Crack Injection
Water Stop / Leak Sealing Crack Injection
and Structural Crack Injection
What is Crack Injection?
The process of Crack Injection involves injecting an adhesive chemical grout or resin to connect and seal a cracked foundation, slab or wall.
If left untreated, cracks in concrete structures will grow larger over time leading to more destruction and rebar corrosion.
Crack Injection, in infrastructure terms, is the application of a chemical grout, resin or bonding agent into a substrate to repair, seal, permeate and consolidate the substrate to extend the design life of a structure.
Crack Injection can be Grouped into Two Subcategories
The term crack injection, specifically concrete crack injection, covers a variety of injection techniques primarily used in infrastructure waterproofing repairs and structural concrete repairs.
Injection methods designed to prevent water ingress and migration are subcategory of crack injection known as chemical grouting — referring to the gels, resins and foams as chemical grouts. Chemical grouts include polyurethane resins and acrylic resins. These products are designed to work well in a wet environments. Water stop foams react on contact with water and expand to stop high velocity water flow. Polyurethane resins form semi rigid or flexible seals to permanently prevent water migration.
Powerful Polymers – Comparing Two Categories of Crack Injection Chemical Grouts
Hydrophobic and hydrophilic polyurethane based chemical grouts and structural epoxy based resins are the two major product groups used for crack injection. To better understand the characteristics and differences, please refer to our product comparison called ‘The Crack Injection Superheroes’.
