Plymouth Drainage Services

Reliable Drainage for Businesses, Contractors, and Property Managers

Water damage on commercial properties doesn’t just cause aesthetic issues—it can threaten structural integrity, reduce usability, and result in costly downtime. Diversified Drainage offers scalable, code-compliant systems for commercial buildings, industrial sites, and multifamily developments.

We handle commercial drainage projects such as: 

• Stormwater retention & detention systems – Controls runoff on large sites by capturing water during storms and releasing it slowly to reduce downstream impact and meet local code requirements.

• Parking lot drainage and trench drains – Prevents pooling, ice formation, and long-term pavement damage by directing water away from high-traffic areas quickly and safely.

• Drain tile installation for building perimeters – Protects foundations and lower levels from water infiltration by channeling subsurface moisture away from structures.

• Crawl space and basement waterproofing – Combines drainage improvements with sealants and sump systems to create dry, mold-resistant environments in commercial basements and storage spaces.

• Grading and earthwork for site development – Ensures surface water flows away from structures and sensitive areas by shaping the land during the early stages of construction or retrofits.

• Surface water redirection for sidewalks, entries, and landscaped areas – Improves pedestrian safety and protects exterior finishes by guiding rainwater away from building entries and common spaces.

• Emergency drainage corrections for active leak or flooding issues – Rapid-response services to address drainage failures, blockages, or stormwater overloads before they escalate into major property damage.

We collaborate with general contractors, architects, landscape designers, and facility managers to ensure every system is built to perform—and built to last.

Protect Your Yard, Basement, and Foundation

Poor drainage can turn a beautiful yard into a soggy mess and lead to costly structural problems in your home. Our residential drainage services are designed to redirect water safely and efficiently—without compromising the look of your landscape.

Homeowners trust us for:

• French drains & drain tile systems – Subsurface solutions that carry water away from foundations and low spots.

• Downspout drainage extensions – Keeps roof runoff from pooling near your home.

• Grading & re-sloping – Adjusts the terrain to promote healthy surface water flow.

• Sump pump discharge routing – Prevents your system from draining directly back toward the house.

• Basement and crawl space drainage – Stops leaks at their source and protects against long-term water damage.

• Dry wells & infiltration systems – Manages stormwater onsite without harming your landscape.

• Berms and swales – Natural-looking solutions to redirect water on the surface.

• Landscape drainage corrections – Integrates with gardens, lawns, and patios.

We work with both existing landscapes and new construction, and always take a clean, minimally invasive approach to every residential install.

Serving Public Works, Parks, Schools, and Local Agencies

Municipal drainage requires a higher level of planning, coordination, and accountability. Our team is experienced in supporting public infrastructure projects throughout the Twin Cities metro area, including drainage systems for roads, parks, schools, and city buildings.

Municipal services include:

• Storm sewer tie-ins and extensions – Integrates new or upgraded drainage systems into existing municipal stormwater infrastructure, ensuring proper flow and regulatory compliance.

• Culverts and ditch improvements – Enhances water movement beneath roads, trails, and driveways while reducing erosion and improving public safety.

• Street and curb drainage grading – Shapes roadbeds and curb lines to efficiently direct runoff into storm inlets and away from travel lanes and pedestrian areas.

• Athletic field and park drainage systems – Installs subsurface and surface systems that keep recreational fields, walking paths, and green spaces usable and safe after rainfall.

• Public trail and right-of-way improvements – Addresses drainage concerns along public paths, sidewalks, and utility corridors, helping cities maintain accessibility and prevent long-term damage.

• Swale construction and vegetative buffers – Creates eco-friendly surface drainage solutions that filter runoff, slow erosion, and enhance the surrounding environment.

We understand the timelines, permitting, and community expectations that come with public projects. Our crew is respectful, efficient, and committed to safety and compliance from start to finish.
