  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. 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 ...

  4. Damp proofing - Wikipedia

    en.wikipedia.org/wiki/Damp_proofing

    The DPC in the inner wall is usually below floor level, (under a suspended timber floor structure), or, with a solid concrete floor, it is usually found immediately above the floor slab so that it can be linked to the DPM under the floor slab. This enables installation of skirting boards above floor level without fear of puncturing it.

  5. Hydrophobic concrete - Wikipedia

    en.wikipedia.org/wiki/Hydrophobic_concrete

    When creating hydrophobic concrete through a coating process, a coating is sprayed or brushed onto a porous surfaces. In most cases, it is applied to a regular concrete slab that then undergoes a corrosive process to expose more of the concrete's capillaries. This can be achieved by water blasting the surface at about 3,000-4,000 psi.

    en.wikipedia.org/wiki/Arching_or_Compressive...

    The strength enhancing effects of arching action in reinforced concrete floors were first recognised near the beginning of last century. [1] However, it was not until the full scale destructive load tests by Ockleston [ 2 ] [ 3 ] on the Old Dental Hospital in Johannesburg that the extent of strength enhancement caused by arching action was ...

  7. Bituminous waterproofing - Wikipedia

    en.wikipedia.org/wiki/Bituminous_waterproofing

    Bituminous waterproofing systems are designed to protect residential and commercial buildings. Bitumen (asphalt or coal-tar pitch) is a material made up of organic liquids that are highly sticky, viscous , and waterproof. [ 1 ]
