Drainage Service FAQs
How do I know if my property has a drainage problem?
Common signs of drainage issues include standing water after rain, soggy or unusable areas of your yard, water pooling near your foundation, basement dampness or flooding, and soil erosion on slopes. If left unaddressed, these problems can lead to foundation damage and costly repairs.
What is the difference between surface drainage and foundation drains?
Surface drainage systems manage water on top of the ground using swales, culverts, or grated drains to redirect runoff. Foundation drains, such as French drains or footing drains, are installed below ground to move water away from foundations, basements, and crawl spaces, protecting the structure from water intrusion.
Can drainage issues cause foundation damage?
Yes. Poor drainage can lead to hydrostatic pressure against foundation walls, causing cracks, water seepage, and long-term structural damage. Proper drainage solutions help relieve this pressure and protect the integrity of your home or building.
Do you offer drainage solutions for sloped or difficult properties?
Absolutely. BWP & Sons Excavation specializes in drainage solutions for challenging sites, including sloped properties and areas with heavy runoff. We use grading, erosion control, retention basins, dry wells, and underground drainage systems to manage water safely and effectively.
Do drainage systems require permits in New Hampshire?
Some drainage projects may require permits depending on the scope of work, proximity to wetlands, or impact on stormwater flow. BWP & Sons Excavation is familiar with local regulations and can help determine permit requirements for your specific project.
