Ease of Installation
Basic installation is extremely simple. The panels are pre-cut for installation on 12″, 16″ and 24″ on-center framing. The unique cut of the panels allows the drainage trough to form automatically during installation.
The DEK Drain materials are easily handled by one person. The only tools needed are a stapler (hammer-tacker, electric or pneumatic), sharp scissors and a razor knife. No measuring, gauging, sizing or caulking is necessary.
