When it comes to landscaping, many homeowners focus on plants, patios, and aesthetics. But beneath it all lies something even more important: drainage and grading.
If your yard doesn’t drain properly, it can cause costly problems like water damage, erosion, dead plants, and foundation issues. As a trusted Landscaping company, Greenbay Northern treats drainage and grading as essential foundations of every landscape design—especially suited to Ontario’s diverse terrain.
Here’s what you need to know.
What Is Grading?
Grading is the process of shaping the land’s surface to direct water flow. It ensures that:
- Water drains away from your home and foundation
- Outdoor areas stay dry and functional
- Soil erosion is prevented
We often adjust grading during the construction of patios and walkways or retaining walls to ensure long-term drainage performance.
What Is Drainage?
Drainage refers to the systems and techniques used to remove or redirect water from your yard. This includes:
- Surface drains and French drains
- Gravel beds and swales
- Proper grading and slope
- Permeable interlocking surfaces
Our team incorporates both visible and hidden drainage features that blend seamlessly into your landscape.
Why Are Grading and Drainage So Important?
1. Protect Your Home’s Foundation
Poor drainage can lead to water pooling near your foundation — causing cracks, leaks, and long-term damage. A properly graded yard slopes water away from your house.
2. Prevent Erosion and Mudslides
Water flowing downhill without control will carry away soil and mulch, ruin plant beds, and destabilize slopes. Retaining walls and smart grading can prevent these issues.
3. Keep Lawns and Gardens Healthy
Too much water can drown your lawn, rot plant roots, and breed fungus or pests. Good drainage protects your garden and lawn health.
4. Extend the Life of Hardscape Features
Standing water can damage stone joints, freeze and crack pavers, or undermine walkways. We design interlocking projects with slope and drainage in mind.

Signs You Have a Drainage Problem
- Water pooling after rain
- Soggy or muddy lawn areas
- Basement dampness or flooding
- Washed-out mulch or exposed roots
- Puddles near patios or walkways
If you notice any of these issues, it’s time for a drainage assessment.
