Sloping Floor Parking
The average person can sense if a floor slopes 1 inch in 10 feet and sloping floors or sagging floors are often one of the warning signs that structural engineers look for when analyzing a house.
Sloping floor parking. These floors are complex in terms of design and construction requiring the careful selection of a suitable drainage slope percentage drain layout construction methodology and materials. A 2 slope will probably ensure better drainage we could also find no slope tolerance for use when a floor slope is specified. Aci 117 90 standard specifications for tolerances for concrete construction and materials gives a level alignment tolerance of 3 4 inch for top of slab elevation of slabs on grade. Although most floors slope it is important to know how much and why.
If the slab elevation at the trench. The sloping exterior grade allows entry and exit directly to each floor so there are no interior ramps. As a general rule of thumb most floor to floor height requirements range from 10 to 12 feet. Minimums are limited to 8 feet 2 inches for van accessible structures and 7 feet for standard parking entrances.
Foundation issues deteriorating wood supports especially sills which rest on the foundation footer improperly installed joists or sub floors and other issues can all cause a floor to slope or sag. The perimeter walls are supported on continuous strip footings and the interior foundations are spread footings on soft sandstone. However if the second floor slopes along with the first floor then there could be a more serious structural cause such as foundation damage or settlement. If floor sloping is limited to the first story of the house that is there is no corresponding slope to the 2nd story floor then the reason could be missing support posts and damaged joists.
There are several problems that can cause a sagging or sloping floor which is one of the reasons why fixing a sloping floor is difficult.
