Self-leveling concrete products consists of a blend of Portland and/or calcium aluminate cements, inorganic aggregates, co-polymers, and chemical modifiers, which form a flowable, self-leveling compound for leveling interior or exterior substrates. These component form a high compressive strength and flowable cementitious compound, resulting in a flat-surface that accepts ceramic tiles, natural stone, hardwood flooring, VCT, linoleum or concrete overlays. Self-leveling concrete products sold today are mixed with water only; no liquid acrylic-latex additive is required. The dry re-dispersible co-polymers in the formulations provide improved bond strength with various substrates, Self-leveling concrete products are formulated with proprietary copolymers and cements, which provide very high compressive strengths within a very short period of time after they are installed. The high compressive values results in a floor assembly that consistently passes all 14 cycles on an ASTM C627 Robinson Floor test for most applications. This 'Extra Heavy Duty; rating for the finished floor is crucial for floros that are subjected to heavy floor traffic and large equipment such as scissor lifts and pallet jacks. Alternative self-leveling applications, such as those over hydronic tubing or electric radiant heat systems. Installations over wood joist /plywood subfloor installations can provide a light commercial to a standard residential service depending upon the specific assembly detail.
The versatility of cement based self-levelers allows for self-leveling concrete pours that can be applied from 1/8" to 1.5" in a single pass. Self-leveling concrete products can also be feather-edged to transition other floor finishes. Allowable thickness vary depending upon the specific formulation. Certain proprietary formulations are available that provide an extended set for pumping. These are designed for use in high ambient temperature conditions, or over large spans when more time to float the material is required. The cure rates of self leveling concrete materials provide for a fast setting underlayment or overlayment that can accept tiles or hardwood floors in as little as 4 hours and 14-18 hours for resilient flooring or concrete micro toppings after the concrete is in place. This helps to minimize project downtime and allows the work schedule to proceed more expeditiously.
