Keep the boards less than 8 ft 2 4 m long so they aren t too difficult to handle.
How to make a board formed concrete wall.
So our walls were indeed cast in place something essential considering it required 6 or 8 trucks and well over 200 yards of concrete.
In the picture above you can see to concrete laborers adding this layer of wood to one side of the formwork.
Stack wood planks to create a frame for the wall.
We screw the formwork together to lock everything in place.
The cheapest and easiest material to use is 2 in 4 in 5 1 cm 10 2 cm boards cut from a softwood like pine.
These wood barriers hold the concrete in place as it dries so you will need to create 2 of them.
After slab pad is compacted we dig beams and install a vapor barrier and a ton of rebar.
What made our project somewhat unique is that our walls were board formed meaning we used cedar boards instead of smooth plywood which lends a pretty distinct look and texture.
Note the rebar above slab for a house board formed wall post pour.
