Australian-engineered permanent formwork

ReoLok.

Fast-track non-combustible commercial walls. ReoLok uses the reinforcing bar itself to lock opposing fibre-cement panels into place creating a super strong cassette before concrete placement.

REOLOK® / PANEL LOCKING

How it works

The cavity stays open
until you’ve checked it.

Lightweight 6mm fibre-cement panels, steel reinforcement and the ReoLok connection system create a rigid cavity that remains open for reinforcement inspection before the opposing panels are installed and concrete is placed.

✓Panels up to 3600mm high × 1200mm wide — reinforcing steel locks adjacent panels together
✓Full cavity visibility — engineers visually verify reinforcement before the cavity closes
✓Lighter panels — improved safety and faster installation
✓Non-combustible connectors and fibre-cement faces — NCC-ready for external walls
✓Lower production and logistics costs — commercial medium-rise structural walls

Best applications

Where ReoLok earns its keep.

Inter-tenancy & corridor walls

Fire-rated, acoustically rated party walls for multi-res and commercial.

Lift & stair shafts

Rigid, inspectable cores without conventional blockwork.

Retaining & basement walls

Below-ground structure with verified reinforcement before the pour.

Blade walls

Slender structural walls for medium- to high-density construction.

External load-bearing walls

Non-combustible faces, rebated and ready for textured render or cladding.

Internal dry-lined walls

Dry-line internally for plasterboard finishes.

Frequently asked questions

What can I build with ReoLok?

Residential and commercial buildings, factories, warehouses, shopping centres, basement and retaining walls, apartments and inter-tenancy walls — external and internal load-bearing walls across the board.

What are the standard ReoLok models?

RL162 has a 162mm finished wall with a 150mm concrete core (180/180/180). RL200 has a 200mm finished wall with a 188mm concrete core (240/240/240). Both are documented in the November 2025 ReoLok Design Manual.

Can the reinforcement be inspected before concrete placement?

Yes — the wall cavity remains open so engineers can visually verify reinforcement placement before the opposing panels close the cavity.

Does Formcraft provide technical assistance?

Yes — technical support is available for architects, engineers and construction teams. Project-specific design and certification remain the responsibility of suitably qualified consultants.

Can I manufacture or distribute ReoLok?

Interstate and overseas builders, manufacturers and partners can produce ReoLok under licence — see the licensing pathway for the process.
