Silt & Sand Removal Services

Dredging sand can provide the perfect material for creating new beaches or rejuvinating existing beaches for just the cost of dredging versus having materials shipped to a location. Many times the spoils are pristine material that just needs to be relocated from a sandbar that is blocking a marina or an area that needs to be deepened to allow boat and ship entry. A growing method used to collect these spoils, especially for clients wanting to reuse the spoils is by use of GeoTextile Tubes. With this method, Southern Dredging & Marine would pumped the discharged materials from dredging directly into GeoTextile Tubes or Bags. After a short period of dewatering and evaporation, the materials can then be trucked to the location needing new sand.

Many projects call for a two pronged design of dredging an area to reach a specific maximum low tide depth for navigational purposes while at the same time creating new land out of wet areas. We can help design a methodology that will best suit your engineering plans to both dredge and create the new land. It is cost effective and can be performed according to your engineering drawings or feasibiltiy studies. Contact our office to learn more about use of dredging spoils to enhance your property.

Capital dredging is used for new or improved structures such as a harbour basin, or to gain a deeper navigation channel, create a lake, or new reclaimed land for industrial or residential purposes such as a beach. Capital Dredging includes relocating of large quantities of sediment or soil, non-repetitive dredging activity, soil that is compact, undisturbed soil layers, usually fairly free of contaminated materials and signs of significant layer thickness

Maintenance dredging means the repetive task of removing of silt, sediment and rock from existing channel, which generally occurs naturally, in order to maintain the design depth of navigation channels and ports. Maintenance of navigation depths is often necessary in ports. The main characteristics of maintenance dredging projects are that quantities of material will vary, ground is soft and not compacted, content could have contaminants, made up of thin layers of material, usually found in navigation channels and harbours, dredging needs to be repeated periodically
