The AquaStop BasementGutter is a below-floor interior drain installed just above the basement footing. Groundworks places the system above the footing’s mud zone — the lowest area most likely to collect silt. This design helps reduce the risk of clogging that can affect some traditional footing-level drains.
The channel collects water that runs down basement walls or enters at the wall-floor joint, then moves it to a sump pump that discharges it away from your home. A wall flange directs wall seepage into the drain, making this system a good fit for basements with ongoing perimeter moisture rather than just one wet spot. Installation happens inside the basement, so there is no need to dig around the outside of the foundation.
Why Homeowners Consider the AquaStop BasementGutter
Homeowners usually consider this system when basement seepage keeps coming back after heavy rain, snowmelt, or seasonal groundwater pressure — especially if sealing cracks or improving grading has not worked. Since the drain covers the entire interior perimeter, it manages water at the entry point instead of trying to fix each leak separately.
Damp or musty odors that keep coming back after drying out
Pooling water during or after heavy rain
Mold growth or signs of persistent moisture damage on framing or insulation
Visible seepage near wall-floor joints or foundation cracks
An older waterproofing system that no longer keeps up with seasonal moisture
What Sets AquaStop BasementGutter Apart?
Groundworks offers AquaStop BasementGutter as part of a complete basement waterproofing system, not just as a standalone product. The most important features for homeowners to consider are:
Interior perimeter design: Installed along the inside edge of the basement to capture water where it most often enters — at the wall-floor joint and along the base of basement walls.
Above-footing placement: Positioned above the footing’s mud zone to help prevent clogging from silt, which is a known problem with some traditional footing drains.
Wall flange detail: Designed to guide water running down basement walls into the drain channel instead of letting it collect at the base of the wall.
Sump pump compatibility: Made to work with a sump pump so that collected water is pumped away from the foundation.
System integration: Often used together with vapor barriers, dehumidifiers, and sump pump systems as part of a complete waterproofing plan.
How Much Does AquaStop BasementGutter Cost Installed?
Most homeowners spend between $4,000 and $12,000 for a professionally installed interior perimeter drainage system. The lower price applies to a simple, unfinished basement with easy access and an existing sump pump. The higher price reflects a finished basement that needs demolition, careful repairs, and a new or upgraded sump pump.
Rather than focusing on cost per linear foot, it is better to consider the total project scope. The main factors that affect price are:
Basement perimeter length and square footage
Amount of trenching and concrete removal required
Whether a new sump pump or pit is needed
How much finish material — such as flooring, framing, or drywall — needs to be removed and replaced
Site access conditions and labor rates by region
Groundworks gives pricing only through in-home estimates, and there are no online quotes. Financing is available through third-party lenders at many locations. Be sure to confirm the annual percentage rate (APR) before you sign.
How Installation Works
Groundworks or one of its regional subsidiaries handles the installation. Since the system is installed from inside the basement, there is no need for exterior excavation. Homeowners should still expect some disruption to the basement during installation. A typical project includes:
Basement inspection and moisture pattern assessment
Project design based on where and how water is entering
Perimeter trenching along the basement edge
Drain channel and wall flange installation
Sump pump connection or upgrade, when needed
Concrete patch-back to restore the floor surface
Most installations take one to two days for a standard unfinished basement. Finished basements that need demolition and repairs will take longer. Groundworks will provide a project-specific timeline with your written estimate.
Compatibility and Ownership Considerations
AquaStop BasementGutter is one part of a larger waterproofing system and is not a complete solution on its own. In many homes, the drain works together with a sump pump, discharge line, vapor barrier, or dehumidifier. If your basement has several sources of moisture, you will likely need more than one product.
It is also important to understand what this system cannot do. An interior perimeter drain manages water that gets into the basement, but it does not stop water from entering. It is not a replacement for fixing exterior grading, improving gutters and downspouts, or repairing structural cracks if those are the root causes of water problems. A thorough inspector will tell you if these issues need to be addressed alongside, or instead of, installing an interior drain.
When This System Makes the Most Sense
AquaStop BasementGutter is typically a strong fit for:
Basements with recurring seepage at the perimeter that has not responded to simpler fixes
Homes in wetter climates or areas with seasonal groundwater pressure against the foundation
Finished or partially finished basements where moisture control protects a meaningful investment
Homeowners who want a contractor-installed interior drainage solution tied to a sump pump and backed by a warranty
When It May Be More Than You Need
This system may be more than you need if the moisture problem is limited to one fixable issue, such as a single crack, a misaligned gutter downspout near the foundation, or poor grading on one side of the house. Fixing the source directly may cost much less and solve the problem without a full interior drain system.
It may also be unnecessary if your basement only has mild, occasional dampness, there is no finished space to protect, and you plan to sell your home soon. In these situations, a less expensive fix or simply disclosing the issue to buyers may be more practical.
Warranty and Support
Groundworks supports its waterproofing installations with a transferable warranty that can be passed to new owners when you sell your home. Warranty terms can vary by project, location, and the specific components installed, so ask for the written warranty details before signing and confirm:
What is covered for the drain channel itself versus connected components like the sump pump
Whether the warranty covers both materials and labor
How to initiate a warranty service call and what response time to expect
Some customers have reported difficulty scheduling warranty service with Groundworks at certain locations. To avoid this, get the warranty response process in writing before installation begins. For more details on warranty performance, see our full Groundworks review.
How AquaStop BasementGutter Compares
AquaStop BasementGutter is best compared to other common basement water management solutions. The right choice depends on where water is getting in, how often it happens, and whether you need to protect finished areas.
Solution
How It Works

Limitations
Typical Cost
Groundworks AquaStop BasementGutter
Interior perimeter drain above the footing that collects wall and wall-floor joint seepage and routes it to a sump pump.
Recurring perimeter seepage; ongoing moisture control needs.
Requires interior trenching and concrete patch-back. Works best as part of a full waterproofing system.
$4,000 to $12,000
Exterior Footing Drain / Excavation
Excavates around the foundation exterior to install or replace drainage and block groundwater before it enters.
Major exterior drainage failures; persistent hydrostatic pressure.
Most invasive and expensive option. Disrupts landscaping and exterior access.
$6,000 to $15,000+
Crack Injection / Localized Repair
Seals one crack or isolated leak point rather than managing full-perimeter water intrusion.
Single-point leaks with a clearly identified source.
Insufficient for basements with seepage in multiple areas or along the full perimeter.
$300 to $2,500
Grated Drain / Surface Collection Drain
Captures surface water at one predictable entry point such as a stairwell or entry door.
Localized surface water at a single entry point.
Not a substitute for a full perimeter drain when moisture enters along walls and wall-floor joints throughout the basement.
$500 to $3,000
AquaStop BasementGutter is a good choice if you have ongoing perimeter seepage and want a contractor-installed interior drainage system that works with a sump pump. It offers a more complete solution than a single repair, but is less invasive and less costly than excavating the outside of your foundation.
For many homeowners, a professionally installed interior perimeter drainage system falls around $4,000 to $12,000. Price depends on basement size, trenching and concrete work, sump pump needs, and how much finish material must be restored after installation.
How does AquaStop BasementGutter work?
AquaStop BasementGutter is installed along the inside perimeter of the basement. It is designed to collect water entering from basement walls and wall-floor joints, then redirect that water to a sump pump for discharge away from the home.
Is AquaStop BasementGutter worth it?
It can be worth it for homeowners dealing with repeated perimeter seepage, especially if the goal is to protect a finished basement or reduce recurring moisture problems. It is less compelling when the issue is isolated to one crack or one exterior drainage problem that can be fixed more directly. This is an editorial judgment based on the product’s intended use and common waterproofing decision logic.
Does AquaStop BasementGutter require a sump pump?
In practice, systems like this are designed to work with a sump pump because the collected water needs a discharge path away from the foundation. If a home does not already have a suitable sump setup, that may be part of the recommended scope.
Is installation disruptive?
Installation is less invasive than exterior excavation, but it is still a meaningful interior project. Homeowners should expect perimeter trenching, concrete removal, drain installation, and patch-back along the basement edge.
What warranty does Groundworks offer?
Groundworks says its waterproofing work is backed by a nationally backed warranty through its company network. Exact terms can vary by project and agreement, so homeowners should confirm what is covered in writing before signing.
