Both large and small land renovation projects often require the services of an excavator. In this post we’ll go through the process of a typical landscaping project such as a patio, pool, or driveway installation, and show you when excavating requires contractors to collaborate during excavation in Hollis, NH.

Demolition and Debris Removal
Site preparation literally sets the foundation for successful landscaping projects. Site preparation can involve demolition and debris removal. If your project requires the removal of dead trees, boulders, old pools, old patios, sheds, or an old driveway, your excavator will collaborate with landscape designers and landscaping contractors to ensure that no desirable landscape elements are disrupted or destroyed. This includes trees, landscape boulders, and existing hardscapes.
The excavator may also need to consult with utility companies and contractors who will be installing underground utilities including natural gas, electric, and water.
Grading and Water/Soil Management
Grading is an essential part of preventing erosion and ensuring the structural integrity of heavy hardscape elements like patios, outdoor fireplaces, or driveways. But, grading is also important for shaping the land to create a pleasing landscape and accommodate the desired hardscapes.
An excavator may need to work with engineers to discuss soil conditions and drainage challenges, and coordinate excavation for retaining walls or ditches.
The foundation of a retaining wall needs to be deep and wide enough to give the wall the strength to support the immense pressure of soil and water behind the wall. The area behind a retaining wall must be excavated as well.
Whether the landscape is being renovated or the project is from the ground up (new construction), soil and water management is a top priority to ensure a successful outcome and to prevent future damage from soil movement or drainage problems.
Patio and Stair Installation
Patios are heavy, and require a solid footing to prevent movement that could cause cracking or other damage to the pavers. An excavator will work with the patio installer to determine how deep to excavate under the patio so that enough substrate can be added under the patio. Many residential walkways don’t need extensive excavation using machinery (their bases can be excavated by hand); but the area that will be under stairs dug into the slope may need excavation.
Pool and Pond Installation
An excavator will need to work with an engineer and the pool installer in order to ensure that the immense pressure from the surrounding soil does not damage the pool after it is installed. Difficult situations like underground utilities, bedrock, and the presence of groundwater will need to be addressed before the pool can be installed.
New Utilities
Aside from utility companies, an excavator will need to work with electricians, plumbers and other professionals who will be running wire and pipe to the site. Trenches will need to be dug, often in close proximity to the home, so it’s important for the excavator to work with the utility installers to ensure the correct depth and location of trenches.
Driveway and Parking Area Installation
Driveways need solid support. A deep base will allow a solid-surface or paver driveway to withstand the pressures of vehicles. The driveway must also slope away from the home or garage to prevent water from flowing toward the structures. The excavator will work alongside the designer and driveway installer to ensure a long-lasting and durable driveway.
