GB standard Geocell uses recycled HDPE plastic, the seam peel strength is 10KN/m, and tensile strength is 18KN/m. Due to it is used recycled material, it only tests strength, not test more values. The quality is a little lower than the ASTM standard, but the price is more competitive. Due to the price being good, we sell very large quantity to customers in Vietnam, Indonesia, Thailand, and the Philippines.

ASTM standard Geocell uses virgin HDPE material to produce, the seam peel strength is 14.2KN/m, and tensile strength is 22KN/m. This type of Geocell not only tests strength but also tests other values. Like Environmental stress crack resistance and OIT oxidation induction time. The quality is very good, so the price is a little higher than the GB standard. Most sell in the USA, Europe, Germany, and Australia.
