Round Column Formwork

GEOTUB is a reusable formwork in plastic for the production of round columns: unlike other formwork (in wood or cardboard), it is easy and quick to dismantle.

The GEOTUB is particularly suited to build columns when working in presence of water, which can make the work difficult and complicated. In this case, the use of GEOTUB is the only possible solution since it is made of ABS (Acrylonitrile Butadiene Styrene). In fact, this material, compared to cardboard and steel, does not suffer from degradation due to natural weathering. Moreover, thanks to its lightness and modularity, the work of the labourers are much easier even in difficult situations such as those mentioned above.

The advantages

• light, weighing max 10 kg
• quick installation and dismantling
• suitable for columns up to 6 m
• excellent smooth surfaces
• water resistant

Accessories

• Handle

Operating Instructions

Handle Assembly

• Insert handle and twist 90 degree

Ground Anchoring

• Anchoring to the ground to avoid lifting of the formwork is done using metal bracket or otherwise with timber

• Shoring

• The shoring is performed using a steel bracket to connect push-pull props to the formwork.

Pour

• Only immersion concrete vibrators are allowed. ABS formworks are not fireproof, so do not place them close to hot objects or open flame.

Handling

• Use the Geoplast lifting hook to move the assembled elements with a crane. Before lifting make sure that the lifting cables have a uniform draft.

Releasing Agent

• Always use a formwork releasing agent available as a sales product from BuildEquip.

Protective Gloves
Gauntlets, PVC, cotton or rigger gloves for hand protection.

The operations of positioning, assembling, dismantling, plumbing, handling and cleaning of GEOTUB products, as well as the pouring of the concrete, must be carried out by a competent and properly trained person or under the supervision of the site manager who must ensure that:

- All above mentioned operations are carried out properly,

- Every person working with the formworks is equipped with suitable tools and personal protective equipment to perform all necessary actions in full compliance with the safety standards,

- All panels and the supplied accessories are checked before use, discarding those which should not meet the minimum standard of reliability and safety because of the presence of any breakage and/or deformation,

- The formwork is installed on a perfectly flat surface, so as to work safely and ensure a perfect shoring and plumbing,

- All connection, alignment and plumb accessories of the formworks are properly tightened and secured to the ground before starting the pour.

BuildEquip disclaims any liability or responsibility arising from improper use of GEOTUB formwork. Any assembly of moulds and/or use of accessories otherwise described in these guidelines must first be approved by BuildEquip.

Cleaning and Maintenance Information

• Panel Cleansing

After every use, cleanse the panels with water (preferably with a pressure washer). Any deposit of concrete should be removed with a spatula or a wire brush.

• Storage

In order to facilitate the handling and lifting of the panels and all accessories, store them on pallets or battens to keep them off the ground. Although the product does not suffer weathering, it is preferable to store the panels in a dry place away from direct sunlight.
