High Performance FlooringMFMA MEMBER

Interflex - an Anderson Courts design - manufactured by Action Floors offers a specialty cushioned maple floor system allowing for consistent ball rebound. Interflex provides the right amount of flexibility for the demands of squash and racquetball and the nature of a start and stop game.

The field tested, high performance system effectively absorbs shock and minimizes sound transmission and vibration.

Anderson Courts is an Associate member of the Maple Flooring Manufacturers Association providing assurance that the right floor products and tolerances are met.

Ventilating Cushioned System

This high quality floating floor system features an interlock subfloor. The Interflex floor system encourages shrinkage and expansion of the floor to occur around the perimeter of the system and allows airflow below the floor.

Expanding and contracting as a unit, the Interflex floor system reduces the susceptibility to cupping and permanent damage caused by excessive changes in humidity.

The Interflex floor is designed specifically for Squash and Racquetball.

Level Floor Always

Anticipating variances in the slab, Anderson Courts uses a laser to mark concrete and set a shimming pattern to assure a level floor.
