Sauereisen, a Pittsburgh, PA, company specializing in coating and lining systems, is preparing an unprecedented round of product introductions to occur at WEFTEC 2011. The new offerings include substrate repair materials used to restore corroded concrete and specialized protective barriers designed to resist aggressive chemicals. The new products include:

SewerGard 210X – Case histories of the original Sauereisen 210 corrosion-clad polymer lining span 20+ years. One of the first significant applications occurred in the Jefferson Parish Lift Station in New Orleans, LA. The epoxy polymer lining lasted as long as the structure itself, eventually completing its service life upon the aftermath of Hurricane Katrina.

A new version of SewerGard, Sauereisen’s 210X, exhibits compressive strength exceeding 15,000 psi. This attribute appeals to specifying engineers seeking to draw direct comparisons among a myriad of protective linings. Manholes subjected to heavy stress represent a typical area where the product would be used. It is also intended for preserving the concrete and steel infrastructure of wastewater treatment plants. In either area, the environmentally friendly nature of the product (100% solids, zero VOCs) offers additional benefit.

SewerGard 210G – The company’s improved 210G is the next generation “Glaze” version of SewerGard. It may be applied via plural-component spray equipment to facilitate rapid installation. Applicators appreciate the ability to forgo batch mixing of the two-component product so that jobsite labor is reduced.

Another enhancement is the ability to build greater thickness. The prior version was specified strictly at 20 mils thick, typically for applications seeking a glossy topcoat over troweled or fiber-reinforced linings. The new 210G is able to be sprayed at double the thickness for added durability when used as a stand-alone lining.

By combining the formula’s greater thickness with the added convenience of plural component spraying, it is an attractive option for clarifiers, tanks, and structural steel at wastewater treatment plants.

SewerSeal F170 is a modification of Sauereisen’s calcium aluminate lining that can be spincast in wet wells and manhole.

RestoKrete 208 – Consistent with Sauereisen’s expertise in combining organic and inorganic chemistries, this hybrid underlayment blends the bond strength of epoxy with the economy of cement. RestoKrete is a substrate repair material used in the process of restoring structural integrity to underground concrete. It would be installed prior to the application of a corrosion resistant topping such as SewerGard.

The high bond strength (withstanding over 1,000 psi slant-shear per ASTM C-882) and 800+ tensile strength of the product represent a significant upgrade from strictly cementitious underlayments. The epoxy element of the formulation makes it a strong option for the repair of brick or concrete surfaces found in tunnels or manholes. Since it offers benefit in restricting water infiltration as well, RestoKrete aids in the prevention of blisters that might otherwise occur in a protective topcoat.

SewerSeal F170 – Where a cement-based material is desired to serve as a stand-alone lining, many municipalities opt for calcium aluminates. SewerSeal F170 is a modification of Sauereisen’s calcium aluminate lining that prevents negative-side water pressure from infiltrating underground infrastructure. The new formulation affords lower permeability and improved handling characteristics. Contractors appreciate the material’s ability to be pumped and spincast at greater thickness upon the walls of wet wells and manholes. SewerSeal withstands chemical-resistant service in areas subject to mild acids and alkalis.

Sauereisen is introducing new repair materials used to restore corroded concrete and specialized protective barriers designed to resist aggressive chemicals.

ConoFlex 381 – Through a proprietary technology partnership, Sauereisen has introduced a new polyurethane lining that offers a combination of elasticity and chemical resistance. ConoFlex 381 exhibits 40% elongation and very low water vapor transmission (0.012 grams per 100 square inch at 35-40 mils thick). Due to the lining’s flexibility and impermeability, it is recommended for use at treatment plants in containment areas and structural locations subject to corrosion. A variation of the product, No. 381.61, is NSF-approved for exposure to potable water. ConoFlex also carries a BioPreferred designation by the USDA based on the formulation’s high content of renewable materials.

Pre-Krete Tankliner 61 – The NSF-61 designation now applies to this cementitious liner used for corrosion resistance in hot water tanks. Any tank subject to the potentially corrosive effects of hard or soft water is a candidate for application. Pre-Krete T61 is available through Pocono Fabricators, a wholly owned subsidiary of Sauereisen.

Conclusion

All together, these new materials by Sauereisen represent the expansion of its water/wastewater product line by roughly 40%. The company distributed a comprehensive internal launch package in July 2011 for the purpose of educating its representatives. In addition, continuing education of qualified applicators is on-going by the company’s tech service team.
