FAQs

Q?

What causes Concrete Deterioration?

A.

The most common and damaging force to concrete deterioration is moisture. If you have cracked or damaged concrete, it is much easier for water to seep through and causes rebar to rust or stucco to delaminate, causing further damage to the structure of the building.CraneCrest3-24-16-19

Q?

What is concrete repair/ restoration?

A.

It is the practice of stopping the cause of damage to the structure of the building. In addition, a sealant is applied to deter future damage. If the damage is deep, the concrete will be removed and new concrete is poured and applying design mixes that contain corrosion inhibitors to ensure future protection.

Q?

How come we do not find this rapid corrosion problem up north?

A.

Here in South Florida we have an extremely high levels of salt in the air, combined with humidity.  These conditions are which cause the corrosion problems that occur. The Atmospheric Exposure Site (Kennedy Space Center, FL) was established in the 1960s and has been cited as the most corrosive atmospheric corrosion test site in the United States. It is located at latitude 28.59406°N, longitude 80.58283°W, and approximately 100 feet from the high tide line. Over the years thousands of coated test panels, stress corrosion cracking specimens, and commercially produced components have been evaluated in the high salt, high humidity, high UV Florida seacoast environment.

Q?

How do we know when our building needs work?

A.

The best way is to have regular inspection performed by a structural engineer that is experienced in the field. Common signs that your building may be in need of restoration are: rebar exposed or you can see the concrete splitting, concrete that is fracturing or buckling or pushing outwards; peeling paint; lifting tiles especially on balconies or catwalks; standing water on a deck or balcony; or leaks - these are some but not all signs that your building is in need of repairs.

Q?

What do I do to take the first step towards my restoration project?

A.

Call Carousel, we will be happy to take a look at your project and give you a list of structural engineers if needed.

Q?

What if the building is not repaired?

A.

Your building will only continue to deteriorate. The problem will continue at an increased rate and the cost of the repairs will escalate. Eventually, if the repairs are not done your building could be condemned.

Q?

Can my maintenance guy fix it?

A.

No. Concrete Restoration is a very specialized field, it is necessary to have a contractor that is well educated in this area of restoration and methods of repairs. For instance, the general contractor must have the proper state licenses, but in addition, both  your engineer and contractor should have years' experience in the restoration field. Many repairs involve substantial hoisting of equipment which must be done in compliance with laws and OSHA standards. Also, the rebar needs to be handled with care, as it is very important to the strength of the building. There are many different types of waterproofing systems and someone with knowledge and years of experience will be able to provide you with insight to the proper ones to use.

Q?

Does painting over the exposed rebar help?

A.

No, it will not fix the problem. It will only make the building look good but it will not protect the integrity of the building nor will it fix the problem. Painting will not waterproof to the fullest extent necessary to protect your building.

Q?

Are the repairs just about replacing the concrete?

A.

Concrete restoration involves much more than just replacing the concrete. You need to make sure the problem that caused the issue in the first place is addressed. The proper corrosion inhibitors are in place, the proper painting and waterproofing systems will be used. This all needs to be done in accordance with building codes and the work must be done following OSHA standards.

After the restoration is repaired your building will need exterior painting.

After the restoration is complete your building will most likely need exterior painting to complete the new facade of your building.

Q?

Why is it important to have a reputable contractor?

A.

People that are reputable will be able to get the proper an adequate bonding. If a contractor isn’t reputable they could put your building in physical and legal danger.

Q?

What are the advantages of using a locally owned company like Carousel Development & Restoration, Inc.?

A.

We have been working in this field and in South Florida since 1979. We know how to do the work that is best suited for the geographical demands of this area. You get personal attention and direct contact from the owners of the company. Our key employees have over 200 years' experience in the field.

Helpful Terms – Terminology used in the restoration business.

A.

  • SPALL- Cracking or flaking of concrete slabs due to expansion of corroded rebar.
  • REBAR- Steele bar inside of concrete slabs to provide added strength.
  • CURE- The process of hydration that causes concrete to harden and gain strength.
  • HYDRATE- Chemical reaction between Portland cement and water that strengthen concrete.
  • POST TENSION CABLE- A steel cable sleeved in plastic, poured into concrete slabs and tightened after curing. To provide protection from deflection or bending and allows for longer spans between columns.
  • EXPANSION JOINT- Intentional void left in a concrete slab to allow for expansion of the slab without cracking.
  • WATER PROOFING MEMBRANE- Layer of material installed between the concrete slab and the slab finish to protect the concrete from water damage.
  • CANT BEAD- An bead of caulk laid at a 45 degree angle in a corner.
  • TEMPORARY WALL- A wall constructed to protect the inside of the homeowner's unit when the sliding glass doors need to be removed for concrete repairs.
  • MCI- (Migrating Corrosion Inhibitor)- Chemical sprayed on concrete slabs that penetrate the concrete and protect rebar from corrosion.
  • SURFACE REMOVAL- Removing the finish of a concrete slab. ( Tile, spray deck, waterproofing, membrane, etc)

GETTING STARTED WITH YOUR CONTRACTOR AND WHAT TO KNOW

-A structural engineer should be hired to evaluate your needs and guide you through the bidding process.

-Make sure that any contractor hired is experienced, licenses, bonded and insured.

- Generally speaking, the work performed should come with a 5-year warranty.

- Establish a funding plan between the Condominium Association and the Unit owners.

- Weekly Project meetings with your Engineer, Contractor and Association Representative will keep everyone informed as to the progress of the work.
