When water builds up behind a basement wall, it has to go somewhere. If it has no clear path to the sump pit or a daylight drain, hydrostatic pressure builds against the wall and the floor, and the water finds its own way in.

Hydro Channel is designed to solve that problem. It gives basement water an unobstructed path to a sump pump or daylight drain, so the water moves out instead of pushing back on the foundation.

What hydrostatic pressure does to a basement

Ground water saturates the soil around a foundation. With nowhere to drain, that water pushes against the wall and up through the slab. Over time, that pressure shows up as seepage at the cove joint, efflorescence on the wall, and cracks that keep coming back after you have sealed them.

If you have been called back to the same wall more than once, check whether the water still has a way out. Sealing the crack alone will not stop the pressure that caused it.

Where Hydro Channel fits

The Hydro Channel line is designed to better manage ground water hydrostatic pressure buildup. It is built to keep a clear, unobstructed path open so basement water can reach a sump pump or daylight drain.

The line includes:

• Hydro Channel, the standard channel for the run along the base of the wall.
• Hydro Channel Plus, for jobs that need more capacity.
• Hydro Channel Plus Corner, for turns where the run changes direction.
• Hydro Bridge, for crossing over an obstruction in the path.

You can review the full line and product details on the Hydro Channel collection page.

Plan the path before you install

A channel only works if the water can get to it and then out of the system. Before you install, check these points:

1. Confirm the outlet. Know where the water is going, whether that is a sump pit or a daylight drain, and confirm it can take the flow.
2. Look for obstructions. Check for debris, footings, or anything else that could block the path.
3. Plan the corners. Each turn in the run changes how water moves, so map the route before you cut.
4. Check the drainage outside. Grading and downspouts that send water back toward the foundation will undo the work inside.

Match the product to the run

Use the standard Hydro Channel for a straight run along the wall. Use the Plus version when the job calls for it, the Plus Corner where the run turns, and Hydro Bridge where the path needs to cross an obstruction. Check the product page for specifications before you order.

The short version

Basement water causes problems when it has no clear way out. Hydro Channel gives it one. Plan the outlet, clear the path, and make sure the outside grading is not sending water back to the wall.
