Polyurethane crack injection kits are recommended for non structural leaking cracks resulting from concrete shrinkage or minor settlement while epoxy injection kits are designed to treat more severe cracks that compromise the structural integrity of the wall.
How to injection concrete wall cracks with epoxy.
Concrete cracks are repaired using different techniques and methods such as epoxy injection depending on how wide long and or deep the crack is.
Prior to doing any injection it is necessary to determine the cause of the crack.
It can be used for low pressure injection of cracks in structural concrete and solid masonry.
The crack pac two part high solids low viscosity crack injection epoxy is designed to repair cracks in concrete.
3 when filling wide cracks wait some time not a lot ensuring that the epoxy is filling the concrete crack.
The mixed adhesive has the viscosity of a light oil and a low surface tension allowing it to penetrate fine to medium width cracks in dry damp or wet conditions with excellent results.
As strong as concrete.
Epoxy injection is an economical method of repairing non moving cracks in concrete walls slabs columns and piers and is capable of restoring the concrete to its pre cracked strength.
Ideal for foundations floors columns slabs and beams.
Sikadur crack weld injection kit is a two component fast curing epoxy sealing system for repairing structural cracks in concrete and masonry.
Simpson strong tie offers reliable easy to dispense products for a variety of restoration applications including structural restoration pick proof sealing and water intrusion prevention.
The high pressure injection of activated polyurethane uses an electric injection pump and packers hammered into drilled holes through the crack in a poured concrete foundation wall.
Like epoxy the injected polyurethane fills the crack through the entire thickness of the foundation wall typically 8 thereby preventing water from entering.
1 start with a low pressure injection setting and increase the pressure as needed.
2 larger cracks require more epoxy injection pressure.
4 remove the top seal using a chisel or scraper.
