As we mentioned in a past column, summer is the most suitable season for mold…
Maintain the integrity of your concrete balconies
As all of us can see by surveying the countless streets that crisscross the province, concrete balconies are present in Quebec because they offer a sustainable surface. However, some products such as de-icing salts and tools such as metal shovels can contribute to their deterioration. It is not uncommon during our inspections to find rusty and friable reinforcements or pieces of concretes detached from the structure, which greatly compromises their integrity.
To avoid premature wear of these structures, as our inspectors find too often, it is important to take certain basic precautions.
In addition to being detrimental to the environment, de-icing salts with sodium chloride or calcium can rust the steel frames inside the structures. The reinforcement is what confers strength to the concrete of the balcony and prevents it from collapsing prematurely. Think of a viaduct; the integrity of the structure is greatly compromised as soon as the frame is damaged.
Considering that the use of these de-icing salts exponentially increases the cycle of freezing and thawing, which causes a premature erosion, it is not surprising that it should not be used on all concrete surfaces. Sands or fine gravels would be good substitutes because they will prevent users from slipping while maintaining the integrity of the reinforcement of the concrete. Once the spring comes, a simple broom will take care of the the accumulated surplus without any damage to the structure.
Another important aspect to keep in mind in the winter regarding the concrete steps is the frost heaving. Usually, home builders deliver homes to their new occupants with a rough terrain layout (no lawn or landscape work). When it comes time to finalize this aspect of your home, our experts advise you not to fill the gap between the ground and the bottom of the last step of the balcony because this spacing fulfills a precise role; preventing the frost from raising the soil and damaging the concrete staircase.
