Polymer: Polypropylene

Resistance to Ultra-Violet Light: A high level of resistance to UV light is given to E'GRID by the incorporation of 2% of weathering grade carbon black, well dispersed in the polymer matrix (1). These products may be used for many years in exposed conditions.

Chemical and Biological Resistance:

E'GRID bi-axial geogrids are manufactured from polypropylene which is unaffected by all chemicals, including acids, alkalis and salts, normally found in soils. Also, it is not a nutrient, therefore these products are not affected by micro-organisms in the soil.

1. Measured in accordance with ISO 10319 at 20 +/- 2 C; calculated as the 95% lower confidence limit in accordance with ISO 2602 1980 (BS 2846 Part 2 1981).
2. Calculated from data obtained in accordance with ISO 13431; creep strength predicted for 120 years design life, taking account of prediction and production.
3. For in-soil design temperatures as shown.
4. In accordance with BS2782 Part 4, Method 452B, 1993.

Quality Control test certificates will be issued according to customer's requirements.

Polymer: High Density Polyethylene

Resistance to Ultra-Violet Light: A high level of resistance to UV light is given to E'GRID by the incorporation of 2% of weathering grade carbon black, well dispersed in the polymer matrix (4). These products may be used for many years in exposed conditions.

Creep Performance:

A good creep performance under sustained loading is essential for the use of geogrids in critical structures such as walls, abutments and steep embankments. Qingdao Etsong Geogrids Co., Ltd. maintains constant Creep testing programmes in its laboratories and works closely with National and International experts in the performance of geogrids to ensure that its products meet the strictest demands in all markets.

Chemical and Biological Resistance:

E'GRID uni-axial geogrids are manufactured from high density polyethylene which is unaffected by all chemicals, including acids, alkalis and salts, normally found in soils. Also, it is not a nutrient, therefore these products are not affected by micro-organisms in the soil.
