Earthwork Reservoirs, Dams, Canals, and Shoreline
Excavation and embankment to install or repair reservoirs, low-head dams, canals, and shorelines. Installation of artificial impoundments or repairs to existing caused by settlement seeps, slips or slides from erosion. Dredging sediment and armoring banks.
Slope or Bank Stabilization and landslide repair
Mass movements for slope failure can be caused by the increase in shear stress, such as loading, lateral pressure, and transient forces. Alternatively, shear strength may be decreased by weathering, changes in pore water pressure, and organic material on slopes of earth and rock-fill dams, slopes of other types of embankments, excavated slopes, and natural slopes in soil and soft rock.
Stabilization techniques vary depending on the site and many techniques can be used in tandem to achieve the desired stability. Techniques include, but are not limited to the following; Retaining Walls, Geo-web, turf reinforcement matting, gabion baskets, vegetation, plantings, geotextiles, coir logs, compost filter socks, embankment compaction, large stone or rip rap.
