Basements, being the unassuming heroes of our homes, are rarely credited for the crucial role they play in our homes. They serve a variety of roles such as providing extra space for storage, bringing utilities, and becoming a living space that you can find very comfortable.

But there’s one common enemy that threatens the integrity of basements: water. Whether it’s seeping through cracks or flooding during heavy rains, water can wreak havoc on your basement. That’s where basement waterproofing comes in.

This post will walk you through three primary approaches of basement waterproofing, preventing your space from water damage, dampness, and any other related challenges.

Approach 1: Exterior Basement Waterproofing

What Is It?

It’s like wrapping your basement with a waterproof raincoat to keep it dry. It involves treating the exterior of your foundation walls to prevent water infiltration. Here’s how it works:

Excavation: The contractors dig trenches around the house, and expose the foundation walls.

Surface Preparation: The walls are washed and inspected for holes, cracks, and other damages.

Application of Waterproofing Membrane: The foundational walls are lined with a thick rubber sealer which acts as a barrier against water infiltration.

Drainage System Installation: A French drain or other drainage system is introduced so that water could be diverted away from the foundation.

Backfilling: The soil that has been excavated is replaced, and life is restored in the landscape.


Effective: The exterior waterproofing works to solve the problem at the source.

Long-Lasting: Ensures enduring protection for your building.

Prevents Structural Damage: It safeguards your foundation by preventing water infiltration.

Approach 2:  Interior Basement Waterproofing

What Is It?

Interior basement waterproofing aims to tackle infiltrated water within the basement. It’s like having your sump pump as a good umbrella. Here’s how it works:

Interior Drainage System: An entire perimeter drain, frequently referred to as the French drain, is installed along the inside of basement walls.

Sump Pump Installation: A sump pump collects water from drains and pumps it out of  your home.

Sealing Cracks and Holes: Every existing crack or hole is sealed with a watertight seal to prevent further penetration of water.

Waterproof Coatings: Special coatings can be used to keep the walls dry.


  • Cost-Effective: The price tag for interior waterproofing is lower compared to the exterior one.
  • Less Disruptive: No need for deep digging operations.
  • Works Well with Existing Basements: Perfect for improving your older basements

Approach 3: Hybrid Basement Waterproofing

What Is It?

Hybrid basement waterproofing is a versatile superhero to protect your basement. This innovative basement waterproofing approach combines both interior and exterior basement waterproofing techniques to offer enhanced protection. Here’s how it works:

Exterior Treatment: The contractors start digging around the foundation similar to the exterior waterproofing. By applying waterproofing membrane and installing drainage systems, they are able to prevent any possible water penetration.

Interior Enhancements: And after that, they pay attention to the interior decoration. Interior and exterior waterproofing are applied, sealing the perimeter drain and setting up the sump pump.

Sealing Cracks and Coatings: Pre-existing cracks will be sealed off, and water-proof covering would be put on the interior walls to prevent any moisture penetration.


Double Protection: Hybrid waterproofing is the effective solution for eliminating water at both inside and outside the building.

Customizable: Contractors can choose from a variety of ways that cater to your needs and budget.

Peace of Mind: You will have a peace of mind that your basement is well-guarded against all odds.

  12. Home Inspection Reports: A home inspection report, which is worthy of your trust, is a must-have in the process of buying or selling a home.
  13. Stay Updated: Keep an eye on structural engineering trends that can provide innovative options.
