TechRevetment is an alternate and durable solution for erosion protection.
High-strength woven geotextile former is used to provide the shape and form. Essential components of the TechRevetment™ system are non-woven geotextiles, geotextile fabric form, and fine aggregate concrete. Depending upon the design requirements and specific application, liaison cables can be incorporated into the fabric form.

Benefits of the TechRevetment technology:
Underwater installation is one of the various advantages of the TechRevetment solution. This provides a unique advantage to the client where dewatering or constructing cofferdams is not possible such as canal bank protection and lining, river bank protection, abutment or pier protection under flowing water.
The erosion protection system consists of fine aggregate concrete and the layout is seamless and monolithic. With the use of concrete, there is no requirement for using river stones or stone quarrying, which is a major environmental concern nowadays.
TechRevetment is also flexible in nature and can adapt as per the soil contour of the bank slope or channel bed. The installation process is faster than the conventional concrete or boulder pitching and gabion laying. It delivers the durability and performance of concrete without the costly, time-consuming, and difficult installation process of a conventionally-formed concrete slope paving.

TechRevetment comes in several designs adapted to the site conditions:

• > Filter point: with the provision of filter points to release pore water pressure from the embankment and increase the stability of the system.
• > Uniform sections: with low coefficient of rugosity to minimize head losses, adapted to canal lining
• > Articulating blocks: with internal high-strength cable reinforcements in one or two directions, combine resistance to hydraulic forces and flexibility to adapt to the ground profile
• > Vegetated: with unfilled areas to allow vegetation growth, for ecological, aesthetically pleasing, and robust erosion protection

TechRevetment is appropriate for the following:

• + Protecting river banks or shorelines from wave and current actions
• + Scour prevention and scour repair
• + Controlling erosion along bridge abutments and piers in flowing rivers
• + River training works
• + Forming impermeable linings for containment ponds or canals
• + In complement to the TechRevetment form concrete mattresses, we will supply Terra Textile, NW geotextiles for the filter layer, and Terra Anchor soil anchors which may be required to provide additional resistance against sliding of the TechRevetment layer.
