Waterproofing Works

What is waterproofing?

Waterproofing is the process of making an object or structure waterproof or water-resistant so that it remains relatively unaffected by water or resisting the ingress of water under specified conditions. Such items may be used in wet environments or underwater to specified depths.

Why is Waterproofing Important?

Waterproofing is a fundamental requirement of construction. A building or structure is waterproofed with the use of membranes and coatings to protect the structural integrity.

Sometimes a waterproof membrane is omitted from the design completely, but this is not the leading cause behind waterproofing failure. Poor workmanship is the leading cause of waterproofing failures with 90% of all failures being due to negligent or inadequate workmanship.

Not only does correct waterproofing and ensuring all leaks are plugged the moment they’re spotted ensure building safety, but it also helps prevent the loss of rent caused by a building becoming uninhabitable.

Common Source Of Waterproofing Problems

Waterproofing failure has different potential causes, but poor workmanship and the use of a membrane that is not fit for the purpose or is not part of an entire system are the leading causes.

Listed below are the 5 most common

1. Issues from above

If it is on the top floor, puddles can form on the roof. This is especially true of flat roofs, which collect water when it rains. This water can potentially seep into the ceiling space causing a leak. Any water that remains standing on the roof has the ability to damage the structure through wear and tear.

2. Incorrect waterproofing

Correct application is key when it comes to waterproofing. Many leakage problems are caused by poor waterproofing, which can result in moisture. If the waterproofing is done incorrectly, the building can degrade much quicker due to the moisture build up. 

3. Balconies

Regardless of the direction of rain, if the outside area is open to the elements, it’s going to get wet when the weather hits. If not waterproofed correctly, water can get straight into the building through the openings, regardless of how small the opening is.

4. Windows

The other most obvious place for water to get into buildings is through the windows. And we’re not talking about open ones. Windows are extremely vulnerable to water, especially from rain driven by strong winds.

5. Ignoring the need for maintenance

Perhaps one of the biggest problems though is ignoring the situation when something goes wrong. Even the smallest leaks should be dealt with immediately as they have the potential to grow too much bigger ones that will cause much more damage. This also means checking balconies, windows, cracks and any other issues that may crop up, and immediately dealing with them. The longer these issues are left, the more damage they’re going to do.

So what Can you do?

Not all hope is lost though. There are many things one can do to minimize water damage.

1. Inspect your roof regularly

Even though flat roofs are the most vulnerable, regardless of the gradient the roof should be inspected on a regular basis. It also doesn’t matter what material it’s made from. Experts recommend that a commercial roof should be inspected at least twice a year. During the inspection vents, drains and any rooftop elements where water may be able to enter the building should be checked. If there are any water stains, these should be thoroughly inspected, as should any cracks, as these are a good indication of where water may be pooling or even getting into the building.

2. Regularly check the drains, plumbing, and irrigation

These types of leaks can sometimes be hard to spot so regular inspections are an absolute necessity. Draining systems and plumbing should be checked for any blockages or drips. Remember, even if a leak seems small, it has the potential to grow to a much bigger problem to deal with it sooner rather than later. And always consult an expert to fix the problem. Unless you’re a plumber yourself, it’s unlikely that you’ll have the expertise to fix the issue. In fact, it may get worse.

3. Ensure all seals are maintained

This goes for all window seals, door seals, and even wall systems. Concrete is a porous substance so water commonly gets through. Remember, while leaks may sometimes not be visible, moisture is still getting through the wall. If water damage is found, again, get the experts.

Solution by PU Grouting Injection

Hydrafoam PU is a hydrophobic polyurethane grout designed to stop water leaks. It is typically injected into cracks in concrete, honeycombed concrete, soils, pipes, pipe intrusions and other voids by use of a high pressure pump. When the liquid polyurethane meets water or moisture it reacts with it and then expands, creating a dense, closed cell foam through which water will not pass. In an unconfined environment the expansion rate of the material is 20 times its own volume.

Hydrafoam PU is typically used to stop water leaks coming through cracked or honey-combed concrete voids between wall and floor, wall and ceiling, expansion joints, cold joints and pipe intrusions. It is used to repair concrete walls, ceilings and floors that are leaking; in tunnels, including limestone, manholes, sewer lines and in concrete dams.
