Concrete Floor Repair for Theatres


theatres and concrete floor repair in St. Louis and Kansas CityThe theatres in Kansas City and St. Louis are some of the largest and beautiful in the entire country. Keeping them well maintained is important. Part of the maintenance and upkeep of these theatres is concrete repair. Theatres are heavily used by the public and need to be in good repair to keep them safe and to protect equipment and furniture from being damaged.

Concrete floors can sink and crack due to the soil beneath them. When the soil constantly shifts and moves due to the changing moisture content, this creates voids beneath the concrete making the concrete sink into the voids. Repairing concrete before it fails is important. If you see sinking concrete theatre floors in Kansas City, we offer polyjacking to level concrete back to its original level.

Polyjacking Used for Theatre Concrete Floors

Polyjacking is relatively quick and efficient with the right poly equipment and products. The installation process includes drilling a 5/8″ hole through the affected concrete then injecting the polyurethane foam into the hole. The foam will expand to fill the voids beneath the concrete. As the voids are filled, the concrete is lifted back to its original level. The foam hardens within 15 minutes and then the concrete is ready for use. After the foam injection is completed, the holes are filled and the site is cleaned up. All polyurethane trucks and equipment are removed.

There are many advantages to using the polyjacking process for theatre projects. Some of these include:

  • Economical – Much less costly than removing and replacing concrete
  • Moisture resistant – Polyurethane foam guards against moisture
  • Less disruption – Polyurethane foam dries quickly so the theater can be used immediately
  • Accurate – The foam creates a precise hydraulic lift
  • Durability – Polyurethane foam is strong yet dense and can support a large amount of weight
  • Conformability – Polyurethane foam contours to the size and shape of the voids to provide total coverage

To accurately locate the voids beneath the concrete, we use ground-penetrating radar (GPR). Using a GPR is a fraction of the cost of the X-ray method and there is no exposure to radiation. The GPR units are portable and provide an instant location. This reduces the time spent on-site and gets the theatre concrete repair done more quickly.
