CombiForm System

The CombiForm system is easy to set up, and it doesn’t require the concrete to be pre-leveled before screeding. Simply connect sections of CombiForm rail to create the span you need and level them with the adjusting screws. Once the rails are set, the operator pulls the screed on top of them to achieve a flat and level floor. In addition, the plastic strip creates a joint, which controls crack formation and reduces the need for floor sawing.

Features & Benefits

  • Lightweight rail system is easy to set in place
  • Plastic guide strip allows fast, accurate screeding
  • Holes allow concrete to penetrate when vibrated for a strong product
  • CombiForm stays inside poured concrete and creates an expansion joint
  • Sections can be cut and assembled immediately prior to concreting
  • Sections are stackable for compact storage

Applications
This versatile screed rail system is suitable for all beddings. All dimensions of reinforcement bars can be used. Clips, screws and other level adjustment accessories are available separately.
