Concrete has properties of expanding and contracting depending on the thermal environment. Cracking commonly occurs where two panels are connected. Therefore, mastic sealants provide a solution to this matter.

In selecting the joint filling materials, PWSS considers the following factors:

  • Thermal and shrinkage movement level
  • Fire resistance level
  • Weather exposure
  • Structural movements to be accommodated
  • Dimensional tolerance

PWSS always ensures that our mastic sealants offer several benefits to new builds. Our selected mastics can adhere properly to precast concrete, ensuring the longevity of the sealed joints. Our high-standard products and workmanship significantly improve the visual appearance of concrete joints. Our mastics are chemically resistant and durable, as part of PWSS quality assurance process. All these factors are essential standards that we follow.

Incorrect or inferior products can cause the install to sag into floor joints. To prevent this, a foam backing rod can be utilized. Rods are available in different sizes to make them suitable for any widths of the expansion joints. Priming the expansion joints is necessary to allow for maximum adhesion between the mastic and concrete substrate. This method will also increase the lifespan of the applied product.
