Forming curved surfaces can be accomplished by using plywood which can be bent to the desired radius.
Making curved concrete wall forms.
If you need to build a form for a concrete step and you want a tight radius on the front corners you could get a piece of tempered hardboard and try to bend it to the right radius but there s a better way.
If the circle is to cover a large area the sides of the form will need to be braced to prevent bulging or malformation of the planned shape.
To form a concrete wall first set up plywood boards on either side of your concrete footer and attach them together with wire.
Can we produce this curve using job built forms.
The buildradius forms create 2 4 8 12 16 and 20 arcs.
How much can we bend 3 8 inch plywood forms.
They are a lightweight polystyrene eps stay in place concrete form that speeds construction and yields a highly insulated wall.
However the plywood must be thick enough to support the load or.
Concrete forms are usually made of wood.

Each of these blocks interlocks into any buildblock 6 product line and uses the standard buildblock webs.
Acoustical applications and fire retardant properties increase the value of this construction method.
We were asked to build a curved concrete retaining wall for a homeowner.

Probably to a circle with a 3 foot radius if you bend across the grain or a circle with an 8 foot radius if you bend parallel to the grain.
But wood does not readily bend into a circular shape.
Buildradius is a family of radius forms for use in icf walls and pool construction.
The finished wall will be 7 75 in.
Then pour your concrete inside the form using a chute or hose attached to the mixer.
Some panels might undergo a localized failure at excessively short radii however.
