Redirect Water Before It Reaches Your Foundation

French drain installation and maintenance in Norristown manage surface and subsurface water before it causes problems.

When rain collects in your yard or saturates the soil near your foundation in Norristown, it creates pressure that pushes water toward your basement walls. You might notice soggy patches that do not dry out, water pooling near the foundation after storms, or damp spots inside your basement that seem to appear without warning. Tru Basement Waterproofing, Inc. installs French drain systems that intercept water before it reaches your foundation, redirecting it to a safer discharge point away from your home. Norristown soil and rainfall conditions make French drains one of the most effective long-term solutions for recurring water problems, especially in yards that slope toward the house or have clay-heavy soil that drains slowly.

A French drain is a gravel-filled trench with a perforated pipe at the bottom, buried along the perimeter of your foundation or across areas where water collects. Water flows into the pipe through the perforations and travels along the trench to a discharge point, often a storm drain or low area away from your home. Maintenance services include flushing the pipe to remove sediment buildup, checking discharge points, and ensuring the system continues to drain properly as soil shifts over time.

How the system intercepts and moves water

Installation begins with excavating a trench along the foundation or across the yard where water accumulates. In Norristown, trenches are typically sloped to guide water toward a discharge point, and the depth depends on the water table and soil conditions. A perforated pipe is laid at the bottom, covered with gravel to allow water to filter in, and then topped with soil or sod to restore the surface.

After installation, water no longer pools near your foundation or saturates the soil around your basement walls. Rain is intercepted underground and carried away before it can create pressure or seep through cracks. Your yard dries faster, and your basement stays drier even during extended wet periods.

Maintenance includes inspecting the discharge point to confirm water is exiting properly, flushing the pipe to clear any sediment or root intrusion, and checking the trench for settling or erosion. Pennsylvania soil can shift with freeze-thaw cycles, and regular maintenance keeps the system functioning as intended. French drains work best when paired with downspout extensions and grading adjustments that direct water away from the foundation at the surface level.

Most homeowners have similar questions at this stage

Homeowners in Norristown often ask about placement, maintenance frequency, and how long the system lasts, so here are answers to the most common concerns that come up before installation.

Where should a French drain be installed?
It should be installed where water collects or flows toward your foundation. This is often along the perimeter of your basement walls or across low spots in your yard where water pools after storms.
How often does a French drain need maintenance?
You should have it inspected and flushed every three to five years, or sooner if you notice slower drainage or water pooling where it used to flow freely. Sediment and root growth can reduce flow over time.
What is the difference between an interior and exterior French drain?
An exterior French drain is installed outside your foundation to intercept water before it reaches the walls. An interior French drain is installed inside the basement along the perimeter to collect water that has already entered and direct it to a sump pump.
How long does a French drain system last?
A properly installed and maintained French drain can last 20 to 30 years. Lifespan depends on soil conditions, maintenance frequency, and whether the discharge point remains clear.
Why does my yard still get soggy after a French drain was installed?
The drain may be clogged, the discharge point may be blocked, or the system may not be sized or positioned to handle the volume of water your yard receives. An inspection in Norristown will identify the issue.
