Southern Bleacher created the original interlock decking system - an innovation we developed for Boston College in 1991, when our Research and Development team delivered a solution for fully controlling water and liquids to prevent them from draining below or out the front of the stadium.
While Southern Bleacher has always taken a conservative approach to materials and design - being careful to adopt only what will stand the test of time - the Interlock innovation, the team came back with was a clear winner from day one, and was implemented immediately.
Since then, others have copied our interlock design, but the original-continually updated - is still the best.
In a normal tongue and groove system, the male edge of one plank fits into the female edge of the adjacent plank, creating a rigid connection.
At the same time, a gutter channel positioned below the male and female joint runs the full length of each plank, catching any liquid draining through the planks and then directing that moisture as desired from underneath the stadium.
The channel also serves as a brace between planks, locking down any back-front movement.
