Epoxy Injection Crack repair


Creative concrete and cutting provides crack repair for all kinds of concrete . Traditional methods and special methods are used to finish the job according to the specification. The epoxy injection is an advased method of repairing a crack in its early stage. This kind of crack repairing is mostly done in roofs and walls to prevent them from further cracking and filling the cracks with a solid epoxy fills. – PowerPoint PPT presentation

Title: Epoxy Injection Crack repair

Guide to Epoxy Injection Crack Repair
Concrete Crack
  • Concrete cracks can be caused by several reasons
    including improper construction methods and
    material composition. As concrete ages the
    cracking is normal and it can be repaired by
    using various methods including Epoxy injection
    which we will be explaining in this guide.

Epoxy Injection
  • Epoxy Injection is the method of injecting epoxy
    into the crack in the concrete to fill up the
    gaps and stick the concrete together for a long
    life of concrete. The cracks are filled with
    epoxy as it flows and fills the cracks when
    applied pressure via ports.

  • As shown in the images the cracks are fitted with
    ports for epoxy injection then the crack is
    sealed to avoid epoxy leakage. When the seal
    dries and all ports are in place the epoxy
    injection is started using Bottom-Up approach for
    better results.

Steps of implementing epoxy injection
  • Clean the cracks
  • Install the entry and venting ports
  • Seal the surfaces
  • Mix the epoxy
  • Inject the epoxy
  • Remove the surface seal

Clean The cracks
  • Cleaning a crack is necessary. It is primary step
    because it ensures successful epoxy injection.
    You can use Blowers, Vacuum or other traditional
    method to clean a crack. If there is Moss in the
    Crack you can use blowtorch to burn it. After
    that use blower and vacuum to finish the cleaning.

Install the entry and venting ports
  • Installing the entry and Venting ports is
    important. The optimal distance between two ports
    depends on the width of the crack if the crack is
    very thin you can use ports at a longer distance.
    But no more than 6 . The venting ports are
    necessary to allow the epoxy to flow.

Seal the surfaces
  • The sealing is necessary to avoid spilling of
    epoxy when injecting in the cracks. The cracks
    can be sealed using polyester polymer or epoxy
    any of them can be used to make a solid seal. The
    cracks are sealed properly and the gap between
    the ports should also be sealed.

Mix The Epoxy
  • Mixing of the epoxy should be done according to
    the manufacturer guide lines. The amount of epoxy
    should be decided according to the work need.
    Mixing extra epoxy is never good. As it will be
    plain waste if not used in time.

Injecting Epoxy
  • Injecting epoxy is the work of patience. Start
    from bottom ports and move upwards to ensure
    there are no voids or bubbles in the epoxy. Epoxy
    flows slow so wait until it comes out of an upper
    port. Close the port you have finished.

Remove the surface seal
  • After the epoxy is injected wait for it to settle
    and dry. After few days you can remove the seal
    by using chisels or grinders the ports will come
    out easily and you can then apply a final seal
    over the repaired part to fill up any defects
    while removing the seal.
