Earthworks conducted during site preparation and landscaping can significantly alter soil composition, hydrology, and vegetative cover, as well as introduce non-biodegradable erosion control and landscaping fabrics. In this division we look at less disruptive foundation options and biodegradable erosion control products.
Conventional foundation excavation can disturb plantings and soil, and cause sediment runoff and erosion, especially in fragile environments, such as boardwalks and decking in wetlands. Foundation options that reduce the need for excavation have a lower environmental impact, both onsite and globally, requiring less energy for transport of excavated material and fill. These foundation types often reduce the need for steel and concrete.
Natural-fiber biodegradable erosion control products perform well, and also serve as mulch to aid in seedling establishment as the site is landscaped.
