Clarks Polysump was a gamechanger when first introduced to the Auckland market. Our range of Polysumps are still Best in Class. This 300/600 round Polysump features a series of rings at the top of the Polysump designed to lock into the concrete of a driveway. This increases the strength and durability of both the Polysump and the Driveway. For example reducing the possibility of cracking around the Polysump in the concrete driveway. This is CLARKS own design.
