The TensarTech Marine wall system incorporates substantial concrete facing units capable of withstanding direct wave attack. The face units may, if necessary be pre-cast on site with the starter lengths of geogrid cast into the rear face of the units. Once installation gets underway, the main length of geogrid is then simply connected to the starter using a full strength bodkin joint.
River training walls are commonly built using TensarTech Modular Block Wall Systems. Incorporating precast concrete modular (segmental) facing blocks the system may be installed without crane lifts or propping and the geogrids are securely attached to the face using a high efficiency polymer connector.
For enhanced erosion protection in areas prone to wave run-up or occasional high velocity flows Tensar Mat is a cost-effective non biodegradable permanent layer to help natural vegetation prevent soil erosion.
Compared with traditional reinforced concrete structures, TensarTech Wall Systems offer you a number of benefits:
No propping: the unique modular block system can be simply built without the need for propping and in many cases without crane lifts
No concrete curing time on site: the dry jointed precast facings units require no curing and lend themselves to inter-tidal working. This also reduces the pollution risk from concrete contamination of watercourses.
Easy installation: often no specialist skills are needed
Reduce environmental impact: by using site-won or reclaimed material as fill, construction CO2 emissions can be reduced
Cut construction costs: with easy, rapid construction and the use of site-won materials, costs and time can be cut by up to half
Little or no maintenance: the systems have a design life of up to 120 years with minimal maintenance
Where soil erosion may be a problem, Tensar Mat can be the ideal choice:
Natural erosion protection: stabilising the surface while vegetation becomes established, then reinforces and enhances the root system in the long-term
