Concrete cracks. No one likes it, but it is a fact. These cracks create structural concerns and waterproofing issues.
Chemical injection is used for stopping water penetration through cracks in concrete walls and slabs. The most common use is for walls or slabs with soil on the opposite side of the wall or slab from the leak. The removal and replacement of soil to install a membrane is prohibitively costly. There are many types of chemicals that have been developed for these uses. Most use an activator to expand the gel once in the crack in the concrete. Expansion of 300 per cent by volume is possible with current technology.
Epoxy Injection addresses the structural concerns by acting as a glue-like substance in the crack. This is commonly used in structures that incurred a one time loading or movement event. This type of repair will not be effective in areas of repetitive thermal movement induced cracks.
Either technology is a much an art as a science. The key to success is in the hands of the craftsman performing the work. Lindman is proud of our personnel and the grouting and injection experience they bring to our team, and your project.
