Rocker and Kicker in Mivan Shuttering: Meaning, Uses & Differences – Construction Phase
Quick Answer
The rocker in Mivan shuttering controls the lateral alignment of wall panels during casting, while the kicker in Mivan shuttering positions the base panel accurately before each lift begins. Both are essential alignment components for the Mivan aluminium formwork system. The proper application of both reduces rework, preserves plumb accuracy, and assures that each subsequent floor is cast to the exact dimension and position.

Introduction
The rocker and kicker in Mivan shuttering are two of the most commonly misunderstood components of aluminium formwork. Engineers on site commonly enquire about what distinguishes them, when to utilise each, and what happens to the building if either is installed incorrectly. Getting these components properly is critical because they directly affect the precision and plumb of every wall panel cast in the system.
This guide fully explains both components, including their definitions, purposes, and applications, as well as the unique differences that govern how each is employed at different stages of the Mivan construction technology process.
Key Components of the Mivan Shuttering System
What Is the Mivan Shuttering System?
The mivan formwork system is a fast building method that uses custom-fabricated aluminium panels to form walls, slabs, beams, and columns in a single, simultaneous pour. The technique, developed by Mivan Company Ltd in Malaysia, is now widely used throughout India for large-scale residential and commercial construction where recurring floor designs necessitate speed, accuracy, and structural uniformity. Aluminium formwork panels are connected using pins and wedges, supported by props, and held in precise alignment by a series of specially developed accessories.
What Is a Rocker in Mivan Shuttering?
A rocker in Mivan shuttering is a wedge-shaped or pivot-action aluminium accessory attached to the base slab or the already-cast floor to control the lateral position of wall form panels. Once pinned in place, it keeps the bottom of the wall panel from sliding inward or outward relative to the structural grid line during concrete pouring and vibration.
What Is a Kicker in Mivan Shuttering?
The kicker in Mivan shuttering is a cast aluminium tube or plate fastened to the top surface of the previously poured slab, precisely at the wall line, before the next set of wall panels is installed. It establishes a physical datum that places the base of each new wall panel squarely above the planned wall centerline for the upcoming floor lift.
Rocker vs Kicker in Mivan Shuttering: Key Differences
The difference is best appreciated by comparing their timing, positioning, and the specific difficulty that each solves in the construction phase. They are complementary and not interchangeable:
Features | Rocker in Mivan Shuttering | Kicker in Mivan Shuttering |
| Purpose | Controls lateral movement during pour | Sets the base position before panel erection |
| When installed | After the kicker, during panel assembly | First, before any panel is placed |
| Placement | Against the base of the wall panel, on the slab | On the slab surface at the wall grid line |
| Function type | Active resistance during pour | Passive datum at panel erection |
| Adjusted by | Formwork gang during assembly | Survey team from structural drawings |
| If installed wrong | Panel bulges or offsets under the pour load | The entire wall run is mispositioned in the plan |
| Reuse | Stripped and reused every floor cycle | Removed after panel erection; reused |
How Do Kicker and Rocker Work Together in Mivan Shuttering?
Understanding kicker and rocker in Mivan shuttering as a system, rather than individual components, enables site crews to install Mivan correctly every time. Their interaction is sequential and interdependent: the kicker determines where the wall begins, and the rocker ensures that it remains there during the pour.
Step 1: Kicker sets the position
The survey team marks wall grid lines on the slab. The kicker is fastened to the slab at the exact wall line shown in the structural plans. All panels in the run will correspond to the kicker’s position.
Tolerance: ±2 mm maximum from grid line
Checked by: Site engineer before panel erection begins.
Step 2: Rocker holds under the pour load
Panels are built along the kicker channel. The rockers are then fixed to the slab’s panel base. During concrete pour and vibration, the rocker distributes lateral pressure from the panel base into the slab, rather than allowing displacement.
Checked after pour: Before stripping, verify that there is no movement.
Components of the Mivan Formwork System
The Mivan system’s aluminium formwork components work together to form an integrated unit. Understanding how rocker and kicker integrate into the larger component set allows site crews to precisely plan erection processes and guarantee that all elements are in place before pouring begins.

- Slab panel
- Corner panel
- Kicker
- Rocker
- Pin and wedge
- Soldier (waler)
- Slab prop
- Tie rod and cone
Rocker and Kicker Installation Process and Common Mistakes
Formwork Installation Process: Where Rocker and Kicker Fit
Mivan Construction’s formwork installation procedure follows a rigorous order. Understanding where the rocker and kicker fit within that sequence avoids the usual error of putting them out of order, which causes rework and delays the pour cycle:
| Stage | Activity | Rocker/Kicker Role |
| 1 | Survey team marks wall grid lines on the slab | The kicker position is set from the grid marks |
| 2 | Kickers are fixed to the slab at all wall lines | Kicker installed here — first component |
| 3 | Wall panels are erected into kicker channels | Panel drops into kicker datum |
| 4 | Pins and wedges connect panels | — |
| 5 | Rockers are pinned to the slab against the panel base | Rocker installed here — lateral restraint |
| 6 | Tie rods and soldiers are fitted and tightened | — |
| 7 | Slab panels and props are placed and levelled | — |
| 8 | Concrete is poured, vibrated, and cured | Rocker holds panel during pour |
| 9 | Stripping: rocker and kicker removed first | Both are stripped for the next cycle |
Common Errors in Rocker and Kicker Installation
Field errors in the kicker in Mivan shuttering and in how it is installed account for a large portion of wall alignment flaws in Mivan construction. The following are the most often observed mistakes on site:
- Kicker set from the wrong datum
- Rocker installed before the kicker is checked
- Rocker not pinned to slab
- Wrong rocker size for panel height
- Skipping rockers on internal wall junctions
Site Tips for Correct Rocker and Kicker Use
These site-level guidelines help civil engineers and supervisors achieve consistently accurate outcomes for both components across every floor cycle:
- Verify kicker position before panel erection
- Colour-code rocker and kicker sets
- Record kicker deviations
- Check the rocker pins after the first concrete truck
- Store rockers and kickers by size

Conclusion
The rocker and kicker in Mivan shuttering are two of the most critical precision components in the complete aluminium formwork system. The kicker determines where each wall begins. The rocker guarantees it will remain there. When used correctly, in the precise sequence, and with the appropriate size for each panel, they provide millimetre-level accuracy, making Mivan construction faster, more consistent, and substantially less prone to post-pour faults than traditional shuttering methods.
