Just completed a difficult drainage project on my property. 300' of french drain varying in depth from 4 to almost 10' in depth. The drain was constructed to intercept groundwater flows and some surface runoff and eliminate seepage and occasional flooding in my basement. Mark used the right equipment, materials (pipe, fabric and washed crushed stone) and superior grade control methods. Most importantly he accomplished the job safely in spite of trench depth and stability issues. I would be very happy to hire Ace Excavating for future projects.
