Bulk Fill provides the perfect sub-base for all patio projects. The Bulk Fill we offer is delivered in large bulk bags. One bulk bag will cover approximately 8 square metres (coverage is calculated assuming a depth of 50mm). (Building materials are delivered usually on the same day as your patio/driveway products and are provided by a Simply Paving contracted merchant from your area. Delivery is made with a craned vehicle for this product and we are unfortunatley unable to deliver building materials on a Saturday. If you need help calculating your requirements, do not hesitate to contact our office on 0800 032 6306.
