  2. Basement waterproofing - Wikipedia

    en.wikipedia.org/wiki/Basement_waterproofing

    Waterproofing and drainage considerations are especially important in cases where ground water is likely to build up in the soil or where there is a high water table. Water in the soil causes hydrostatic pressure to be exerted underneath basement floors and walls. This hydrostatic pressure can force water in through cracks, which can cause ...

  3. Damp proofing - Wikipedia

    en.wikipedia.org/wiki/Damp_proofing

    A DPC layer is usually laid below all masonry walls, regardless if the wall is a load bearing wall or a partition wall. A damp-proof membrane (DPM) is a membrane material applied to prevent moisture transmission. A common example is polyethylene sheeting laid under a concrete slab to prevent the concrete from gaining moisture through capillary ...

  4. 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. Within the waterproofing ...

  5. Vapor barrier - Wikipedia

    en.wikipedia.org/wiki/Vapor_barrier

    A slab-on-grade or basement floor should be poured over a cross-laminated polyethylene vapor barrier over 4 inches (10 cm) of granular fill to prevent wicking of moisture from the ground and radon gas incursion. Inside a steel building, water vapor will condense whenever it comes into contact with a surface that is below the dew point temperature.

  6. Damp (structural) - Wikipedia

    en.wikipedia.org/wiki/Damp_(structural)

    The way to prevent this is to insert above the ground level but below the floor level, either a course of vitrified stoneware made on purpose, or two layers of slates laid in cement, or some equally effective impervious material, the intervention of which between two courses of brickwork bars will prevent the further upward progress of the damp ...

  7. Basement - Wikipedia

    en.wikipedia.org/wiki/Basement

    The finished floor is typically raised off the concrete basement floor. In countries such as Canada, laminate flooring is an exception: It is typically separated from the concrete by only a thin foam underlay. Radiant heating systems may be embedded within the concrete floor. Even if unfinished and unoccupied, basements are heated in order to ...

  8. Concrete leveling - Wikipedia

    en.wikipedia.org/wiki/Concrete_leveling

    In civil engineering, concrete leveling is a procedure that attempts to correct an uneven concrete surface by altering the foundation that the surface sits upon. It is a cheaper alternative to having replacement concrete poured and is commonly performed at small businesses and private homes as well as at factories, warehouses, airports and on roads, highways and other infrastructure.

  9. Trench drain - Wikipedia

    en.wikipedia.org/wiki/Trench_drain

    Attaching the drainage pipes to the suspended form; Filling the trench with concrete (surrounding the form base and sides) and finishing the concrete flush with the metal frame; And after drying, removing the wooden form, cleaning the pipe inverts and placing the grates in the frame. This installation method is by far the most labor-intensive.
