The Allproof Industries Perimeter Drain is an ‘off the shelf’ level threshold product that removes the process of boxing out and measuring. By simply butting the L shaped channel up against the exterior footing of the building it creates a surface to pour the concrete up against. The specially designed grate for this system is made from Glass Filled Nylon (GFN) and created in a way that it can be trimmed down on site to fit varying widths around the exterior of the building. Other grate options can be made available with custom manufacturing.

This system has been designed to be fast, efficient and cost effective due to reducing the need for custom manufacturing and providing a faster install process. This trouble free and easy to install product is the future of threshold drainage.
