72 ft. (21m).. The same unit as shown above can be more conveniently mounted with the extended stick only on a stock boom for projects where the depth requirements are not so extreme. This unit is working on creating a slurry wall groundwater barrier around a man-made lake near Greely CO.
	Komatsu PC 800 with Extended Boom and Stick, Depth Capacity 65 ft. (19m). This unit can modify a PC800 or PC750. The unit shown is working on a hazardous waste containment project near Delaware City, DE.
Komatsu PC 750 with Extended Stick, Depth Capacity 53 ft. With the stick from the above combo mounted on the standard long boom, a lesser depth can be attained, but with a simpler set-up on site. This unit is working on a slurry cut-off wall that is acting as a groundwater barrier on a Superfund site in Aurora, CO.
	Special Slurry Excavation Buckets Designed for Severe Duty and Narrow Width. Slurry walls are frequently keyed into hard materials such as weathered rock, glacial till, or stiff clays. Using buckets like these that are designed for maximum penetration in hard materials assure that the key-in required for a secure groundwater containment is attained. These buckets were used to penetrate shale bedrock on a site near Denver, CO.
Slurry Clamshell Bucket for Deep Excavations or Tight Quarters. At this site in Delaware City, DE, the Soil Bentonite slurry wall penetrated to depths in excess of 90 ft. (28m) and it also crossed under some active rail lines. The rail lines were closed for a few days while the clam excavated under and between the lines and the wall was backfilled to complete the slurry cut-off wall.
	Heavy Duty Slurry Clamshell digging to Depths of 165 ft. (50m) . Heavy Duty clamshell bucket digging to depth up to 165 ft (50m). This project was one of several in northern Alberta, Canada.
Trenching Tools . Geo-Solutions has special trenching tools for controlling excavation and backfill under slurry conditions. Tools such as end stops, fishing hooks, air-lifts, tremies, and chisels are generally in stock.

The excavation equipment built and owned by Geo-Solutions permits the efficient construction of slurry walls of all dimensions.
