Coastal areas are exposed to waves, currents, tides, storm events and changing water levels. These conditions can cause erosion, scour and instability, which may affect shorelines and coastal infrastructure. Conventional protection systems such as concrete seawalls and rock revetments remain widely used, but they can require large quantities of materials, heavy equipment and careful foundation preparation.<\/p>\n

Geosynthetics can be used as part of coastal protection systems to provide filtration, separation, erosion and scour protection, reinforcement, or containment. Depending on the site conditions and design requirements, geotextiles, geotextile tubes<\/a>, geosynthetic sand containers and geogrids can complement or, in some applications, provide an alternative to conventional materials.<\/p>\n\r\n\t\t<\/div>\r\n\t<\/div>\r\n

Key Functions of Geosynthetics in Coastal Applications<\/h2>
<\/i><\/div><\/div>

Filtration and Drainage<\/h3><\/div>
Allows water to pass while retaining soil particles, helping to reduce soil loss and prevent internal erosion.<\/div> <\/div><\/div>
<\/i><\/div><\/div>

Containment<\/h3><\/div>
Contains sand, dredged material or other suitable fill within geotextile tubes or containers to form engineered structures.<\/div> <\/div><\/div>

Separation and Stabilization<\/h3><\/div>
Separates dissimilar materials and can improve the performance of foundation or working platforms over soft soils.<\/div> <\/div><\/div>

Erosion and Scour Protection<\/h3><\/div>
Helps protect soil surfaces and structure toes from erosion when used together with suitable armour or containment systems.<\/div> <\/div><\/div><\/div><\/div>

Geotextile tubes are large tubular containers made from high performance woven geotextiles. They are hydraulically filled with a suitable slurry, commonly sand and water or dredged material. During filling and dewatering, water passes through the geotextile while the solids are retained, forming a consolidated fill mass.<\/p>\n
