Steps to get your concrete crack repairs and fixing done to perfection

  • To start with, utilise a wire brush to clean the crack. Clear any loose debris that is present and then vacuum the crack to get all the dust removed. Ensure that there is no grease, oil, or dirt remaining in or close to the crack if any, then clean it all together.
  • The next step is to use a chisel and a hammer to undercut the edges of the crack. This will keep the patch in place. Make certain to wear your safety glasses while performing the procedure.
  • Take your paintbrush and cover the cracked surface with the help of a concrete bonding adhesive and let it dry completely.
  • Then blend an appropriate amount of sand mixed with water.
  • Using a trowel, ensure that you cover the crack thoroughly with the mixture.
  • Once filled, remove any excess mixture, and level the surface and allow the patch to be cured without any disturbance.

Injections Are a Good Choice for your concrete crack repairs and fixing

  • They help you keep away from costly expenses for your structural repairs and reduce the time to get the job completed.
  • They can be utilised for all kinds of crack and leakage sealing in concrete, masonry, and foundation structures.
  • They provide a permanent watertight sealing solution to your structures.
  • They can be utilised at the beginning of the construction or later stage to increase the durability and reliability during any subsequent repair or remodel of the structure, as per the project’s requirements.

Successful Waterproofing using Injection Systems

Injection Material

The choice of the correct injection material and the correct injection item for the defined project needs is the fundamental key factor for the project’s success. The material’s viscosity, adaptability, and way it behaves when it comes in contact with water are particularly significant – everything which can altogether impact the viability of the injection.

Injection Equipment

The second most crucial factor is the correct equipment for the injection material you have chosen to make the correct material, blending, and delivery arrangements. This incorporates the initial measurements, blend, and delivery from the appropriate pump to utilise the right packers/ ports/ connectors.

Injection Technique / Application-

Lastly, the correct injection technique and application must be followed by professional, skilled, and experienced workers to ensure success and provide a permanent leakage sealing solution for your structures.
