About French Drains and Sump Pumps

What Are French Drains?

A French drain is a sloped trench with a perforated pipe surrounded by gravel, designed to redirect groundwater away from your foundation. It passively prevents water seepage into your basement, ideal for NJ's wet climate (45" annual rainfall).

How They Work

Collects groundwater through a perforated pipe in a gravel-filled trench, channeling it away from the foundation by a sump pump, relieving hydrostatic pressure.

What Are Sump Pumps?

A sump pump is an electric device in a basement pit that actively removes water collected from French drains or floor seepage, pumping it away from your home via a discharge line.

How They Work

Installed in a pit at the basement’s lowest point, they activate when water levels rise, pumping water out through a discharge line away from your home.

Proper Installation of
French Drains and Sump Pumps

Our systems are installed the right way to protect your home for the long haul.

French drains are installed along the inside edge of the basement to collect and redirect groundwater before it reaches your floor.

Weep holes are added in concrete block walls to relieve water pressure and prevent wall seepage.

A perforated pipe, surrounded by drainage stone and wrapped in fabric, directs water to a sump pump.

The system is sealed with fresh concrete for a clean, finished look.

A sump pump is installed at the lowest point of the basement to automatically pump water out.

Discharge lines are extended far from the home to prevent water from recycling back toward the foundation.

Professional installation ensures your system is reliable, code-compliant, and built to last.

Why Professional Installation Matters

  • Prevents foundation damage, mold, and future repairs

  • Ensures full compliance with NJ building codes

  • Avoids shortcuts like unsealed pits or wrong pipe placement

  • Custom solutions for finished basements and monolithic slabs
