Basement & Foundation Drainage Systems | Keep Water Out
"*" indicates required fields
When it comes to protecting your property, a drainage system is one of the most important investments you can make. At Premium Technical Services, we design, install, and maintain advanced basement drainage systems and exterior solutions that safeguard your structure, prevent erosion, and stabilize surrounding soil.
Serving Nassau County, Suffolk County, and the Greater NYC area, where humid summers, heavy storm flooding, and older housing stock create persistent water challenges, our team delivers customized building protection for residential, commercial, and distribution properties.
Whether you need interior basement drains, French drains, or pipes for a commercial-grade installation, Premium Technical Services provides complete solutions that keep water moving away from your foundation. From damp Long Island basements and flooded NYC crawl spaces to large office complexes and regional warehouses, our systems stop water intrusion before it causes costly foundation damage or long-term structural problems.Â
We also support contractors across the Northeast through Foundation Supply, completing projects in Pennsylvania, New Jersey, Maine, New Hampshire, and beyond with quality materials and technical expertise.
By combining expert design with durable, long-lasting materials, Premium Technical Services ensures that every drainage system functions as a long-term defense against soil saturation, building settlement, and basement leaks.
Why Proper Drainage Is Essential for Property Protection
A well-designed system is the first line of defense against costly water problems. In regions like Nassau County, Suffolk County, and Greater NYC, where steep slopes and heavy rainstorms are common, directing water away from your home or business is essential. Without an effective drainage system, even a short burst of rain can lead to foundation cracks and flooded basements.
Premium Technical Services combines solutions like sump pumps, French drain installation, and interior drainage system design to keep moisture under control. These systems prevent standing water that can weaken foundations, reduce surface drainage issues, and stop water intrusion before it impacts structural integrity. By removing excess moisture, you also lower the risk of mold, mildew, and poor indoor air quality, protecting both your property and the people inside.
Residential and Drainage Solutions (Nassau & Suffolk Counties)
Homeowners in Nassau and Suffolk Counties face unique challenges from high groundwater, coastal storms, and older housing stock. Premium Technical Services provides tailored drainage system designs that protect every part of your property, from basements to backyards, while also improving overall flow and preventing long-term structural damage.Â
Our basement drainage systems include interior channels and French drains that are expertly installed beneath or alongside concrete floors to capture and redirect water before it reaches your living space. For homes with crawl spaces, we combine crawl space drainage solutions, crawl space repair, and crawl space encapsulation to seal moisture out and prevent mold growth. These systems feature basins, sealed connections, and debris-resistant components that ensure reliable performance even during heavy storms.
Exterior options like yard and foundation drainage provide stormwater management for properties with steep grades or frequent pooling. Through sump pump and drainage integration, our team creates a connection between indoor and outdoor systems to keep water moving away from the structure. Using durable, moisture-resistant materials and advanced design, Premium Technical Services delivers a comprehensive solution that safeguards your home from foundation cracks, soil erosion, and costly repairs.

Whether you are breaking construction ground on a new project or upgrading an aging property, we engineer every drainage system to protect foundations, prevent cracks in walls and floors, and maintain structural integrity. Using proven methods like strategic gravel placement, sealed wall connections, and deep channel installations, we create systems that move water away from critical areas before damage occurs.
