Abstract
A method of maintaining soil strength and stability involves positioning a sheet of soil stabilization and strengthening material on a selected area where the strengthening and stabilization of the soil is desired. The sheet of soil stabilization and strengthening material includes a fabric layer that forms a base of the soil stabilization and strengthening material. The lower surface of the fabric layer is positioned against and engages the selected area. A moisture impervious layer is coupled to the upper surface of the fabric layer. A particulate aggregate material is embedded in the moisture impervious layer.

A method of maintaining soil strength and stability comprising:
- positioning a sheet of soil stabilization and strengthening material on a selected area where stability and strength of soil is desired, the sheet of soil stabilization and strengthening material comprising:
- a fabric layer that forms a base of the soil stabilization and strengthening material, the lower surface of the fabric layer being positioned against and engaging the selected area;
- a moisture impervious layer coupled to the upper surface of the fabric layer;
- a particulate aggregate material embedded in the moisture impervious layer;
- a second moisture impervious layer positioned over and coupled to the upper surface the moisture impervious layer having the particulate aggregate material embedded therein;
- and
- a second particulate aggregate material embedded in the second moisture impervious layer, the particulate aggregate material embedded in the moisture impervious layer having an average particle size that is from >1 to 5 times larger than the average particle size of the second particulate aggregate material, and wherein
- the particulate aggregate material embedded in the moisture impervious layer having an average particle size of from 2 mm to 4 mm and wherein the average particle size of the second particulate aggregate material is from 1 mm to 2 mm.

A method of maintaining soil strength and stability comprising:
- positioning a sheet of soil stabilization and strengthening material on a selected area where stability and strength of soil is desired, the sheet of soil stabilization and strengthening material having a width of from 3 feet to 20 feet and a length of from 10 feet to 300 feet, the sheet of soil stabilization and strengthening material comprising:
- a geotextile fabric layer that is at least one of a woven, non-woven, needle punched, and heat bonded fabric material and is permeable to moisture and forms a base of the soil stabilization and strengthening material, the lower surface of the fabric layer being positioned against and engaging the selected area, the fabric layer having a thickness of from 0.5 mm to 7.0 mm, a weight of from 3 oz/yd2 to 50 oz/yd2 as measured according to ASTM D5261, and a grab tensile strength of from 50 lbs to 1000 lbs, as measured according to ASTM D4632;
- a moisture impervious layer that is a rubber and/or elastomeric material coupled to the upper surface of the fabric layer, the moisture impervious layer having a thickness of from 0.5 mm to 7.0 mm and a weight of from 3 oz/yd2 to 250 oz/yd2;
- and
- a particulate aggregate material embedded in the moisture impervious layer, the particulate aggregate material having an average particle size of from 2 mm to 4 mm and covering from 5% to 99% of the surface of the moisture impervious layer, the weight of the particulate aggregate material of the sheet of soil stabilization and strengthening material being from 5 oz/yd2 to 500 oz/yd2;
- a second moisture impervious layer positioned over and coupled to the upper surface the moisture impervious layer having the particulate aggregate material embedded therein;
- and
- a second particulate aggregate material embedded in the second moisture impervious layer, the particulate aggregate material embedded in the moisture impervious layer having an average particle size that is >1 to 5 times larger than the average particle size of the second particulate aggregate material, the average particle size of the second particulate aggregate material being from 1 mm to 2 mm.
