The Science Behind Polyurethane Foam

Polyurethane grouts are advanced, man-made polymers that react with moisture upon injection into the ground. This reaction causes the material to expand and harden into a stable, water-resistant mass, effectively filling voids and reinforcing structures.

Expands into empty spaces, preventing settling, erosion, and shifting.

Creates a denser, more stable foundation to prevent future movement.

Bonds loose particles together, reinforcing the ground for long-term stability.

Forms a water-tight barrier, stopping leaks and preventing future water intrusion.

Reduces soil permeability, lowering risks of erosion and instability, especially in seismic zones.

Requires no major excavation, protecting the environment while reducing landfill waste.

Polyurethane injection foam is utilized across various sectors for multiple purposes:

Ideal for sidewalks, driveways, warehouse floors, and patios.

Prevents erosion and strengthens the ground beneath buildings and roadways.

Expands into cracks and voids to create a permanent, water-resistant seal.

Stabilizes old mine shafts, decommissioned septic tanks, abandoned pipes, and more.

NSF/ANSI/CAN 61 certified, making it safe for use around potable water sources.

Upon injection, polyurethane foam:

Bonds them into a firm matrix.

Removes moisture from eroded zones, preventing further degradation.

Addresses spaces caused by organic decay or poor compaction.

Adheres directly to soil particles, resulting in permanent, maintenance-free stabilization with exceptional compressive and shear strength.

Considerations & Additional Information
Exterior Drain System

An exterior drain system is a proactive waterproofing solution installed outside your home to manage groundwater and protect your foundation. Often referred to as perimeter drains, French drains, or footing drains, these systems are located at the base of your foundation to redirect water away from your home.


By preventing water from pooling around your foundation, exterior systems reduce hydrostatic pressure and help avoid leaks and water intrusion. However, these systems require routine maintenance and can fail over time if not properly maintained, especially when gutters, downspouts, or drainage pipes become clogged or damaged.


Interior Drain Tile System
An interior drain tile system is a comprehensive waterproofing solution designed to capture and manage water that bypasses exterior systems or isn’t diverted by other preventive measures like gutters. Installed along the interior perimeter of your basement, this system collects water that seeps through the foundation or walls and redirects it to a sump pump or drainage outlet.

By preventing water from pooling inside your basement, interior systems protect your foundation from water damage and keep your basement dry. These systems are engineered to provide long-term protection and can handle water even when exterior defenses fail.

How much does it cost to install an interior drain tile system?

Are your Basement Drainage Solutions warrantied?

Absolutely! We stand behind our workmanship and materials. Learn more about our warranties.

Will there be additional costs if extra repairs are needed during installation?

If we identify additional repairs, we’ll pause the installation, discuss the findings, and provide a transparent quote before proceeding.

Is a basement drainage system the right solution for my water problems?

Our experts will assess your basement’s unique needs during your consultation to determine if an interior drain tile system is the best fit. We take an honest, tailored approach to basement waterproofing.

Will installing a foundation drainage system stop water from entering my basement?

An interior drain tile system manages and redirects water that enters your basement, preventing pooling and protecting against long-term damage.

Can this system be installed in a finished basement?

Yes! While some preparation like removing drywall or flooring may be necessary, we strive to minimize disruption.

Will the system help reduce mold and mildew in my basement?

While we are not mold specialists, a dry basement is essential for preventing mold growth. Our drainage systems help maintain a healthier environment.

What are the signs that I need an interior drain tile system?

Common signs include:
• Water leaking at the wall/floor joint (not from a crack or rod hole).
• Persistent dampness or water seepage.

How can I confirm water is entering my basement before investing in this system?

Perform a water test by running water from a hose at the exterior foundation and checking for damp areas inside. View our water test guide for step-by-step instructions.

Will installing the drainage system damage my basement floors or walls?

Minimal disruption is expected. We’ll protect walls with a waterproofing membrane and cover the trenched areas with a thin layer of concrete.

How long does it take to install a basement drain tile system?

Most installations take 1–3 days, depending on the basement size and complexity of the drainage system.

Who can I contact if I have questions or issues after installation?

Our team is here to help! Call, text, or email us with any concerns before, during, or after installation.

Foundation Footings: 

Your foundation footings are critical to the stability of your home. These wide, concrete slabs bear the weight of your home and must remain free from water damage.

Our team trenches down to the footings during installation, ensuring optimal water management and protection for your home's foundation.

Sump Pump and Basin:

A sump pump collects and removes water from your basement, working alongside the drain tile system to prevent flooding. The sump pump basin holds collected water, activating the pump when needed to discharge water away from your home.

An interior drain tile system works effectively only when the collected water has a proper outlet. This is why having a sump pump and basin is essential, particularly when a suitable bleeder line cannot be found or securely tied into.​

Bleeder line: 

A bleeder line (or interior drain pipe) helps manage water around your foundation by directing it to the sump pump or another drainage outlet.

When a functional bleeder line is available, we can integrate it into your system, saving you the cost and maintenance of installing a new sump pump.

To ensure a thorough and accurate assessment, please take the following steps:


Clear Access: 

Providing clear access to your basement’s foundation walls is essential for a complete assessment. This allows the technician to identify signs of water damage and recommend the most effective solution. Be sure to remove drywall, paneling, furniture, storage units, boxes, and any wall-mounted items to give the technician full visibility. For detailed instructions on how to prepare your basement, visit our guide: [link].


Locate Leaks: 

If you’ve noticed any visible leaks or water stains, mark those areas on your basement floor and walls. This ensures that the technician can focus on these areas and assess the condition of your foundation.

Pro Tip: Use chalk, crayons, pencils, or tape to mark these spots. These tools are temporary and will not damage your surfaces.

By preparing your basement ahead of time, you’ll help the technician conduct a more effective evaluation, which leads to a more accurate estimate for your interior drain tile installation.

Proper preparation helps to ensure a smooth and efficient installation.

  • Clearance: We require a 4-foot clearance from the basement wall towards the center of the basement along the entire path of the drain tile. This allows our team ample space to work comfortably and efficiently.


  • Basement Items: Please remove any furniture, boxes, or other items currently within the 4-foot clearance area.


  • Wall-Mounted Items: Temporarily remove any shelves, cabinets, or other items attached to the walls along the installation path.


  • Drywall/Paneling Removal: Ensure drywall or paneling along the installation path is removed before the appointment.


  • Plumbing items: Remove plumbing items like washers, dryers, laundry tubs, and toilets to allow clear access to the installation area.


  • Large Household Items: Plan to move heavier items such as furnaces, water heaters, and ductwork the day before your scheduled appointment.

Note: Any specific items over and beyond this list will be noted on your estimate and should be addressed prior to your installation date.

Keep your interior drain tile system working efficiently and maintain your warranty with these simple steps:


  • Avoid damaging the concrete: The concrete near your drain tile system is thinner to accommodate the system.. Do not drill, hammer, or screw into this area to prevent system damage.
  • Protect the wall membrane: Don’t puncture the waterproof membrane on the walls with screws, nails, or drills to prevent future leaks.

Following these guidelines will ensure your basement waterproofing system functions effectively for years to come.
