What is Basement Waterproofing?

Basement waterproofing is a procedure designed to prevent water from entering a building’s basement. The aim is to channel water away from the foundation of a property to prevent it from causing structural damage. Waterproofing can include a variety of techniques such as applying sealants on the interior and exterior of the basement, installing a proper drainage system, installing sump pumps, and remedying any foundational cracks or leaks. This process is crucial to maintaining the structural integrity of the building, preventing mold growth, and creating a dry, usable, and healthy space.

Foundation crack repair in waterproofing refers to the process of identifying and sealing cracks in the foundation walls or floor to prevent water infiltration. Over time, foundation walls can develop cracks due to various factors such as settling, shifting soil, or hydrostatic pressure. These cracks can allow water to seep into the basement, leading to moisture issues, mold growth, and potential structural damage. Foundation crack repair involves filling and sealing the cracks using specialized materials like epoxy or polyurethane injections to restore the integrity of the foundation and prevent further water penetration.

Waterproofing Products we Use in Gravenhurst

Waterproofing materials and quality workmanship allow us to give a 25-year warranty on our waterproofing.

The quality of basement waterproofing can depend on the quality of materials used. High-quality materials that are specifically designed for waterproofing purposes, such as durable waterproof membranes, sealants, and drainage systems, are more likely to provide effective and long-lasting protection against water intrusion.

These materials are typically resistant to moisture, capable of creating a reliable barrier against water penetration, and are less prone to deterioration over time. Conversely, using low-quality or substandard materials can compromise the effectiveness of the waterproofing system and increase the risk of water leaks or damage. Therefore, investing in high-quality materials is important for ensuring a reliable and durable basement waterproofing solution.

Frequently asked questions

Foundation cracks can be caused by a variety of factors, including:

  1. Soil movement: The soil beneath a building can shift and settle over time, causing the foundation to crack or shift. This is often due to changes in moisture content, temperature, or soil compaction.

  2. Water damage: Water can cause foundation cracks by exerting pressure on the foundation walls or by weakening the soil beneath the foundation. This can be caused by heavy rainfall, flooding, or a high water table.

  3. Poor construction practices: If the foundation was not properly constructed or reinforced, it may be more susceptible to cracking or shifting over time.

  4. Natural disasters: Earthquakes, hurricanes, and other natural disasters can cause foundation damage due to the forces exerted on the building.

  5. Tree roots: Large trees planted too close to a building can cause foundation cracks by drawing moisture from the soil and causing it to shrink and shift.

Overall, foundation cracks can be caused by a wide range of factors, and it is important to identify the cause of the crack in order to determine the appropriate repair method.

Basement leak detection typically involves a combination of visual inspection and the use of specialized equipment to identify the source of the leak. Some common methods of basement leak detection include:

  1. Visual inspection – a basement waterproofing contractor will inspect the interior and exterior of the building for signs of water damage, such as water stains, mold growth, or damp spots.

  2. Water testing – a contractor may perform a water test by spraying water around the exterior of the building and monitoring for signs of water penetration.

  3. Moisture meters: Moisture meters can be used to detect moisture levels in walls, floors, and other surfaces. High levels of moisture can indicate the presence of a leak.

  4. Infrared cameras: Infrared cameras can be used to detect temperature changes in walls and floors, which can indicate the presence of water.

Once the source of the basement leak is detected, the contractor can determine the appropriate repair method, which may involve injecting the basement wall or floor crack with epoxy solution, waterproofing the basement walls or installing a sump pump or other drainage system to prevent water from entering the basement in the future or to manage the water that has already made it into your basement.

Basement waterproofing can take anywhere from a couple of hours to weeks. This depends on the specific basement waterproofing solution you need. A simple foundation crack repair (by injecting an epoxy solution) can take a couple of hours, but if your project involves full-scale basement waterproofing, excavation, weeping tile installation and other services then our services are likely to take days or even weeks.
