"I would very highly recommend Sola de Vega. They removed our old grass and some soil, sprayed the area with an herbicide to prevent unwanted grasses from returning, installed a gopher/mole guard, replaced the sprinkler heads, and installed new topsoil and sod. Saul was very quick to respond to our request for a bid and was very reasonable in his estimate and final costs for the project. I can't speak highly enough to characterize his professionalism, rapid follow-up to our questions and concerns, and great communication and friendly demeanor. The project was completed on time, including installation and clean-up, and the results were beautiful."

Here at MP Excavating and Engineering we are a full service licensed excavation and general ground work contractor. No projects is out of our wheelhouse and we pride ourselves on keeping all of our jobs running smoothly and under budget. Call now for a free estimate.

"Ultimately happy with the end result and fair price for our 30ft sewer lateral replacement. Miguel was professional, friendly, and hardworking. However, communication was a bit spotty and we had follow up many times (I understand this is the busy season, though). Also, it was unclear if we were supposed to call 811; we assumed he would, but didn't, and this was an issue as the water line was hit during construction and the city had to come to shut it off on the whole street. It was handled quickly, but would have been avoidable. The project ended up taking much more time than expected, but it was completed in a day, as promised. I would recommend him, but you should be diligent and responsible yourself to make sure all the right steps are being taken."

Excavating questions, answered by experts

In the United States, a depth of 36 inches (three feet) for underground water lines is the accepted industry standard. This depth varies from location to location based on local conditions. In areas with colder winters, they may be buried deeper to prevent frozen well water pipes : This is usually at least six inches below the frost level. The International Plumbing Code calls for a minimum of 12 inches below grade.

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.

There are several different factors that influence how long it takes to excavate. For a foundation, it could take anywhere from three days to three weeks. It can take even longer if you face weather-related delays or an inaccessible site that’s riddled with boulders and rough terrain. It may also take longer if you have clay soil, which is more difficult to 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.

Call 811 to locate and mark the gas lines at least three days before digging. In many areas, you can dig within 18 inches of the lines, though in some locations, the distance may be further. Check local regulations, as you may need a utility company representative onsite when digging. Document your calls to 811 and precautions taken to avoid gas lines. A homeowner can be held liable for hitting a gas line in some cases, but contacting the proper authorities and following all guidelines can offer protection.
