Old Basement Walls Built With Pouring Concrete Into Wood Forms

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.

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. 1 inch by 4 inch boards are generally stout enough for up to 4 inches of concrete. In heavy rains and harsh conditions wood is quicker to dry than concrete. 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. With wood it is much easier to repair reinforce. 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.

I have seen many homes over 100 years old with wooden basements and concrete basements. 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. Thicker slabs require thicker sheathing which may be pine boards or plywood. 2 x 4 s and 3 4 forming plywood works best.

Finally with the weather cooperating progress has been going great. Place the first piece of wood sheathing along the string line. Many consider aluminum and steel wall forming systems to be more productive efficient and even economical than wood forming. If they will be reused then use treated lumber.

People prefer this option because it s sturdy and simple. For tom good means steel reinforced foundation walls and footings made of poured concrete. Concrete wall forms are typically made of plywood aluminum or steel. Plywood forms are typically used where unique wall shapes sizes and embedment characteristics are present.

The form will be lightweight and strong. As the name suggests poured concrete basement construction begins with the pouring of a footing for the foundation. Historically this has been one of the most common forms of building basement walls. Typically homebuilders will have a concrete foundation cure for about 7 10 days in our region so we must practice some patience.

The same techniques used below grade can be repeated with above grade walls to form the first floor and upper levels of homes. Concrete tends to flake and break away easily which is difficult and costly to repair. Forms are used to hold the wall in place as they dry.
