Faresin Formwork specialises in formwork systems for the construction of circular biogas tanks without through bars.
The BioGas System offered by the company – one of the most modern and efficient biogas tank construction systems – is based on the use of full-metal, reduced-size panels.
The cement cast-facing panel surface, calendered with a very broad curve radius, is concave or convex depending on whether they are reinforcement panels of the inner side or the outer side of the circular cast.
Accordingly, with this system it is possible to build circular biogas tanks with a minimum radius of seven metres, all the while ensuring the perfect tightness of the structures, without having to use any tie rods.
Specifically, the horizontal sides of the panels for biogas tank construction are flat and perforated to fit either vertical tightening accessories or railing uprights.
The internal panels, joined to the adjacent panel by wedges, are then connected to vertical columns with fixed or adjustable struts, thereby creating a supporting structure that is able to withstand the pressure of the cement during casting. A suitable work surface is also created, where labour is stationed during casting.
Faresin Formwork has carefully developed all of the components required to build biogas tanks quickly, safely and efficiently. Ranging from external to internal formwork, as well as special panels for removal. Completing the offer are fixed and adjustable struts, vertical uprights and all of the tightening elements.
