This is an EPS expansion joint system for concrete floor slabs. It replaces the use of softboard used in this application as it is cost competitive and does not expand and deteriorate when wet.

DIPS expansion joint former is supplied in various thicknesses and in standard packs of 100 linear metres long..

"Dynamic, Inovative, Ecological and Professional."

Whenever casting a large horizontal expanse of concrete expansion jointing is required particularly where the concrete interfaces with perimeter walls and concrete columns.

Traditionally soft board has been used for this application. Soft board however, has a number of disadvantages as it swells when in contact with water, is difficult to cut with precision and deteriorates and becomes unsightly over time.

Expanded polystyrene however has none of these problems and thus makes an ideal expansion jointing material.


DIPS expansion joint former is manufactured using the highest quality expanded polystyrene (EPS) in various densities, thickness and widths for all expansion joint former requirements.

The DIPS Expansion Joint Former can be cut to specific sizes as requested by a professional team and contractor.

Design Features:

  • Cut to Size
  • Minimal Waste
  • Light weight

  • Easily removed for sealing purposes
  • Cost effective
  • Fire retardent
  • Flexible for circular movement joints


Forming of Expansion joints in various mediums including concrete, brickwork, paving and epoxy floors, ensuring the exact joint (width) size is achieved during construction.

Precision and quality expansion joints are easily achieved.

The DIPS Expansion Joint Former has a water absorption of 0.02%, therefore no swelling will occur as is the case when using OLD conventional soft board material.

Based on slab depth and size of slab to be cast, pre-determine quantity and size of DIPS joint former required.

Place joint former where required and if needed to be held in place before casting the slab use an EPS adhesive to glue the DIPS joint former to the supporting wall.

Some Benefits:

  • Dimensionally stable
  • Easily cut
  • Long lasting
