Simple Installation & Expert Service
It's easy to hang your DELTA below-grade waterproofing system when you have the right DELTA fastener. Simply nail the DELTA-FAST'ner to the membrane or board using a DELTA-NAIL or concrete nail. The fastener is made of high-density polyethylene (HDPE) plastic that's colored orange so it stands out on a drainage roll or board. With 500 pieces per box, you can hang as many DELTA drain boards as you need to manage water flow. Order a box now at an affordable price from Spycor Building Products.
