How Thick Should A Concrete Wall Be

So here s how thick walls should be to be soundproof.

How thick should a concrete wall be.

Depending on the. In addition to basic structural requirements wall dimensions generally member thickness are also affected by the required minimum reinforcement cover. Increasing the strength of the concrete mix or the thickness of the wall increases the wall s capacity. The thickness of the concrete and rebar depends on the environment because the pool has to be able to withstand the forces pushing against it soil outside and water inside.

A web of steel called rebar frames the concrete so that it can flex. As soon as you go higher or have greater depths of soil pushing against the wall you need to increase the thickness to 10 inches. In general poured concrete basement walls that are 8 feet tall or less and have no more than 7 feet of soil pressing against them from the outside function well at a thickness of 8 inches. How thick should a concrete retaining wall be.

Exterior wall thickness depends on siding material. This can add several inches to the wall s thickness dimensions and can vary depending on the severity of exposure soil type and reactivity etc. The thickness of interior walls is dictated by stud width and wall covering. Standard 2 by 4 studs are 3 1 2 inches wide and drywall is 1 2 inch thick so interior walls are usually 4 1 2 inches thick.

In order for a concrete room to effectively resist high winds and flying debris most rooms built with precast concrete walls rely on 12 to 16 inch thick blocks. Structural concrete work is planned to bear loads or hold weight but transfer the weight to the soil base beneath the structure. A standard stud wall built properly and consisting of 2 sheets of drywall with an air cavity 5 to 6 inches thick is good enough to make the wall soundproof. When a taller wall or a higher level of soil or both come into play the thickness should increase to 10 inches.

To be structurally sound a concrete pool shell should generally be 6 inches thick. So taller walls in heavier soils should be made thicker or with stronger concrete. Using 2 by 4 inch boards as forms and leaving a 1 2 inch clearance under the boards produces a 4 inch thick walkway slab. To keep the house and the room from being sucked into the air during a tornado large footings that work like anchors are added to the walls to hold the room in place.

The thickness of concrete is an important factor in load bearing strength but to conserve resources and avoid over building other factors are also taken into consideration. Table 4a is based directly on the aci method but for table 4b the author has applied a reduced strength reduction factor a factor of safety. A concrete wall would have to be around a foot thick to be completely soundproof. Poured concrete foundation walls that are less than 8 feet tall and have soil outside that is 6 or 7 feet deep against the wall can often be 8 inches thick and function quite well.
