Earth Shield Supplies Chemical Resistant Waterstop to New GE Sodium Nickel Battery Plant That President Obama Promoted During Recent Visit

President Barack Obama visited the Capital Region Friday, January 7th, 2011 where he touted America's business potential during a trip to General Electric located in Schenectady, NY where he toured a new battery plant with General Electric CEO Jeffrey Immelt.
The president introduced Immelt as the head of a Council on Jobs and Competitiveness. Obama said the panel will focus on getting people back to work and making our nation more competitive on a global level.

During his speech, President Obama said that as the economy slowly recovers, the challenge is to make it easier for people to expand new businesses and for existing companies to hire new workers. The president also said that in order for the economy to fully recover, U.S. companies must expand their exports to overseas markets.
GE is making a move into the sodium-based battery business with a $100 million battery manufacturing plant in upstate New York. The company has previously invested heavily in lithium ion batteries — the batteries of choice for hybrid and electric cars — but the new sodium-nickel-chloride batteries will power GE's hybrid locomotives. The batteries could also be used in data centers, trucking equipment for mining, and alternative energy storage.
GE has held patents on the sodium-based batteries, which store energy produced when vehicles brake, for over five years. The company believes sodium-based batteries are superior to lithium batteries for locomotive purposes because the former provides large amounts of power spread over a long period. In comparison, lithium ion batteries provide short bursts of power that can jolt a vehicle into moving.
Earth Shield® brand chemical resistant waterstop is currently being installed throughout the new battery plant in all the containment areas and trenches. An on-site waterstop welding training class was held on March 9th, 2011, certifying the contractor — Lechase Construction Services of Schenectady, NY. The entire crew was trained over the course of one day and construction commenced immediately. Both retrofit and base seal waterstops were used throughout.
The battery factory, scheduled to open in mid-2011, will provide a much-needed economic boost to Niskayuna, New York, with 350 factory jobs and $100 million in investment — some of which GE hopes will be provided for with government economic stimulus funding. At full capacity, GE's sodium-based battery factory will produce 10 million battery cells (900 MW hours of energy storage) each year.
Earth Shield is proud to be a small part of this factory of the future.

Waterstop for Corner Joints

Earth Shield® Waterstop profile JP540L is the perfect solution for sealing corner joints between wall/wall or wall/slab on environmentally engineered concrete containment structures.  The product is externally applied using factory supplied novolac epoxy, stainless steel Tapcons®, and stainless steel batten bar.

Earth Shield Retrofit Waterstop for a Variety of Applications

Joining new concrete to existing concrete requires the use of a waterstop if the joint is to be fluid-proof. However, this formed joint has always been problematic for Engineers and Contractors, as properly installing a standard waterstop across a preformed joint is difficult, expensive, and usually a compromise. Traditionally, Engineers have accomplished the task by specifying the use of a standard embedded waterstop within a sawcut and epoxy-grout filled channel. This labor-intensive and costly method has often produced questionable results due to the potential cold joint formed between the epoxy and the existing concrete surface from shrinkage. Furthermore, by sawcutting the existing concrete, the Contractor may be inadvertently destroying the reinforcing steel within the concrete.

Earth Shield currently manufactures six polymer systems that offer Engineers, Owners, and Contractors real solutions for retrofitting applications. All of the systems are non-destructive — there is no sawcutting of the existing concrete, and therefore no destruction of the internal reinforcing steel. All of the systems feature chemical bond (epoxy), as well as mechanical anchor system (stainless steel batten bar and bolts). All of the systems are manufactured from a fully cross-linked thermoplastic vulcanizate (TPV), which provides broad-spectrum resistance to a variety of aggressive chemicals, long life span (entire lifecycle of structure), and excellent physical properties (tensile strength, elongation, etc.).

All six Earth Shield retrofit waterstops systems can be installed either vertically or horizontally. Therefore, they are equally suited for joining slab to wall or wall to slab. A frequent application is for the Contractor to pour the slab monolithically; apply an Earth Shield retrofit waterstop system to the cured slab (green concrete is perfectly acceptable); and cast containment walls (curbs) on top of the waterstop. All of our retrofit waterstop systems can be factory fabricated to fit-to-print dimensions, leaving little to no welding for the Contractor in the field.

New Retrofit Waterstop Profile Accommodates Very Large Joint Movements

JP Specialties, Inc. has developed a new Earth Shield® waterstop product specifically designed to accommodate large shear movements, such as tank ring foundations subjected to settlement. The JP621L Retrofit Waterstop System is chemically and mechanically adhered to the existing concrete using one of our chemical resistant, novolac epoxies (VEN500 or VEN1000), stainless steel batten bar, and stainless steel anchor bolts. The waterstop profile is combed along the fastening leg, which facilitates the epoxy bonding to the profile. The embedded waterstop leg has two large polymer dams which are designed to create a torturous fluid path and simultaneously perform as anchor points for the new concrete to bond to. The JP621L profile has a large, tear-web centerbulb that can move greater than five inches without deformation of the waterstops main body. (The thin diaphragm, or "tear-web", ruptures under shear stress, allowing the "U-bulb" to move freely for its entire length when installed in an open joint.) JP621L Retrofit Waterstop can be heat welded to a continuous, fluid-tight barrier, like all our Earth Shield® waterstop profiles, and can be joined to our baseseal (or rearguard) profiles for intersecting joints.
