Hamilton Interior Basement Waterproofing – Internal Solution

Interior waterproofing, also known as internal waterproofing, is the best way to cure leaks in your basement that originate from the interior of your home and is the finest solution for a damp or wet basement. When your basement gets wet and damp, it’s best to have internal waterproofing done because mould and mildew can grow there and create odours and bacteria that can be harmful to your health. This is an additional waterproofing solution that will help with the hydrostatic pressure buildup that causes a damp basement. Covering Hamilton and all of  Southern Ontario, RCC delivers interior waterproofing services to areas such as Toronto, Mississauga, Vaughan, London, Kitchener, and beyond.

The materials utilized in the waterproofing procedure include an internal air-gap drainage membrane, drainage tile (weeping tile), drainage tile connecting pieces, 3/4-inch gravel, and cement.

Interior Waterproofing Benefits

The internal system method may be the best option depending on these 3 reasons:

  1. The place is too small or inaccessible to be reached from the outside.
  2. Instead of a foundation leak, the water issue is caused by hydrostatic pressure, which occurs when groundwater beneath the concrete slab rises and falls and allows water to seep through the basement slab or the point where the wall meets the floor. This groundwater may also indicate the existence of an underground brook at the site of the house’s construction.
  3. The Internal System is an affordable way to complete living spaces.

Basement Waterproofing Is the Key To Preventing Mold and Promoting Air Quality

The presence of mold in your home can escalate into a significant issue, potentially leading to health concerns for occupants and gradual deterioration of affected areas.

Aside from causing irritation and posing health risks, molds can produce allergens, triggering allergic reactions in individuals who come into contact with or inhale mold spores. Individuals with bronchitis are particularly susceptible to mold growth and poor indoor air quality. Mold spores, which are tiny and invisible to the naked eye, exist in both indoor and outdoor air, facilitating mold growth on damp surfaces. Even minimal moisture from sources like dust or water is sufficient for mold to proliferate. Understanding these risks underscores the importance of addressing damp or wet basement conditions promptly.

Homeowners often postpone addressing water or moisture-related issues in their basements, but this can be a costly mistake. Water damage worsens over time, and allowing mold to develop can lead to long-term financial implications, including the cost of remediation and addressing associated health concerns.

If you suspect mold in your home, you may encounter the term “mold remediation,” referring to the process of resolving mold issues. Seeking the guidance of a qualified inspector is advisable, as mold is often unnoticed until it reaches an advanced stage. Certified mold specialists are equipped to handle mold issues in homes and stay informed about the latest products, techniques, and regulations.

Preventing mold formation is undeniably the best approach. Therefore, addressing any moisture or water-related issues promptly upon detection is essential to mitigate the risk of mold growth in your home.

Interior Drainage System Steps

The floor is broken around the perimeter, approximately 6 to 10 inches from the foundation wall, to accommodate the necessary system.

Concrete is then removed, and a trench is excavated to fit the 3-inch drainage pipe.

Perforated weeping tile is installed in the trench

The weeping tile is installed and must be connected to a discharge point, such as a sump pump or floor drain.

A dimpled drainage membrane is then applied to the interior exposed wall where the system has been installed.

Next, we lay down a layer of 3/4-inch clear gravel over the weeping tile to ensure optimal drainage.

Once the membrane and gravel are in place, they facilitate the drainage of water from both above and below grade into the installed system.

Following that, a layer of concrete is laid over the exposed trench to restore the floor to its original level.

Common Exterior Leak Problems

Floor and Wall

Implementing internal waterproofing solutions within your home can effectively redirect water entry to the designated disposal area. By installing an internal waterproofing system, you gain the primary benefit of preventing water from permeating through walls and beneath footings.

Our drainage membrane serves as an impermeable barrier, safeguarding your living space from water intrusion by diverting moisture away from basement walls. Any water that seeps beneath the footing, causing leaks and damp patches on the basement floor, is managed by the drainage board, which directs it towards newly installed weeping tiles for proper drainage.

Sump Pump

The cornerstone of any waterproofing system is establishing a means to discharge water. If alternative drainage options are unavailable or if the existing drainage system is blocked, your specialist may recommend the installation of a sump pump. At the lowest point of your waterproofing system lies a pit excavated within your basement. This pit is lined with a high-quality plastic liner, facilitating gravity drainage as water enters the pit.

Activated by a trigger mechanism, the sump pump detects water accumulation within the pit and expels it outside the house. We exclusively utilize top-notch plumbing supplies and sump pumps, including battery-operated backup pumps to ensure continuous operation in the event of power loss. Inquire with your sales representative about potential savings of up to $1750 on sump pump installations, as the City of Toronto is currently offering a subsidy.
