Composite Rig Mats
HDPE composite rig mats are a better choice than fiberglass. HDPE has enough flexure to conform to uneven terrain, while fiberglass mats are rigid and brittle. It could be potentially dangerous if a mat were to break in two while being traversed by a heavy crane or other equipment. Not only are fiberglass mats more likely to break, they are also much harder to fix when they do, whereas small repairs can be made to composite mats in the field.
