Penetrating CMW is a water-based, crystal matrix growth waterproofing material used to treat concrete slabs and provide long-term waterproofing and strength increase.

The product is a clear, low viscosity liquid that penetrates concrete and masonry building materials providing protection, strengthening and preservation.

CMW becomes an integral part of the concrete, completely waterproofing and dramatically increasing the compressive strength of the concrete structure.  The product solidifies the various component parts of the concrete into one solid mass via the development of its crystal growth thus increasing density and making the concrete permanently waterproof, tougher and harder.  The CMW will reduce hydroscopic pressure, provide better bonding for coatings and increase the hardness in the range from 25% increase to 40% overall.

It seals against radon gas; eliminates sweating floors in basements and garages; stops efflorescence and dusting; and protects against deterioration.

CMW Performance & Protection   
CMW incorporates a reactive silicate and non-silicate based multifunctional (“stand-alone”) crystal growth matrix that also reacts with hydroxides (portlandites) and tri-calcium silicate components within the pore matrix structure of the concrete.  This reaction creates a calcium-silicate hydrophilic particle grain with a non-dilutent property that will absorb penetrating liquids and substantially hinder and eliminate the passage of liquids through the concrete structure.

Hydrostatic Pressure    
The crystal growth action provides waterproofing even under hydrostatic head pressure and eliminates vapor pressure assisting as an adhesive promoter and protecting surface applied coatings such as deck coatings, urethane coatings, epoxy coatings and vinyl floor coatings from the effects of capillary moisture or vapor pressure.

Penetrating CMW

• Eliminates hairline cracks and curing cracking in new concrete

• Assists in providing a uniform cure on new concrete via chemical reaction

• Provides a complete moisture barrier

• Deeply penetrates concrete, forming an efficient pore block within the concrete structure
• Provides surface waterproofing and structural waterproofing through the whole concrete slab
• Neutralizes alkali during the reaction delivering it to the surface for removal
• Protects surface coatings from capillary rise of moisture and vapor pressure
• Seals against radon gas and eliminates sweating floors in basements and garages
• Acts as an adhesion promoter for surface applied coatings/paints
• Used in joints to stop water pressure from damaging joint materials
• CMW does not change the exterior of the concrete in appearance and the surface will take color stain (acid stain)
