Tensar® uniaxial (RE) geogrids are the most advanced geosynthetic made for soil reinforcement, specifically developed for the construction of structures such as retaining walls, load bearing bridge abutments, steep slopes and slip repairs. Made from high-density polyethylene (HDPE) resins, the geogrids can carry high tensile loads applied in one direction (along the roll length) and provide superior load transfer from the soil to the geogrid with their open aperture structure that interlocks with fill material.
Tensar RE Uniaxial geogrids achieve their strength by punching and drawing a homogenous polymer sheet to provide a uniform, consistent product that does not require weaving, coating or welding to maintain the product’s integrity. This unique process provides superior junction strength, allowing high-strength connections to other rolls of geogrid or facing components, for example Keystone TW3.
Tensar RE Uniaxial geogrid is suitable for a wide range of applications from shallow slopes to vertical walls. It is one-of-kind as it can be joined using bodkins to reduce wastage on site and provide an efficient mechanical connector for concrete panel retaining walls.

WHY CHOOSE TENSAR RE UNIAXIAL?
- Designed to interlock with a wide range of fill materials with its long, slim apertures and integral junctions
- Versatility to connect with several different block systems, concrete panels and steel mesh panels to form a retaining wall and can also be used as a wraparound facing
- Highly oriented polymer structure to resist elongation (or creep) under sustained tensile loads
- Allows slopes of any angle to be constructed using a wide range of fills
- A fast, cost-effective way of building embankment and slip repairs that require a steep face angle
- Highly durable and robust with independently certified long-term strength properties; and a design life of 120 years
- Resistant to installation damage and chemical or biological long-term degradation
Available in six grades: RE510, RE520, RE540, RE560, RE570 and RE580.
Tensar RE Uniaxial geogrids are accredited by several independent government and other certifying agencies around the world. Manufactured in accordance with Quality and Environmental Management Systems which comply with the requirements of BS EN ISO 9001:2015 and BS EN ISO 14001:2015 respectively.
Tensar RE Uniaxial geogrids meet the New Zealand Transport (NZTA) clause 6.8.1 of the Bridge Manual 3rd edition.

APPLICATIONS
FUNCTION
Reinforcement
Geosynthetics provides additional strength to soils and aggregate. Used to reinforce steep slopes, and to stabilise road or rail construction over weak and variable soils. Enables embankments to be constructed over very soft foundations and to build slopes at steeper angles than would be possible with unreinforced soil. Geosynthetics (or geogrids) are also used to bridge over voids that may develop below load bearing granular layers (roads and railways) or below cover systems in landfill applications.
Retaining
Geosynthetic or geogrid acts to support soil laterally so that the structure can be retained at different levels on the two sides. Retain (holds back) any material (usually earth) and prevents it from sliding or eroding away. Gravity retaining and reinforced soil retaining walls are designed to resist the material pressure of the material that it is holding back.
