INNOVATIONS EQUIPMENT & PRODUCTS SHIMS SUIT LARGE, HEAVY LOADS Large flat plate shims and micro-grid shims are the newest additions to Grove Products' line of solid structural shims used in con- struction, restoration and industrial instal- lation. The company manufactures shims out of 100 percent recycled plastic, and every shim style and size is available in fire- proof materials on request. Structural shims are used for a wide range of spacing and leveling applications, both on a temporary and stay-in-place basis. They are commonly employed in door, win- dow, and other glazing installations; for lev- eling very heavy objects such as tilt-up concrete walls, precast concrete panels and other large structural elements; and for lev- eling heavy machinery installations. "A shim is a humble but essential tool," stated David Braune, president of Grove Products, Inc. The large flat-plate shims, 8- x 8- x 1-in. thick, are designed to bear large heavy loads, with strengths up to 4,000 psi available. They've already been employed for leveling decks, structural members, and large, water-tanks. Micro-grid shims are de- signed to stack securely, using increased shim-to-shim friction due to mated grids on the shim's surfaces. The grid patterns inter- lock the surfaces of stacked shims to resist lateral slippage. They are initially available in 4 x 6 in. in thicknesses ranging from 1/16 in. up to 1/2 in. and can be stacked to ad- just heights with compressive strengths up to 6,000 psi. The family-owned Grove Prod- ucts is celebrating 50 years in business this year. — ARCHITECTURAL CONCRETE, GFRC ADMIXTURE A multi-component, powdered admixture, System 1 is especially suited to architectural precast and glass-fiber reinforced concrete. By combining six separate ingredients, the company notes, it simplifies production; at- tains uniform color intensity with dispersing and wetting agents; eliminates the need for liquid polymer when fabricating GFRC; and, closes the internal capillaries within the ma- trix, leading to a denser, more acid and stain resistant finished concrete. Through anti- foaming and anti-shrinkage agents, respec- tively, System 1 eliminates pinholes plus surface crazing, bowing, and curling when coupled with proper curing protocol. — Trinic LLC, 800/475-1975; WWW.CONCRETEPRODUCTS.COM APRIL 2012 | 43
