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 major structural damage as well as mold, decay, and other moisture-related problems.
Waterproof is defined by the ASTM as a treatment that resists the passage of water under pressure. [1] Generally, damp proofing keeps exterior moisture from entering a building; vapor barriers, a separate category, keep interior moisture from getting into walls.
Water intrusion into the indoor environment can be attributed from causes other than rising damp. Moisture penetration has been an ongoing problem for residences as evaporation occurs at the edge of the damp area, resulting in "tide marks" due to salt deposition. [30] The "tide mark" is commonly distinguished as a feature of rising damp.
Hard water refers to water that contains a high amount of minerals. Water picks up impurities very easily as it moves through the rock and soil. Calcium and magnesium are the main culprits when it ...
This can include moving furniture, lifting (or removing) carpets, checking behind wallpaper or paneling, checking ventilation ductwork and exposing wall cavities. Efforts typically focus on areas where there are signs of liquid moisture or water vapor , or where moisture problems are suspected. In many cases, if materials have failed to dry out ...
Glycol and boron solutions are hydrophilic (water-loving) and react with the water in wood, making it unavailable for the fungus. This is why dry rot can seem to be a little stringy; cells grown in drier periods are smaller than the larger, "plumper" cells that grow in Spring, as can be seen in tree rings used to tell how old the tree is. This ...
In construction, a building or structure is waterproofed with the use of membranes and coatings to protect contents and structural integrity. The waterproofing of the building envelope in construction specifications is listed under 07 - Thermal and Moisture Protection within MasterFormat 2004, by the Construction Specifications Institute, and includes roofing and waterproofing materials.
