Vercan Root Barrier

Shop Now

Vercan Root Barrier: A textured high density polyethylene specially designed to confine tree roots. Easy to install by using a narrow width excavator or spade and flexible enough to form any contour, Vercan Root Barrier is the simple long term solution to prevent cracked paths, roads, pipes and damage to other utilities. Made from recycled HDPE, black 1mm thickness.

Vercan Root Barrier works by deflecting roots. Roots generally will follow the path of least resistance. Most trees will not send roots below 1m depth. The length of the barrier should be between 1m and 2m outside of the drip line of the tree. A trench should be dug to the required depth. Leave the top of the barrier to just below mower height. Backfill.

Turfpave XD: A tough Grass Paver which provides architects and developers with a vehicle resistant grassed alternative to concrete, stones and asphalt pavements. Manufactured from 100% recycled polypropylene. TurfPave XD is suitable for both soils and gravel.

Turfpave Grass Pavers are a permanent lightweight and practical, aesthetically pleasing, and environmentally friendly alternative to concrete pavers. Grass Pavers are quick to install and being light they require less handling and labour.

Positioned under the grass surface, Turfpave Grass Pavers distribute loads from traffic including vehicles and pedestrian to the basecourse below. This has the effect of minimising grass and root compaction. In addition the interconnected cells allow roots to develop with minimal restriction resulting in a durable and stable grass surface which is able to withstand heavy loading.

Turfpave Grass Pavers enhance our environment by allowing the creation of stabilised and durable lush lawns which add to the quality and beauty of the environment.
