The detection and remediation of concrete deterioration
has become an industry unto itself. The source of the problem is
primarily attributable to the brutal environment of South Florida,
particularly along the coast. The air has a high content of
humidity, and also a high content of calcium chloride (salt). Most
hi-rise and mid-rise buildings are constructed of either pre-cast or
poured-in-place concrete. In both cases, concrete is a porous
substance. When the "skin" (paint surface) of the building
is not waterproof, the concrete absorbs the moisture and the salt
from the air. This causes the steel reinforcing bars ("rebar")
to rust. When steel rusts, it expands. This then causes the concrete
to break away from the building, commonly known as "spalling."
By the time significant spalling is detected, there is often
significant damage already done to the reinforcing steel structure
of the building.
The complexities of structural repair and protection of
concrete demand specialized expertise and a full-range of service
capabilities. By applying new technologies to well-established
repair principles, SPECIAL FORCES partners with owners and
engineers to safely deliver cost-effective solutions. We draw from
our many years of experience to perform the optimum repair that best
meets project needs.
In the commercial and public markets, we offer solutions
applicable to the repair of structures including buildings,
high-rise structures, parking structures, plaza decks, and historic
structures. Our experienced, highly skilled technicians repair
spalled concrete surfaces, seal leaking cracks and joints, and apply
coatings and linings.
Concrete repair replaces defective, damaged or deteriorated
concrete, restores structural function, protects itself or
underlying concrete from aggressive environments and restores any
lost performance requirements.
Concrete repair problems are diverse in nature. Each condition
requires a clear understanding of what is expected of the repair
including appearance, protection needs and load carrying
requirements.
An effective repair strategy must draw from a variety of repair
materials, each having an installation technique that best suits
both the material and the strategy. Some examples of the techniques
utilized are: Dry Mix Shotcrete, Dry Packing, Form &
Cast-in-Place, Form & Pump, Full-Depth Repair, Hand Applied
Repair, Overlays, and Wet Mix Shotcrete.
At SPECIAL FORCES we have the expertise to utilize
specialized techniques applicable to repair or restore damaged
concrete.
