Retaining walls

What's included

Because the same crew does the excavation and grading, the wall goes in as part of the dirt work: cut the slope, set the rock, finish the grade.

Dorien and his team did a great job on a driveway/open area project. Super efficient. Had the land cleared and prepped in one day! Very impressive.

If you need excavation, demolition, or land clearing done right, look no further! Dorien and his team bring skill, precision, and a level of pride in their work that's hard to find these days. He always says he loves playing in the dirt, but the real magic is how he turns a messy job into a clean, professional result. Whether it's prepping a site for a new build or clearing out an overgrown lot, they handle it with craftsmanship and care. Highly recommend for anyone who wants the job done with expertise and a passion for the work!
