A wall spear packer is a reusable grout injection device which connects the grout hose to a concrete or rock surface. The device is available in a variety of sizes, valve options, and body metals depending on the type and volume of grout to be injected. When anchored in solid concrete or competent rock, the device is suitable for relatively high volumes and injection pressures as well as a variety of grouts including urethane, silicates, cements, acrylates, and acrylamide. Gel grout is easily removed from the spear after injection using a stiff wire and compressed air. Carbon steel is suitable for all urethane grouts. Use stainless steel for acrylamide, acrylate, and other caustic or acidic materials.
