Improve the Durability of Your Parking Garage.
Buildings are investments in the future. Building a concrete parking garage takes much care and consideration so that it will have a long life. Here are the tips for designing your parking garage so that it will stand the test of time.
Because of the importance of details in designing and constructing parking garages, you should choose a designer who will focus his attention to detail. If you want your concrete parking garage to have a long life span then you need a carefully detailed design structure that addresses serviceability concerns. Engaging your design team in the construction is important and you should also include the provisions of the international building code for structural tests and special inspections to ensure the evaluation of the work for compliance with the design intent.
If your concrete garage is precast, there will sometimes be joints and exposed steel connections. In order for the precast concrete garage not to deteriorate quickly you need to make sure that they are detailed and constructed properly. All exposed steel connections and embedded plates should be hot-dipped galvanized, at a minimum.
What I Can Teach You About Garages
If you have a cast-in-place post tensioned concrete structure, make use of encapsulated tendons and a concrete mix design which is proportioned for durability.
A Quick Overlook of Construction – Your Cheatsheet
If you increase the protective concrete cover over the embedded reinforcing steel, then you also achieve improved durability. 2 inches of thickness is recommended for surfaces which are exposed to de-icing chemicals and other harsh elements. black mild steel reinforcement with increased cover is preferred over epoxy coated reinforcement with less cover.
IF there are cost in place concrete portions of a structure, electrical conduits to be embedded in it is not allowed. Severe damage can be caused to your parking garages if you embed electrical conduits because it can corrode and expand, and cause delamination and spalling.
The minimum floor slope for positive drainage should be observed to effectively increase a parking structure’s life expectancy. This reduces the potential leaching of contaminated water into the concrete and causing corrosion of mild reinforcing steel, prestressed strands, or post tensioned tendons.
Regular maintenance and cleaning of the parking structure should be done. Extending the life of your parking garage needs regular maintenance like removing harmful elements that are found in the garage even before they can cause damage, retouching galvanized coatings on exposed steel connections, and repairing failed joint seals and sealants.
The garage design that does not need a surface applied traffic coating is the design that will ensure durability. For those garage design that do not adhere to the best practices, the option of traffic coating can extend that life of the garage. Reducing energy can be done by using traffic coating.
