Conshield – CONSHIELD® is an EPA registered anti-bacterial agent that is proven to be an effective preventative of MIC because it inhibits

WE KNOW CONCRETE

Approximately 80% of all wastewater structures in the US are made of concrete. Erosion of America’s wastewater systems by the effect of “Concrete Corrosion” is causing premature replacement of failed structures under city streets and highways causing expensive and disruptive repairs.

What is ConShield®?

ConShield® is a micro biostatic liquid concrete additive that is precisely dosed during the mixing phase to perform consistently, safely and effectively in each specific mix design produced by certified pre-casters, ready mix producers and rehab contractors. Once incorporated into the concrete mix design, imparts antimicrobial properties through out the finished concrete making the surface inhospitable to the grow of acid producing bacteria.

Used for both new and rehabilitation concrete structures:

Once incorporated into the mix design, it cannot:

Advantages of Specifying ConShield®

Durable: Prevents colonization & growth of acid-producing bacteria on concrete in sanitary sewers.
Internal Protection: Fully incorporated into the concrete mix and is molecularly bonded to its ingredients, it lasts as long as the concrete.
Cost Effective: Costs less than conventional coatings or linings. Does not require spark testing, seam welding or adhesion tests. Expensive field applications, testing and repairs are eliminated.
Proven Performance: Long-term MIC protection
Quality Control: Provided through certified agencies & each mix design is certified.
