Underground Drainage Ranges

Underground drainage systems are used to move waste and rain water away from the house and its surrounding area. They are made up of pipe, fittings and risers which are joined together to create a continuous linked system. Underground Systems are suitable for new build or refurbishment projects as PVC-U gives a strong, durable product that is lightweight and easy to handle.
