"We had a complete yard, front and back, design and execution of the design. Work involved removal of original yard and over grown plantings and unwanted trees. That work was done with care but very thorough. Then the new design was brought to life and transformed our outdoor space and its enjoy ability. We continue to utilize Outdoor Aesthetics for ongoing work for spring and fall cleanup as well as refining our yard as we tweak the plantings to enrich enjoyment."

"Hired for tree removal, block wall upgrade, remove garden, install sod, tree removal and trimming of another tree. Excellent service, and fair pricing. They cleaned up after work was done even in the street where trucks for debris were stationed. Workers worked very hard and were very nice and did a great job. Mariano, the owner was willing to help out with things I forgot to mention at the bidding process and all work completed in the designated time. I would hire them again."

Excavating FAQs, answered by experts

Excavation and grading are both generally necessary for designing your foundation, and leveling the ground where your foundation will go. These steps can also prepare the area by removing vegetation and anything else that could interfere with your home’s foundation.

Trenches are typically 12 to 24 inches deep and 8 inches wide. However, the required depth depends on the specific project and local ordinances. For example, a French drain may need to be 18 inches deep, while a water pipe might require a depth of 24 inches and a drainage pipe 36 inches. Your city or county may have specific regulations, so it's wise to consult with an excavation professional to determine the correct depth for your project.

The best type of soil to build on is a mixture of sand and clay, known as loam soil. Loam soil has the best combination of these soil types to build a foundation on. The clay particles help with water retention, so it won’t erode like sandy soil might, and the sandy particles help with drainage, so you won’t see unsafe soil expansion or have an increased risk of leaks from water sitting against your foundation.

Trenching and boring are two distinct methods for installing underground utilities. Trenching involves digging a channel using equipment like an excavator, trencher, backhoe, or shovel. While it is a simpler process, it causes significant disruption to the surface, landscaping, and surrounding ecosystems.

Boring, also known as directional boring, is a less invasive alternative that uses a drill to create a tunnel for utility lines without disturbing the surface. This method is more precise and is ideal for installations that need to go underneath buildings, roads, or bodies of water. Although boring is less disruptive, it is generally more expensive than trenching.

The best method for digging a trench depends on the scope of the project. For a short, shallow trench (less than 2 feet deep) in light, soft soil, digging by hand may be sufficient. However, digging by hand is labor-intensive, so consider the effort required. A machine trencher is the better option for longer trenches (over 100 feet), deeper ones, or when dealing with difficult soil conditions, such as rocky or hard ground, or obstructions like tree roots. A machine can save significant time and energy in these situations.
