For decades, Regupol® Growth-Inhibiting Mats have been an established product for avoiding unwanted vegetation. Their use bypasses the unpopular use of herbicides, permanently prevents unwanted growth and makes frequent mowing unnecessary. The mats prevent the penetration ot UV light so that the plants under the mats cannot grow. The mats are permeable to water, thus preserving microbial soil life and avoiding erosion. The weight of the mats means that they lie safely and firmly in position, and their material composition means that they do not rot.
