Drainage Installation & Repair in King of Prussia, PA
Move Water Away Before It Reaches Your Foundation or Pavement
One inch of rain falling on a 1,000 square foot roof produces roughly 623 gallons of water, and all of it has to go somewhere. Richard Cooper's All Around Asphalt provides drainage installation and repair in King of Prussia, PA, including French drains, buried downspout lines, catch basins, trench drains, and underground pipe repair. We protect homes and pavement for property owners in Sinking Spring, Reading, Norristown, and West Chester from standing water and erosion.
Across 16+ years around driveways and grading, we have learned that water is behind most pavement failures and many wet basements. We trace where runoff actually flows, then design drainage that works with the slope of your property instead of against it. Installations use proper pipe fall, clean stone, and fabric where needed, and damaged lines are repaired or upgraded to handle heavier storms.

Drainage Systems We Install and Repair
French Drain Installation
A trench lined with filter fabric holds perforated pipe surrounded by clean stone, collecting groundwater and surface runoff before it reaches problem areas. The pipe carries water to a safe outlet, drying out soggy yards and relieving pressure against foundations.
Downspout and Underground Piping
Gutters dumping water beside the foundation undo the purpose of the gutter system. Downspouts are connected to buried solid pipe that carries roof runoff well away from the house to a daylight outlet, dry well, or approved discharge point.
Catch Basin and Yard Drain Installation
Low spots that collect water get a catch basin or yard drain set at the lowest point. Surface water enters the grate, and connected piping carries it away, eliminating puddles that damage lawns, attract mosquitoes, and freeze into winter hazards.
Trench Drains at Driveways
Driveways that slope toward garages or walkways often send water where it does not belong. A channel drain set across the pavement intercepts runoff before it reaches the door, directing it into underground pipe and keeping entrances dry year round.
Drain Line Repair and Replacement
Crushed, clogged, or disconnected pipes stop moving water and can create hidden saturation underground. Failed sections are located, excavated, and replaced with new pipe at the correct slope, restoring flow and preventing further damage to pavement and foundations.
Drainage System Upgrades
Older systems built with undersized or corrugated pipe often fall short during heavy storms. Upgrading capacity, adding inlets, or rerouting lines brings aging drainage up to the demands of modern rainfall and any new pavement added to the property.
Why Choose Us for Drainage Installation & Repair
Guessing at drainage leads to systems that miss the real problem. Watching how runoff travels across your property, and identifying where it collects, allows the design to target the actual source rather than just the spot where damage appears.
Solutions Based on How Water Really Moves
A drain pipe without enough slope holds water, collects sediment, and eventually clogs. Setting consistent fall along every line keeps water moving to the outlet, so the system keeps working through years of storms without constant maintenance or repeated digging.
Correct Pipe Fall on Every Run
Water problems and pavement problems are usually connected. Because the same crew handles grading, drainage, and asphalt, solutions account for how new surfaces will shed water, preventing the common mistake of paving a driveway that sends runoff somewhere worse.
Drainage and Pavement Planned Together
Soil washing into a drain slowly chokes it. Using clean stone and filter fabric where appropriate keeps fine particles out of the pipe, which extends the working life of your system and protects the money you put into it.
Materials That Resist Clogging
Drainage work involves digging, but it does not need to wreck your landscape. Trenches are planned along efficient routes, soil is managed carefully during the job, and disturbed areas are restored neatly so your yard recovers quickly afterward.
Minimal Disturbance to Your Yard
Standing water softens the ground under driveways and pushes moisture toward basement walls. Moving that water away protects two of your biggest property investments at once, reducing the risk of cracked pavement, wet basements, and costly structural repairs.
Protection for Foundations and Pavement
Frequently Asked Questions
How does a French drain work?
A French drain gives water an easier path than the surrounding soil. Groundwater and runoff seep into a gravel-filled trench, enter perforated pipe, and flow downhill to an outlet. Filter fabric keeps soil out so the system does not clog.
Where should downspouts discharge?
Downspouts should release water well away from the foundation, ideally through buried pipe to a daylight outlet, dry well, or other approved location. Water should never discharge onto a neighbor's property or toward pavement where it can undermine the base.
Why is water pooling at the end of my driveway?
Pooling usually means the driveway was paved without enough slope, the ground beside it sits higher than the pavement, or runoff from the street has nowhere to go. A trench drain, regrading, or a catch basin typically solves the problem.
What are the signs of a failing underground drain line?
Watch for water backing up out of downspouts during storms, soggy spots above buried pipe, sinkholes, or erosion near the outlet. Any of these suggests a crushed, clogged, or disconnected section that needs locating and repair before damage spreads further.
How deep should a French drain be?
Most French drains are dug 18 to 24 inches deep, though depth varies with the problem being solved. Richard Cooper's All Around Asphalt sets trench depth and pipe fall for King of Prussia, PA properties based on soil and slope.
Can drainage be added to an existing driveway?
Yes. A trench drain can be cut across the pavement and connected to underground pipe, or drains can be installed along the edges to capture runoff. Adding drainage saves a driveway that would otherwise crack and settle from water damage.
Does Upper Merion Township charge a stormwater fee?
Properties in the township with at least 500 square feet of impervious surface pay a stormwater fee. Richard Cooper's All Around Asphalt uses 16+ years of drainage experience to help King of Prussia, PA owners manage runoff on their properties.
Does a trench drain need maintenance?
Clearing the grate and channel of leaves, grit, and debris a few times a year keeps a trench drain working properly, especially after fall. Flushing the line with a hose occasionally confirms water is still flowing freely to the outlet.
Dry Ground, Stronger Pavement, Fewer Worries
Water left to wander will eventually find your foundation, soften your driveway base, or turn part of your yard into a swamp.

There is no need to decide right away, and we are happy to walk the site with you and explain what is causing the problem.
