Issues

  1. Are you unable to find the source of water in your walls causing seepage ?
  2. Are you tired of repeated repairing and re-waterproofing due to paint peeling, surface cracks, mold, and fungus growth due to dampness? 
  3. Have you noticed your walls sweating or seeping moisture through after heavy rains despite using traditional waterproofing solutions? 

Presenting Star Leak Proof Epoxy —to achieve a watertight structure

Star Leak Proof Epoxy - is a two-part, low viscous, injection grout composed of epoxy resin and a hardener system formulated specifically for crack injection work, to be placed by free flow under gravity, or may be injected using a suitable hand or mechanical pump. The injection grouting system provides rapid strength gain, has excellent penetration due to its low viscosity, and helps the concrete obtain mechanical properties several times those of premium concrete. Due to the expandable nature of Star Leak Proof Epoxy upto 40 times, it completely seals concrete pores, capillaries, and cracks. The hardened grout is resistant to water ingress, stable in seawater, and impervious to freeze-thaw cycles. It is also resistant to most chemicals.

Magical Benefits of using Star Leak Proof Epoxy 

  • Water resistant

    Star Leak Proof Epoxy fills the voids and capillary pores in concrete, making it impervious, water tight and resistant to water ingress. It even withstands high hydrostatic pressure.

  • Low viscosity

    Star Leak Proof Epoxy has deeper penetration due to its low viscous properties, it easily penetrates into the finest of cracks, ensuring thorough filling and pore blocking of concrete.

  • Non-shrink

    The basic characteristic of cement is that it causes concrete to shrink, which is a drawback in many applications. These can be compensated with use of Star Leak Proof Epoxy, as it maintains volume stability and imparts non-shrink properties.

  • Chemical Resistant

    Concrete injected with Star Leak Proof Epoxy becomes impervious, resistant to acid, chemicals, and toxics, and helps in maintaining the pristine condition of the structure.

  • Corrosion resistant

    Star Leak Proof Epoxy blocks the pores in concrete and also has excellent adhesion to the reinforcement, which makes the structure resistant to corrosion. It can also be used in prestressing and post-tensioning applications without fear of tendons corroding.

  • High mechanical strength

    Concrete injected with Star Leak Proof Epoxy imparts high mechanical strength as it makes the substrate impervious. This makes it an excellent choice for applications requiring durable and robust repair.

  • Structural support

    Suitable for structural support where thin section grouting is required. It also helps in faster strength development without the need for additional curing agents.

  • Excellent adhesion

    Star Leak Proof Epoxy imparts excellent adhesion to all contact surfaces, which is crucial for structural integrity.

USP 

Versatility: Star Leak Proof Epoxy offers a waterproofing solution that can be used in various applications. Whether it's a roof, terrace, balcony, bathroom, water tank, or basement, this product can effectively make the structure watertight. Excellent choice for structures, particularly in challenging environments where durability and strength are paramount. 

Where to apply 

  • Rehabilitation works

  •  Basements

  • Retaining wall 

  • Terrace

  • Hairline wall Cracks

  • Concrete planter Boxes

How to apply

  • SURFACE PREPARATION

    1. Water ponding test or thermal imaging of the substte should be carried out, and leak points should be marked.
    2.  Grooves of small sizes should be drilled on the negative side to place G.I. nozzles at definite intervals.
    3. Measures to be taken to lightly block subsequent G.I. nozzles while pressure grouting in order to ensure complete pore filling of concrete.
  • Protect industrial roofs with Star Water Seal - Industrial: Ideal for internal, and external applications.

    MIXING

    1. Prior to mixing, shake Star Leak Proof Epoxy Part A and Part B briefly until homogenous, then pour both parts into the mixing container and thoroughly mix and stir for at least 2 minutes using a slow speed (300-400 RPM) drill machine attached to a mixing paddle. 
    2. Retempering with water or solvent should not be done. Keep on stirring during application to ensure grout does not contain lumps.

  • APPLICATION

    • G.I. nozzles shall be fixed at leak areas at definite intervals and mixed Star Leak Proof Epoxy shall be pressure grouted
    • During pressure grouting keep polymer-modified mortar ready to block the tip of G.I. Nozzle.
    • Star Leak Proof Epoxy can be pressure grouted manually or mechanically.

Advantages and Disadvantages of Epoxy Grout

  • Advantages

    • Durability: Withstands thermal tension and soil pressure.
    • Stability: Provides a stable foundation for repairs.

  • Disadvantages

    • Curing Time: It takes longer to cure (over an hour at room temperature).
    • Cost: More expensive than cementitious grout.

Working principle

  • Star Leak Proof Epoxy Injection grouting is a method of filling the cracks, open joints, voids, or honeycombs, in concrete or masonry structural members. This is done under pressure with a grout material that cures in place to produce the desired results, like improved compressive, tensile, and flexural strength of concrete and preventing water ingress. Star Leak Proof Epoxy is a flowable material which has negligible shrinkage to fill gaps or voids and remains stable without cracking, delamination, or crumbling. They are used for waterproofing and the repair and strengthening of concrete and masonry structural members.

  • Its application includes-

    • Reduce or fill the cracks on surface
    • Repairing the cracks in walls columns
    • Providing smooth finish to the wall by filling honeycombs
    • Settlement of foundation
    • Repairing the damage in the structural or masonry members
    • Making structures watertight
    • Avoiding seepage of water in stone masonries
    • Strengthening tunnel linings
