Reviving Structures: Concrete Restoration
Statues, monuments, and even skyscrapers are a testament to the multifacetedness and durability of concrete. These structures have stood the test of time and have weathered decades, sometimes centuries of wear and tear. But if concrete is so strong why does it need to be repaired and restored? The truth is that while concrete is inherently strong it is no waterproof. Concrete is a porous material so it has tiny holes/divots in its surface that is permeable by water. Concrete generally has a skeleton made of rebar which if left open to the elements or comes into contact with moisture can rust over time. South Florida’s air has a high concentration of humidity, and also a high level of calcium chloride (aka salty air). Most hi-rise and mid-rise buildings are constructed of either pre-cast or poured-in-place concrete. If the building doesn’t have an impermeable membrane (paint, aluminum, sealant) then over time the elements will start to erode the exposed concrete. When this happens the surrounding concrete can weaken and even crack and fall off. If left on checked this can cause significant structural damage which can be dangerous.
When damage is detected to concrete it needs to be repaired by a process called structural concrete restoration.
What is Structural Concrete Restoration
Structural concrete restoration consists of repairing deteriorated concrete and rusted reinforcing steel to bring the structure back to its original specifications and condition. Structural damage is often found on elevated slabs and catwalks, decks, and parking areas. In Florida, most structural concrete damage is caused by moisture intrusion resulting in the rebar rusting.
When moisture penetrates the concrete, it causes the rebar to rust. When rebar rusts, it can expand to several times its original thickness exerting a force of more than 10,000 psi that causes large cracks and spalling concrete. Seemingly insignificant problems on a building’s surface may be outward indications of much more serious problems beneath that can only be determined by a qualified, experienced structural engineer.
Flat surface concrete roofs in South Florida can be subjected to some of the harshest conditions known to man. Temperatures in the summer months can reach into the mid-high 90s and last for hours. Couple this with being smack in the middle of the hurricane zone and getting more than our fair share of rain, it can wreak havoc on your flat roof.
Basic Repair Methods:
- Removal of existing concrete
- Coating the steel rebar
- Replacing the concrete
- Removal and replacement of expansion joints
- Application of waterproofing membrane
- Mechanically cleaning the steel rebar
- Post-tension cable repair
- Application of corrosion inhibitors
- Routing and sealing of concrete cracks
- Application of decorative coatings
