Basement Waterproofing Photo Album: Waterproofing a Partially Finished Basement in Seabrook, NH

Facing water leaks through the bulkhead and cold joints, this Seabrook, NH homeowner turned to us for a permanent fix, ensuring a safe basement for their grandchildren. Notice in the before photo the risk of water damage to the basement bedroom. We expertly installed the WaterGuard system, TripleSafe Sump Pump, and IceGuard technology. As you can see in the after photo, our solution provides a dry, healthy space—perfect for creating a welcoming environment for family gatherings.

Basement Floor Water Seepage

Water intrusion occurred throughout multiple areas of the basement, rendering the space uninhabitable. Persistent leakage has placed stored belongings at ongoing risk and has contributed to conditions conducive to mold growth, efflorescence, and other moisture‑related health concerns.

Protecting Basement Items

All stored belongings in the basement were carefully protected to prevent dust exposure and ensure their safety throughout the installation process.

WaterGuard Drainage

The perimeter section of the basement slab was excavated to create the necessary channel for installing the WaterGuard® perimeter drainage system. Positioned above the home's footing, WaterGuard® intercepts groundwater seepage before it can enter the basement interior. Collected water is then directed through the drainage system and discharged via the sump pump for effective removal.

Drainage System Connected to Sump Pump

The WaterGuard® drainage system integrates directly with the sump pump system, channeling collected water efficiently into the sump liner for controlled removal.

Basement Surface Drainage

A TrenchDrain system was installed to divert surface water around immovable basement utilities. The TrenchDrain integrates directly with the WaterGuard® perimeter drainage system, creating a continuous, unified pathway that directs all collected water toward the sump pump for efficient discharge.

TripleSafe Sump Pump

The TripleSafe® Sump Pump System incorporates three independently functioning pumps-a primary pump, a secondary high‑capacity pump, and a battery‑operated backup unit. This multi‑pump configuration provides redundant protection and ensures continuous, reliable water removal, even in the event of heavy water intrusion or a power outage.

Discharge Line Freeze Failsafe

An IceGuard® anti‑freeze discharge line attachment was installed to ensure that water can safely exit the home even if the exterior discharge line freezes or becomes obstructed. This failsafe mechanism prevents system backups that could otherwise result in basement flooding.

Bubbler Pot

A bubbler pot was installed at the termination point of the discharge line to allow water to disperse efficiently into the surrounding soil. This design minimizes surface saturation, preventing soggy lawn conditions and water pooling. The discharge line was then buried to maintain yard aesthetics and protect the system's long‑term functionality.
