Stay-in-place formwork for expansion joints Stremaform®

Decoupling of concrete components

Stremaform® formwork elements for expansion joints decouple components and absorb their movements within the joint.
The elements are used as permanent formwork in floor slabs, ceilings and walls. The formwork elements are prefabricated by us to size, no stripping is required. Reinforcement and concreting can be continued independently and without interruption.
We produce the expansion joint elements with the joint insert of your choice: Rigid foam, heat-resistant mineral wool or
sound-insulating mineral fibre.

Advantages

    • Faster and more cost-effective formwork compared to timber formwork
    • Reliable and functional formwork element
    • No dismantling or disposal of formwork material
    • Proven quality: Engineered in Germany for over 30 years

Stay-in-place formwork for expansion joints Stremaform®

Stay-in-place formwork for expansion joints Stremaform®

without sealing

Stremaform® stay-in-place formwork for expansion joints is the most efficient solution for creating movement joints in concrete structures.

We produce elements on a project basis and deliver them ready for installation to your building site.

Stay-in-place formwork for expansion joints Stremaform® with rubber water bar cage

Stay-in-place formwork for expansion joints Stremaform® with rubber water bar cage

for sealing of impermeable joints

If the expansion joint is to be additionally sealed, a rubber water bar cage is integrated into the Stremaform® stay-in-place formwork for expansion joints during production. The expansion rubber water bar is inserted into the cage at the building site. The built-in expansion joint fixer ensures the correct position of the rubber water bar.

For wide rubber water bars, we recommend a formwork element design in which the rubber water bar is rolled out on the lower part before the upper part is positioned and secured.

Stay-in-place formwork for expansion joints Stremaform® with sound insulation

for the acoustic separation of concrete components

The Stremaform® elements for sound insulation are used for acoustic decoupling of concrete components. In semi-detached and terraced houses, this avoids the transmission of sound between neighbouring homes.

A rubber water bar cage can be integrated into the element to seal the sound insulation joint. The expansion joint tape is inserted into the cage on building site.

NewsCONCRETE Magazine: Simplified Joints with Stremaform®
Expansion joints in concrete structures are particularly complex and cumbersome, from the design and planning stage all way to execution in the field. Whenever the transmission of transverse/shear forces in combination with structural waterproofing is required, the task becomes even more daunting.
