2. Concrete sealer - Wikipedia

   en.wikipedia.org/wiki/Concrete_sealer

   They require a dry, clean surface during application to gain adhesion. Topical sealers may alter the coefficient of friction which can make substrates slick when wet – a condition that can be remedied by adding anti-skid materials. Life span is generally 1-5 years, although high-end epoxy/urethane systems can last significantly longer.

3. Basement waterproofing - Wikipedia

   en.wikipedia.org/wiki/Basement_waterproofing

   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. Concrete is both strong and inexpensive, making it an ideal product in construction. However, concrete is not waterproof.

4. Pond liner - Wikipedia

   en.wikipedia.org/wiki/Pond_liner

   Pond liners need to be protected from sharp objects (for example, stones) below the liner and from being punctured by any objects in the water body. Protection can be provided with layers of sand, geotextiles (particularly needle-punched nonwovens) and other materials. Pond liners are manufactured in rolls or accordion-folded on pallets.

5. Waterproofing - Wikipedia

   en.wikipedia.org/wiki/Waterproofing

   Masonry walls are built with a damp-proof course to prevent rising damp, and the concrete in foundations needs to be damp-proofed or waterproofed with a liquid coating, basement waterproofing membrane (even under the concrete slab floor where polyethylene sheeting is commonly used), or an additive to the concrete. Within the waterproofing ...

6. Epoxy - Wikipedia

   en.wikipedia.org/wiki/Epoxy

   This epoxy is waterproof and capable of curing underwater. The blue-coloured epoxy on the left is still undergoing curing. Epoxy adhesives are a major part of the class of adhesives called "structural adhesives" or "engineering adhesives" (that includes polyurethane, acrylic, cyanoacrylate, and other chemistries.) These high-performance ...

7. Sealant - Wikipedia

   en.wikipedia.org/wiki/Sealant

   Self-leveling silicone firestop system used around pipe through-penetration in a two-hour fire-resistance rated concrete floor assembly. Sealant is a substance used to block the passage of fluids through openings in materials, [1] a type of mechanical seal.
