Crack Injection - The Quickest and Least Expensive Basement Crack Repair
Crack Injection Explained
Foundation crack injection is a waterproofing and concrete repair method that is used exclusively for repairs to poured concrete foundations and/or underground structures, such as parking garages and underground utility rooms.
Crack injections are performed using two completely different techniques involving two completely different materials: epoxy, and polyurethane (sometimes referred to as urethane).
Why Crack Injection is a Leading Basement Crack Repair Method
Traditional foundation crack repair and basement waterproofing involved costly and destructive excavation, if the area requiring waterproofing or repair was accessible at all. Furthermore, exterior crack repair is far more time consuming than crack injection and involves a significantly greater lead time, because the location of underground utilities must be ascertained prior to excavation.
The cost and time involved for crack injection is a fraction of that for exterior excavation. Furthermore, it is not actually possible to repair, as opposed to waterproofing, a foundation crack from the exterior.

Epoxy Crack Injection
Epoxy crack injection involves the low pressure injection (typically 450 psi or less) of a blended epoxy resin and hardener into a foundation crack. This injection fills a foundation crack through the entire thickness of the wall with epoxy, which fully cures in the crack within 3 to 4 hours at 77°F. An epoxy injection crack repair is considered to be a structural repair because the strength of the epoxy bonding both sides of the crack exceeds the strength of the concrete itself.
Polyurethane Crack Injection
Polyurethane crack injection is usually, although not necessarily, accomplished at a higher injection pressure than an epoxy crack injection. Polyurethane crack injection is typically used in applications where waterstopping is the primary consideration or urgent. It is also the most common crack injection technique in use worldwide due to its versatility and its useability on actively leaking cracks. View the video below on polyurethane crack injection.
Limitations of The Use of Crack Injection
The popularity and relatively low-cost of crack injection makes crack injection an attractive basement waterproofing repair choice for many consumers; however, crack injection applies only to poured concrete foundations and structures. Concrete block foundations, because they are hollow, cannot be repaired using crack injection. Because concrete block / cinderblock is hollow, injected resins cannot be contained, containment of the injected material is essential to the success of any crack injection.
