Structural Concrete Repair
As a Supporting Member of the International Concrete Repair Institute (ICRI), C.A. Lindman has worked with other leading consultants and contractor across the country to develop standards for the concrete repair industry. Personnel from Lindman have been involved since the early 90’s in the development of many of the repair guidelines that ICRI publishes as industry standards today.

The keys to concrete repair include removing all deteriorated concrete, exposing corroded re-inforcing steel, surface prep of exposed steel and concrete, proper treatment of the bond lines, and application of an appropriate patching material with similar properties to the original concrete.

Lindman has performed hundreds of diverse concrete repair projects each year since 1990, ranging from $10 million projects to $1500 projects. Every project is important to our clients regardless of size, and gets treated by Lindman as such.

Structure Concrete Repair

Epoxy/Chemical Injection
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.

Garage Repair
Concrete repair in garages have different challenges than from elsewhere in the building. Because most garages continue to operate, phasing plans and protection of parked cars are key ingredients in any successful garage repair project. If deck coatings are part of the project, many areas will have a concrete repair phase, and then later a phase for deck coatings.

In the mid-Atlantic and Northeast, much of the concrete repair is attributable to salts brought in on vehicles during the winters. Identifying and understanding chloride induced corrosion will lead to successful and long lasting repairs.

Repairs in garages often involve post-tensioned slabs, and can involve one way slabs, two way slabs, pan decks and joist decks. Occasionally garages will consist of combinations of conventionally reinforced areas and post-tensioned area, and/or combinations of the different slabs and decks outlined above. While the basic method of concrete repair is the same, structural support, formwork, and other approaches and costs are not.

With Lindman vast experience on hundreds of garage repair projects, we can simplify even the most complex garage repair project, balancing cost with lost parking, and phasing with overall schedule.

Balcony Repair
Repair of balconies can include concrete repair, railing removal/reinstallation or replacement, deck coatings, replacement of caulk and repair of adjacent brick, dryvit or other exterior wall finishes. Two issues are unique to balconies.

The first is the extreme proximity to the owner's living quarters. With all of the potential activities listed above taking place within feet of the living quarters, a consistent systemic approach to these repairs is critical to the success of the project.

The second is the connection of a thin slab of concrete to a typically metal railing. The connection detail, typically embedment with grout, is the most common area for deterioration of concrete to start. Modifying these details as part of the repair has over the years lead to longer term repairs.
