Sprung Dance Floor Overview

Sprung Dance Floors Help Prevent Injuries

The most important part of any dance floor is the suspension system. It should create resilience, the absorption and return of energy through the floor. Properly done the foam blocks create an even point elasticity (compression) over the entire ballet floor, tap floor or exercise floor when landing. These foam blocks can be most likened to the cushion in your running shoes.

Four Different Suspension Methods:

  1. Closed-cell, foam blocks adhered to the bottom of the subfloor.
    1. This option provides the best resilience.
    2. Closed-cell foam blocks will retain functionality for well over 20 years.
    3. Floor height is only increased by 1.5" to 1.75"overall.
    4. Foam blocks are the choice product when building a modern sprung floor.
  2. Full Roll Padding under the sub floor.
    1. Padding provides shock absorption but not much resilience or energy return.
    2. Full roll padding, if made of closed cell foam, will last for years, but because there is no "unpadded space", dancers often have a hard time feeling the resilience of the floor.
    3. Height of floor will vary between 1.5" and 2.5", depending on foam thickness.
  3. Rubber strips under subfloor.
      Least desirable, but still provides some resilience.
  4. Basket Weave
    1. This is the original method of constructing. These were use in theatres and dance halls for years, but are not used much anymore.
    2. With the basket weave style floor, soft spots will develop where there isn't any wood support structure.
    3. Basket weave floors are 3-4″ in height.

Not a Sprung Floor:

  • Plywood stringers on top of a cement floor do NOT make a sprung floor.
  • Roll-out vinyl on top of a cement floor does NOT make a sprung floor.
