Family-owned since 1999, DrainMaster diagnoses the problem, explains your options and gets your approval before any storm drainage repair work begins.
Are your downspout lines backing up at the foundation wall, or are yard catch basins holding stagnant water after rain moves through your Westerville property? When underground storm lines choke or collapse, large volumes of roof runoff cannot escape to the street, saturating the ground and pushing water straight against basement walls and crawl spaces. DrainMaster provides targeted diagnostics, utility excavation, and storm drainage repair throughout the area to protect your property from structural moisture damage.
Recognizing the early symptoms of a failing exterior drainage system helps prevent structural water intrusion. Subsurface storm pipes carry immense volumes of water away from structures, and even a partial line compromise will show symptoms across your lawn and along your foundation.
The following signs indicate that your underground storm drainage system requires professional attention:
Downspout cleanouts and underground adapters often overflow at the base of the home during steady rainfall, spilling roof runoff directly against foundation footers. This spillover indicates an obstruction, separation, or structural collapse in the buried lateral line running between the foundation and the street discharge. Water entering the backfill zone right next to the foundation creates hydrostatic pressure that bows basement walls and produces persistent interior seepage.
Low areas across your yard or designated drainage swales should clear standing water once rainfall stops. When depressions hold standing water, the buried French drain lines or perforated collector pipes have likely silted shut, lost their pitch, or crushed under the weight of the soil. Saturated yard bogs kill healthy turf grass and weaken the soil stability supporting nearby walkways, patios, and driveways.
A basement sump pump should shut off shortly after active water infiltration around the footing drains subsides. If your pump cycles continuously or you observe discharge water bubbling backward out of the exterior cleanout, the dedicated storm lateral leading away from the house is compromised. An obstructed discharge pipe forces the pump to work against severe backpressure, leading to premature mechanical failure and leaving your basement vulnerable to sudden flooding.
Surface catch basins should draw water off low-lying lawn areas, driveways, and parking pads. When these basins remain full of murky water, decaying leaves, and heavy silt, the outlet pipe downstream has usually settled, sheared off, or become clogged with wash-off debris. Backed-up catch basins allow unmanaged surface water to find the path of least resistance, which often leads directly toward basement window wells or adjacent properties.
Exterior drainage pipes exist in a harsh subterranean environment subject to soil movement, mechanical loading, and biological intrusion. Identifying the underlying mechanism behind a drainage failure helps ensure that repairs resolve the underlying site conditions rather than simply treating an isolated symptom.
Older drainage systems often feature thin-wall flexible corrugated plastic pipe installed to carry storm runoff away from foundations. This lightweight black tubing frequently crushes under soil compaction, heavy mowing machinery, or vehicle traffic over driveway edges. We resolve this vulnerability by removing the deformed tubing and installing rigid, heavy-duty pipe that maintains its structural integrity and ensures smooth gravity flow.
The ground can expand when holding moisture and contract during dry periods. This continuous underground movement causes shallow drainage lines to shift, heave, and lose their downward grade over time. When a pipe develops low spots or back-pitches toward the house, water stands still and drops its sediment load, creating persistent blockages that we correct by re-establishing proper fall with utility excavation.
Trees send aggressive feeder roots deep into the ground searching for continuous moisture, air, and dissolved nutrients. Fine root hairs penetrate pipe seams, push through degraded joint connections, and exploit hairline fractures in aging clay tiles or brittle plastic lines. Once inside, the roots expand into massive fibrous mats that trap leaves and roof gravel, requiring specialized clearing or targeted pipe repair to restore proper water flow.
Roof runoff carries far more than just clean rainwater into your underground drainage network. Asphalt shingle granules, decaying leaves, twigs, and fine surface grit steadily wash into downspout lines, gradually accumulating along the bottom of lines with low slope or corrugated interiors. Over time, these materials form a solid, cemented plug that cannot be cleared by natural water pressure, requiring high-pressure flushing and the addition of proper cleanouts.
When a technician arrives at your property, we begin by tracing the complete path of your exterior drainage network, from roof downspout boots and surface grates to the final discharge point. We run water through individual runs to test flow rates, observe where water backs up, and determine which segments are failing to convey volume. Where pipe conditions and access points allow, we perform a sewer camera inspection inside the storm line to view the interior condition, locate root masses, identify crushed sections, and pinpoint the exact depth and location of underground issues.
After inspecting the lines, we explain our findings in plain language and provide clear repair options tailored to your property. DrainMaster uses dedicated excavation machinery operated by experienced crews who understand how to work carefully around existing utilities and landscape features. If the line requires physical replacement, our team strips the turf cleanly, hand-digs near sensitive underground lines, and grades the new trench to restore positive downward pitch.
We install durable, smooth-wall rigid pipe, bed the new line properly in gravel, and perform a volume flow test before closing the trench. Our crew backfills the excavation in lifts, compacting the soil to minimize future settlement, and neatly rakes the work area so your lawn can recover.
Underground storm lines often share yard pathways with sanitary lines and rely heavily on indoor pumping equipment to keep properties dry. If your storm pipes are mechanically sound but clogged with compacted silt and roof granules, our team utilizes commercial hydro jetting equipment to scrub the interior walls clean with high-pressure water. In addition, exterior storm performance is directly tied to your interior basement safety, making sump pump repair and replacement an essential consideration if your pump has suffered wear while pushing water into an obstructed storm lateral.
Postponing exterior drainage repairs allows large volumes of roof and surface runoff to concentrate around your foundation during every weather event. This water creates severe hydrostatic pressure against exterior basement walls, forcing moisture through porous concrete block, opening mortar joints, and promoting persistent mold growth inside your living spaces. Saturated subsoils also lose their load-bearing capacity, which can cause foundation footers to settle unevenly and lead to cracked interior drywall, sticking doors, and fractured basement slabs.
Unmanaged surface water also ruins exterior hardscaping and landscape investments. Water that bypasses failed drainage pipes washes away supporting subgrade materials beneath concrete driveways, stone patios, and front walkways, resulting in dropped slabs, uneven surfaces, and damaged concrete. Addressing an underground storm drainage failure early with targeted pipe work helps prevent the need for extensive interior foundation waterproofing, structural underpinning, and complete yard restoration later.
