Remove the top to create consistent strength

  • ImgAfrican Stone Restorators remove the top to create more consistent strength of the surface.

    By using proper design criteria for the concrete mix, we will likely have a concrete that is the best that nature and science has to offer. However, all concretes have inherent weaknesses that must be  overcome to maximize their performance. For example, it is a well known fact that concrete is strong in compression yet weak in flexure.

    Therefore it must be reinforces with steel to overcome this weakness. equally true, but less known, is that concrete is not uniformly hard. While this does not present a problem for structural concrete designed to carry a load, it does present a problem for concrete designed to resist  wear caused by the daily operations of a business.

    Compare Polished Concrete to Epoxy

Polished Concrete:
  • Must wait 28 days for concrete to cure before you can start grinding.
  • One can have full traffic on the floor immediately after polishing.
  • Lasts a lifetime.
  • Gives a perpetual shine and all qualities get better as time passes.
  • Implement a maintenance plan.
  • Will not peel or debond.
  • Odourless, non hazardous, no Solvents, no volatile compounds.
















Epoxy
  • Must wait 28 days for the concrete to cure before  you can apply the coating.
  • Must wait 7 days for the epoxy to cure before using the floor.
  • Another coating application is likely in 3-5 years.
  • Quality of the coating will only worsen as time passes.
  • Is a coating and can be scratched and removed.
  • 1 to10 year maximum.
  • Will wear, scratch and has the potential to debond and peel.
  • Often solvent borne with volatile compounds.
  • Often a two coat application.
Polished Concrete
  • Concrete Polishing is a finished floor solution which is both economical and ecological. Africa Concrete Restorators rehabilitates existing concrete floors and enhances new concrete floors through a  mechanical dust free diamond concrete grinding and polishing system. Concrete polishing will transform your existing concrete floor into a beautiful, functional, low maintenance, high performance floor without the use of topical coatings.

Benefits
The floor is beautiful enhancing you existing or new concrete by increasing the reflextance, or the shine of the concrete, producing a marble like luster.

The floor is strengthened: The number one cause of concrete coatings failure is hydrostatic pressure building up  under the coating. Polished concrete can breath, allowing moisture to escape while not allowing salts of efflorescence to form at the time increasing surface spill resistance.
  • Installation is cost effective: Generally installation costs for polished concrete is less than the cost of other concrete coating systems, but that's not where the savings end.
    • Reduced cost of maintenance: No need for high alkaline chemicals to clean the surface. Oil and water repellant: The system helps to prevent staining on surfaces.


      • Applications and Cost factors
      • Warehouses, Hospitals, Industrial workshops, Automotive Dealerships, Automotive Plants, Parking Areas, Driveways, Flight Hangers, Display rooms, Assembly lines, Residentuals.

        • The price is variable depending on:
        • The size of the surface, location, condition of the existing concrete, the required finish, availability of water and electricity, storage space for equipment and the special needs of the client.
