Our specialty is hillside excavation utilizing the amazing Walking Excavator. This machine has the capability to work on steep slopes, as well as in 6 ½ feet of water. It is an environmentally friendly machine and perfectly suited for erosion control in creeks and rivers, as it can perform its tasks while incurring the least amount of damage. You don’t need roads to go where this machine can go. It can climb steep slopes without destroying everything to get to the job site. Though this machine is spectacular on uneven terrain, it also performs superbly on the easier jobs as well.
