Robert harrington of milford ct offers his method for pouring curved concrete.
Making curved concrete wall forms.
We were asked to build a curved concrete retaining wall for a homeowner.
The curve of the wall has a radius of 4 feet.
Of concrete core and 2 125 in.
Concrete forms are usually made of wood.
They are a lightweight polystyrene eps stay in place concrete form that speeds construction and yields a highly insulated wall.
The buildradius forms create 2 4 8 12 16 and 20 arcs.
How much can we bend 3 8 inch plywood forms.
Watch the video to learn more.
Each of these blocks interlocks into any buildblock 6 product line and uses the standard buildblock webs.
Then pour your concrete inside the form using a chute or hose attached to the mixer.
But wood does not readily bend into a circular shape.
However the plywood must be thick enough to support the load or.
Build a radius wall and build your own concrete caps with.
Acoustical applications and fire retardant properties increase the value of this construction method.
To make the wall as strong as possible pour the concrete in layers no higher than 20 inches working from 1 end of the wall to the.
Forming curved surfaces can be accomplished by using plywood which can be bent to the desired radius.
The finished wall will be 7 75 in.
Some panels might undergo a localized failure at excessively short radii however.
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.
To form a concrete wall first set up plywood boards on either side of your concrete footer and attach them together with wire.
In this video we take you through the steps of how to build a wall and pour in place concrete caps.
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.
Pouring a circle of concrete requires a firm form.
Even shorter radii can be used if the panels have no knots and have a short grain or if they are wetted or steamed.
Buildradius is a family of radius forms for use in icf walls and pool construction.
