Premium smooth and durable self-leveling underlayment

SOLHYDFLOW SUPREME PLUS is a self-leveling underlayment that provides a flat, smooth, durable surface with minimum effort, installation time and cost. It is a single component, high strength, non-shrink, regulated setting underlayment using a polymer modified binder system to level and smooth floors. SOLHYDFLOW SUPREME can be poured or pumped (no trowel required) in one single step to thicknesses from 2 mm (1/16″) to 37 mm (1½”).

Solhydroc Inc. designs, manufactures and sells products used to repair, rehabilitate and protect concrete. The main objective is to supply materials and methods to meet and surpass the needs of the company’s clients and to propose long-term solutions that will ensure high-quality concrete.


Advanced Hydration Technology (THA) integrates calcium aluminate and Portland cement for fast setting, high strength, shrinkage compensating mortars. They rely on early hydration to minimize the residual moisture (at least 3%) that is usually found in mixtures made up of only normal Portland cement. With this technology, you can install several layers of flooring in 24 hours, allowing you move around on surfaces sooner, thus shortening the construction cycle for flooring applications. Formulations containing this technology are adapted for higher ultimate compressive strengths and provide greater durability.


Made 100% in Quebec and VOC-free, Solhydroc products contribute to LEED certifications for our customers. Plus, we use innovative manufacturing methods to reduce our ecological footprint. For more information, contact our representatives.
