Fixing a Soggy Lawn in Vancouver: Drainage Solutions Beyond Sand

Why Sand Alone Won’t Solve Drainage

Spreading sand over a wet lawn is a common misconception. Sand helps water penetrate the surface (reducing runoff) but does not fix underlying drainage. On heavy clay, core aeration followed by filling holes with sand can gradually improve structure over years, but it’s not a quick fix for a soggy lawn.

Wait and Observe

In the Pacific Northwest, wet winters are normal. Give the lawn a chance this spring and summer. If standing water causes rot, then consider more drastic measures: remove the sod, install drainage tile, and re‑sod or re‑seed.

When to Act

• If the lawn remains waterlogged well into the growing season.
• If grass dies off in low spots.
• If mosquitoes and insects become a persistent problem.

Start with core aeration and organic amendments to improve soil porosity. If that fails, consult a drainage contractor for a permanent solution.
