Gyp-Crete was only the beginning. Maxxon®, The Floor Specialists, is recognized as the pioneer and leader in floor technologies. From the original Gyp-Crete® Floor Underlayment, Maxxon's comprehensive product line has expanded to include gypsum and self-leveling underlayments, sound control mats, and several other specialty products including a low density deep fill.
Ideal for renovation, commercial, multifamily, or single-family applications, Maxxon can solve any floor challenge. Maxxon Underlayments can be installed in wood frame, concrete construction, or over corrugated steel deck in steel frame construction.
Level-One™ EZ is a polymer-modified, self-leveling cementitious underlayment engineered for leveling, smoothing and repairing interior gypsum and concrete substrates and non-water soluble adhesive residue on concrete prior to the installation of finished floor coverings. Level-One EZ provides a durable, flat, smooth floor surface with minimum labor and installation time. It can be poured or pumped when mixed with water and seeks its own level to produce a smooth, flat hard surface.
