Basement Waterproofing Systems


There are several basement waterproofing system options offered for waterproofing for your home’s foundations. These solutions are can be categorized into three main systems of waterproofing. Traditional systems are still available today, as well as the up-to-date basement waterproofing systems that offer protection that is more superior. The systems are tanking as well as interior and exterior water proofing systems.


This is a method that is popularly employed. Instead of blocking the water from flowing inside your walls as tanking does, the water is allowed to flow into your house before being channeled away. Tanking brings out a modern solution through waterproof membranes. They are used to waterproof the interior walls while acting as an ‘umbrella’ of some sort. The membrane catches any water that gets into your basement thus letting it flow into the drainage. Weeping tiles and pipes are used in the drainage systems to direct water away from your home. Sump pumps, which are great water control systems that force water away from your house, can be fixed in some cases. Interior basement waterproofing systems are then hidden beneath your inner basement floor. They are very effective, useful and cost effective remedies for basement waterproofing, and deliver added advantages over the outdated tanking method thus draining instead of containing water.


These systems have been in function for quite a long time, and are a reserved method that has with time evolved to become more efficient and substantial than before. Exterior basement waterproofing systems are applied during construction, since this prevents the need for digging. However, when applied as a post-construction system, it is very effective and worth the financial implications.

The outside of your building is dug down to the footings of the foundations. Very good quality waterproofing materials are applied to the walls outside to inhibit water from getting into your home. The blocked water that collects is fed into drains, which were fixed to direct water away from the home. These are normally French drains which are excellent basement waterproofing system options.

Tanking systems

Tanking has always been a traditional approach when it comes to basement waterproofing system options. It involves work on the foundations of your basement’s interior. This is a system whereby all the inside walls are coated with such things as a thick layer of hydraulic cement, paints, resins or sealants for waterproofing purposes.

The result is a basement that looks like a protected tank in a way that water has no means of getting into the room’s interior. Many professionals still employ this technique, and amateurs can also be able to use it. Despite being a simple technique to implement, tanking has its shortcomings.

Firstly, the tanking systems can develop cracks due to underground vibrations or as the house settles. Another key problem is the method does not drain the water, which may result in pressure against the walls.

We do not use the tanking method at Aquatech Waterproofing. However, if we tank your walls, then we use delta membranes and cavity walls to form a barrier that lets water drain away safely from your house.

Which waterproofing system is best for me?

Though tanking has remained to be a popular option, we consider it an outdated system in the face of the current interior and exterior systems available. Exterior waterproofing systems are considered the most complete, since they inhibit water from entering your house. It is relatively costly, due to the digging required. It is highly recommended to those willing to spend. Interior waterproofing system ensures prompt relief from a leak issue and is simpler to implement. Water may get into your house, but is unnoticeably drained away and does not bring harm. Interior systems are less costly.

Basement Waterproofing System to Keep Water Out of Your Basement During Rain and Snow Melt Season

Basement waterproofing system are needed for most homeowners in Toronto. This is because the transition from winter to spring weather can cause problems for homeowners when it comes to basement water intrusion.

Check Downspouts and Sump Pump Drainage Lines Around Your Home

It’s common for snow to pile on top of downspouts and prevent water from escaping. This can be an even larger issue when we’ve got snow melt and rain around the same time. Removing snow from around your downspouts will ensure your gutters are able to work as they normally do to capture water and redirect it away from your home and foundation.

Much like downspouts, above-ground basement waterproofing systems like sump pump drainage lines can be a problem in the winter. If snow is not removed from around the discharge lines, the drainage pipe can freeze, leaving no way for the water to leave the discharge line. This means water that enters your sump pump in your basement has no way to escape. This will make your sump pump run constantly and it will eventually burn up.

Knowing this, you may ask “How do I know if my sump pump discharge line is frozen?” Your sump pump will be running non-stop and it will actually begin to feel warm to the touch. If your sump pump or the water in your sump pump feels warm, you likely have an issue. You can also look at your outside drainage or discharge line and see if water is leaving the PVC pipe, or look inside the pipe to see if you have ice buildup. If your discharge line is frozen, you will likely end up with water in your basement.

Create Paths for Water to Drain Away From Your Foundation

Create paths for water to drain away from your foundation. If the soil around your basement is saturated with water, hydrostatic pressure will build. Water can then find its way in through the path of least resistance. These paths of resistance can include porous concrete foundation walls, form ties on poured foundation walls, cracks in foundation walls, and the cold joint where the foundation wall and footing meet.

Move Snow Away From Your Siding

If snow is built up against your siding, shovel it away. There is a wood sill plate that sits on top of your foundation wall. The melting snow can seep underneath your siding and come in between your sill plate and foundation wall.

Prevent Future Basement Water Problems

To ensure your basement stays dry regardless of weather conditions is a properly working drainage and sump pump system. The keyword here is properly working. Not all basement waterproofing systems, including the one that may have been installed when your home was built, are built to operate effectively for years to come. Additionally, because of the mechanical nature of a sump pump, even the best basement waterproofing system requires regular maintenance.

With a properly working basement waterproofing system, water is collected, directed to a sump pump, and pumped out of the home.
