"AP Excavating installed a drinking post for our horses and replaced a water hydrant. Wonderful father and sons family business - great to work with them and their crew. I was impressed with the quality of work and their commitment to making sure they exceeded our expectations. I will be using them for our next projects: entry gate, trenching work and landscaping driveway island. Thank you AP Excavating!"

"Rich Che and the CNS Empire Landscape crew did fabulous improvements on our family home in Wheat Ridge. They corrected drainage on three sides of an addition so water flows away from the house instead of into the crawlspace; replaced 30 feet of exit pipe from the perimeter drain around the foundation of the addition; installed new sod; and removed weeds from landscaped rock areas in the front yard. The improvements look great. Shortly afterwards, I engaged an inspector to check the foundation. The inspector said he visits about 400 houses each year, and this drainage remediation is among the best he’s seen."

"Larry and his crew performed shoreline stabilization and erosion control services on the lake where we live. They also cleaned up the shoreline and installed special geotextile fabric before installing over 2 tons of riprap. The crew did an amazing job and finished way ahead of schedule. I am recommending this company to other neighbors and will happily use them for future work. I’ve attached before and after photos."

I couldn't believe how nice and fun his crew was they had my driveway installed in no time, actually a day early! I have no doubt its going to last for years to come. I would recommend these guys to anyone who needs an excavator!"

"Steve was so wonderful to work with. We needed someone to excavate and grade our side yard in preparation for laying gravel. He was very timely in getting us scheduled and his work was very well done. Overall, Steve was a clear communicator, gave a fair price, and took care to ensure we were happy with the results of his work. I would highly recommend him!"

Excavating questions, answered by experts

Septic drain lines (or leach lines) are typically buried between 18 and 36 inches underground, and should be at least 6 inches below the surface. These pipes are perforated and surrounded by filtering materials like sand or gravel. Burying the lines at this depth helps minimize odors and allows bacteria and other biological processes in the soil to effectively treat the wastewater. Burying lines too close to the surface can cause issues unless the soil is very compact and stable.

A crawl space can be as little as 42 inches below the grade of your house, but this is not always recommended in flood-prone areas. At a minimum, there must be at least 16 inches of clearance between the ground and the floor joists to access the space in an emergency.

Yes, you can excavate in the winter, but it might make the job harder. Frozen ground is harder to dig, and snow or ice can make the work site more hazardous. A contractor may need special equipment and techniques, such as ground-thawing methods, to break through frozen soil. Although winter excavation is possible, it may take longer and be more costly than excavating during warmer months.

Downspouts should be buried at least 5 to 10 feet away from your foundation. This can vary depending on your local building codes, soil type, and property slope. The main goal is to ensure water is directed away from your foundation.

Above ground pools are not buried in the ground. Typically, above ground pools are semi-permanent. One reason they’re more affordable is that you don’t have to dig for an inground pool and pour concrete or another material. However, you can choose to install a semi inground pool, which is a hybrid between the two.
