Types of Concrete Restoration and Available Concrete Repair Options

Concrete Restoration can include superficial cleaning or deep repair of structural concrete. The type of damage sustained by your material will delineate which kind of work will be required to restore the concrete to its original condition.

Types of Concrete Restoration

  • Outer building repairs involve structural stabilization and replacement of damaged components. Due to water infiltration or damage from the environment, we must remove the facing surfaces and decking materials from the structure, stabilize the steel framework tying the structure to the building, and replacing the surfaces with new material.
  • Shotcrete can be used for concrete repair. Shotcrete is concrete combined with compressed air, pumped through a hose at high pressure, and applied to the final surface. The force of the air consolidates the mixture on the surface, causing it to harden.
  • Polymer-modified concrete mortar can repair concrete with the addition of plasticizers to traditional mortar. The additives increase mechanical performance of the mortars and improve adhesion, extend allowable working times and improve workability in hot weather. These mortars offer improved chemical resistance, higher chemical flow, increased flexibility and increased compressive and tensile strength.
  • Concrete Demolition, the removal of damaged or undesired concrete is required when the concrete is unsalvageable and done with a jackhammer, or other pneumatic equipment.
  • Parking structure repairs involve repairs to both the deck surface and to overhead concrete structures that are damaged. Parking lot areas are typically affected by by water infiltration, structural damage or exposure to melting agents.
  • Traffic coatings in highly used areas protect concrete surfaces from damage caused by vehicles, machinery or pedestrian traffic. Concrete coatings are made from an epoxy base and seal moisture and damaging materials from leaking in.
  • Concrete structures are reinforced by rebar or structural steel, but if the concrete skin has been damaged we may need to to replace the steel substructure. If the building has been built with minimal steel in the structure, an anchoring system to stabilize the building will need to be built.
  • Cementitious coatings are comprised of Portland cement and a vermiculite or perlite premix. This results in a protective coating that is fire resistant and is applied to steel or concrete surfaces while a structure is under construction.
  • Facade repairs: If there is damaged, spalled or degrading concrete from the surfaces of a structure, this material will need to be replaced. The process is to stabilize the repair site, fill g any voids or cracks with new material, and formulate the filling to match the color and texture of the existing concrete material. Facade repairs demand the creation of customized forms to allow for replication of details that were cast in place.
  • Concrete sealing closes the porous surface of concrete and makes it impervious to moisture and damaging substances. Sealing concrete will protect it from gasoline, oils, excessive water and caustic salts.

Finding an experienced concrete restoration firm that   provides  a solid estimate for the repair work will ensure these changes happen smoothly. We have a complete list of  qualified references and can provide a yearly maintenance plan for post restoration upkeep.
