Importance of Waterproofing for Ajax Properties

Why Get Basement Waterproofing Services Ajax?

Basement is one of the areas in a house that is most susceptible to water intrusion. Changes in temperature, rain, melting snow and multiple other factors can lead to hydrostatic pressure that can cause groundwater to enter the basement.


This may lead to a variety of leaks:

  • Basement Floods – we often help people who experience basement floods of various intensity – from a fem inches of water to full scale water intrusion.

  • Damp or Wet Basement Floors – in some cases, instead of a flood you may see damp or wet basement walls and floors, often close by the wall of floor cracks, joints etc.

  • Water Seepage – is another common problem that leads to water coming up from the basement floor, or entering the basement where wall and floors meet.


In addition, wet basement problems can lead to a variety of problems:

  • Mold & Mildew – often grow in wet basement environments and can be harmful to your health.

  • Foundation Damage – if you don’t get basement wall and floor crack repair, this can lead to foundation damage and more expensive foundation repairs.

  • Construction Materials Damage – leaky basement can damage wall and floor coverings and result in more than just leak repair.


Whether you need basement leak detection or basement leak repairs, repairing foundation or a wall crack, or even basement underpinning, team at Aquamaster in here to help. Get one of our experts on the phone today!

Services Under Basement Waterproofing

Basement Waterproofing Ajax that Fits Your Needs


No two basement waterproofing projects are the same and neither is the scope of work. In some cases, we need to repair foundation cracks, on others – deliver same-day emergency waterproofing. Often our interior & exterior waterproofing services are combined with basement underpinning Ajax and more. Here is a couple of services that are often a part of waterproofing in Ajax.

Considered to be a long-lasting, permanent solution. External waterproofing often includes excavation, cleaning the exterior walls, and repairing basement wall cracks. Multiple levels of the waterproofing membrane are then applied to the walls. Weeping tiles is installed and the are is backfilled with gravel & soil.

A sump pump is a device used to remove water that has accumulated in a sump pit, which is a low-lying area typically found in basements or crawl spaces of homes. The purpose of a sump pump is to prevent flooding by efficiently pumping out water that collects in the sump pit.

When water enters the sump pit, either through natural groundwater or as a result of heavy rain, the sump pump automatically activates to pump the water out and away from the building's foundation.

Basement plumbing rough-ins & basement bathroom rough-ins are some of the most popular services along with new construction waterproofing. They involve our team of basement waterproofing contractors installing pipes and vents for the plumbing system in new construction projects. This service involves routing pipes through wall cavities, running vent stacks to the roof, laying underground pipes, and installing fixtures and end elements etc.

If you are experiencing wet basement problems or see foundation leaks on your walls, this could be a sign that you need a foundation leak repair. The first step is often foundation leak detection. Our teams are trained to deliver quality foundation leak detection & repair services and have all the necessary equipment with them. Let us find the leak in your basement & do the foundation crack repair to address it!

This waterproofing solution requires maintenance to prevent basement floods. Interior waterproofing applies membranes inside the basement. These membranes collect the water that enters the basement and direct it to the sump pump, which activates once water raches a certain level. This solution is less expensive but requires maintenance and doesn't prevent water from entering the basement. 

Crawlspaces can have water damage problems similar to basements. In addition, in crawlspaces floors are often unfinished which makes it even easier for water to make it through. This can spoil air quality, lead to mold growth and foundation damage. A lot of the air in your home comes from the crawlspace so it's important to make sure it's a healthy & dry environment. Encapsulation, installing dehumidifiers and other services will help keep your basement dry.

Basement walkout construction refers to the process of creating an exterior access point from a basement or lower level of a building to the outside. It involves creating an opening in the foundation wall and constructing a walkout or stairwell that allows people to enter or exit the basement directly from the ground level. Basement walkouts can provide numerous benefits, including increased natural light, improved ventilation, additional living space, and enhanced accessibility to the basement level.

If not repaired on time foundation cracks can get worse over time and can cause basement leaks, structural damage as well as basement floods and more.

Basement underpinning is a construction technique used to strengthen and stabilize an existing foundation by increasing its depth (basement floor lowering). It involves excavating the soil beneath the foundation and then reinforcing it with additional concrete or steel supports.

Underpinning is typically done in situations where the existing foundation is inadequate to support the load of the structure above or when there is a need to increase the basement's headroom. It can also be done to repair a damaged or compromised foundation.

Weeping tile, also known as a French drain or perimeter drain, is a type of drainage system commonly used in residential and commercial construction. It is designed to collect and redirect water away from foundations, basements, or other areas where water accumulation may be a problem. Weeping tile consists of a perforated pipe, typically made of PVC or a similar material, that is placed in a trench around the perimeter of a building's foundation or in areas prone to water infiltration. The pipe is laid with the perforations facing downward to allow water to enter the pipe.

The purpose of weeping tile is to collect water that seeps into the ground and direct it away from the foundation

Basement Waterproofing Reviews

What Our Clients Say?


Stephanie G.

Residential Client

I used Aquamaster for two separate home waterproofing projects and I was extremely satasified with their work and price. Their team are highly skilled, thorough and were able to complete the 10.5 hour job in one day. They were even kind enough to seal my window frame after I noticed a minor leak. I would highly recommend Aquamaster for all your waterproofing and plumbing needs.

The Aquamaster team is absolutely fantastic! They went above and beyond to diagnose and correct the problem that I had with my basement plumbing caused by old pipes and persistent tree roots. I used them once in 2012 and in 2020. I cannot say enough good things about this team - Highly recommend.
