The Fischer heavy-duty fastening set includes mortar, anchor sleeve and anchor rod, everything you need for stable and permanent fastening in masonry. The composite mortar is based on a vinylester hybrid base with an extended curing time, which prevents premature curing even in summer temperatures. Resin and hardener are stored in two separate chambers and are only mixed and activated when pressed out in the static mixer. The injection mortar is also suitable for large borehole depths. This system makes it possible to reuse opened cartridges by changing the static mixer, which is also included in the scope of delivery. The heavy-duty fastening set from Fischer can be processed without special tools using a standard silicone squeezer.
