Common solutions for Tompkinsville properties

Downspout Diversion

Redirects roof runoff away from the combined sewer and into landscaped or permeable areas on the lot.

Infiltration System

Drywells or infiltration chambers that let stormwater soak into the ground on-site instead of entering the sewer.

Detention System

Holds stormwater temporarily and releases it slowly, reducing peak flow into the combined sewer during a storm.

Drain Improvement

Upgrades yard, area, or foundation drains so water is carried away from the building instead of pooling.

Foundation Waterproofing

Protects the foundation from groundwater intrusion, relevant where groundwater exposure runs high.
