Keep your basement dry and protected against water damage

Water in your basement can lead to mold, structural issues, and costly repairs.

At Chicago Basement Systems, we design and install custom interior drainage solutions for homes in Naperville, Chicago, Aurora, and surrounding areas in Illinois & Indiana.

Why install an interior French drain?

A French drain (also called drain tile, weeping tile, or perimeter drain) is a system that includes a perforated pipe and drainage stone that collects water and redirects it away from your foundation. While many people think of an exterior French drain, Chicago Basement Systems installs interior French drains, which are less invasive, easier to maintain, and highly effective at keeping basements dry.

Benefits of our interior drainage systems:

  • Captures water at the most common entry points, including the floor/wall joint and beneath the basement floor (sub-floor drainage)
  • Patented interior drainage channel design helps prevent clogs and ensure consistent water flow
  • Most installations can be completed quickly with minimal disruption
  • Can be installed and serviced year-round in any weather conditions
  • Minimally invasive — no major yard excavation required
  • Prevents basement flooding, water intrusion, and structural damage
  • Reduces hydrostatic pressure around your foundation
  • Protects your walls, floors, and overall structure from moisture-related issues
  • Helps maintain a dry, healthy basement for storage or living space
  • Different systems can address unique challenges, including iron ochre, thin floors, or monolithic foundations

Our interior drainage system installation process

  1. Preparation: A small section of the basement floor is removed if needed.
  2. Installation: Patented drainage channels are installed along the interior perimeter of the foundation.
  3. Flow management design: Drainage stone ensures water moves freely to a sump pump.
  4. Concrete floor restoration: Floor is restored, repaired, or replaced as needed.

Our foundation drainage products & systems

At Chicago Basement Systems, no two basements are alike. That's why we offer a full range of patented interior drainage systems. For most homes, we recommend our WaterGuard® sub-floor drainage system. Other systems are available for specialized situations.

WaterGuard® Sub-Floor Drain

WaterGuard® French Drain System in Chicago

For a typical basement, our WaterGuard® system is the ideal choice for waterproofing. This French drain collects water that seeps through basement walls and drains it to your sump pump.

WaterGuard® is designed to be installed below the floor slab on top of the foundation footing. The sub-floor drainage system is installed with minimal invasion of the slab, and all concrete is restored after installation.

DryTrak® Baseboard Drain Pipe

DryTrak® French Drain System in Aurora

If your house has a monolithic foundation — or a foundation that comes with the floor and footing as one piece — we use our DryTrak® system. This system installs over the top of the floor, eliminating the need for excessive excavation.

FlowGuard® Thin Floor Drain System

FlowGuard® French Drain System in Mokena

Sometimes the concrete floor in a basement is too thin for a drain to be installed on top of the footer — we address this challenge with our FlowGuard® system. This system is designed to sit in front of the footing in a bed of drainage stone. After installation, the concrete floor is restored over the drain.

WaterGuard® IOS Iron Ochre Perimeter Drain

WaterGuard® IOS Basement Drain in Shorewood

If iron bacteria is present in your water, it will create a gelatinous, rust-colored substance known as iron ochre. This material is notorious for smelling terrible, staining everything it touches, and clogging drainage systems. Our experts tackle this rare problem with our WaterGuard® IOS Basement Drain.

This product is a modified version of our WaterGuard® system that includes an extra-wide drain channel, larger drainage openings, and a removable lid to allow for easy maintenance if clogged. This system will protect your home from iron ochre while helping prevent any water from seeping into your basement.

TrenchDrain™ Grated Drain Pipe

TrenchDrain™ Grated Drain Pipe in Bolingbrook

For many homeowners, preventing flooding from an outer entryway such as a hatchway, garage door, or doorway is a priority. In this case, we use the TrenchDrain™ Grated Drain Pipe to span the opening and prevent water from flowing into your basement. The grated opening of this system is designed to accept water from the floor, where it's then redirected to your perimeter drain and your sump pump.

TrenchLock™ Drain Inserts

TrenchLock™ in Kankakee

Trench drains have the unintended consequence of allowing air from drainage channels and the ground into the home. This air may contain hazardous radon gas, a naturally occurring radioactive gas. TrenchLock™ is an insert that can be installed in an existing trench drain to allow water down without allowing unwanted ground air to come up and enter your home.


Foundation drainage system questions & answers

Do interior French drains really work?

Yes, interior foundation drainage systems address the most common causes of basement water problems, including hydrostatic pressure and wall/floor joint leaks. This system keeps basements dry without the need for exterior excavation.

How long does a French drain last?

With proper installation and maintenance, our patented systems provide long-term protection. The WaterGuard® system is backed by a lifetime transferable warranty, giving added confidence and value for your home.

How much does an interior French drain cost?

The cost of installing an interior waterproofing system depends on your basement size, foundation type, and water issues. During a free estimate, our basement waterproofing professional will provide you with a customized quote.

Where does the water in an interior French drain go?

Collected water is directed to a sump pump, which safely discharges it away from your foundation.

Interior vs. exterior French drain: which is better?

Interior French drains are installed inside the basement along the perimeter. They collect water at the floor/wall joint, wall cracks, and beneath the slab and direct it to a sump pump. Interior drains are less invasive, easier to maintain, and effective year-round.

Exterior French drains are installed outside the home and redirect water before it reaches the foundation. They may be necessary for severe grading problems or foundation wall issues but require more excavation and can disrupt landscaping.
