Chemical, Injectable Grouts

Mainly used as a “finger in the dike” to stop active water leaks, these Sika Grouts are available in a variety of different viscosities. Used primarily in water containment applications such as: sewer, manhole, reservoir, dams, and wastewater treatment facilities. Some products have NSF International approval.

Penetrating, Corrosion Inhibiting Coatings for Hardened Concrete

Use for steel-reinforced concrete, bridges, highways and parking garages that are exposed to corrosive environments (deicing salts, weathering). Protects against the harmful effects of corrosion by penetrating the surface of even the most dense concrete and diffusing to the steel to inhibit corrosion. Easily applied by either spray or roller to all existing reinforced concrete.

Cementitious Patching and Repair Mortars

Used for fast overhead and vertical concrete patching and spalling repairs, these materials require minimum time between lifts, have fast finishing times, are easy to use and provide high bonding strength which ensures excellent adhesion. Available in one and two component formulas, some of these special polymer-modified mortars are formulated with migrating corrosion inhibitors.

High-Strength Cementitious and Epoxy / Cement Combination Mortars – Used as a anti-corrosion coating for reinforcing steel in concrete, bonding agent for concrete repairs, repair and restore deteriorated concrete and much more, these application specific mortars are popular cost effective materials that set the standard in concrete repair and restoration.

High-Modulus, High-Strength Bonding / Gel / Grouting Adhesives

For enhancing adhesion with new concrete to old; securing bolts, dowels and pins in hardened concrete; sealing interior slabs and exterior above-grade slabs from water, chlorides, and mild chemicals; these engineered, rapid-curing, epoxy bonding grouting materials are used for all these and more suitable concrete repair and restoration applications. Several are currently listed on WSDOT and ODOT Qualified Product List.
