Less waste and higher reliability with the Hilti HVU2 ultimate-performance foil capsule for chemical anchor fastenings in concrete

A rebirth of the classic: 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.

1 / 4

It’s time to switch from old-style glass capsules to unbreakable foil capsules. Our 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 fit even in irregular holes without dropping out.

2 / 4
Easy to install

Precise dosage with each capsule keeps mortar waste to a minimum and reduces the need for volume calculations. Every package of Hilti HAS rods in the sizes M8 to M16 contains a setting tool for setting HVU2 anchors using either a drill driver or hammer drill.

3 / 4
Reliable installation

Mineral grit including corundum ensures reliable shredding of 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.

4 / 4
Instant curing

All it takes is 5 minutes at a temperature of 20 °C or above for the adhesive to cure and establish a bond that can take the full load. No time is wasted waiting after installation.

Minimized design effort

The HVU2 foil capsule system is integrated as a design option in our 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 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 such as HIT RE 500 V3 and HY 200. This is because capsules require no additional installation equipment for precise dosage and when fastening overhead.

Technically advanced

When it comes to technical advancement, HVU2 is in a league of its own. HVU 2 ensures high load capacity in both cracked and uncracked concrete and in diamond-cored holes.
