The 5 Most Common Waterproofing Problems In Commercial Buildings

It might seem obvious, but it’s not, and there are numerous ways that a multi-story structure is distinct from a home. One of the major differences is waterproofing concerns since there are a lot more dangers for businesses that are utilising the building than for single-business structures.

It is also the responsibility of the proprietors of commercial buildings to ensure that their building is in good condition for tenants and that proper waterproofing is a part of the procedure. Research has revealed that while waterproofing makes up only 1% of the total cost of a building, the damage caused by water leaks is responsible for up to 80 percent of the defects in a building.

The correct waterproofing and making sure that all leaks are stopped the moment they’re discovered ensure the safety of the building as well as prevent the loss of rental income caused by a building’s becoming uninhabitable.

1. Issues arising from the above

Whatever the location of the business premises within the structure, there are always dangers from above.

If it’s on top of the floor, there can be puddles in the roofing. This is especially the case for flat roofs, which hold the water that falls when it rains. The water could be absorbed into the ceiling and cause an issue. If the water remains on the roof, it can cause damage to the structure due to wear and tear.

Additionally, lower floors might be experiencing issues because of poor work on the floor above. Incorrect tiling or plumbing can cause massive problems for the flooring below, which could include cracks, mold, and structural flaws.

2. Incorrect waterproofing

Proper installation is essential in the process of waterproofing. Many leakage issues are the result of inadequate waterproofing, which could cause water damage. If the waterproofing process is completed incorrectly, the building will fall apart much more quickly due to the water buildup. It could also cause damage to the property and, for firms, to the damaged equipment, specifically those located on the lower floors.

3. Balconies

If the structure has exterior areas, it’s a definite requirement that terraces and balconies are waterproofed properly. Whatever the direction of the rain, if the outdoor space is exposed to the elements, it’s likely to be soaked when the weather comes. If it’s not waterproofed properly, water could get into the structure through holes, no matter their size.

4. Windows

Another obvious way for water to enter buildings is through windows. This is not just talking about the ones that aren’t. Windows are very vulnerable to the effects of water, particularly during storms that force rain.

5. Inattention to maintenance is a major cause of failure.

One of the main issues is that we fail to recognize when something is wrong. The smallest of leaks must be taken care of immediately, as they are likely to become much larger ones, which can cause more damage. Also, it is important to check windows, balconies, or any other problems that might pop up and then immediately fix them. The longer these issues go unaddressed, the more damage they are likely to do.

Tips And Tricks

However, hope is not lost. There are a variety of things one can do to reduce the damage caused by water.

1. Make sure you check your roof often.

Although flat roofs are the least vulnerable, regardless of the quality of the roof, they should be checked regularly. It doesn’t matter what material it’s constructed from. Experts recommend that commercial roofing be checked at least every two years. During inspections, the vents and all roof components where water might be able to penetrate the building must be examined. If there are water-based stains, these must be thoroughly examined, as must any cracks, since these can be a sign of areas where water might be accumulating or entering the structure.

2. Check the drainage, plumbing, and irrigation systems regularly.

Leaks of this kind are often difficult to identify, which is why regular checks are vital. The plumbing and draining systems must be inspected for any obstructions or drips. Keep in mind that even if the leak appears to be small, it has a chance to develop into a more serious issue. Therefore, you must address it sooner rather than later. Make sure to consult an expert to resolve the issue. If you’re not a professional plumber, likely, you won’t have the knowledge to fix the problem. It may get worse.

3. Make sure that all seals are maintained.

This is the case for windows as well as door seals and even wall systems. Concrete is porous, and water is a common way to get through. While leaks may appear invisible, however, water is still getting in through the wall. If you discover water damage, you should seek professional help.
