Ingro-652

DESCRIPTION:

AT-INGRO 652 is a two component, solvent free, low viscosity injection system, based on high strength epoxy resin. It is suitable for injecting into cracks, honeycombs and cavities in concrete structures. It is recommended for grouting of 0.10 mm to 4.00 mm wide cracks, cold joints and other undesirable cracks. Post mixing, it is injected into cavities / cracks in concrete where it cures to form a rigid, high strength material. STANDARDS: It complies with ASTM C 881 – 87, Grade I, Class B + C

USES:

• AT-INGRO 652 is used to fill and seal cavities and cracks in concrete structures such as:
  • Columns
  • Machine bases
  • Beams
  • Foundations
  • Decks
  • Water Retaining Structures

ADVANTAGES:

• AT-INGRO 652 is a low viscosity penetrative liquid with high adhesive qualities. Other benefits are:
  • Solvent Free
  • Suitable for both DRY & DAMP conditions
  • Usable at low temperatures
  • Shrinkage free hardening
  • Does not lead to embrittlement
  • Two component pre-packed system – easy to mix and apply

INSTRUCTION FOR USE:

• SURFACE PREPARATION
  • The concrete surface must be hard, sound and free from dust and other barrier materials such as paints, lime coatings, plaster, curing agents, laitance adhesive residues, etc., 2-3 cm on either side of the crack that will inhibit the adhesion of the substrate.
  • Use appropriate pneumatic drills for making suitable holes and fix the nipples or injection packers. Ensure that the holes are free from any debris and laitance before fixing the packers or nipples.
  • Use suitable adhesive for fixing surface port or nipples in position.
  • The distance of the ports or nipples depends on the crack severity and the nature of the structure but with minimum centre-to-centre distance of 800 mm. Close the whole length of crack opening using suitable adhesive.

• MIXING
  • Mix both the components together in right proportion for at least 2 minutes with a recommended stirrer and electric hand drill at a slow speed (max 600 rpm) until smooth consistency and homogeneous mixture of uniform colour is achieved.
  • Proper care has to be taken so that no air is entrapped due to mixing.

• APPLICATION METHOD
  • Various application methods are practiced with different equipment requirement, depending on the nature of the work to be carried out.
  • Generally automated inject equipment or manual method is used.
  • Set appropriate injection ports based on system used. Inject AT-INGRO 652 with steady pressure after adhesive seal has been cured.

• IMPORTANT RECOMMENDATIONS
  • Minimum and Maximum crack width for application: 0.10 mm & 4.00 mm respectively.
  • Minimum age of new concrete : 3-6 weeks
  • Not to be injected under hydrostatic pressure

• CLEANING
  • All tools and equipment should be cleaned immediately after use. Hardened / cured material can only be mechanically removed.
