VARIFLEX is a formwork system designed for shaping and casting flat slabs. With only five main components, the system is quick and easy to assemble.

Formwork installation height

From 1.46 m to 5.50 m

Load-bearing capacity of the prop

From 0.85 kN to 30 kN

Main components of the horizontal formwork

  • Telescopic prop

  • Tripod

  • U-head (fork head)

  • H20 timber beam

  • Plywood or three-layer panel

VARIFLEX is a classic slab formwork system designed for casting monolithic flat concrete slabs. Consisting of five main components, the system is quick and easy to assemble, optimizing both work time and labor costs. VARIFLEX can be adapted to any type of slab, including beam slabs — the props can be placed anywhere along the main beam.

Load-bearing capacity

Thanks to the variable load-bearing configuration, VARIFLEX can be adjusted to handle any load from freshly poured concrete, depending on the thickness of the slab.

  • The optimal and most economical use range is for slab thicknesses up to 500 mm.

  • The maximum formwork height is 6 meters.

Cost efficiency

  • A smaller number of components speeds up the assembly process.

  • Assembly and disassembly are performed manually, without the need for special equipment.

  • The system’s high reuse rate reduces long-term costs.

  • Operational flexibility helps minimize overall expenses.

  • Galvanized or powder-coated elements extend the system’s service life.

Operational flexibility

The system is easy to use and adapts well to various or changing layouts — particularly useful when dealing with irregular geometries, specific load distributions, or slabs of varying thicknesses.

Ease of use and planning

  • All components and accessories fit easily into the designated slots and lock quickly, enabling fast and efficient assembly.

  • The system fully meets the requirements for designing monolithic concrete slabs of any configuration.

Safety in operation

  • Guard rails ensure operator safety and ease of use.

  • The system provides a safe working environment during assembly and dismantling operations.

Sequence of installation of horizontal formwork

For slab thickness up to 30 cm:

  • Recommended distance between rows of longitudinal beams — 2.0 m

  • Recommended distance between props — 1.0 m

  • Recommended distance between transverse beams — 0.5 m

When concreting slabs of smaller thickness, the spacing between the formwork elements can be increased after performing preliminary static calculations, using data on the load-bearing capacity of each component in the system (plywood, beams, props).

Our specialists are always ready to help you make the correct calculation of the formwork elements and their layout scheme.
We will help you design the most cost-effective formwork arrangement for your project, depending on the sizes and types of formwork beams and plywood you are using.

Порядок установки горизонтальной опалубки

Step 1. Following the horizontal formwork layout scheme, install the props into the tripods and secure them with the locking mechanism.

Step 2. Insert the drop heads into the props. Make sure the wedge is secured in the correct position. Place the longitudinal formwork beams into the drop heads.

Step 3. Install the intermediate props, after first positioning and securing the supporting heads.

Step 4. Lay the transverse formwork beams.
Place the formwork panels (decking).

Important instructions

For the safe use of our products, all applicable safety and occupational health regulations must be observed.

The illustrations shown in this manual may depict intermediate assembly stages and are therefore not always compliant with safety standards.

Before use, inspect all materials for quality. Any parts that are damaged, deformed, or weakened due to wear, corrosion, or decay must be discarded.

Only original spare parts should be used.
Mixing our formwork systems with those of other manufacturers is dangerous and requires special technical verification.

If necessary, we can send a field installation supervisor to your construction site to provide technical assistance.

Sequence for dismantling horizontal formwork

  1. Remove all intermediate props.

  2. Using a hammer, knock out the wedge of the drop head (it should lower by 6 cm).

  3. Rotate and remove the transverse formwork beams (the beams located under the plywood joints remain in place).

  4. Remove the plywood.

  5. Dismantle the transverse and longitudinal beams.

  6. Remove the drop heads, take down the props, and remove the tripods.

Why are supporting props needed after formwork removal?

Depending on the construction process, temporary supporting props may be required to absorb the loads caused by the settling of fresh concrete or the weight of upper floor concreting.

Correct placement of supporting props

The function of these props is to distribute the loads between the freshly cast slab and the slab below it.
The loads depend on the relative stiffness of the two slabs.

Recommended ratios for auxiliary props to formwork props:

  • 0.4 auxiliary props per formwork prop, if both slabs have similar stiffness.

  • 0.8 auxiliary props per formwork prop, if the lower slab is significantly stiffer (e.g., foundation slabs).

Consult a specialist

As a general rule, regardless of the above recommendations, the issue of auxiliary supports should always be discussed with qualified structural engineers.
In uncertain cases — especially for heterogeneous slab systems — consult the engineer who performed the static calculations.

Main rule

The formwork removal process should generally begin from the center of the slab (span) and proceed toward the edges.
For large spans, this rule is mandatory.
