  • Pros: Effective for managing water that has already entered the basement. Typically less disruptive to the landscape.
  • Cons: Does not prevent water from penetrating the foundation.
  1. Exterior Waterproofing
  • Description: Focuses on preventing water from entering the basement by applying waterproof coatings and installing drainage systems on the outside of the foundation.
  • Pros: Provides a barrier against water intrusion. Addresses issues at the source.
  • Cons: Can be more invasive and expensive. Requires excavation around the foundation.
  1. Cavity Drain Membrane Systems
  • Description: Involves the installation of a membrane on the interior walls to manage and redirect water to a drainage system.
  • Pros: Allows for continuous monitoring and maintenance. Provides a controlled drainage path.
  • Cons: Relies on the effectiveness of the drainage system.
  1. Crystalline Waterproofing
  • Description: Application of crystalline substances to concrete surfaces, creating a barrier against water penetration.
  • Pros: Becomes an integral part of the concrete structure. Durable and resistant to wear.
  • Cons: Application can be challenging. Effectiveness may vary based on the concrete quality.

Pros and Cons of Each Method


  • Interior waterproofing is effective for managing existing water issues.
  • Exterior waterproofing prevents water intrusion at the source.
  • Cavity drain membrane systems provide continuous monitoring and controlled drainage.
  • Crystalline waterproofing becomes a lasting part of the structure.


  • Interior waterproofing does not stop water from entering the foundation.
  • Exterior waterproofing can be invasive and costly.
  • Cavity drain membrane systems rely on the efficiency of the drainage system.
  • Crystalline waterproofing applications may pose challenges.

Choosing the right waterproofing method depends on factors such as the severity of water issues, budget constraints, and personal preferences. Consulting with a waterproofing professional can provide valuable insights tailored to your specific situation, ensuring that you make a decision that aligns with your long-term protection goals.
