STAIN-RESISTANT JOINT SEALANT For Aesthetically Sensitive Buildings Dow Corning 991 is a one-component silicone joint sealant with proprietary stain-resistant technology. It is now offered in North America as an alternative to the two-part Dow Corning 756 Silicone Building Sealant-H.P., due to industry's demand for weatherproofing sealants that resist staining of sensitive substrates and streaking on glass and metal curtain wall panels. The 991 sealant is a ready-to-use version that cures to a traditional semi-gloss finish. Its rapid tack-free time helps reduce dirt pickup, the company says.

CONCRETE PUMPING EQUIPMENT Overhead Roll-and-Fold Boom The new S61SX concrete pump features 198 ft of reach. The manufacturer claims it to be the longest boom pump in the industry. The four-section, overhead roll-and-fold boom is capable of reaching out, up and below grade with no dead spots. Because the boom's first section can be angled back, the other three sections can be guided into enclosed decks with ease. With the patented telescoping Super X outriggers, the reach and versatility of the equipment is capable even on a crowded jobsite. It maintains up to 1,169 psi for concrete. Schwing America Inc.;

(Photo courtesy of Jack Curran/ implosionworld.com) When baseball season begins this spring, Cincinnati Reds fans will enjoy a new $290-million stadium left unscathed from the implosion of its predecessor, only feet away. In 37 seconds on Dec. 23, contractors imploded Cinergy Field, formerly called Riverfront Stadium. After salvaging seats and other removable items, workers triggered the second step in a three-phase "green" demolition and environmental salvage operation. But they had to be mindful of the neighboring Great American Ballpark, under construction. Before the event, demolition workers protected the new park from projectile
Photo courtesy of Komatsu With product lines for hydraulic excavators well developed in medium-size classes, more buyers and manufacturers are exploring machines in the light and heavy ends of the spectrum. Komatsu America Corp. is no exception, replacing its 110-ton P1100 series with a new 125-ton PC1250 series of crawler excavators. Komatsu, Vernon Hills, Ill., considers the PC1250LC-7 its "flagship" construction excavator. Standard tracked, the manufacturer mounts the machine on a long-track carriage for increased floatation.
