Sometimes, concrete is just beyond repair or repatching that it is just a
waste of time and money to try and fix it. Trying to repair the broken concrete
will only make the entire area look dirty and indicate shoddy workmanship. At
this point, concrete removal is necessary and there are several ways in which
this can be done.
When to Remove Concrete
Once deep cracks begin to appear in existing concrete, removing the concrete may
be needed. Concrete removal is also a good idea if concrete slabs have begun to
sink in over a period of time. In very cold climate conditions, it is not
uncommon for frost to cause concrete slabs to heave. If this is the case, an
addition could be added to the construction of your project after a few years.
Concrete that is causing a problem in this type of project may have to be
removed. Faulty concrete could also be the source of your problem. Road repairs
and street widening are also common causes of concrete needing to be removed.
Techniques for Removing Concrete
There are several ways in which concrete can be demolished or removed, including
the use of pneumatic and hydraulic breakers, which work by breaking down the
cement. This is an effective from of concrete removal for pavements, foundations
and the decks of bridges. Dismantling involves cutting through the concrete
structures and then dismantling them. Water jetting is used to minimize the dust
particles that arise and to eliminate fire hazards. For larger constructions,
explosives may be used to remove old concrete. This technique is by far the most
dangerous and certain safety risks need to be addressed. Individuals are not
equipped to do this; this form or concrete removal should only be handled by a
skilled professional -- either a removal contractor or by concrete demolition.
Safety Risks and Measures for Concrete Removal
To remove concrete, safety gear must be worn at all times. Shovels are one of
the most common construction tools used for removing concrete. Back injuries are
common if shovels are not used properly. Those removing concrete should never
wear lose clothing; safety goggle and face masks are needed to prevent
inhalation of dust and other small particles. Heavy work boots and shoes are
also a requirement for contractors and workers. In fact, protective gear should
be worn by anyone supervising the construction site, including homeowners.
