Basement and shear walls
On long, repeating wall lines, trio formwork shortens the cycle. Corners and starter-bar details are solved on survey.

Technical specifications
Trio formwork quantities depend on wall and slab face area. The framework below is for survey before quotation; the net panel combination is locked on site.
| Item | Value |
|---|---|
| Use | Wall and slab formwork face |
| Build-up | Modular panel; clamp / wedge lock |
| Hire unit | m² / month or project m² |
| Package | Trio + vertical support (table / prop) |
| Site rule | Tie-rod spacing and striking sequence in the survey note |
| Stock | İzmir Torbalı, İstanbul Tuzla / Orhanlı, Kosova Ferizaj |
Where is it used?
Trio formwork is not a magic wand for every vertical element. It is the backbone on repeating walls and plates; if the section breaks, the system changes.
Storey walls and stair cores
The same panel family rises to the floor. In tight cores and lift shafts the panel section is fitted, not shrunk by guesswork.
Slab formwork face
The face is trio; the support below is table form or telescopic props. If either is missing, deflection and leaks appear.
Trio formwork or column-wall formwork?
Selection is not the cheapest m². Trio formwork on repeating walls; column-wall formwork on columns and special sections; table form or telescopic props under the slab.
| Case | Right system |
|---|---|
| Repeating wall / core | Trio formwork |
| Columns and special sections | Column and wall formwork |
| Slab falsework | Table form |
| Changing levels, small spans | Telescopic prop |
Frequently asked questions
What trio formwork is, when it is chosen, how price is read — short answers.
What is trio formwork?
Trio formwork is modular panel formwork used on wall and slab concrete. Panels lock with clamps or wedges; after the pour the set moves to the next element. On repeating walls and storey work it is faster than timber formwork.
When is trio formwork used?
Basement walls, storey walls, stair cores and repeating slab faces suit trio formwork. Single columns, inclined sections and highly broken geometry need column-wall formwork or special formwork.
Trio formwork or column-wall formwork?
Trio formwork on repeating straight walls and cores. Column-wall formwork on columns, special sections and low-repetition vertical elements. The support under the slab is not trio; it is table form or telescopic props. Selection follows geometry.
How is trio formwork priced?
Hire is usually m² / month; a project set is read in m². Wall or slab type, number of cycles and erection scope shift the unit price. Reference ranges are on the price page; the firm figure comes after survey.
Hire or buy?
Hire leads on a single site and limited cycles. Contractors with continuous wall work take core panel stock and hire the peak. Vertical support and the striking plan are discussed under the same roof.
