When deterioration has progressed to where the garage's structural integrity has been compromised, there is often no acceptable alternative to extensive restoration works. These works involve significant noise, dust, disruption, inconvenience, time, and finances to see through to completion. They are technically demanding projects that requires knowledge and experience in many disciplines, including but not limited to:
- concrete repair methodologies;
- materials, surface profiles, and compatibility issues;
- concrete formwork, falsework, and shoring systems;
- knowledge of building and garage electrical and mechanical systems;
While many contractors profess to be restoration experts, our experience has shown that most of these contractor's possess extremely poor technical understanding, managerial skills, and operate under a leadership vacuum. Predictably this lack in care and of skill results in poorly coordinated projects with large cost overruns, missed schedules, and frustrated parties.
In parking garages, reinforced concrete typically deteriorates after it has been contaminated with deicing salts. While the process of deterioration is highly technical, the impacts to your assets and operations are not.
An owner's most cost effective way of increasing the life of their parking garage is to install and maintain protective coatings and waterproofing membranes. These coatings act as barriers, blocking out salts so that they can't contaminate the underlying structure. There are many types of coatings and membranes, and thought needs to be put into evaluating and selecting the most appropriate one for a specific environment.
Waterproofing system types:
Rubberized asphalt, polyurethanes, epoxies, MMAs, matics, and modified bitumens.
Materials change in size with changes in temperature. It stands to reason that building's constructed from materials will do the same.
Building designers can't stop their buildings from moving, but they can decide where this movement occurs by strategically designing "joints" into the structure, typically referred to as "expansion joints".
While the rest of the structure stays more or less in the same place, the movement at these joints can be as much as several inches, making them notoriously difficult to waterproof effectively.
For this reason it is a necessity that you select a contractor that understands how these joints behave, who understands the different joint protection technologies available on the market, who gives near obsessive attention to their installation, and that has the experience to know the pitfalls and how to avoid them.
It doesn't matter what your budget is, or how complicated your project seems.

Once salts have permeated into you parking garage's structure it is a matter of time before affected areas need to be repaired. When the deterioration is caught before it has become large enough to significantly compromise safety and structural integrity, relatively minor, localised repairs, can significantly extend the life expectancy of the garage.
While it wasn't always the case, today concrete restoration is a mature industry with well established protocols and methods for repairing deteriorated concrete exist and provide long lasting results.
Typically, the first areas that show signs of deterioration include:
- concrete surrounding drain assemblies;
- concrete ledge beams (beneath expansion joints);
- bases of concrete columns;
- other low spots where water is allowed to sit.
