""ABSOLUTELY SUPERB" - Ken and Rowen were contracted to install Round River Rock Stone along approximately 180 feet (both sides) of my driveway. Ken promptly answered my request for an estimate. The next day he arrived to view the job and was very thorough about understanding my expectations for the project, He offered advice and is very knowledgeable about how to do top quality work. After my reviewing other estimates my decision was to go with McAdams Excavating, Ken and Rowen arrived as promised and quickly began meticulous work. Material was excavated to provided a 3 inch depth of stone, landscape fabric was installed, finally the stone. The duo were meticulous in all facets of this project and it looks absolutely gorgeous!

Excavating FAQs, answered by experts

Yes, chipmunk holes may have two or more entrances. Chipmunks can create an entire network of burrows. Having multiple entrances makes it easier for them when trying to escape from a predator, such as a snake, or if an entrance collapses due to flooding. Each entrance leads to the nesting chamber underground, which is where the chipmunk spends the majority of its time sleeping.

Preparation involves site assessment, clearing debris, grading surfaces, and compacting soil to support stable construction.

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 perc test can take anywhere from one to eight hours to complete. The total time depends on factors like the amount of excavation required, the depth and width of the holes, and whether multiple test holes are needed. For a single hole, the process of filling it with water and monitoring the drainage rate usually takes less than an hour. Professionals can often complete the entire test in a single day. While it's possible to get results the same day, some companies may take a few days to provide the official report.

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.
