Knowing about Concrete Restoration and Spray Foam Insulation

Concrete plays a huge role in the look, structure and sustainability of commercial and residential buildings, such that when concrete is damaged, its ability to support the building is weakened, as well as the insulation properties of the building.

The process of concrete restoration in residential and commercial buildings is applied to realize its main objective, which is to repair old and damaged concrete in buildings and to restore the building’s appearance to its original form.

Because concrete restoration is less expensive than constructing a new building, building owners would prefer to apply concrete restoration to repair cracks that are the cause of structural problems and be assured that the process can give back the appearance of a brand new look on a once damaged building.
Short Course on Experts – What You Should Know

Determining first the cause of the concrete defects before repairing it should be the first step to be observed, because if the cause is not determined, then the same damage can be repeated even if the repair work has been done. The concrete restoration process must be flexible to include the effect of the cause of concrete defects, if the cause of the damage is repetitive in nature.
Finding Parallels Between Installations and Life

Since a thorough evaluation has been made regarding the extent of the damage to the concrete, it is easier then to make a decision on whether the damage can be repaired or the structural parts have to be replaced and, at the same time, it helps to take precautionary measures to stop the damage in the future.

The most common technique in determining the extent of damage is by sounding the damaged and surrounding undamaged concrete with a hammer by an experienced personnel, such that in sounding suspected delaminated or disbanded concrete, they may not always sound hollow, so it’s important to place a hand close to the location of the hammer blows or by closely observing sand particles on the surface close to the hammer blows; if the hand feels vibration in the concrete or the sand particles are seen to bounce even with a slight hammer blow, then the concrete is delaminated.

The process of concrete restoration should be carried out immediately on the concrete if the damage affects the safety and serviceability of the structure or if the damage has reached a stage where the structure becomes unserviceable, since not all damaged concrete requires immediate repair and most concrete damage progresses slowly.

Well-insulated building is warm during the winter and cool during the summer, this is because the insulating material prevents the flow of air in the building to escape through the walls or ceiling. Air is free to pass in and out of the building walls, if the building has damaged concrete, that’s why concrete restoration is applied to repair the cracks in the concrete.

If concrete restoration may not be possible, using spray polyurethane foam as an alternative insulation material can help seal the air on walls, roofs, and all contoured surfaces, and reduces unwanted air infiltration through cracks, seams, and joints, as well as resist heat transfer extremely well.
