How do you Stop Water from Coming into your Basement?

This year, the Greater Toronto Area has seen an unusually wet summer. There has been more rain than sunshine, and apart from ruining beach plans, it is highly likely that the ongoing rain can lead to water damage in homes. When houses are built from scratch, they are rarely ever waterproofed and protected from potential water damage. In weather conditions like rain or snow, which are common in Canada, wet basements can cause a variety of problems. For starters, they smell bad. Water damage also ruins the walls and floors of your home and invites sometimes harmful molds inside. If you choose to ignore this problem, the value of your home and its livability can decrease drastically.

What Causes Your Basement to Flood?

When it rains or snows, water is likely to build up in the soil causing the water table to rise. In cases like this, hydrostatic pressure forces the built up water into the foundation of your home. Once the water has penetrated the foundation, it can seep through cracks or openings in the walls or floor of your basement. Waterproofing is required in cases where ground water can build up easily in the soil – which means if you live in the GTA, you should consider waterproofing your basement.

How to Prevent Water from Coming into the Basement

1. Eavestrough Maintenance

Clogged gutters and eavestroughs can be the source of water leakage in your basement since they can cause water to overflow, so consider spending some time cleaning out the gunk in your gutters and eavestroughs. Also, consider installing either plastic or metal gutter downspout extensions. The downspouts that are created with the extensions direct the water away from the house, reducing the amount of water that can flood the basement.

 2. Plug the holes and cracks in the foundation of your home.

Sometimes, water can enter your basement through cracks and holes surrounding plumbing pipes. An easy fix for this is to plug these holes using polyurethane caulking or hydraulic cement. Hydraulic cement is the more popular option because it is easy to work with and it expands while it sets, ensuring a perfect fit in the holes. Although this will not be a permanent fix for the problem, it will help.

3. Waterproof the walls.

The only guaranteed solution is to waterproof the walls with a tried, tested and true rubberized membrane. Loose material is removed from the walls using a wire brush, and the concrete wall is primed. A 4-layer rubberized membrane is then applied directly to the surface of the wall, followed by a final layer of Platon Drainageboard. The goal is to fill every hole or access point to prevent future water leakage.

4. Check the drainage system.

If your basement is flooding, check to see if the water is leaking in the areas where the wall meets the floor. If that is the case, the problem is more than likely caused by hydrostatic pressure. Check the floor drains – these are underground pipes that can be accessed through drain grills or clean out caps (already existing in your basement). If the floor drains are clogged, try a garden hose to clear the mess. If you are still experiencing drainage problems, call a professional.

5. Change the grade

Stop water from entering your basement by adjusting the slope of the surrounding soil. Adjust the soil at a slope of ¼ inches per foot. By doing this, the water drains towards the outside of the house rather than the inside. Simply add soil and use a rake to smoothen it until it is at the required level.

Let Us Help

The above-mentioned steps can cost you unnecessary expenses and take up a lot of your time. Most of the steps may temporarily fix your problem, but for permanent results, you might consider calling a professional. Here is how we will take care of your basement.

Step 1: Our professional team will look thoroughly for any cracks and holes in the basement foundation.

Step 2: Once the cracks are found, we will dig down to the footings and expose the weeping tile system.

Step 3: We will clean the wall using a wire brush and add a layer of primer.

Step 4: After the primer has dried, we will use hydraulic cement to fill in the cracks – its expanding nature will ensure that all the cracks are tightened and sealed.

Step 5: Once the hydraulic cement has set, we add a drying primer. This creates a strong base for the waterproofing process that comes after.

Step 6: Rubberized asphalt membrane is applied to the entire wall. This material ensures that the walls are safe from air, vapor, moisture, water, etc.

Step 7: A layer of fiberglass mesh is applied to allow flexibility.

Step 8: As an extra precaution, another layer of rubberized asphalt membrane is applied to the wall. This makes it near impossible for water to leak through the walls in the future.

We take pride in ensuring that every step of the waterproofing process is completed accurately. You can try to fix the problem on your own, but there can be a reoccurrence of the water leakage problem. To ensure a permanent fix, contact GJ MacRae today!
