Exterior Wall Thickness Concrete

The appropriate depth of the wall depends on several factors and there is no single standard for every home.

Exterior wall thickness concrete.

Wall weight is based on a unit weight of concrete of 150 pcf. 4 2 exterior basement wall and foundation wall. Concrete blocks used in walls should be sound and free from cracks and their edges should be straight and true. Ubc specified minimum thickness of exterior basement wall and foundation wall to be 191mm.

The tabulated values do not include any allowance for interior and exterior finishes. Spancrete wall panels can be installed vertically or horizontally for shear walls load bearing non load bearing insulated or non insulated interior or exterior walls. If load bearing masonry wall is strengthened or stiffened by reinforced concrete floors or masonry cross walls at a distance not greater than 3 65m 12 ft then it is possible to adopt thickness of 304 8mm 1 ft for maximum wall height of 21 33m 70 ft. The thickness or depth of concrete basement walls plays an integral role in their long term strength and durability.

The structural wythes are typically 6 8 or 10 thick with the insulation being 2 to 4 thickness. In addition concrete s dampening quality limits the vibration to exterior walls when doors or windows are slammed for example. Width w thickness t spacing and web thickness refer to figures r608 3 2 and r608 3 3. They can be manufactured in a variety of sizes and finishes.

The recommended maximum is 12 inches. Ubc recommends minimum thickness of bearing wall to 1 25 supported height or length whichever is shorter or not less than 102mm. It is better to construct exterior walls of 8 thick concrete block. For flat walls the weight is based on the nominal thickness.

The thickness of interior walls is dictated by stud width and wall covering. The nominal width of blocks for exterior walls and load bearing interior walls should be a minimum of 6 inches and the face shell a minimum thickness of 1. Concrete foundation walls support the home standing above so any weakness can undermine the stability of the house. N a indicates not applicable.

These enhancements can add about 0 70 per gross square foot of wall area which accounts for an increase of about 20 in the cost difference between icf and standard wood frame construction see the table below.
