The company’s line of high-performance A7 products has been expanded with a new 10-oz. system designed to fit a standard caulk gun. The A7-10 acrylic adhesive cartridge was developed for small jobs requiring a fast curing adhesive anchor, the manufacturer notes.

Utilized in stadiums, roadways and bridges nationwide, the A7 acrylic adhesive line also features 5-, 8-, and 28-oz. cartridges. The A7 suits rebar dowelling, sill-plate anchoring, anchoring heavy equipment, and structural steel. Product developers cite the following benefits:

  • Fast curing Û Cure time is 35 minutes at 60_F.
  • Quick dispensing Û All systems, including 28-oz. cartridge, can be dispensed by hand.
  • All-weather formula Û The adhesive can be used in zero-degree weather without a heating cartridge and works even in damp holes or underwater locations.
  • Easy cleanup Û No drip or sag formula provides mess-free anchoring.
  • One formula Û System is suitable for both hollow and solid base materials.
  • Requires less adhesive Û For rod size ?-in. and larger, drill bits can be used that are 1/16- or ?-in. over rod diameter.

Installation requires drilling a proper-sized hole, cleaning it thoroughly, inserting nozzle directly into the bottom of the hole, and filling to half the hole depth. The acrylic resin and hardening agent are mixed as they simultaneously are dispensed from the dual cartridge through a static mixing nozzle. The selected rod (threaded rod or rebar) is then inserted by hand, slowly rotating it into the bottom of the hole. The fixture is tightened into place after the cure time is met. ITW Red Head

As American Concrete Institute guidelines and related code changes require longer lap lengths in masonry construction, the manufacturer cites two solutions for contending with increased masonry cell rebar congestion: open-cell blocks or mechanical couplers to eliminate the lap. Accordingly, the Lenton taper-threaded splice has been designed to connect two pieces of rebar.

The connector uses a taper thread for assured strength, consistency and reliability, the manufacturer notes. Meeting ACI-318, BS 8110 and DIN 1045 full-tension splice requirements and international specifications, the splices are tailored for use with worldwide standard grades of rebar. Available sizes range from #3 to #18 (10 mm-57 mm). Manufacturer-cited benefits of Mason Lock taper-threaded splices include: elimination of lap splices in CMU block walls; acceleration of construction schedules; installation ease due to the taper-thread design; allowance for future extension applications; and, structural integrity.

A specialist in structural masonry retrofit strengthening, repair, and preservation, Cintec America, Baltimore, promotes a earth-retaining stabilization system to tie back historically sensitive walls or wherever the historic nature of a structure has to be preserved. The versatile system, company officials contend, offers a solution tailored to each job’s requirements.

For over 20 years, Cintec has provided technology to stabilize and restore structures worldwide, including historical landmarks, harbor and sea walls, museums, churches, and bridges. The first such application in 1983 involved the use of Seadoos anchors to tie back a protective sea wall in Florida. The system is suitable for difficult ground conditions, including sand, gravel, clay, limestone, as well as broken brick and stone.

The process begins with an inspection by the client’s engineer, who assesses the problem and relays all relevant data to the company for review. Suggestions respecting the original structure and ground conditions are then provided. At the site, ground anchors provide stability, while voids and gaps within the structure are bridged using a cement-like grout. Û 800/363-6066


Compliant with ASTM C 1620-05, the industry’s first specification for aerosol foam sealants, the new CF 812 and CF 810 Filler Foams offer an alternative to traditional sealing methods. The manufacturer notes that both products are suitable for restricting air, sound, dirt and water infiltration in a variety of applications.

Useful primarily for sealing window and door-frame perimeters (tested in accordance with AAMA 812), the CF 812 Window and Door Pro is low-pressure filler foam that also can be used for sealing openings where flexible material is needed. The CF 810 Crack and Joint Pro is reportedly a high-performance, high-yield foam for such general gap/crack applications as insulating around electrical outlet boxes, filling openings around HVAC ducts, and sealing pipe and cable penetrations.

The products help save energy by reducing air infiltration and also provide a sound-reduction barrier. For precision installation, the foams are used with the company’s Premium DS-1 dispenser, whose valve is said to prevent pressure loss, prolong shelf life, and eliminate waste. Hilti

Pigment, admixture and reinforcing fiber manufacturer Interstar Materials, Sherbrooke, Quebec, is the recipient of the 2005 Canada Export Award for Research & Development. Export markets account for 53 percent of sales, a significant statistic for the company, says Interstar President Zachary Gillman. Having established itself as a leader in the Canadian market, Interstar decided to increase its exports to ensure strong and healthy long-term growth.

Interstar’s exporting success is credited in part to its adherence to the principles of Lean Six Sigma and its commitment to the environment. The manufacturer’s emphasis on research and development, plus safety and staff training, also contributes to its growing world trade, which has seen the company enter American, Mexican and, most recently, Brazilian markets.


A National Institute for Occupational Safety and Health (NIOSH) finds that 1) manually tying rebar at ground level using pliers and wire involves sustained deep trunk bending and rapid and repetitive hand and wrist movements; and, 2) using a battery powered tier significantly reduces the use of rapid and repetitive hand-wrist and forearm movements characteristic of tying with the pliers, and frees one hand to support the weight of the trunk during tying.

Rebar tier manufacturer Max USA Corp. in Mineola, N.Y., notes that the study involved a NIOS Health Hazard Evaluation for Baltimore-based Genesis Steel Service, a construction reinforcing and structural steel contractor. Agency staff evaluated the risk that GSSI reinforcing ironworkers have for developing back and hand musculoskeletal disorders as a result of hand-tying reinforcement steel on concrete bridge decks and other large slab jobs. They also investigated whether the use of a Max battery powered unit for rebar tying can help prevent work related musculoskeletal disorders of the upper extremities and back.

According to Max USA, NIOSH representatives found that adding an extension handle to the battery powered tier allowed workers to tie rebar standing erect. Study results also show that manually tying rebar, using pliers, involves greater risk of developing a lower back work related musculoskeletal disorder than tying with either the battery powered tier, with or without the extension. The study indicates that tying with the battery-powered unit and extension arm also involves less risk of developing an upper limb work related musculoskeletal disorder.
