Rockmax PU600 is a solvent free, two components polyurethane injection resin. Cured material results high compressive strength, bonding and tensile strength. Its very tough and solid. It is recommended to use specially for soil stabilization, reinforcing behind concrete structure, protect water infiltration to concrete structure, sealing cracks, filling cavities and gravel nests.
AREA OF USES
water barriers and curtain injections. Range of application include:
APPLICATION AND INSTALLATION
The soil structural or concrete structure analysis must be carried out prior to process the injection. The extent of the examination and application method depends on the conditions on site. The nature and state of the soil structure must be determined.
In case of high water pressure, it must be stop water by inject Rockmax PU100 or Rockmax PU200 prior to start inject Rockmax PU600. Remove the loose materials from the surface of the cracks. Drill the injection holes and Install the metal packer along the cracks line. Tight it by wrench and ready to injection.
Mix part A and part B by low speed mixer (400- 500rpm) for 2 minutes until homogeneous. Place the material into the bucket and ready to inject.
APPLICATION (1-coponent injection)
The works must be carried out by experienced and trained contractors. Use single component pump for inject the resin though the cracks. Pour the mixed resin in to the bucket ready to injection. Inject from bottom to top. Re-inject again to ensure the area is fulfilling by material.
APPLICATION (2-coponent injection)
Place the material each part on each component of injection machine. Adjust the rate of each bucket as per design reaction time. Ensure the volume flow is sufficient so that part A and part B are mixed homogenously in the mixing device.
Curtain injection for below grade structures it is recommended to drill through the structure in pattern that is determined by the physical of the soil. Standard pattern hold are approximate 40 to 50cm spacing.
The packer can be removed immediately after the gel formation. Mechanical packers cleaned by means of rinsing pump can generally be used again. After dismounting the packers, remove all gel from the drill holes and fill with concrete repair mortar (Rockmax TOP) or quick setting cement mortar for brick work (Rockmax Waterplug).
Part A: 19 kg.
Part B: 21 kg.
Storage in shade and dry condition free from frost, water, moisture and high temperature. Rockmax PU600 must be store in air tight container. Must be protected from atmospheric moisture. Must be store in area where temperature around +10ºC to +30ºC degree. All open container should be
