Water can seep into your foundation and cause a wide range of problems, including mold growth and structural damage. This is where drain tile systems come into play. In this blog post, we will discuss interior and exterior drain tile systems and how they can benefit your home.

What is a Drain Tile System?

A drain tile system, also known as a French drain or footer drain, is a system designed to collect and redirect water away from your home’s foundation. The system consists of a perforated pipe surrounded by gravel or rock that allows water to flow through and be directed away from your property.

Interior Drain Tile System

An interior drain tile system is installed underneath your basement or crawlspace floor. This system is designed to collect water that seeps through the foundation walls or floor and direct it to a sump pump. The pump, in turn, will remove the water from your home, preventing any damage or flooding. Interior drain tile systems are commonly used in homes with basements or in areas with high water tables.

Benefits of Interior Drain Tile Systems:

– Prevents basement flooding: By collecting and redirecting water away from your home’s foundation, an interior drain tile system can prevent costly basement flooding incidents.

– Protects against mold and mildew: By removing excess moisture, these systems can help prevent the growth of mold and mildew, which can be harmful to your health and cause damage to your home.

– Preserves the structural integrity of your home: Water can compromise the integrity of your home’s foundation, leading to cracks and other issues. An interior drain tile system helps protect against this by keeping water away from the foundation.

Exterior Drain Tile System

An exterior drain tile system is installed around the perimeter of your home’s foundation. This system is designed to collect water that accumulates around the foundation and direct it away from your property. The system consists of a perforated pipe surrounded by gravel or rock, preventing water from seeping into the foundation.

Benefits of Exterior Drain Tile Systems:

– Prevents water damage: By redirecting water away from your foundation, these systems can prevent water from seeping into your basement or crawlspace and causing costly damage.

– Protects against soil erosion: Continuous exposure to water can lead to soil erosion around your foundation. An exterior drain tile system helps maintain the stability of the soil, preventing erosion and potential foundation issues.

– Increases the lifespan of your foundation: By keeping water away from your foundation, an exterior drain tile system helps prevent water-related damage, prolonging the lifespan of your foundation.

Choosing the Right System for Your Home

When it comes to choosing between an interior and exterior drain tile system, it depends on the specific needs and characteristics of your home. Homes with basements or high water tables are better suited for interior drain tile systems, while homes with poor drainage or outdoor water issues benefit from exterior drain tile systems. Consulting with a professional contractor or drainage specialist can help you understand your options and make an informed decision.


Investing in a drain tile system is crucial to safeguarding your home against water damage. Whether you opt for an interior or exterior system, the benefits are numerous. These systems protect your foundation, prevent basement flooding, and offer peace of mind during heavy rain or melting snow. Consider consulting with a professional to determine the best drain tile system for your home to protect it from water-related issues for years to come.
