  2. Damp proofing - Wikipedia

    en.wikipedia.org/wiki/Damp_proofing

    DPC visible between concrete foundation and brickwork. Damp proofing is defined by the American Society for Testing and Materials (ASTM) as a material that resists the passage of water with no hydrostatic pressure. [1] Waterproof is defined by the ASTM as a treatment that resists the passage of water under pressure. [1]

  3. Basement waterproofing - Wikipedia

    en.wikipedia.org/wiki/Basement_waterproofing

    The main purpose of external weeping tile is preventing water from getting into a basement. However, these pipes can become clogged or damaged, which causes excess water to put pressure on internal walls and basement floors. Water build up inside window wells, after heavy rain or snow, can lead to leaks through basement window seams.

  4. 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.

  5. Concrete degradation - Wikipedia

    en.wikipedia.org/wiki/Concrete_degradation

    The steel shuttering pinches the top surface of a concrete slab due to the weight of the next slab being constructed. Concrete slabs, block walls and pipelines are susceptible to cracking during ground settlement, seismic tremors or other sources of vibration, and also from expansion and contraction during adverse temperature changes.

  6. Flashing (weatherproofing) - Wikipedia

    en.wikipedia.org/wiki/Flashing_(weatherproofing)

    Shaped like a “U” or channel to catch water (e.g., where the edge of a tile roof meets a wall). Through wall flashing Spans the thickness of the wall and directs water to weep holes. Cap flashing (drip cap) Often used above windows and doors. Drip edge A metal used at the edges of a roof. Step flashing (soaker, base flashing)

  7. 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.
