Floor Slabs | WBDG - Whole Building Design Guide

IntroductionDescriptionFundamentalsApplicationsDetailsRelevant Codes and StandardsAdditional ResourcesThe base floor within a building may simply be a cast-in-place concrete slab-on-grade with limited design considerations for structural support or environmental control functions. The base floor may also be comprised of a mud or structural foundation slab complete with waterproofing and wearing slab with the overall system designed to carry structural hydrostatic pressure loads and maintain a controlled environment. Floor slabs are often the source of leakage into the building with slab cracking of common concrete materials being a primary cause. Issues of controlling soil gas emissions such as radon may also be of importance. Because the cost penalty to correct a foundation or slab on grade waterproofing failure is either extraordinarily expensive (up to 7 times the initial cost of waterproofing) or practically impossible to correct at all after construction is complete, it is better to err on the side of caution on the initial installation. Approach critical areas that will later... See full list on wbdg.org This section provides specific description of materials and systems common in floor slab systems. Descriptions and guidelines are provided in the following sections: 1. Finish Floor Coverings 2. Concrete Floor Slab 3. Aggregate Drainage Layers 4. Under Slab Vapor Retarder 5. Waterproofing Membrane 6. Protection Board 7. Prefabricated Drainage Layers See full list on wbdg.org Figure 3 contains an overall schematic that characterizes the four functions i.e. Structural Support, Environmental Control, Finish, and Distribution as they relate to the below grade enclosure element of floor slabs. The four function categories, i.e. Structural Support, Environmental Control, Finish, and Distribution, are expanded in general terms for floor slab systems. Structural Support Functions—The floor slab of the below grade building enclosure must be designed to carry downward vertical gravity loadings as well as any upward soil or hydrostatic pressure loadings. Downward vertical gravity loadings exist from the dead weight of the floor slab and any occupancy live loads. In many deeper structures the floor slab may also be a mat foundation slab carrying significant building column and wall loads. Floor slabs may also resist upward soil or hydrostatic pressure loadings. Upward soil pressures may be applied to the floor slab in situations where it is acting as a matt foundat...
