Bonded anchor cartridge systems offer a variety of unique benefits compared to mechanical anchoring techniques. By avoiding mechanical expansion, they introduce no stresses into the substrate and can be installed close to each other and to substrate edges. They also resist high static loads, with some products formally approved for seismic applications. Most resin anchors may be used in a wide variety of substrates and site conditions. If the substrate is hollow, bonded anchors may still be used in conjunction with perforated sleeves.
