Green Umbrella® HydroShield™ is a hydrophobic concrete hardener and densifier reaching deep into the subsurface, creating more than a conventional shell surface. The unique formulation is resistant to surface moisture and breathable, insoluble, and fully reactive—resulting in a bond within the concrete that is stronger, denser, and less porous while repelling water. A clear, odorless solution with a natural appearance that is environmentally formulated to be a CrossOver™ densifier designed for application @EarlyAge™, @Profile&Polish™, or @MatureAge™ concrete. Unlike conventional hardeners, HydroShield is a single S.O.L.O™ application treatment that requires no scrubbing or mopping and is packaged R.T.U.™ HydroShield produces a substrate that will stain less and wear longer, reducing maintenance frequency and extending the concrete’s life cycle. Use of Green Umbrella Treatments saves considerable time and expense while eliminating hazardous waste disposal concerns, significantly cutting the environmental impact.



Green Umbrella’s architectural concrete floors provide a solid, durable surface with versatile surface-design options such as aggregate exposure, surface appearance and color. Providing a more sustainable option by elimination of off-gassing, providing highly reflective surfaces if desired and the longest product lifecycle of conventional floors.  Additional benefits are  lowering lighting, heating, and cooling costs and reducing construction waste. Architectural concrete floors are also economical with reduced construction downtime, a lower initial and maintenance cost and provide an immediate value-engineered design.  An element of DESIGN that is versatile, sustainable and economical”
