Grading and Leveling Your Landscape

Grading and Leveling Your Landscape

grading and levelingGrading and leveling your lawns, landscaping and gardens will allow you to enjoy your yard and protect the structural integrity of your home. Planning the grade of your landscape features is the first step toward easy maintenance and a successful lawn or garden.

When you are planning or seeding your lawn, keep in mind that a gentle slope is recommended for at least the first ten feet away from the foundation of your house. This slope should be a minimum of one inch per ten feet. That same pitch is recommended for drainage on brick, stone or concrete patios. If you do not have a professional slope measuring instrument, an inexpensive string level will work for most projects.

If you cannot bring your lawn to a level grade or if it slopes toward your house, you may need to construct a small ditch to direct water away from the foundation. This ditch should be seeded with grass if possible to maintain the aesthetics of your lawn and to prevent erosion.

If your landscaping includes flower beds and garden areas, you will also need to give careful consideration to the grading and leveling of these features. Depending upon your plan for watering – drip systems, sprinkling or ditch irrigation – you will want to use grading and leveling to design your beds and gardens to make the best use of the water you apply.

Properly grading and leveling your landscape will pay off for years to come.

Excavation Methods

Excavation Methods

When a contractor approaches an excavation site, he takes several things into account. What is being excavated is foremost, followed by examination procedure and possible rainfall. With these factors in mind, the contractor may employ one or more of the following methods.For large areas that will be completely excavated, horizontal excavation (also known as open area excavation) will be used. It strips away strata layer by layer, exposing the entirety of the area little by little to be broken up and examined by grid square.For mounds or areas where there are multiple layers to compare, vertical excavation involves digging a trench through a site. Vertical excavation allows for easy comparison of strata layers and examination of mounds without destroying them. A laser level is used to take site measurements before digging. Some areas of horizontal excavation are combined with vertical excavation if there are deep layers of occupancy to examine. When the general layout of a site is known, keyhole excavation can be used to dig trenches only into areas of interest, leaving the rest of the site undisturbed.

Step trenching is a variation of vertical excavation for very deep sites. Stair steps are carved into the trench sides for easy access.
For vertical excavation areas possibly prone to water logging, cofferdams are used. The walls of cofferdams are cut to prevent sediment cave-ins. Contact RealTree, Inc for your next excavation project.
