Basement Waterproofing in Mount Holly, NJ

When the Rancocas rises

The North Branch of the Rancocas Creek floods parts of Mount Holly in heavy rain. National Weather Service gauge information for the creek at Mount Holly lists flooding beginning near 11.7 feet, with water over the Mill Dam and streets such as Washington Street, Park Drive, Trinity Lane and Commerce Street flooding around 13 feet; the record crest was about 14.3 feet in June 2019. Basements near the creek can take on water both from surface flooding and from groundwater that rises with the creek.

• A waterproofing system can manage groundwater seepage, but no basement system holds back a creek in flood. Flood insurance and keeping utilities off the floor matter here.
• Check your address on FEMA's Flood Map Service Center, and ask the township about any rules for work in flood hazard areas.
• After a flood, stay out of water near electricity, photograph damage, and call your insurer before cleanup.

Historic cellars

Mount Holly's historic district along High Street, Mill Street, Pine Street and Garden Street has many older homes with stone and brick foundations. These walls let moisture through mortar joints, and sealing them with the wrong products can trap water and damage the masonry. Interior drainage to a sump, careful mortar repair and dehumidification are common approaches. On tight in-town lots, exterior excavation is often impractical.

Sewer backups

In heavy storms, some basements take on water through floor drains instead of the walls. That is often a sewer backup, which is a plumbing problem. A licensed plumber can assess a backwater valve, which generally requires a plumbing permit in New Jersey.

Sump discharge in town

Sending sump water into the sanitary sewer is generally prohibited by sewer utilities. On small lots, finding a safe outlet away from the house and neighbors takes some planning; ask the contractor.

Covering all of Mount Holly

Requests come in from the historic district and the blocks around Mill Dam Park and Iron Works Park, and from streets along High Street, Mill Street, Washington Street, Garden Street, Pine Street and the Route 541 bypass (ZIP 08060). The Mount Holly Township area sits near the North Branch of the Rancocas Creek, so mention in your request if your property is low-lying or close to the water.
