The Revolutionary Concrete Screed Rail, Stay-in-Place, Formwork System

Tec-Form is the most unique, versatile and advanced forming system available on the market today. 

This technically innovative form is capable of being used for a multiple of applications. Tec-Form has been designed and engineered for internal and external use and can be used for expansion joints, tied joints and free movement joints.

The Tec-Form profile has curved internal strengthening webs, shaped to allow the form to expand and contract, with built-in Butyl rubber compound inserts, which can re-inflate after compression and return the rail to its original position.

Until now, the issue of spalling at formed joints has been problematic, as other forms are unable to cope with thermal expansion and contraction. Tec-Form is the only system on the market that can truly expand and contract. 

Ideal for: Internal slabs, external pavements, food preparation facilities, hygenic and pharmaceutical, manufacturing facilities.


  •  Use our free engineer service to design your slab, we can issue a PS1, PS2 and PS4
  • Easy-to-use, saves time and labour costs, programme larger pours
  • Unique hinged design and compressible inserts, enable the to truly expand and contract
  • Manufactured to exact tolerances +/- 0.1mm on all diamensions
  • Fast-track installation with unique “quick-fix” fixing kit
  • Strong enough for the heaviest screeding equipment
  • Non-corrosive UV stable and chemical resistant

Tec-Form is easy-to-use and very cost-effective when compared to timber or metal forms. It will save you time and money by allowing you to programme larger pours with less labour, minimise control joints when using with our steel fibre reinforcing systems, and because the system stays-in-place there is no need for stripping formwork, moving and undertaking the installation process again and again.

Tec-Form has two sets of 25mm diameter holes at 300mm centres through the vertical blade suitable for dowels or tie bars.

Tec-Form is available in 2.7m lengths in three standard sizes. Cappings are available in either 2mm or 25mm high that can either stay-in-place or be removed for that application of a joint filler. 

Tec-Form can be installed the day before the concrete pour using concrete slabs or install the day of the pour with our unique “quick fit” fixing kit.
