  2. Damp (structural) - Wikipedia

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

    Structural dampness is the presence of unwanted moisture in the structure of a building, either the result of intrusion from outside or condensation from within the structure. A high proportion of damp problems in buildings are caused by ambient climate dependent factors of condensation and rain penetration. [1]

  3. Water damage - Wikipedia

    en.wikipedia.org/wiki/Water_damage

    Examples are toilet bowls with urine (no feces), sump pump failures, seepage due to hydrostatic failure and water discharge from dishwashers or washing machines. Category 3 Water - Known as "black water" and is grossly unsanitary. This water contains unsanitary agents, harmful bacteria and fungi, causing severe discomfort or sickness. Type 3 ...

  4. Damp proofing - Wikipedia

    en.wikipedia.org/wiki/Damp_proofing

    A metal damp proof course (DPC) between the stone foundation and brick wall. 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.

  5. Basement waterproofing - Wikipedia

    en.wikipedia.org/wiki/Basement_waterproofing

    Spalling is a condition where constant high humidity or moisture breaks down masonry surfaces, causing deterioration and shedding of the concrete surfaces. Other coatings can be effective where condensation is the main source of wetness. It is also effective if the problem has minor dampness. Usually, interior waterproofing will not stop major ...

  6. Seep (hydrology) - Wikipedia

    en.wikipedia.org/wiki/Seep_(hydrology)

    Seep is often used in environmental sciences to define an exfiltration zone (seepage zone) where contaminated water, e.g., from waste dumps, leaves a waste system area. Seeps are often important smaller wildlife water sources, and indicated by lower riparian vegetation.

  7. Surface runoff - Wikipedia

    en.wikipedia.org/wiki/Surface_runoff

    Surface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to channel runoff (or stream flow).It occurs when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil.

  8. Soil mechanics - Wikipedia

    en.wikipedia.org/wiki/Soil_mechanics

    Additionally DSSM explains key relationships in soil mechanics that to date have simply been taken for granted, for example, why normalized undrained peak shear strengths vary with the log of the overconsolidation ratio and why stress–strain curves normalize with the initial effective confining stress; and why in one-dimensional consolidation ...

  9. Efflorescence - Wikipedia

    en.wikipedia.org/wiki/Efflorescence

    Primary efflorescence is named such, as it typically occurs during the initial cure of a cementitious product. It often occurs on masonry construction, particularly brick, as well as some firestop mortars, when water moving through a wall or other structure, or water being driven out as a result of the heat of hydration as cement stone is being formed, brings salts to the surface that are not ...
