Last Updated: November 11, 2026 - **Catch:** downspouts, low spots, side swales - **Carry:** solid pipe at a steady fall - **Release:** to the street, never the neighbor ## Water running down the driveway into the garage? When a driveway or patio tilts toward the house, every storm sends a sheet of water across the concrete to the door. A channel drain cuts across that path and takes the water before it gets there. [Clay Plano Drainage Company](https://clayplanodrainagecompany.com/) installs channel drains at driveways, garage aprons and patios in Plano and nearby cities. We cut the concrete, set the channel, pipe it to a legal outlet and patch the slab to match. ## What happens on the first visit A channel drain is only as good as its height and its outlet, so we measure both before choosing a length or a grate. - **Where the sheet flow starts.** The street, the drive approach, a roof valley above the garage, or the patio itself. - **Slab heights.** Spot elevations across the apron or patio show the low line where a channel belongs. - **The garage floor.** If it sits below the apron or the street, the outlet has to sit lower still. - **The outlet.** Fall to an emitter in the lawn, an existing line, or the curb. - **The concrete.** Joints, cracks and thickness at the edge, and where a cut would land. You get a written estimate with the channel length, grate, outlet route and patch area. ## Where a channel drain goes Most home channels go in one of three places. Each one sets a different length, grate and outlet. ### Across the driveway or garage apron Across the drive near the garage door, catching water before it reaches the threshold. The grate takes car tires, and the channel sits in a concrete haunch so its edges don’t break under the load. A steep drive can need its channel a few feet out from the door, where the flow is still spread out. ### Along the house edge of a patio Patios settle, and one that tilts toward the slab sends rain to the back door. A channel along that edge catches it and carries it to the side, where it can head for the street. Foot-traffic grates work here, and slotted or decorative grates suit pavers. ### Walks and courtyards boxed in by walls Where a walk runs between the house and a wall or a raised bed, water has nowhere to go. A short channel at the low point, piped under the wall or along it, gives it an exit. ## Picking the channel and grate Channels differ in width, depth, material and how they get their slope. We match each one to the water it has to carry and what crosses it. - **Material.** Polymer concrete channels are heavy and rigid and hold their line in a driveway. PVC channels are lighter and suit patios and walks. - **Slope.** Some systems are made in sections that step down to the outlet. Others are flat and get laid on a slight fall. - **Outlet.** An end outlet suits a shallow cut; a bottom outlet drops straight into the pipe below. - **Grate.** Plastic for patios, galvanized steel or cast iron for drives. A slotted heel-proof grate suits a patio where people walk in dress shoes. The estimate names the channel, the grate and why each fits. ## Water from the street Some driveway water starts in the street. When the gutter overflows in a big storm, water can climb the drive approach toward a garage that sits lower than the curb. A channel at the garage handles what reaches the apron. The street, the curb and the drive approach belong to the city, and in Plano paving and drive approach work in the right-of-way needs the city’s Engineering Permit. Changes there are a permitted project, not a quick fix. > When a channel can't empty > > If the garage floor sits below the street and no outlet anywhere is lower, gravity can’t drain the channel. A [yard sump and pump](https://clayplanodrainagecompany.com/sump-pump-drainage/) can lift the water, or the fix starts upstream. ## How the channel goes in A channel drain is concrete work as much as drainage work. The cut, the support around the channel and the patch decide whether it stays flat and level with the drive. 1. **Locates and layout.** Texas811 marks buried lines, and we snap the cut lines on the concrete. 2. **Saw-cut.** We cut straight, clean edges and remove the strip, following joints where they fall close. 3. **Dig and set.** We excavate below the channel, then set it to line and fall. Some channel systems step down section by section; flat sections get laid with fall. 4. **Haunch.** Concrete goes in under and around the channel body, so the paving edges, not the channel, carry the load. 5. **Isolation joint.** Where the channel runs beside the foundation, a joint keeps the new concrete from bonding to the slab. 6. **Outlet.** Solid pipe leaves the end or bottom outlet at a steady fall to the emitter, line or curb. 7. **Patch and test.** We finish the concrete to the surface around it, set the grates and run water across the paving. Concrete poured around the channel so the paving edges carry the load. ### Why the grate rating matters Grates are rated for what crosses them. A patio grate under a car tire cracks or pops out, and a loose grate is a trip hazard. On driveways we use vehicle-rated grates, and locking grates where they could be kicked loose.

That includes the saw-cut, the channel and grate, the concrete patch and a solid line to an outlet; your written estimate sets the figure. The area of concrete cut and patched moves it most, then the grate’s load rating, the length, the outlet run and whether it’s a drive, a patio or an apron.

Lift a section, rinse out the channel and flush the outlet line with a hose. If the channel overflows even when it’s clean, the outlet is the likely limit, and a puddle beside the drive may be a separate [standing water](https://clayplanodrainagecompany.com/standing-water-in-yard/) problem.

A trench drain, also called a channel drain, is a grated channel set into paving that catches water running across the surface. A French drain is a buried trench of stone and perforated pipe that collects water held in the soil. One handles a sheet of runoff; the other handles wet ground. ### My driveway slopes down to the garage. Is a channel drain enough? It catches what runs down the drive, as long as its outlet sits lower than the channel. If the garage floor is below the street and no outlet is lower, the channel fills and stops. Then the water needs a pump, or the source needs fixing where it starts. ### Can a channel drain sit right against my foundation? It can run close, but it shouldn't be bonded to the slab. We set an isolation joint between the channel's concrete and the foundation, and we make sure the channel carries water away to an outlet instead of holding it beside the beam. ### Do I need a heavier grate for a driveway? Yes. A grate made for a patio cracks or pops loose under car tires. Driveway and apron channels get grates rated for vehicle loads, set in a concrete haunch so the edges carry the weight instead of the channel body. ### How much concrete gets cut out? A strip a little wider than the channel, plus room for the concrete haunch around it, cut along straight lines. Where the line lands near a joint, we follow the joint. The estimate shows the patch area, because it moves the price as much as the length does. ## Related services - [Service**Catch basins** A grated box set at the lowest point of a lawn, bed edge or patio that takes in surface water and sends it through solid pipe to an outlet.](https://clayplanodrainagecompany.com/catch-basins/) - [Service**Yard grading** Reshaping the soil so the ground falls away from the slab and toward a swale or the street, set to measured slopes instead of guesswork.](https://clayplanodrainagecompany.com/yard-grading/) - [Service**Commercial drainage** Drainage for HOA common areas, retail centers and office lots: inlets, trench drains, storm tie-ins and grading, built to engineered plans where the city requires them.](https://clayplanodrainagecompany.com/commercial-drainage/) ## Get an estimate for channel drains Tell us where the water stands and when.
