Exterior Site Drainage for Commercial Properties Across the CT Shoreline
Drainage Pro of CT works with commercial property owners, property managers, and facilities directors across the Connecticut Shoreline. Every service we provide is focused on water that is on your site, moving across it, pooling on it, or pressing against your building from the outside. We do not work inside buildings. We solve site drainage problems on the exterior, which is where they start.
If water is pooling in your parking lot after every rainstorm, collecting at your loading dock, saturating the ground around your building perimeter, flooding your access roads, or creating stormwater compliance issues on your site, we are the exterior drainage contractor you need to call. We bring the same drainage-first approach to commercial sitework that we apply to every property we serve, scaled to the footprint, volume, and regulatory requirements that commercial properties demand.
We are based in Clinton and serve commercial properties from East Haven and Branford in the west to East Lyme and Old Lyme in the east, and inland through Killingworth, North Branford, and Durham. Our 13-town service area covers the Route 1 commercial corridor, the industrial areas of East Haven and Branford, the waterfront commercial properties of Old Saybrook and Essex, and the mixed-use and institutional properties found throughout every town we serve.
Commercial Exterior Drainage Services We Provide
Every service below is exterior site drainage work. We manage water on your property, on the surface, below grade, and at the perimeter of your building. The line we hold is straightforward: water leaving the property, not water inside the building. If your drainage problem starts outside, we solve it.
Large-scale commercial properties and industrial sites require perimeter drainage systems that go well beyond a residential French drain in scope and capacity. We design and install exterior French drain systems sized to the water volume your site generates, using commercial grade perforated pipe, drainage stone, and filter fabric appropriate for larger building footprints, heavier soil loads, and higher ground pressure conditions. We install exterior French drain systems for warehouse perimeters, office complexes, institutional campuses, and industrial facilities throughout our service area.
Commercial buildings sit on larger footprints with more perimeter wall exposed to saturated soil and hydrostatic pressure than residential properties. We install exterior foundation drainage systems using waterproofing membrane applications, drainage boards, and footing drain pipe that intercepts groundwater on the outside of the building and routes it away from the structure entirely. This is exterior sitework. We address the water source on the outside of your building before it becomes a problem inside.
Catch basins are a core component of commercial site drainage systems. They collect surface water from paved areas, loading zones, open lots, and low points in your site and route it into an underground pipe network that discharges safely to a compliant outlet. We install new catch basins sized to the surface area and runoff volume they need to manage, and we maintain existing catch basin systems for commercial properties across the Connecticut Shoreline. Regular catch basin maintenance prevents sediment buildup that reduces capacity and causes overflow during storm events.
Some commercial sites require retention or detention basin systems as part of a stormwater management plan or as a condition of local or state permitting. A retention basin holds stormwater on site permanently and allows gradual percolation. A detention basin holds stormwater temporarily during a storm event and releases it slowly to reduce peak discharge rates to the receiving system. We design and install exterior retention and detention basin systems for commercial properties across Middlesex, New Haven, and New London counties, sized and graded to meet the performance requirements your site and your municipality demand.
Commercial properties on the Connecticut Shoreline are subject to stormwater management requirements that residential properties are not. If your site needs a drainage solution that meets Connecticut DEEP requirements, local land use conditions, or municipal stormwater ordinances, we design and install exterior stormwater management systems that address both the practical drainage problem and the regulatory requirement. We work with property owners and facilities managers to document the system, understand the maintenance obligations, and make sure the exterior drainage infrastructure on your site is built to the standard required.
A commercial parking lot that floods after every rainstorm is a liability issue and a customer experience problem. An access road with standing water accelerates pavement deterioration and creates safety hazards for vehicles and pedestrians. We install exterior drainage systems for commercial parking lots and access roads, including trench drain systems that intercept surface water sheeting across paved areas and route it to storm discharge, and catch basin networks that collect water at low points before it pools. We serve commercial properties along the Route 1 corridor from Westbrook through Old Saybrook, the denser commercial areas of Branford and East Haven, and commercial and institutional properties throughout all 13 towns in our service area.
When water is flowing onto your commercial site from an adjacent slope, an uphill neighboring property, or a higher section of your own land, a curtain drain positioned across that flow path intercepts the water before it reaches the area causing you trouble. We install commercial curtain drain systems sized and sloped to handle the volumes that larger properties and paved surface concentrations generate. Curtain drains are a standard component of exterior site drainage solutions for commercial properties with challenging topography or significant offsite water contribution.
Loading docks concentrate roof leader discharge, vehicle wash-down water, and general precipitation into an area that needs to drain quickly and stay clear for operations. Water pooling at a loading dock creates safety hazards, accelerates concrete and pavement deterioration, and interrupts day-to-day logistics. We install exterior drainage systems at loading dock areas including trench drains and area drains that collect water at the dock level and route it away from the structure and off the property through a compliant discharge outlet.
Commercial buildings have significantly larger roof areas and more roof leaders than residential properties, which means the volume of water discharging at grade is proportionally higher. If your roof leaders are discharging against the building foundation or into areas of your site that cannot manage the volume, you are concentrating a drainage problem at the base of your building with every rain event. We install underground pipe extensions from commercial roof leaders and downspouts that carry water away from the building perimeter and route it to a compliant exterior discharge point.
The surface grade of your commercial site controls where water goes when it rains. A site graded toward the building, toward a neighboring property, or into areas that concentrate rather than disperse water is a site with a drainage problem that worsens with every storm season. We regrade commercial sites and construct swales that direct surface water away from buildings, parking areas, and access roads and toward appropriate discharge points. We approach every commercial grading project with a full understanding of how water moves across the entire site, not just the zone directly in front of us.
Open yard areas, green spaces, and unpaved sections of commercial properties collect surface water just as effectively as paved surfaces, and without the drainage infrastructure to move it. We install yard drains and area drains sized for commercial runoff volumes, connected to discharge systems that route water to daylight, to a dry well, or to the municipal storm system depending on your site's location, soil conditions, and applicable permitting requirements. We handle exterior area drain installation for commercial properties throughout our service area, from smaller business lots in Essex and Westbrook to larger commercial and industrial parcels in Branford, East Haven, and Old Saybrook.
Who We Work With on Commercial Drainage Projects
Our commercial drainage clients across the Connecticut Shoreline include a range of property types and the people responsible for managing them. Here are the situations we work in most frequently.
Property Managers and Facilities Directors
If you manage a commercial property portfolio or oversee the physical operations of a building or campus on the Connecticut Shoreline, exterior drainage problems are the kind of issue that creates liability exposure, tenant complaints, and deferred maintenance costs when they go unaddressed. We work directly with property managers and facilities directors to assess site drainage conditions, recommend the right exterior solutions, and complete installations with minimal disruption to ongoing operations. We provide documentation of the work completed and can coordinate with your maintenance team on any ongoing system requirements.
Building Owners and Developers
If you own commercial real estate on the Connecticut Shoreline and water is affecting the condition of your site, the safety of your tenants, or your ability to meet stormwater compliance requirements, we provide the exterior drainage expertise to address it. We work with building owners on individual property drainage corrections and with developers on site drainage systems for new construction and redevelopment projects where exterior water management needs to be designed and installed as part of the overall sitework.
Industrial and Warehouse Operators
Industrial sites and warehouse facilities generate high volumes of stormwater from large roof areas, extensive paved surfaces, and loading and staging areas. Exterior site drainage failures at industrial properties create operational disruptions, safety hazards, and potential compliance issues. We install exterior French drain perimeter systems, catch basin networks, trench drain systems at loading and staging areas, and complete stormwater management infrastructure for industrial properties throughout the Connecticut Shoreline, including the industrial corridors of East Haven and Branford.
Retail, Hospitality, and Institutional Properties
Retail centers, hotels, medical facilities, schools, and municipal properties across the Connecticut Shoreline all share the same exterior drainage challenges: parking lots that flood, access roads that pool, building perimeters that accumulate water, and stormwater obligations that require documented management systems. We serve all of these property types with the same exterior drainage approach, sized and designed to the specific requirements of each site.
Why Commercial Property Managers Choose Drainage Pro of CT
There is no shortage of contractors on the Connecticut Shoreline willing to take on a commercial drainage job. What is rare is a contractor who treats commercial site drainage as a specialty rather than an occasional add-on to their regular workload. Here is what makes working with us different.
We Work Exclusively on the Exterior
Everything we do is exterior site drainage. We do not cross into building systems, interior work, or utility infrastructure. That clear scope is what makes us a reliable partner for property managers and facilities directors who need exterior drainage resolved without a contractor overreaching into systems that require different licensing, different coordination, and different accountability. Our lane is exterior water management, and we stay in it.
We Diagnose Before We Recommend
Commercial drainage problems are rarely as simple as they appear on the surface. A parking lot that floods may be a grading issue, a blocked catch basin, an undersized pipe network, or a combination of all three. We assess the full exterior drainage picture on your site before recommending a scope of work, because the right solution depends on understanding the actual cause, not just treating the visible symptom.
We Size Systems for Real Conditions
Commercial sites generate higher runoff volumes than residential properties, and Connecticut's storm patterns deliver that volume at intensities that generic sizing guidelines do not account for. We design exterior drainage systems for your site's actual conditions, actual soil type, actual surface area, and actual storm exposure. An undersized system fails during exactly the events you installed it to handle.
We Back Every Installation with a 5-Year Warranty
Every commercial drainage installation we complete is backed by our 5-year workmanship warranty on the mechanical flow and function of the system. For property managers and building owners who need documented assurance that the drainage investment will perform as designed, our warranty provides that coverage from the day we complete the installation.

Frequently Asked Questions About Commercial Drainage Services
What types of commercial properties do you work on?
We work on any commercial property where exterior site drainage is the issue. This includes retail centers, office buildings, warehouses, industrial facilities, hotels, medical buildings, schools, municipal properties, and mixed-use developments. The common thread is that the drainage problem is on the exterior of the site, on the surface, below grade, or at the building perimeter. We do not work on interior building systems of any kind.
Do you handle stormwater compliance documentation?
We work with commercial property owners and facilities managers to make sure exterior drainage systems are built to the standard required by local municipalities and Connecticut DEEP where applicable. We can provide documentation of the work completed and help you understand the maintenance requirements of the system. For complex permitting situations, we recommend coordinating with a licensed civil engineer who can provide stamped documents for regulatory submissions.
Can you work around active commercial operations?
Yes. We schedule commercial drainage work with your operational requirements in mind and coordinate directly with your facilities team or property manager on access, phasing, and timing. We have worked around active retail operations, warehouse logistics schedules, and tenant-occupied buildings across the Connecticut Shoreline and we approach every commercial project with the understanding that disruption to your operations has a direct cost.
How is commercial drainage pricing different from residential?
Commercial drainage projects are scoped and priced based on the size of the system, the volume of water it needs to manage, soil conditions, site access, and the complexity of the discharge and compliance requirements involved. There is no single price range that covers commercial work the way there is for a standard residential French drain or downspout extension. We provide free on-site assessments for commercial properties and deliver detailed estimates with itemized pricing before any work begins.
