Old Basement Walls Built With Pouring Concrete Into Wood Forms

Cast in place cip concrete walls are made with ready mix concrete placed into removable forms erected on site.

Old basement walls built with pouring concrete into wood forms.

In heavy rains and harsh conditions wood is quicker to dry than concrete. The plywood needs to be of forming quality. With wood it is much easier to repair reinforce. 2 x 4 s and 3 4 forming plywood works best.

If they will be reused then use treated lumber. Historically this has been one of the most common forms of building basement walls. Forms are used to hold the wall in place as they dry. Thicker slabs require thicker sheathing which may be pine boards or plywood.

I have seen many homes over 100 years old with wooden basements and concrete basements. 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. Many consider aluminum and steel wall forming systems to be more productive efficient and even economical than wood forming. The same techniques used below grade can be repeated with above grade walls to form the first floor and upper levels of homes.

Concrete wall forms are typically made of plywood aluminum or steel. People prefer this option because it s sturdy and simple. Place the first piece of wood sheathing along the string line. 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.

When a foundation is poured its footing a wide flat base made from concrete and reinforced steel designed. As the name suggests poured concrete basement construction begins with the pouring of a footing for the foundation. The width and depth of the sheathing is dependent on the amount of concrete being poured. Another area where cracks are commonly found is at the bottom of the basement walls.

Plywood forms are typically used where unique wall shapes sizes and embedment characteristics are present. Finally with the weather cooperating progress has been going great. 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. 1 inch by 4 inch boards are generally stout enough for up to 4 inches of concrete.

Concrete tends to flake and break away easily which is difficult and costly to repair. 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 form will be lightweight and strong.
