We have an extensive background in surveying marinas in coastal and freshwater environments. We use hydrographic and land survey methods to determine the conditions of marinas and the sub-bottom terrain. We also offer results and recommendations for marinas for dredging and engineering. During dredging processes we work closely with the client and offer readily available survey data and maps throughout the process. We also offer sediment sampling for heavy metals and pollutants which can build up in marinas and channels.
