2. Basement waterproofing - Wikipedia

   en.wikipedia.org/wiki/Basement_waterproofing

   Foundation crack injections are used when poured concrete foundations crack, either from settlement or the expansion and contraction of the concrete. Epoxy crack injections are typically used for structural purposes while hydrophobic or hydrophilic polyurethane injections are used to seal cracks to prevent penetration of moisture or water.

3. Spackling paste - Wikipedia

   en.wikipedia.org/wiki/Spackling_paste

   Spackling paste is comparable and contrastable with joint compound as both look similar and serve the similar purpose of filling in low spots in walls and ceilings. [3] The chief differences are that spackling paste typically dries faster, shrinks less during drying, and is meant for smaller repairs, and not for a whole room or house.

   Industrial Insulation. Rigid polyurethane foam is used in various industries to provide thermal insulation to installations and pipes. In particular, the piping for district heating systems in Europe is primarily insulated using a pre-insulated pipes sandwich assembly composed of a steel heat service pipe, an insulating layer (polyurethane foam) and a polyethylene (PE) casing, which are bonded ...

5. Crack arrestor - Wikipedia

   en.wikipedia.org/wiki/Crack_arrestor

   A crack arrestor (otherwise known as a rip-stop doubler) is a structural engineering device. Being typically shaped into ring or strip, and composed of a strong material, it serves to contain stress corrosion cracking or fatigue cracking, helping to prevent the catastrophic failure of a device.

6. Self-healing material - Wikipedia

   en.wikipedia.org/wiki/Self-healing_material

   Autogenous healing is the natural ability of cementitious materials to repair cracks. This ability is principally attributed to further hydration of unhydrated cement particles and carbonation of dissolved calcium hydroxide. [105] Cementitious materials in fresh-water systems can autogenously heal cracks up to 0.2 mm over a period of 7 weeks. [106]

7. Concrete pavement restoration - Wikipedia

   en.wikipedia.org/wiki/Concrete_Pavement_Restoration

   Dowel bar retrofit (DBR) is a process that re-establishes load transfer capability on joints and cracks by installing epoxy-coated, round steel dowels into existing concrete pavement across transverse joints and/or cracks. Slots are cut using diamond-tipped saw blades; the existing concrete is removed and the dowels are placed in the slots ...
