What you Get with Basement Waterproofing?

What are the Benefits of Basement Waterproofing in Hamilton?

Basement waterproofing will help protect your commercial or residential property from water damage. The extent of the benefits you get will depend on the specific basement waterproofing services that are included in your project.


Here is a couple of basement waterproofing benefits:


  • Your Foundation will Live Longer – groundwater causes water damage to your foundation. Exterior basement waterproofing will help seal your foundation from the ground water. This means that your foundation is likely to live longer.

  • Prevents Basement Waterer Leaks – depending on the specific basement waterproofing service you get, the number of water leaks in your basement will decrease or basement water leaks will be gone completely.

  • Protect Construction Materials – water that makes it through your basement walls & floors can damage floor coverings, drywalls, paint and other construction materials it gets in touch with. Basement waterproofing will help prevent water damage.

  • Helps Prevent Basement Floods – basement leaks tend to get worse over time. If not basement leak repairs are not done properly or not done on time, at some point you may get a bigger problem – a basement flood, that are harder to stop and repair.

What Basement Waterproofing Approach is Right for You?

What is the Difference Between Exterior & Interior Basement Waterproofing?

Interior basement waterproofing and exterior basement waterproofing are two different methods of preventing water damage in your basement.

Interior basement waterproofing is rather a way to manage basement water, as it doesn't prevent water from entering your basement. Interior basement waterproofing typically involves installation of an interior drainage system, which collects water that enters through the walls and directs it to a sump pump, which then pumps the water out of the basement. 

Exterior basement waterproofing involves excavating the soil around the foundation of the property, repairing existing foundation cracks, and applying a waterproof coating or membrane to the exterior walls. Next steps involve weeping tile installation and more.

Exterior basement waterproofing is considered to be more effective. But it can also be more expensive and time-consuming than interior basement waterproofing, as it requires excavation and can be more complex to install. 

The best approach to basement waterproofing for your property will depend on the extent of the water damage, the amount of groundwater in your area, your budget, and your objectives. Get one of our basement waterproofing contractors on the phone today!

The scope of a perfect basement waterproofing project depends on your specific situation, budget, and objectives. Here are a couple of services that can be included in your waterproofing project in Hamilton.

Exterior basement waterproofing is a method of preventing water from seeping into a basement by applying a waterproof coating or membrane to the exterior walls of the foundation. This method involves excavating the soil around the foundation of the home to expose the exterior walls, which are then cleaned and prepared for the application of the waterproofing material.

The waterproofing material can be a liquid membrane or a sheet membrane, and it is applied to the exterior walls in multiple layers to ensure maximum protection against water intrusion. Once the waterproofing material is applied, the excavated soil is backfilled and compacted, and the surface is restored to its original condition.

A sump pump is a device that is used to remove water that has accumulated in a sump pit or basin. Sump pumps are typically installed in the basement or crawl space of a home, where water can collect due to natural groundwater or from flooding. When water collects in the sump pit, the pump is activated and begins to pump the water out of the pit and away from the foundation of the home. It is extremely important to ensure proper sump pump maintenance and to do sump pump repair or replacement as soon as your sump pump breaks. A broken sump pump may lead to a basement flood.

During basement plumbing rough-ins, the pipes are typically installed in the walls and floor of the basement. This includes pipes for hot and cold water supply, as well as drain pipes for wastewater and sewage etc. Vent pipes are also installed to ensure that the plumbing system operates correctly and to prevent sewer gas from entering the home.

The purpose of basement plumbing rough-ins is to prepare the basement for future plumbing fixtures such as sinks, toilets, and showers.

Basement Leak Detection & Basement Leak Repair Hamilton

Basement leak detection and repair is the process of identifying and fixing any leaks or water infiltration issues in a basement. Basements are prone to water damage and leaks due to their location below ground level, and these issues can cause serious damage to the structure of the building and the contents of the basement. Basement leak detection will help identify the specific source of the water leak. Our experts will then shift to foundation leak repair and will recommend the right solution to the basement water leak in your property.

Interior basement waterproofing is a method of preventing water from seeping into a basement by installing a drainage system on the interior of the basement walls. This method involves the installation of a perimeter drain system, which is typically a PVC pipe that is installed along the base of the interior basement walls.

The perimeter drain system collects water that enters the basement through the walls or floor and directs it to a sump pump, which then pumps the water out of the basement and away from the foundation of the home.

Crawlspace Encapsulation

Crawlspace encapsulation is the process of sealing the crawl space of a building with a vapor barrier to prevent moisture and other environmental elements from entering. The encapsulation process involves sealing the walls and floors of the crawl space with a heavy-duty plastic sheet or other barrier material, along with sealing any openings, such as vents or pipes. Crawlspace encapsulation has several benefits, including improved indoor air quality, increased energy efficiency, and protection against structural damage. By sealing and insulating the crawlspace, homeowners can prevent moisture and pests from entering the home and can reduce the risk of costly repairs due to water damage or mold growth.

Foundation repair refers to the process of repairing and restoring the structural integrity of a building's foundation. This can involve repairing cracks or other damage to the foundation walls or floor, stabilizing soil that has settled or shifted, and reinforcing the foundation to prevent further damage or settling.

Foundation repair is important because foundation problems can lead to a wide range of issues throughout a building, including uneven floors, cracks in walls and ceilings, doors and windows that don't close properly, and water damage. If left unchecked, foundation problems can also compromise the safety and stability of a building.

The exact methods used for a foundation repair will depend on the specific issues affecting the foundation. Make sure to consult a specialist if you see signs of foundation damage.

Foundation crack repair refers to the process of fixing cracks that have developed in the foundation walls or floor of a building. These cracks can occur due to a variety of reasons, including soil settlement, water damage, poor construction, or natural wear and tear. The repair process typically involves identifying the cause of the crack and addressing any underlying issues that may be contributing to it. The next step is repairing the foundation crack.  The method used to repair the crack will depend on the size and severity of the crack, as well as the materials used in the construction of the foundation. Small cracks may be repaired using epoxy injection or other sealants, while larger cracks may require the installation of carbon fiber or steel reinforcement systems. Bigger cracks may require other, more extensive foundation crack repairs.

Basement underpinning is a method of strengthening and increasing the depth of a home's foundation. This process involves excavating the soil beneath the existing foundation and extending it downwards to create additional space or support. Watch our video on the basement underpinning process at Aquamaster.

Weeping tile, also known as drain tile or French drain, is a type of drainage system that is installed around the foundation of a building to prevent water from entering the basement or crawlspace.

A weeping tile system typically consists of a perforated pipe that is surrounded by gravel or crushed stone. The pipe is installed around the perimeter of the foundation, and any water that collects in the soil around the foundation is directed into the weeping tile and carried 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.
