Old Basement Walls Built With Pouring Concrete Into Wood Forms

Use treated wood if the wood will come into contact with concrete such as the wood floor plates of framed walls or wood furring strips that attach directly to basement walls.

Old basement walls built with pouring concrete into wood forms.

2 x 4 s and 3 4 forming plywood works best. Plywood forms are typically used where unique wall shapes sizes and embedment characteristics are present. Many consider aluminum and steel wall forming systems to be more productive efficient and even economical than wood forming. Place the first piece of wood sheathing along the string line.

1 inch by 4 inch boards are generally stout enough for up to 4 inches of concrete. For tom good means steel reinforced foundation walls and footings made of poured concrete. The plywood needs to be of forming quality. By comparison all the laboriously assembled foundations of stone brick and mortar that have supported buildings for centuries even the walls of concrete block that most builders were using when this old house was launched 25 years ago are.

Finally with the weather cooperating progress has been going great. In heavy rains and harsh conditions wood is quicker to dry than concrete. I have seen many homes over 100 years old with wooden basements and concrete basements. People prefer this option because it s sturdy and simple.

As the name suggests poured concrete basement construction begins with the pouring of a footing for the foundation. The same techniques used below grade can be repeated with above grade walls to form the first floor and upper levels of homes. Poured concrete basements are probably the most common type construction. If they will be reused then use treated lumber.

Another area where cracks are commonly found is at the bottom of the basement walls. Cast in place cip concrete walls are made with ready mix concrete placed into removable forms erected on site. If you pour a basement foundation the foundation walls will need to sit and cure a little bit before the next step can occur. The width and depth of the sheathing is dependent on the amount of concrete being poured.

Historically this has been one of the most common forms of building basement walls. Thicker slabs require thicker sheathing which may be pine boards or plywood. With wood it is much easier to repair reinforce. Typically homebuilders will have a concrete foundation cure for about 7 10 days in our region so we must practice some patience.

The 2 x 4 s should be no 2 kiln dried pine simply because it is cheap easy to work with and holds nails very well. Forms are used to hold the wall in place as they dry. Concrete wall forms are typically made of plywood aluminum or steel.
