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.

Overview

• 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

7
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.

8
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.

9
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.

10
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.

11
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.

12
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.
