The Hilti HVU2 is a new foil capsule chemical anchor that suits the needs of even the toughest jobsite conditions. The flexible capsule comes with a simple and clean installation system. Significant upgrades in technical data covering cracked concrete and diamond coring help ensure that it can be used in a variety of high load applications.
Hilti’s new HVU2 enables users to move from the old style glass capsules to unbreakable foil capsules. The Hilti HVU2 foil capsules ensure that just the right amount of adhesive is used in every anchor hole. These flexible capsules are extremely convenient for overhead installation as they even fit into irregular holes without dropping out.
The capsules are easy to install, with a precise dosage from each capsule keeping mortar waste to a minimum and reducing the need for volume calculations. Every package of Hilti HAS rods in the sizes M8 to M16 contains a setting tool for setting HVU anchors using either a drill driver or hammer drill.
The HVU2 capsules ensure reliable installation thanks to mineral grit, including corundum, which shreds the capsule foil in every drilled hole. This hard abrasive material also helps roughen the drilled hole so that installation is successful without need for additional roughening of diamond drilled holes or brushing out hammer drilled holes.
All it takes is five minutes at a temperature of 20ºC or above for the adhesive to cure and establish a bond that can take the full load. No time is wasted waiting after installation.
Minimised design effort
The HVU2 foil capsule system is integrated as a design option in the Hilti PROFIS anchor design software. This means that if designers use HVU2, the software includes an option to check whether the design is also suitable for use of HVU2 foil capsules. The solution is displayed in the design report as an alternative and can reduce design effort significantly right from the start.
Reliable under real jobsite conditions
Conditions on jobsites can be harsh. If chemical anchors are used, they must therefore resist exposure to the rays of the sun and damage from dropping or other impacts. Hilti HVU2 foil capsules have not only been tested under extreme jobsite conditions, the elasticity of the resin used also helps ensure that the anchors specified in the design meet the calculated values.
More economical
Depending on the number of fastening points required, HVU2 foil capsules may be more economical compared to injection systems. This is because capsules require no additional installation equipment for precise dosage and when fastening overhead.
Technically advanced
When it comes to technical advancement, Hilti states that HVU2 is in a league of its own. HVU2 ensures high load capacity in both cracked and non-cracked concrete and in diamond cored holes.
