If you’re a property owner, chances are you’ve experienced the headaches and frustrations of leaky structures. Dealing with water damage in your underground structures can be one of the most difficult challenges you will face with your property. Luckily, there are several methods of waterproofing out there. We’re taking a close look at two of the most popular types – excavation and hydraulic injection waterproofing – to help you the next time those pesky leaks start to show up.


Excavation Waterproofing


In the case of excavation waterproofing, a drain is installed underground. This requires digging on the exterior of the house, to place a protective membrane and keep water from getting into underground spaces. Although it’s regarded as a very effective solution, it’s also known to have some major drawbacks.


It’s Costly

Proper placement of a waterproofing system via excavation is a big project, involving not only the prep work but also the installation, and then filling back in what has been taken out. Because so much work is required in order to complete an excavation properly, these projects can run you up to $80,000.


It Can Be Time Consuming

Not only does it take time to properly dig a trench around your home, place the membrane, and refill what has been taken away, you also must wait until the dry season for this process to begin, delaying the start of the project.


It’s Disruptive


Because excavation requires digging a large trench to place the waterproofing system, your entire home will be disrupted. Often, it requires removing plants, shrubs, or even entire patios and walkways. In some cases, it can even be dangerous, impacting a whole section of your home.


Hydraulic Injections

The best way to quickly and effectively stop leaks is through a process called hydraulic injection waterproofing. This is when a polyurethane solution is inserted into any cracks in basement walls, creating a complete seal to prevent any water from getting through. Because of it’s simple nature, there are a few major benefits to this type of waterproofing.


Your Property Can Remain Open

Because there is no need for any excavation, your property won’t be affected by the injections. The waterproofing specialist will need access to your basement, but the process takes almost no time to complete.


It’s Quick and Easy

The only preparation required for the injections is ensuring the crack or seam is clean and flushed out with water. After that, the injections are inserted and dry very quickly, immediately beginning to block out any leaks within just a few minutes.


It’s Cost-Effective

Unlike excavation, hydraulic injections require little equipment, meaning there aren’t many extra costs. The simple procedure is only about ⅓ of the cost of a full excavation process.
