Ecoply® Formrite® Formply

Formrite® is a high quality plywood produced predominantly from graded Pinus radiata. Overlaid with a hard durable resin-impregnated paper, it has a smooth finish, and its hard phenolic surface and outer veneers make it both reusable and durable. Glued with a phenol formaldehyde resin A-Type Marine bond, Formrite can withstand the rigours of construction moisture and with the addition of a cross-laminate construction it is also less likely to expand or contract when exposed to rain and temperature changes, making it an effective formply solution.

Features & Benefits

  • Multiple number of re-uses – subject to sheet care and maintenance
  • Suitable to modern optimised form systems such as table forms and jump forms
  • Applicable to a range of frame spacings, concrete slab thicknesses and surface tolerances
  • Provides builders and formworkers with an ideal surface for pouring concrete with a Class 2 concrete finish on the first pour
  • Can be used on steel or timber form frame systems
  • Lighter in weight than hardwood alternatives

CHH Woodproducts installation guidelines and AS 3610 recommendations must be followed.


Ecoply Formrite formply is manufactured under a third-party audited quality control programme and is certified by the Engineered Wood Products Association of Australasia (EWPAA) as compliant with AS 6669 for Plywood – Formwork.



Technical Notes

Framing and Plywood Thickness

For a given thickness of wet concrete, Plywood and Framing centres depend on the F grade, plywood identification code, the design limit and the direction of the face grain.

Sheet Layout

Allow a 2mm to 3mm expansion gap on all sheet edges. If required, use polystyrene filler on joint sealer in the expansion gaps.

Formwork Assembly

The objective of fixing the elements of a formwork assembly is to provide an appropriately strong rigid form that affords ease of handling, erection and stripping. The form face fixing should be designed to:

  1. Hold joints tightly together,
  2. Fix the plywood and framing so that the formwork assembly becomes a cohesive structure for handling and stripping, and
  3. Enable easy dismantling and maximum material recovery.

Additionally, the following will assist the formwork designer to achieve the required finish:

  1. When used with proper release agents, edge and face tapes and solid perimeter fixing, Formrite formply can achieve a Class 2 finish. Class 2 finish can only be assured for one pour per face as the subsequent condition of the face depends on the handling of others.
  2. If a Class 2 finish has been specified, it is a mandatory requirement of AS 3610 to provide test panels.
  3. Allow for expansion and contraction of the panels to avoid possible buckling as moisture uptake can increase the dimensions of the panel. An expansion gap of approximately 2mm is recommended.
  4. If forms are used often, use hot dip galvanised stainless steel or alloy nails or screws to avoid staining concrete.
  5. Reseal all cut edges.

Release Agents

Apply release agents sparingly. Heavy application may cause runs and colour variation in the concrete.
