Concrete Repairs and Other Routine Maintenance Requirements for Parking Structure

Posted by Flexomeric on 1/4/2015

Buildings require constant check-ups and maintenance, but a parking structure in particular needs constant attention and scheduled maintenance. Whether it’s a private or commercial parking structure, it is often subjected to harsh conditions and the structure is regularly tested by heavy traffic and different types of vehicles. Also, a parking structure is subjected to changing weather and temperature, unless you are operating an enclosed facility. Because of these challenges, parking facility managers should incorporate maintenance and repair program that can protect and secure this investment for a long period of time. A recommended approach here is to come up with routine maintenance program that focuses on different aspects of the parking structure from floor to the ceiling. A complete maintenance program often involves concrete repairs, protective coating and crack and joint sealing.

Concrete flooring repairs

A parking structure accommodates heavy traffic of vehicles on a regular basis, thus it’s expected the concrete flooring is one of those parts that suffer first. Concrete will start to crack of delaminate from below, thus resulting to damaged and loose concrete. To repair the delaminated concrete, you’ll need to identify first the area. Usually, the repair area should extend by at least 3 in, and should be chipped put by at least ¾ in. The concrete edges can be saw-cut, making sure that the reinforcing bars are not damaged. If there are exposed steel and concrete surfaces, then these should be cleaned, with the reinforcing bars painted and properly coated. Once the coat has formed and cured, the concrete opening can be repaired using a commercial patching material or crack repair resin.

Joint and crack sealing

Cracks will normally show in foundation, walls and flooring and it’s critical that these openings should be addressed immediately to avoid the intrusion of chlorides and moisture.  Parking managers should be pro-active in maintenance, regularly checking out the flooring, walls and foundation for cracks. Crack size isn't an issue since all cracks are problematic and can compromise the structural integrity of the parking area. When cracks are noted, managers can personally attend to these by using appropriate crack repair resins like Flexomeric FLEXTUBE-110 Crack Repair Resin. Also, foundation crack repair kits from Flexomeric are also available as a complete solution for foundation and wall cracks.

Protective coat for repaired flooring

Once the cracks have been covered or injected with resin, a recommended next step is to apply a protective coating to prevent future damages or at least slow down future deterioration. Commercial waterproof coating is available, and this is often applied to the concrete deck surface in multiple coats. Expect to pay a premium for protective coat, but this can be helpful in restoring and protecting the concrete flooring against water intrusion and abrasion.

Other protective sealants and solutions are available, and the choice may depend on the budget and condition of the parking structure. Whatever the specific approaches or products use, it’s best to put the condition and structural integrity of the parking structure first on list.
