"Called for a estimate to repair a private rd with two houses on it. He came out in a timely matter and took the time to share what would be the best solution based on his experience. We hired him to build up and grate the driveway/private rd. He showed up during the time frame he said he would and built up and graded the driveway/private rd as well as pitched it so that water wouldnâ t pool. He is just a great guy with a ton of experience to help the customer make the best informed decision. Will use Faulkner for any needs we have in the future hands down."

Excavating questions, answered by experts

To locate an underground downspout, you should start by identifying where the above ground gutter drains. Look for an entry point, such as a pipe or elbow leading into the ground. Follow the surface path for signs like depressions, landscaping disruptions, or wet areas after rain. You can use a metal detector or plumber’s snake to trace the pipe underground. For deeper pipes, a professional locator tool or camera inspection may be necessary. Visual markers or utility maps can also guide the search.

Depending on the severity of the freeze and the method used, thawing frozen underground pipes can take anywhere from 30 minutes to several hours. Applying heat directly to the pipe using heat tape, infrared lamps, or hot water jetting can speed up the process. However, patience and careful monitoring are key to avoiding pipe damage.

Yes, you can install a trench drain if you already have concrete in your yard or garden. While it can complicate some aspects of the job and slightly run up the cost, it is doable. Residential trench drains can be easily retrofitted to outdoor areas with concrete without having to remove excessive amounts of your patio, pool area, or decorative walkways.

Professional installers often include a deep layer of crushed gravel under permeable pavers to allow more runoff to soak through into the soil below. Many installations will include multiple layers of gravel, with coarser aggregate at the base and finer aggregate that sits on top of that bottom layer. Above the gravel, you’ll often find coarse sand that helps reduce paver shifting over time. Some permeable paver designs include a water collection system set into the gravel layer to route runoff to a safe area for disposal.

A trench that is less than 5 feet deep often doesn't require a protective system. Most residential trenches will not go this deep (the typical residential drainage trench is just 18 inches deep). In the event that an excavator needs to dig more than 5 feet beneath the surface, a protective system is required unless the excavation is in entirely stable rock.
