ELASTIC MINI - FRAMINGS WITH VARIABLE DIAMETER

The elastic Mini - Framings are especially used for the execution of :

• Galleries in concrete for the air conditioning or to drive the electric cable. 
• Beams in reinforced concrete, posts.
• Drainages in dams or other products manufactured in concrete.
• Underground pipelines for cables. 

Infalted Elastic Mini - Framing incorporated in the concrete, before its remove.	Deflated Elastic Mini - Framing to be extracted from the concrete.

The MINI ELASTIC FRAMING has been studied expressly to create in streams of  concrete the circular holes.
Its use is extremely simple, just to inflate it and to fix it in the wanted position. It makes, the concrete is flowed and as soon as soonas become hard, the MINI ELASTIC FRAMING is deflated and extracted. It detaches itself easily of the concrete. After have been deflated, the MINI ELASTIC FRAMING becomes longer and at the same time it diameter is reduced.
