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 ...
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 ...
Concrete sealers are applied to concrete to protect it from surface damage, corrosion, and staining. They either block the pores in the concrete to reduce absorption of water and salts or form an impermeable layer which prevents such materials from passing.
Damp proofing in construction is a type of moisture control applied to building walls and floors to prevent moisture from passing into the interior spaces. Dampness problems are among the most frequent problems encountered in residences. DPC visible between concrete foundation and brickwork.
Other reasons for covering concrete with synthetic resin flooring are to improve resistance to chemicals, enhancing resistance to impact and wear, and for aesthetic appearance purposes. Seamless polymer flooring can take many forms: [8] Floor seals applied at less than 6 mil (0.15 mm) Floor coatings applied at 6 - 12 mil (0.15 – 0.3 mm)
In areas below foundation level (subgrade areas), particularly those formed in concrete, vapor retarder placement can be problematic, as moisture infiltration from capillary action can exceed water vapor movement outward through framed and insulated walls. A slab-on-grade or basement floor should be poured over a cross-laminated polyethylene ...
