What is basement waterproofing?

Waterproof Basement is the best way to prevent floods and water damage in your basement in your house. It is effective method of channeling water from the outside and preventing any leaks in the basement walls and flooring.

Basements are more prone to moisture than other areas of the house. They are below grade, so hydrostatic pressure can push groundwater through any porous surface or small fissure in the walls or floor. Moreover, basements are usually poorly ventilated, which makes them vulnerable to humidity and condensation. A damp basement is usually a moldy one, and when things get really bad, water can even pool on the floor and provide a breeding ground for pathogens.

When moisture becomes a problem, it’s important to determine whether the water is coming from outside or inside, because the remediation strategies are different. When water is coming from outside, the best strategy is usually to improve drainage around the exterior of the house, although you may be able to block seepage to a degree by making indoor repairs, such as patching cracks and plugging holes. If condensation is the culprit, you’ll probably want to improve ventilation and add insulation to the walls to reduce the temperature differential that causes condensation to form. In extreme situations in which water actually pools on the floor, you may need to control it with a pump.

Tornado Plumbing professionals will design a custom solution that will be most efficient for your safe basement waterproofing. It should be done differently depending on conditions and the cause of the issue. Sometimes it’s required to install a drainage system with sump pump in the sub-floor. In other cases, we would have to excavate the outside of the wall and waterproof the foundation. To make your crawl space more environment friendly we may install a vapor barrier or drainage system.


Few reasons why the water is seeping into your basement:

  • Rainwater is entering somewhere through the foundation walls.
  • Rain Water seeping through foundation crack might be leaking inside your basement
  • When your home relies on a weeping tile drainage and sump pit, you need a sump pump to drain the water.
  • Openings due to the poor blended cement on the foundation floor and walls.
  • The water pressure beneath the house creates floor cracks.
  • Wear and tear of joints connecting the main and sewer lines.
  • Having eavtroves and downspouts connected in the sanitary drainage; will also lead to an excess of water flow through the system, leading to a backup.
  • Basement wall and floor drainage problems.
  • Floor drains are mainly common in older homes, but also new build homes have them as well.
  • When open floor drain becomes clogged the wastewater from your sink or washer will not be capable to drain away, and will cause backup in your basement.
  • Your home relies on a weeping tile drainage and sump pit

In fact, 60% of homes today have moisture problems, which is why waterproofing is so important.

Types Of Basement Waterproofing and Flood Prevention

  • Exterior basement waterproofing, referring to the process in which a bonding substance or foundation membrane is applied to the outside walls of your basement.
  • Interior basement waterproofing, used to keep moisture from making its way into your basement through a drainage system applied on the walls and floor to direct the water beneath the floor into the weeping tile.
