While it is true that all the buildings need regular maintenance, the parking garages need a bit of extra attention. They are subject to extreme conditions than most of the structures. They are not only exposed to the vehicle traffic, but also to temperature or moisture changes from weather. Therefore, they need proper maintenance programs to prolong their lives as well as to protect them.
Some of the common Parking Structure Issues
Most of the structural deteriorations that are faced by parking garage are due to corrosion of embedded materials. It results from long term exposure of it to moisture and other chlorides from the salts. When the chloride and water penetrate into the concrete in the sufficient concentrations, the metals in it start corroding.
Another widespread issue is the cracking of concrete. In some of the instances, the cracking is normally related to the applied loads. Such cracking can result in a direct path for chlorides and moisture to enter the concrete floor slabs.
Protecting parking structures by waterproofing strategies
If your condition of parking is too deteriorated, there are several ways in which it can be repaired or can be protected. For instance, if you have a new garage with minimal of the chlorides in concrete, it can be benefitted by applying penetrating sealer.
However, this sealer may not be an adequate protection for older garage that is experiencing spalling of concrete or corrosion-related delamination. In garage having significant amount of the cracking in the floor slabs, a traffic bearing membrane system can be good since it has crack-bridging capability.
Cost is another important factor while choosing an appropriate system. For example, applying silane sealer may cost 1/3rd of the cost as compared to application of membrane system. So, most of the managers select sealer if more effective protection isn’t needed.
However, while considering the long term cost, a membrane system can be a good option. It can offer 15-20 years of service life.
Proper routine maintenance is also essential to maintain the structure well. Structural maintenance includes tasks directly affecting garage structure. It includes patching and repairing areas of the spalled or delaminated concrete on the ceilings and floors, cracks in the floors, sealing joints, and much more.
Thus, parking garages need regular inspection, repair and maintenance. Make sure to follow the above guide and consider protecting the parking garages with effective waterproofing coating by Soprema waterproofing to maintain its good condition for long.
