Antislip Plus® Decking boards have been specifically designed to provide a durable and effective external anti-slip surface to minimise any risk of slipping – even in adverse weather conditions.

Antislip Plus® Decking uses a unique formula of grey resin-based aggregate inserts, which are injected into the deck board grooves. If smooth boards are required, grooves are specially machined into the boards to receive the inserts.

For most uses two non-slip inserts are appropriate, but there are instances where three inserts should be used, such as on a public walkway that crosses water. Other applications also include bridleways and footpaths.
