Self-Leveling Concrete

Self-Leveling Concrete is a cement that is free flowing and finds its own level. Self leveling concrete is used to create a flat and smooth surface with a similar compressive strength to traditional concrete. Self leveling has become more important as the degree of flatness required for floor covering has increased.  A flat level floor is required for best result in a finished floor.

Self-Leveling Concrete Materials & Applications

In self-leveling concrete there are two main groups of materials: underlayments and toppings. Underlayments are installed over an existing subfloor to smooth it out and correct any surface irregularities prior to the installation of all types of floor coverings, including sheet vinyl, vinyl composition tile (VCT), wood, ceramic tile and carpet. Toppings perform a similar function but act as the actual finished floor without the need for a floor covering.

Some typical applications for concrete toppings include:

  • Warehouse Floors
  • Light industrial applications
  • Retail stores
  • Institutional facilities

Concrete toppings can also receive pigmented color dyes, stains, saw cuts or mechanical polishing to produce a decorative concrete finished wear surface.

When self-leveling concrete is poured, it has a viscose but hardens enough for foot traffic in two hours and ready for finished floors in 24 hours. A gauge rake is used to move it into place without spreading it too thin. The finishing is then done by a smoother.
