Advantages of Paper Form
- From constructability:
not require additional work to keep the shape
- From processibility:
dismantle readily with simple tools
- From economics:
competitive against mould made of petrochemicals or steel
- From eco-friendliness:
possible to dispose unlike the plastic material, which is a waste

How to install?
Bottom fix installation
-
- Select one from 4 installation cases shown in the pictures.
- If the column length is 4m or longer or lateral pressure of bottom concrete is expected high, ② or ③ is recommended.
The installation would be safer if it is supported with square bar.
Top area installation
-
- "It hangs beam over mould."
-
- ① Hold the square bar to column
- ② flange work (round shape)
- ③ flange work (square sitting cushion shape)
- ④ hang the beam: if beam is supported against concrete casting, it does not compromise the bearing capacity of column mould load.
Verticality alignment
-
- It is good enough to support the upper correction area.
-
- ① Place support over riased spot of square bar (for hanging stand-alone column over beam)
- ② Direct support with stiffener (bottom support reinforcement for wide column consecutive casting)
- ③ Hold stand-alone column to prevent mould from escaping due to buoyancy (turnbuckle or other accessories)
- ④ Detail view of upper side of stand-alone column (how to fix with support)
Casting
-
- Start vibrator work from hoop inside.
- Please pay attention to 4/5 of the column from the bottom as it receives most lateral pressure. The finished surface would be cleaner and smoother if bubbles are raised by vibration.
Dismantle
-
- Dismantlement
- It is easiest to dismantle 24-48 hours from casting.
With dismantling tool whose depth is adjustable, you can dismantle it without making any flaw.
Picture of beams connection
-
- If the construction requires to connect directly to column without beam, eFree form is able to make frame easily.
-
- (1) Apply tape after processing the connection area according to the drawing
- (2) Support the processed area with square bar to reinforce the lateral pressure
- (3) Process the column connection area of beam form into round shape
- (4) Connect them not to be separated from the column
- (5) Dismantle after casting in order to complete clean connected column
- Installation case of consecutive casting“How to install the form of 10 m column at once”For wide column, you can install the column form at once using eFree form connection socket.Method : Iron banding in a way to embrace the joint area with a provided socket with wooden square bar used as a support※ Socket for consecutive casting is provided for free.
Installation of wall connection
-
- For round column connected to the wall
-
- ① Locate the mould at the right position according to the drawing and process them with round saw.
- ② Finish cut area with tape after processing
- ③ Support the processed form with form or square bar to reinforce the lateral pressure
- ④ Fix the mould with external reinforcement material and nail from inside to avoid from mould escaping during casting.

- ④ Fix the mould with external reinforcement material and nail from inside to avoid from mould escaping during casting.
Installation of tiled column
-
- It is possible to install tilted column by reinforcing the mould with square bar.
What to do in the following case?
-
- If heavy rain is expected right after installation: do reinforcement work while the protective vinyl remain covered.
- If it is wet: dismantle and cover it with residual material before doing reinforcement work.
- If water remains inside the form: create discharge outlet at the bottom then reinforce the outlet.
- If multiple number of beams are connected: reinforce with square bar after processing the connection area.
Please pay extra care for the following cases
-
- During on-site processing.
- be careful when taping the processed surface.
- be mindful of bottom shock during form installation, and be careful not to leave scratches inside the reinforced bar during form insertion.
- When storing them on-site, it shall be stored in 3 or lower layers.
- Be careful not to have water welled inside.
Disposal of waste
-
- Saving them saves you money.
- The residual material from the construction site is recyclable resource that would be bought by the junk shop for fee. It is eco-friendly material that does not cost you the waste disposal fee, but rather helps to promote morale of the workers.
- Use them as a container of consumable
- It is fine to use eFree form as a container to store consumables on site. It can be used effectively as a container of consumables that are about the construction site and difficult to manage.

eFree plus
How good is it?
Reusable paper mould eFree plus
- Semicircular mould – eFree plus
- - It is light to carry around the site.
- - It can be applied to tricky processing area including beam joint.
- - This is made of paper to enable safe construction by worker.
- - It is economical as it can save the equipment rental fee of installation and transportation.
- Semicircular mould- eFree plus
- Existing method: 7-8 workers transport the mould hazardously as the site condition does not allow to use equipment such as top-down technology
- eFree plus technology: Workers who are working with eFree plus, which can be easily transported and installed for safe construction
How to install?
-
Installation tip
- Section taping
- If machining is required on site to adjust the difference in length or joint area, taping shall be done on processed section.
- Joint installation
- Utilizing the advantages ofeasy-to-process paper formwork, it is possible to construct the beamconnection, which was difficult to be done, more conveniently and safely.(Existing method, paper mould method)
- Retaining wall joint installation
- When constructing the building that is linked with the retaining wall, incision happens all the time. With paper form, you can keep the original shape without any gap or incision. Thus, it helps you construct the retaining wall quicker and more economical.
- Super wide column
- Paper mould is not only light and safe but also has excellent tensile strength. Thus it is possible to cast 9m long column as a whole at once. With unparalleled economic feasibility, it helps you enjoy safety, quality and constructional benefit on site.
"It is only possible with paper form."
- Installation of tilted column
- How can we make most of paper form? Paper form is easy to process. You can process up and bottom separately according to the tilted angle. In addition, it shows excellent strength. You can reinforce the structure with a simple tool without use of excessive material.
- Joint area
- 4M +4M = 8m, then what about joint?
If you use semi-circular socket for joint, it is more convenient to construct the upper column for consecutive casting.
- Vertical alignment
- Vertical alignment is the process that people have most of questions. There are two methods; one using general square bar and the other using angle. From construction convenience perspective, it is better to use angle. You can rent angles separately.
- Simultaneous installation of slab mould
- When installing the form of cylinder column after completing slab moulds underground parking lot of large-scale apartment complex, workers can readily insert as shown in the picture by making most of its light weight, easy process, and smooth surface.
- Exposed area
- Paper mould is largely applied to exposure concrete column which is installed with no additional finishing material as it has smooth surface without bumps.
- Others
- In case of tricky installations such as temple or rafter of Hanok (Korea traditional housing), paper form with excellent performance brings about innovation of classic housing construction.
