"Ryan and his employees proved to be an exceptional landscaper team. Our project involved digging up old sod, backfilling with new soil, moving boulders, adding cedar chips as a topcoat, adding river rock edging to a driveway, and making two paths and a bench pad with decomposed granite. We had an initial plan, but Ryan suggested changes that greatly improved the result. The results are better than expectations. Plantings will be later. He was able to do the work sooner than expected and was very good at communicating via text. We strongly recommend Rimrock."

"They contacted us immediately and got the permit very fast. It took 3 days from start to finish. I would recommend this company for any excavating needed as well as installing a new septic system. They care about doing the best work for you and it shows. Fantastic company!"

"What a great find CO Excavation was! Bill and his crew were professional and friendly. They showed up on time with all the right equipment, worked diligently and quickly, did a great job, and priced their work reasonably. They removed some large pine trees, moved/placed large boulders, excavated a circle driveway, built quite a few large berms, sculpted a swale, installed drainage, and leveled our yard for landscaping."

"Cavallero Earthworks came to our home when he said he would be here. He sat and listened as we explained our problem. He took charge: filled out forms, contacted the proper county agency, gave us a bid amount and my husband and I just sat there in the kitchen after he left awestruck by the proficiency and speed in which Ben handled everything. He took time out of his busy schedule and was in constant contact with us, keeping us informed of where we were in the process. He stayed focussed on the task and completed it quickly and efficiently. Professional, good communicator, proficient on the equipment, knowledgeable in his line of business, and just a really nice person! My husband and I appreciate Cavallaro Eartworks and wish them the best."

"We were very pleased with both the quality of the work and the experience of working with Parker. Parker was a breath of fresh air compared to the excavators we talked to before trying Angi. He spent time with us looking at the ruts in our 30-year old driveway, discussed solutions and options, and gave us a fair, detailed quote so we knew exactly what to expect. He communicated with us every step of the way, so scheduling and knowing what to expect were a breeze. Parker and his crew arrived exactly when they said they would. They worked hard all day to strip the driveway and change the slope, so water drains down the hillside rather than pooling. They put down new rock, graded it, and then rolled it, so in the words of my husband, “Our gravel driveway is as smooth as asphalt.” Our family, regular visitors, and delivery drivers are very pleased with the end result. It was a pleasure doing business with Parker, and we are very glad we found him."

Excavating FAQs, answered by experts

How deep your septic system needs to be into the ground depends on several factors. In extremely cold environments, the tank needs to rest below the maximum frost line, which can be up to six or eight feet deep. The standard burying depth for most systems is between a few inches and four feet below ground level. Depth can also depend on the slope of the landscaping and other property variables. 

The best way to protect tree roots is to avoid the roots entirely by excavating outside the root radius of the tree. For nearby projects, it’s a good idea to construct a temporary retaining wall. But that’s not always possible, depending on the project and the root system. In these cases, consider using alternative equipment like an auger to tunnel under the ground.

Remember, tree roots can damage nearby cement foundations as they grow. If a tree is close enough to interfere with large excavations, it may be better to remove the tree than risk future problems.

Most residential basements are 8 to 10 feet deep. You can dig deeper depending on building codes, but it does become more difficult. You’ll likely need to install stronger foundation walls and additional supports to handle the increased load. Depending on the water table, you may also need a water management system. Clay soil can support a deeper foundation than sandy soil. A structural engineer will be able to tell you the maximum, feasible depth.

The physical constraints of hand-drilling a well limit the depth you can achieve. Manually digging with picks and shovels may only lead to shallow wells of up to 60 feet in depth. To reach greater depths, you need more specialized equipment. The diameter of your well and the tools you’re using will determine how far down you can dig.

Excavation is priced in cubic yards, so you’ll need to find the volume of the area in order to calculate costs. Multiply the length, width, and proposed depth of your excavation site, then convert it into yards to get the volume. Multiply this figure by the price per cubic yard.

Most homeowners can measure by hand to get a rough estimate, even if it’s tedious. You may want to pull out a tape measure or use a string to help mark the area.
