Poly Wall Injection Epoxy LV
Poly Wall Injection Epoxy LV is a two-component, %100 solid, moisture-insensitive epoxy resin system which has a high modulus of elasticity. Poly Wall Injection Epoxy LV is formulated to meet ASTM C-881 specifications. It is unique in that it rapidly thickens in the crack so that material cannot leak out the back for more than 10-20 minutes (unlike conventional products which can flow out hours after injection). You can now confidently replace whatever may have leaked out in those twenty minutes knowing that no more can leak out, unless the initial injection has leaked out the back of the crack within 20 minutes (unlikely to happen). This overcomes the common epoxy crack repair failure, namely the incomplete injection of epoxy into a crack arising when material leaks out the back of a crack after injection.
Uses
- A) Structural repair of cracked concrete by pressure injection, grouting.
- B) Monolithic restoration of laminated concrete.
- C) Grouting material when mixed with aggregate.
Surface Preparation
- All surfaces must be clean and free of dirt, dust, oil, grease or any contaminant that could adversely affect the bond of the surface seal. Surfaces must be structurally sound. Surfaces may be dry or damp. However, due to the many variables in bonding damp surfaces, be certain to make a test application under the conditions as the full scale work.
Application
- Injection Pressure: The material can be injected into cracks down to 0.002 inches with pressures ranging from 20 to 300 PSI. Inject through plastic ports. Depending upon the depth of the slab, place them every 6" to 2' along the length of the crack. Wherever possible, seal all surfaces of the crack. When dealing with hydrostatic presser, hydraulic cement should be used to control the water flow and seal the crack.
- Begin injection of the mixed with the lowest port or at one end of the crack. Continue pumping until resin flows from the next port. Then seal the first port and move onto the next one using the same procedure along the length of the crack.
- Gravity: "V" out the cracks. Blow and clean out thoroughly with oil-free compressor air. Fill the cracks with RESIN. More than one application may be required.
