2. Waterproofing - Wikipedia

   en.wikipedia.org/wiki/Waterproofing

   Masonry walls are built with a damp-proof course to prevent rising damp, and the concrete in foundations needs to be damp-proofed or waterproofed with a liquid coating, basement waterproofing membrane (even under the concrete slab floor where polyethylene sheeting is commonly used), or an additive to the concrete.

3. Gypsum concrete - Wikipedia

   en.wikipedia.org/wiki/Gypsum_concrete

   Gypsum concrete is lightweight and fire-resistant. A 1.5-inch slab of gypsum concrete weighs 13 pounds per square foot versus 18 pounds per square foot for regular concrete. [10] Even though gypsum concrete weighs less, it still has the same compressive strength as regular concrete, based on its application as underlayment or top coat flooring ...

   en.wikipedia.org/wiki/Lustron_house

   Lustron homes were usually built on concrete slab foundations with no basement. However, about 40 Lustron homes have been reported to have basements. [ 9 ] Their sturdy steel frame was constructed on-site and the house was assembled piece-by-piece from a special Lustron Corporation delivery truck.

5. Concrete sealer - Wikipedia

   en.wikipedia.org/wiki/Concrete_sealer

   In past decades attempts to protect concrete have included sealers ranging from wax to linseed oil. Today, high quality concrete sealers can block up to 99% of surface moisture. There are two main sealer categories: topical sealers (coatings) and penetrating sealers (reactive).

6. Foundation (engineering) - Wikipedia

   en.wikipedia.org/wiki/Foundation_(engineering)

   Another common type of shallow foundation is the slab-on-grade foundation where the weight of the structure is transferred to the soil through a concrete slab placed at the surface. Slab-on-grade foundations can be reinforced mat slabs, which range from 25 cm to several meters thick, depending on the size of the building, or post-tensioned ...

7. Concrete slab - Wikipedia

   en.wikipedia.org/wiki/Concrete_slab

   A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel-reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving (see below). [1] [2]
