It seems obvious to most, but commercial buildings are different than homes in a variety of ways. Waterproofing methods are one of the biggest differences, as commercial properties are under more threats than single-family structures are. It’s the property owner’s responsibility to ensure that the building is safe for tenants, and proper waterproofing is part of that process. Not only does waterproofing ensure the building’s safety, it prevents the loss of money and productivity that comes when a building becomes uninhabitable. Read on to learn about some of the risks of improper waterproofing.

Problems From Above

No matter which part of a building a business occupies, risks typically come in from above. For instance, if the top floor is in use, puddles may form on the building’s roof. This is particularly true of commercial flat roofs, which tend to accumulate water as it rains. The runoff may seep into the ceiling, causing leaks and other damage. Any water left standing on the roof may damage the building through accelerated wear and tear.

Similarly, lower floors may have problems caused by poor workmanship on higher floors. Defective plumbing and deficient waterproofing may cause serious issues on lower floors, including mold, mildew, cracks, and structural damage. Visit to find out how these problems can be prevented.

Leaks and Equipment Damage

Proper installation methods are crucial where commercial waterproofing is concerned. Many leaks are caused by inadequate waterproofing, and in many cases, the damage isn’t found until it is too late. If waterproofing is done improperly, the building may degrade faster because of built-up moisture. Poor waterproofing may cause direct damage to the building, and in the case of its tenants, damage to equipment.

Outdoor Issues

When commercial buildings have balconies, terraces, and outdoor seating or work areas, it’s crucial that they’re properly waterproofed. No matter the direction from which rain comes, if outdoor areas are exposed to the elements, they’re going to get wet. If these areas are not properly waterproofed, moisture will easily get into the building through the smallest openings.

Window Worries

Windows are another common point of entry for moisture, and in this case, we’re not referring to windows that are left open. Commercial windows are particularly vulnerable to moisture intrusion, especially when rain is driven in by a strong wind.

Foundation Damage

When a commercial building’s basement is not properly waterproofed, its foundation becomes weaker because of constant leaks. As it weakens, the foundation may shift, damaging floors, cracking walls, and resulting in high repair costs.

Mildew and Mold Growth

Damp, inadequately waterproofed environments are conducive to the growth of mildew and mold. When left unchecked, mold and mildew will weaken the building’s foundation and walls. Furthermore, these unsightly growths may cause respiratory issues in those with asthma and allergies.

Flood Exposure

When basements and other areas flood frequently they are more susceptible to severe damage. A commercial waterproofing company can not only identify the source of a leak, but they will also resolve the problem and take steps to prevent future floods.


Business and property owners are often so concerned with the bottom line that they see waterproofing as an unnecessary expense. However, when waterproofing is seen as an investment in the long-term structural integrity of a building, it’s easier to justify the cost. When commercial properties are fully waterproofed, owners will avoid these risks and numerous others.
