**2.1 Sampling**

All samples used came from polyolefin geocells available in the Colombian market. The sampling was conducted randomly from a bank of specimens supplied by the manufacturer. For the high-density polyethylene (HDPE) geocells, its polymer contents are not mentioned in this document, since it is known as high-density polyethylene in all the state of the art. While for the Neoloy® Geocell, no typology is obtained since its raw material is patented and there is no information about its polymer composition.

For the first type of HDPE polyolefin geocells from Provider 1, the properties are shown in **Table 1**.

For the second type of HDPE polyolefin geocells from Provider 2, the properties are shown in **Table 2**.

For the third type of polyolefin geocell from Neoloy® of Provider 3, the properties shown in **Table 3** are available, for categories A, C, and D.
