Piedmont North Carolina sits on heavy red clay that doesn't drain well, on rolling hills that funnel water in unexpected directions, and gets some of the heaviest rain events in the eastern US. If you have soggy spots in the yard, water in the basement, eroding hillsides, or dying grass — you have a drainage problem.
Most landscapers treat drainage as an afterthought. We treat it as engineering. Every drainage solution we install starts with understanding where the water comes from, where it goes, and how to redirect it without creating a problem somewhere else on your property — or your neighbor's.
Our most common solutions are French drains, dry creek beds (river rock channels), surface grading, sump pump installations, and downspout extensions. We often combine them with retaining walls when erosion is also at play.
We walk your property, identify water sources, and diagnose the real cause of the problem.
After we diagnose the cause on-site, we send a clear plan with options and pricing — no upselling.
Trenching, pipe work, gravel, river rock, grading — done with care for your existing landscape.
We test the system, restore disturbed areas, and walk through with you to confirm it works.
Drainage isn't a one-size solution — it's engineering. The difference between a drain that lasts decades and one that clogs in a year is in the details. Here's what every Garrison's drainage project gets.
