Formwork for concrete wall

Formwork for concrete wall

Formwork for concrete wall

(OP)
A new concrete wall placed next to an existing wall.
How do you form a concrete wall 2" a way from an existing brick wall with out putting pressure on the existing wall.
 

RE: Formwork for concrete wall


If you intend to provide a space between the new concrete wall and the brick, there are stay-in-place systems that can be used.  Ideally that space should be about 3" or so.

Google a product called StayForm or check the link.

Use a reinforced concrete masonry wall instead.

RE: Formwork for concrete wall

Use a steel end form. Of course this depends on the thickness of the wall, but if only 200mm than a 5mm thick steel plate will be OK.The steel end form can be fixed to the wall forms and then removed later leaving the required 50mm gap.

Zambo:

I think the new concrete wall is parallel to the existing, not perpendicular.

Very simple i think
put elastic material in between (to isolate the brick wall from stress coming from the concrete 5 cm would be good)
styrodur or similar and do the wall pouring in steps. Depends on strongness and condition of the brickwall how much (level) you can pour in one step. I would like to suggest to do some small calculations before ;)


 

RE: Formwork for concrete wall

Can you use a thick OSB type of material with fixed ties. Deflection is not an issue.
