StrataGrid® Geogrid
StrataGrid® is a high-performance polyester soil reinforcement grid.
This geogrid is manufactured from polyester yarns that have a high molecular weight and excellent tensile strength. These yarns are then knitted into a dimensionally stable network of apertures to form the geometric grid shape which offers tensile reinforcement to the soil.
StrataGrid is coated with a black bituminous saturation coating to provide further chemical and mechanical benefits that enhance its durability in harsh environments.
High strength polyester geogrids are ideally suited to retaining walls, steepened slopes, and embankments subjected to long term creep loads. PET has superior long-term creep resistance compared with an HDPE or polypropylene polymer.
StrataGrid is very easy to install and available in wide rolls minimising wastage and labour during installation.
Cirtex® can offer documentation for connection capacity between StrataGrid and a range of segmental block systems available within Australia and New Zealand.
StrataGrid® is a registered Trademark of Glen Raven, Inc. Registered in the United States.
Frequently Asked Questions
What is StrataGrid?
A uniaxial high-strength polyester geogrid.
What are the common uses for StrataGrid?
Reinforcing slopes, walls and embankments.
What are the advantages for using StrataGrid?
- 3.8m wide rolls – no memory so they won’t roll up.
- The High-Strength Polyester StrataGrid has superior creep resistance.
- Cirtex can efficiently integrate it with MSE wall designs.
- We can provide many successful case studies.
What grades are available?
40kN/m up to 400kN/m.
What is the difference between StrataGrid and DuraGrid?
StrataGrid is a PET grid designed for walls slopes and embankments whereas DuraGrid is a PP grid designed for pavements and foundations. The two products are designed for very distinct and different purposes therefore in most applications, they cannot be switched or substituted.
Is StrataGrid UV resistant?
StrataGrid is made from polyester which has excellent resistance to UV light and it is also coated providing further protection from environmental effects. However, all polymeric products which are required to provide 100-year design life should be protected from prolonged exposure to sunlight.
