TWO COMPONENTS HIGH STRENGTH POLYURETHANE RESIN SOIL STABILIZATION & REINFORCEMENT WEAK GROUND
INTRODUCTION
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:
Soil stabilization.
Improve weak underground substrate.
Increase strength of soil underground.
Lifting ground concrete slab.
Water barrier for concrete structures attached to the ground or soil.
Crack sealing on concrete structures.
Sealing on construction joint leakage.
ADVANTAGES
Permanent seal which provide longer life time than conventional concrete.
Very high strength.
Low viscosity that can penetrate into very small voids.
Good bonding to concrete and brick/block.
High chemical resistance to almost underground chemicals.
Hard and tough material.
Can do both wet & dry crack.
It is non-permeable material.
Adjustable reaction.
Total 100% solid & non-shrinkage.
Non-toxic once cured hard material. Can use with potable water (cured material).
Non-corrosive with steel or concrete.
APPLICATION AND INSTALLATION
PREPARATION
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.
MIXING
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
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.
FINAL WORK
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).
PACKAGING
Part A: 19 kg.
Part B: 21 kg.
STORAGE
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
