HDPE Protection
 Wallbarn stocks a full & comprehensive range of HDPE protection.
A linear polymer, High Density Polyethylene protection (HDPE protection) is prepared from ethylene by a catalytic process. The absence of branching results in a more closely packed structure with a higher density & somewhat higher chemical resistance than LDPE. HDPE protection proves to be harder & more opaque & it can withstand rather higher temperatures (120° Celsius for short periods, 110° Celsius continuously). HDPE protection lends itself particularly well to blow moulding.
HDPE protection creates a new composite entity that possesses enhanced mechanical & geotechnical properties when infilled with compacted soil.
When the soil contained within the HDPE protection is subjected to pressure, it causes lateral stresses on perimeter cell walls. The 3D zone of confinement reduces the lateral movement of soil particles while vertical loading on the contained infill results in high lateral stress & resistance on the cell-soil interface. These increase the sheer strength of the confined soil, which:
- Creates a stiff mattress or slab to distribute the load over a wider area
- Reduces punching of soft soil
- Increases sheer resistance bearing capacity
- Decreases deformation
Confinement from adjacent cells provides additional resistance against the loaded cell through passive resistance, while lateral expansion of the infill is restricted by high hoop strength. Compaction is maintained by the confinement resulting in long term reinforcement.
