How To Waterproof A Foundation

Step 1: 

Assess the Site Thoroughly inspect your foundation for any signs of existing water damage or entry points. These might include cracks in the foundation walls, gaps at joints, or places where pipes and utilities enter the house.

Step 2: 

Choose Your Materials Select a high-quality waterproofing membrane or coating. Options may include liquid membranes, sheet membranes, and bentonite panels, each with different application processes and benefits.

Step 3: 

Plan for Drainage Consider the installation of a proper drainage system, such as a French drain or a weeping tile system, which diverts water away from the foundation and is a critical step in a full waterproofing strategy.

Step 4: 

Perform the Application Waterproofing products should be applied strictly following the manufacturer’s instructions. It can involve painting or spraying the material on the foundation walls, or laying down and securing sheets of waterproofing.

Surface Preparation Procedure

Before waterproofing can begin, the surface of the foundation must be properly prepared to ensure the best results:

  1. Cleaning the Surface: Remove dust, loose particles, and debris to create a clean surface for the waterproofing material to adhere to effectively. This might involve brushing, power washing,
  1. Repairing Cracks and Holes: Fill any existing cracks or holes in the foundation using hydraulic cement or other appropriate filler. Allow adequate time for these repairs to cure before applying the waterproofing material.
  2. Smoothing the Surface: If necessary, smooth out rough or uneven areas to create a flat surface. This can involve applying a layer of mortar to the foundation walls and allowing sufficient time for it to set.
  3. Applying Primer: Some waterproofing systems require a primer to be applied before the main coating. Check with the product specifications and apply as directed.

By following these steps, homeowners can make informed decisions and carry out the foundation waterproofing process with greater success. And, when expert input is required, Frontiers Foundation Repair & Basement Waterproofing seasoned professionals are just a call away to ensure your home remains dry and secure.

Damp Proofing VS Waterproofing Foundations


Damp Proofing



Applying a moisture-resistant coating to prevent dampness from soil moisture.

Applying a full-proof barrier designed to prevent water and moisture penetration, including against hydrostatic pressure.

Materials Used

Typically tar-based or a simple cementitious coating.

Includes liquid membranes, sheet membranes, bentonite panels, crystalline sealants, and more.


Effective against soil moisture and dampness.

Effective against both moisture and liquid water, including heavy rains and high water table situations.


Less durable and may deteriorate over time.

More durable with longer life span and often comes with a warranty.


Generally less expensive as it provides a minimal level of protection.

Typically more expensive due to higher material costs and more complex installation.


Usually applied internally on foundation walls or on the exterior without excavation.

Often requires exterior application with excavation around the foundation for comprehensive coverage.


Might require more frequent checks and touch-ups.

Requires minimal maintenance given its robust application.

Exterior Foundation Waterproofing

The best waterproofing approach starts from the outside. By applying a protective barrier to the exterior walls of your foundation, you block water from making its first contact with your house. This process typically involves excavating around the home’s foundation, applying a waterproof coating, and installing a drainage system like a weeping tile or French drain to redirect water away from the foundation.

Interior Waterproofing

Sometimes, water finds its way indoors despite exterior protections. This is where interior waterproofing steps in, featuring methods like sump pump installation, the application of interior sealants, and the installation of interior drainage systems to address water that permeates the foundation walls.

Foundation Crack Repair

Cracks in the foundation are inevitable over time but leaving them unchecked can lead to serious water intrusion problems. Professional repair involves identifying the source and type of crack, then sealing it with materials such as epoxy or polyurethane foam, ensuring a water-tight seal.

Regular Maintenance: The Key to Lasting Waterproofing

For effective foundation waterproofing, simple routine maintenance includes:

  • Clearing Systems: Regularly clean gutters and drains to prevent backups that could affect the foundation.
  • Sump Pump Tests: Check and test your sump pump routinely to ensure it’s ready for rain seasons.
  • Crack Monitoring: Inspect your foundation for new cracks or moisture and address issues promptly.
