MASTERROC EQ 558 PK MECHANICAL PACKER 5/8" GREEN

The MasterRoc EQ 558 PK mechanical packers are zinc-coated steel mechanical packers with a greasy kind fitting   They are intended to be used in highly pressurized polyethylene as well as other synthetic sealant injection applications to prevent leakage of water. MasterRoc EQ 558 PK mechanical packers in highly pressurized chemical grout injection can be used for repairing cracked concrete pillars. MasterRoc EQ 558 PK mechanical packers is also helpful in halting or decelerating water flows through small cracks in reinforced cement concrete. MasterRoc EQ 558 PK mechanical packers can be injected in previously repaired concrete cracks that require additional chemical waterproofing. Sealing hurricane pipe, drainage ditch joint capsules, power vaults and drainage channels are all other applications of MasterRoc EQ 558 PK mechanical packers. Uses: Drill a hole into the concrete at an angle of 45� to the surface.The depth of the hole should be approximately one half ofthe thickness of the concrete, drilled away from the center ofthe crack. The hole must intersect with the crack towards thecenter. The size (diameter) of the hole is determined by the sizeof the packer (1/2 in. (13 mm) or 5/8 in. (16 mm) Flush drill holes with water before inserting the packers Place the packer into the hole (with the sleeve going in firstand the grease connector facing outside). The top of the sleeveshould be just below the concrete surface. Secure the packer inplace by tightening with a wrench until it is snug fit. Do not overtighten the parker, as this may stress weak concrete and causea leak around the packer Space the holes/packers approximately 6 in. to 3 ft (150 mm to 900 mm) apart, depending on the width of the crack Flush the cracks by injecting clean water through each packer prior to injecting chemical grout, to flush any contaminants and to facilitate good bonding of the chemical grouts. Begin the chemical grout injection at the lowest packer on vertical cracks, working up or on one side on horizontal cracks, working across Injection pressure may vary from 250 to 2500 psi (1.7 to 17 MPa), depending on the width of the crack, thickness and the condition of the concrete Continue injecting till the grout appears at the adjacent packer. Then stop injecting, disconnect from the packer, and move on to the next packer Once chemical grouting is completed, reinject each packer with clean water to cure the grout Once the chemical grout is cured, remove the packers by unscrewing or pulling them out or simply breaking off Fill drilled packer holes with an approved cement mortar or epoxy gel type material
