Basalt Man Rock is a darker gray color rock ranging from basketball sized rocks to 5,000 pound, 5ft wide rocks. We can deliver these boulders either in our dump trucks or with our specialty grapple truck that has the ability to place and rotate the rock. It is important to keep in mind that if you have this rock delivered via our dump trucks, the rocks will continue to break down through the loading and unloading process. You will end up with lots of crushed material and dustings along with the bigger boulders. If you would like to hand-pick boulders from our in-yard selection, we would then recommend delivery via our grapple truck to ensure the look that you wanted.
