formwork?

why plastic?the history: wood formwork

Wood was the material traditionally used to form concrete. It has some disadvantages:

it is slow to erect and dismantle;

not more than 20 or 30 usages;


not more than 20 or 30 usages;

skilled labour required;

suffers moisture;

job-site waste is high;

environmental issues (deforestation).

why plastic?the history: steel-frame formwork

- Speed of erection and dismantling;

- Lifetime longer than wood;

- The concrete finish superior to wood.


The biggest issues with steel?

Very heavy and expensive

High maintenance cost

High logistic cost

GeoplastGeoplast chose a special plastic for its formwork system:ABS (Acrylonitrile butadiene styrene):

- resistant and tough, very good shock absorbance

- mechanically stable under loads

Plastic formwork


- mechanically stable under loads

- very smooth and impervious surface

- temperature tolerant

- recyclable

Geoplastthe GEOPLAST formwork system

Principles common to the Geoplast formwork system:

- Very low weight

- Reusability – 100 pours at least

- Simplicity – “what ain’t there can’t break”


- Simplicity – “what ain’t there can’t break”

- Few, common accessories –one single pin/handle works for all systems

why plastic?Independent testingTensile strenght

Laboratory testing of the handles measured an

average tensile strenght (rupture) of 1,178.2 kg


why plastic?Weight: plastic formwork (Geopanel) weighs 18 kg/m2

wood = ca. 18 kg/m2 (±0%)

aluminium = ca. 30 kg/m2 (+67%)

steel frame + plywood = ca. 40 kg/m2 (+220%)

Speed: plastic formwork does not need heavy equipment, so

it is not necessary to wait for cranes, trucks or other

the ADVANTAGES of plastic


it is not necessary to wait for cranes, trucks or other

machinery.

Cost: - Long lifetime (lower amortisation per pour)

- lower operating cost (no crane time, less labour)

- lower maintenance cost (less cleaning, no or little oiling,

simple storage).

GeoplastGEOSKY® is a system of plastic formworks for the realization of concrete slabs.

Thanks to the sliding wedge on main beam, this new and innovative system makes

The GEOSKY slab system


innovative system makes installation and stripping quick, reduces casting time and increases equipment turnaround.

No special panels are needed with GEOSKY® because it uses the same panels (Geopanel) needed to pour walls.

GeoplastThe AVANTAGES of Geosky

Wood and steel slab formwork are the traditional systems.

The are time-proven, but they have some shortcomings:

- main and secondary beams are necessary

- the forming and stripping time is high:
