"Humberto is a very creative problem solver! Personable and definitely interested in customer satisfaction, so spends time understanding the full scope of the problem. The problem was the subterranean north wall of the sanctuary of First Presbyterian Church in Vallejo that was far from being waterproof, especially with the rains last winter. Castaneda dug out the soil next to the wall, pressure washed it and applied two coats of DryLok and then a layer of Henryâ s waterproofing. Then Humberto installed a French drain and then a big pipe to route the water off of five downspouts. To get the correct drainage slope, more excavating needed to be done than anticipated. Removed five landscaped trees and lots of concrete that was in the way of the drains which were to be routed under city sidewalks."

"I am incredibly pleased with this company. The entire crew were 100% professional. The owner of the company took time to answer my homeowner questions as they came up. He was very patient and thorough. All the men on the job worked incredibly hard and stayed on task throughout the project. They installed the French drain, installed a washout and removed an old deck all in a weekend. I would most certainly recommend them."

"I cannot say enough about how good this experience with John Mountain/Mountain Engineering has been. They said it would be 3 weeks; anti was. The work was painstakingly done, including a French drain behind the wall. And they replaced the plants that were destroyed during the process, which was an unexpected bonus."

"Our Realtor referred us to Ivanscaping, and we are thrilled with the results from Ivan and his hard-working team. We needed a yard makeover to help with the sale of our home, completely replacing a large, unhealthy front yard with a new design to enhance the curb appeal of our property. Ivan met with us and helped plan a new landscape that would minimize the grass area for easier watering, and create a new perimeter featuring drought-resistent plants. We found Ivan to be very experienced, patient, and thoughtful with his approach, supplying multiple samples of stone and mulch for our review, and offering his expert advice on how to achieve our goals. He helped rough in the new design by providing both a digital sketch and walking us through the yard to mark specific locations for the new features so we knew exactly what to expect. Ivan recommended some specific plants and grass for us based on photos we supplied, and took care of all the details—making the project very simple and"

"This was basically a demolition project. I had to have a 75 year old concrete circular retaining wall buried in the center of my asphalt driveway that had to be removed so that we could plant an oak tree. The wall was approximately 25 feet in circumference, 4 feet high and the concrete at least 3 inches thick. The bottom foot and half of the wall was covered with earth that had to be dug out by hand. Jose accomplished this extremely difficult job in a day and a half working right along side his helpers. He was able break up and haul away the concrete and did a great job cleaning up the site. He is courteous, professional and his rates are extremely fair. I would definitely recommend him for any job."

Excavating questions, 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. 

Directional drilling is complex and requires training to use the advanced machinery. It can be challenging to monitor the position of the drill since there’s no direct line of sight. Directional drilling can also be more expensive with a cost of $10 to $30 per linear foot compared to $5 to $12 per linear foot for trenching. 

As a general rule, the protected area should be about 1½ times as wide as the canopy of the tree’s leaves. This digging measurement can vary by tree species and the age of the tree. Of course, that can be a lot of fencing for larger trees, which is why our first step is about making difficult decisions on which trees to save.

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.

A mini excavator can dig between 5 and 11 feet deep, depending on the type and size of the mini excavator. Mini hydraulic excavators are more powerful and can reach deeper into the earth, but electric models have a more limited range. Mini excavators over two tons in size are also more powerful and able to dig as deep as 11 feet.
