Why Choose Interior Waterproofing Over Exterior Waterproofing?

Interior waterproofing provides targeted solutions for your home’s water infiltration challenges. Here’s why it’s the preferred choice:

  • Cost Savings: It’s generally more cost-effective in comparison to exterior waterproofing due to reduced excavation and landscaping expenses.
  • Precise Sealing: Interior waterproofing targets and seals cracks and holes inside your home, effectively preventing water entry.
  • Concrete Protection: With most foundations made of porous concrete, interior waterproofing directs water away from your home’s interior.
  • Value Preservation: It safeguards your property’s value by preventing costly issues like structural damage and mold growth.
  • Mold Prevention: Interior waterproofing ensures a mold-free environment, preserving indoor air quality and health.
  • Structural Integrity: By addressing water intrusion at its source, it protects your home’s structural integrity and building materials.

Signs You Need Interior Waterproofing

  • Damp or Moldy Odors: If you detect a musty or moldy odor in your basement or other interior spaces, it’s often an indicator of excessive moisture and potential water infiltration.
  • Visible Water Stains: Water stains on walls, floors, or ceilings are clear signs of past or ongoing water intrusion. These stains may appear discolored, and they often signal the need for interior waterproofing.
  • Cracks in Walls or Foundation: Cracks in interior walls or the foundation can allow water to seep into your home. If you notice these cracks, especially if they’re accompanied by dampness, they should not be ignored.
  • Efflorescence: Efflorescence is a powdery white substance that forms on walls or surfaces when water evaporates, leaving behind mineral deposits. It’s a sign of moisture infiltration and can indicate the need for waterproofing.
  • Pooled Water or Dampness: Puddles of water, damp spots, or even consistently high humidity levels in your basement suggest a moisture problem that requires attention.
  • Peeling Paint or Wallpaper: Moisture can cause paint or wallpaper to peel, blister, or bubble. If you notice these issues, it could be due to water-related problems.
  • Bowing or Buckling Walls: Walls that are bowing inward or buckling are often a result of hydrostatic pressure from water in the soil surrounding your foundation. Interior waterproofing can alleviate this pressure.
  • Sump Pump Overuse: An excessively active sump pump is a sign that water is frequently infiltrating your basement. This indicates the need for a more comprehensive interior waterproofing solution.
  • High Humidity Levels: Consistently high humidity levels in your basement can lead to mold growth and other moisture-related problems, highlighting the need for interior waterproofing.
  • Visible Mold or Mildew: The presence of mold or mildew on walls, ceilings, or other surfaces indicates a moisture issue that should be addressed promptly to prevent health hazards and structural damage.
If you observe any of these signs in your home, it’s essential to consult with a professional interior waterproofing expert. Addressing these issues early can help prevent further damage and ensure the long-term health and integrity of your property.

Procedure On How Interior Waterproofing Is Performed

You will need a long lasting interior waterproofing solution that will provide you with full protection against a wet, damp basement – unless it’s just a small crack in the foundation. All of our jobs are personalized according to the needs of your home – the following is an overview of the primary procedure:

Wet Basement Repair
Excavating the Trench for the Weeping Tile

Concrete and flooring around the perimeter will be broken down, and debris will be cleared out from the area. This will allow Aquatech to excavate the interior of your home with a trench that is not too deep but also allows us to install the weeping tiles into the hole.

The Wall is Drilled for Holes
Interior Waterproofing Solutions

In the walls, holes are drilled which serve a specific function – this will allow the water that is trapped to be easily drained away to allow drying.

Wall Cracks are Fixed

Cracks or gaps in the basement walls are repaired and in many cases this will only require a water-tight sealant. If the gaps or cracks are large, Aquatech will use hydraulic cement in order to restore the wall integrity and ensure that anymore water does not get through.

Installing the Delta Membrane

For the walls, a delta drainage membrane is applied which stops any water, dampness, or mold from getting into the interior of the building. This helps water to flow away into the weeping tile draining, and supporting pump systems.

Installing the Sump Pump

Connecting into a sump basin, the weeping tiles allow water to flow. When this system activates, the water will flow into a pump, and will pumped outside of your home to be releases into a different location away from the home.

Installing the Basement Weeping Tile
Battery Backup Installation

The weeping tiles are placed and installed, which are high quality piping modules that allow water to divert away from the home.

Laying Down the Cement
