• Resins | Epoxy Resins | Polyester Resins | RS Components

    Epoxy resin Epoxy resins are characterised by their excellent durability, strength, chemical resistance and low absorption of moisture. Commonly used for laminating, epoxy resin can be used as a protective coating as well as on materials in circuit boards and for patching holes in concrete pavements. These versatile resins offer high strength ...

  • Joints in Concrete Construction

    Expansion joints in concrete pavement are also seldom needed, since the contraction joints open enough (from drying shrinkage) to account for temperature expansion. The exception might be where a pavement or parking lot are next to a bridge or building—then we simply use a slightly wider isolation joint (maybe ¾ inch instead of ½ inch).

    Answer: Both can pump but rigid pavements are better suited to form the needed "parts" to generate a "pump". The primary way to make a pavement pump is for there to be a void space under the "rigid" part near a joint or crack. When traffic goes over it and forces it down it pumps water/dirt/mud o...
