French drains
Collect water below the surface and give it a route away from the house. The layout depends on the source of the water and where it can discharge.
French drains & foundation waterproofing
Give water a way out.
Protect the home you love.
Pooling water, a damp crawl space, or a side yard that never dries? Let’s talk about what’s happening and whether drainage or exterior waterproofing makes sense for your home.

Start with the signs
Still seeing water
beside the house?
Maybe the side yard stays wet after every storm. Maybe water collects against the house or a damp patch keeps returning downstairs. Start by telling us where you see it and when it happens.

Foundation waterproofing
Protect the outside of the foundation with a system suited to the wall and the site. Drainage and waterproofing are planned together.
03Move collected water
Sump pumps
When gravity cannot carry water to a suitable outlet, a sump basin and pump may be part of the solution. We can discuss whether your site needs one.

which drain you need.
Tell us where the water collects, when it happens, and your city. We’ll discuss the next step and whether a site review makes sense.

On the job in Berkeley, California
A closer look at
one of our projects.
This Berkeley home had a narrow concrete path along the side of the house. Our crew opened the path to reach the foundation, installed the drainage components, and restored the surface. Here’s how the work came together.
Follow the work below, including the pipe and gravel before backfill. Select any photo to enlarge it. The final concrete image is labeled as a retouched finish preview.
CHAPTER 01
First, we opened
the side path.
The existing path ran between the house and the planting bed. Working in that narrow space meant removing sections of concrete and excavating along the wall.
With the trench open, we could reach the part of the foundation that had been below ground.

Next came
the wall preparation.
Before applying the wall coating, our crew worked along the exposed foundation to prepare the surface.
Much of this work disappears from view later. We photographed it along the way so the preparation would remain part of the project record.

Then we added
the wall protection.
The next photos show the wall coating being applied, followed by a textured drainage layer along the foundation.
These layers do different jobs. The barrier helps resist water entry, while the drainage layer provides a path for water to reach the collection system.

The pipe went in.
Then came the gravel.
We laid the drainage pipe along the wall, then placed gravel in the trench. These photos show both stages before the work was covered.
The pipe is only one part of the system. The gravel, filter fabric, and discharge route all need to work together.

More than
just backfill.
The close views below show the gravel around the drainage pipe. The spaces between the stones let water move toward the pipe.
Clean, washed stone limits the fine material that can clog a drain. Filter fabric helps keep the surrounding soil out of the gravel.

A basin and pump
complete the next stage.
Our crew also worked on the collection basin and pump equipment. These photos show the equipment while it was still accessible.
If your project needs a pump, we’ll discuss the equipment, power supply, discharge route, and maintenance as part of the proposed scope.

Finally, we restored
the concrete surface.
After the drainage installation, we replaced concrete along the edge of the house. The path began to take shape again.
The image below is a retouched preview of a more uniform finish. The earlier project photos show the installation beneath the surface.

View full photoAfter the work
A little attention
after each storm.
Keep gutters, surface inlets, and accessible outlets clear. After a storm, look for new pooling or changes in drainage. If something looks different, contact your installer.
What affects the estimate?
The cost depends on the length and depth of the drain, access, excavation, hauling, wall condition, materials, discharge route, and any pump or surface restoration work.
What will the proposal include?
The proposal should explain the work area, materials, discharge approach, and restoration, along with what is included and excluded. Timing and any required approvals should be discussed before work begins.

Review the recommended work, price, and expected schedule before deciding how to proceed.
Before you call
Common questions.
Do I need a French drain, waterproofing, or both?
It depends on where the water comes from and how it reaches the house. A site review helps us determine whether drainage, exterior waterproofing, or both make sense for your property.
Can you give me a price over the phone?
We can talk through the project over the phone. A firm price depends on the scope, access, existing conditions, and discharge requirements.
Where do you work?
We work in San Francisco and the Bay Area. Tell us your city when you call so we can confirm availability.
What should I have ready?
Your property location, a description of the affected areas, and when the problem appears are a good start. You can text photos to (628) 215 1005 or email office@gogreenlands.com.
Will a French drain fix every water problem?
No. Roof runoff, surface grading, plumbing leaks, and groundwater may need different responses. First, we need to understand the source and where the water can go.
Is waterproof paint the same as exterior waterproofing?
No. An interior coating does not create an exterior water management system. Exterior work addresses the outside face of the wall and may combine waterproofing with drainage.
How long will the work take?
Timing depends on access, excavation, weather, and the final scope. We’ll discuss the expected schedule in the proposal.
Will the call connect directly to extension 0?
