2. Basement waterproofing - Wikipedia

   en.wikipedia.org/wiki/Basement_waterproofing

   In poured concrete foundations, cracks and pipe penetrations are the most common entry points for seepage. These openings can be sealed from the interior. Epoxies , which are strong adhesives, or urethanes can be pressure injected into the openings, thus penetrating the foundation through to the exterior and cutting off the path of the seepage.

3. Epoxy - Wikipedia

   en.wikipedia.org/wiki/Epoxy

   Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called epoxy. [1] The IUPAC name for an epoxide group is an oxirane.

4. Resorcinol glue - Wikipedia

   en.wikipedia.org/wiki/Resorcinol_glue

   Until the invention of epoxy resin, resorcinol was one of the most common marine glues. Unlike epoxy, it does not have gap filling properties, requiring joints to be close fitting and clamped under pressure to achieve good results. The glue comes in two parts, a deep red syrup and a light brown powder, that are mixed to form a dark reddish ...

5. Concrete - Wikipedia

   en.wikipedia.org/wiki/Concrete

   Concrete is a composite material composed of aggregate bonded together with a fluid cement that cures to a solid over time. Concrete is the second-most-used substance in the world after water, [1] and is the most widely used building material. [2] Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminium combined. [3]

6. Composite material - Wikipedia

   en.wikipedia.org/wiki/Composite_material

   Concrete is the most common artificial composite material of all. As of 2009, about 7.5 billion cubic metres of concrete are made each year. [17] Concrete typically consists of loose stones (construction aggregate) held with a matrix of cement.

   Tail of a radio-controlled helicopter, made of CFRP. Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers (Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon ...
