Commercial Exterior Drainage Services
Commercial exterior drainage systems play a critical role in protecting buildings and surrounding areas from water damage. These systems are designed to collect, channel, and safely discharge rainwater and stormwater runoff, preventing flooding, erosion, and other water-related issues. Effective drainage is essential for maintaining the structural integrity of buildings, preserving landscaping, and ensuring safety for occupants and visitors.

Key Components of Commercial Exterior Drainage Systems
- Gutters and Downspouts: Gutters are installed along roof edges to collect rainwater, which is then channelled through downspouts to discharge points.
- Storm Drains: Storm drains are underground pipes that collect and transport stormwater runoff to a discharge point, such as a river, lake, or storm sewer.
- Catch Basins: Catch basins are located at the entrance to storm drains to capture debris and sediment before they enter the pipes.
- Storm Sewer Systems: Storm sewer systems are networks of pipes that connect catch basins, and storm drains to larger discharge points.
- Retention Ponds and Detention Ponds:These structures are used to capture and temporarily store stormwater runoff, allowing it to infiltrate into the ground or evaporate.

Benefits of Effective Commercial Exterior Drainage
- Flood Prevention: Well-designed drainage systems can help prevent flooding, which can cause significant property damage and disrupt business operations.
- Erosion Control: Proper drainage can prevent erosion of the surrounding landscape, protecting buildings and infrastructure from damage.
- Water Quality Protection: By managing stormwater runoff, drainage systems can help prevent pollution of local waterways.
- Safety and Comfort: Effective drainage can improve safety by reducing the risk of slips, trips, and falls caused by standing water. It can also enhance comfort by preventing water from pooling around buildings and creating a damp environment.

Factors to Consider in Commercial Exterior Drainage Design
- Site Conditions:The topography, soil type, and climate of the site will influence the design of the drainage system.
- Building Type:The type and size of the building will determine the amount of stormwater runoff that needs to be managed.
- Local Regulations:Compliance with local building codes and regulations is essential for ensuring the safety and effectiveness of the drainage system.
- Maintenance Requirements:The chosen drainage system should be easy to maintain and inspect to ensure its long-term performance.
