Let Two Brothers Give the Rainwater Somewhere Better to Go
Surface Drains & Grading in Houston, Texas
☼
Does Rainwater Pool in Your Yard or Run Toward Your House?
Water flowing toward the house always wins eventually
Every Houston storm is a test of your lot's grading. If water runs toward the slab instead of away from it, it soaks the clay at the foundation edge, and that clay swells and shrinks with every cycle. Sticking doors, drywall cracks, and slab movement follow.
If water is reaching a door threshold, the garage, or the weep holes in your brick during heavy rain, treat it as urgent. Interior flooding costs far more than the drainage that prevents it.
Surface drainage is the fix for fast-moving stormwater: catch basins and channel drains that capture it, buried solid pipe that carries it, and regraded soil that gives every drop a slope to follow away from your foundation.

On a Flat Houston Lot, Slope Is Everything
Water obeys exactly one rule: it goes downhill. On a lot with real slope, that rule works for you. On the table-flat lots that make up most of Greater Houston, it works against you, because "downhill" is often a two-inch depression next to your slab.
Builders grade lots to drain when the house is new. Then a decade of settling soil, landscaping projects, new patios, and fence lines quietly reverses it. The lot that drained fine in 2012 now holds water in three places, and one of them is against the foundation.
Surface drainage is the craft of giving water a better offer: a basin lower than the puddle, a pipe with real fall, and a discharge point that is not your slab.
Sometimes that means catch basins and buried pipe. Sometimes it means reshaping the grade so water never collects at all. Usually it means both, designed together, which is why we assess the whole lot before proposing anything.
Signs Your Lot Needs Surface Drains or Regrading
Surface water problems show themselves during and right after rain. These are the ones worth acting on.
Water Pooling During Every Storm
Ponds forming in the same low spots every time it rains means the grade has nowhere to send the water. If one of those spots touches the slab, it is cycling the clay under your foundation.
Foundation drainage solutions ›Runoff Flowing Toward the House
Watch the water during a downpour. If sheets of it move toward the foundation instead of away, the lot is graded backward, and every storm delivers water straight to the slab edge.
Free structural assessment ›Water at Doors, Garage, or Patio
Water reaching a threshold or sheeting across a patio toward the house is one heavy storm away from coming inside. Channel drains across these paths are the standard fix.
Emergency foundation repair ›Soil Sloping Toward the Slab
Negative grade, where the ground beside the house sits higher a few feet out than at the slab, funnels every drop of roof and yard water to the foundation. Common on older lots where beds have been built up over the years.
Residential foundation repair ›Mulch and Soil Washing Out
Beds that empty into the lawn, gravel that migrates, and rills cut into soil after storms show water moving fast and unmanaged, usually from roof runoff with no path.
Gutter and downspout drainage ›Foundation Movement on the Wet Side
Cracks, sticking doors, and floor slope concentrated on the side where water collects. The ponding is not cosmetic anymore, it is moving the foundation.

Call 832-710-6957Catch Basin, Channel Drain, Swale, or Regrade?
Surface drainage is a toolkit, not a single product. Each tool solves a specific pattern of water, and most Houston lots need two or three working together.
| Solution | What It Does | Where It Fits |
|---|---|---|
| Catch basin | Collects ponding water through a grate into buried solid pipe | Low spots in lawns and beds where water sits after rain |
| Channel drain | Linear grate intercepting sheet flow across hard surfaces | Driveways, patios, pool decks, and garage entries |
| Regrading | Reshapes soil so water flows away from the foundation on its own | Negative grade at the slab, settled soil, built-up beds |
| Swale | Shallow graded channel steering runoff along a planned path | Property lines and side yards moving water to the street |
| Solid drain pipe | Carries collected water underground to a discharge point | Connecting basins, channels, and downspouts to the curb |
| French drain | Perforated pipe collecting subsurface water from saturated soil | Soggy ground that stays wet days after the storm |
If your problem is soil that stays saturated long after the rain stops, that is subsurface water and a different tool. See our french drain installation page.
Our Surface Drain and Grading Process
Free On-Site Drainage Assessment
We walk the lot, map where water enters, flows, and collects, check the grade around the full foundation perimeter, and take elevation readings to see whether the water has already caused movement. Written proposal, no obligation.
Mapping the Flow Paths
Every lot has a storm story: where the roof water lands, where the neighbor's runoff arrives, where the low spots hold. The design starts from that map, not from a standard layout.
Designing Basins, Channels, and Grade
Basin placement at the true low points, channel drains across sheet-flow paths, pipe runs sized and sloped for storm volume, and regrading where reshaping the soil solves it without hardware.
Establishing the Discharge
Collected water needs a legal destination: daylight at the curb, an approved storm connection, or a sump pump where the lot is too flat for gravity to finish the job.
Installation and Regrading
Utilities located, trenches cut with continuous fall, basins set level and low, pipe bedded and joined, and soil reshaped to positive slope away from the slab.
Restoration and Follow-Up
Sod and landscaping reinstated, and we return after heavy rain to confirm the system is moving water as designed. See our process and the methods we use.
Check Your Slope Before You Call Anyone
Here is a ten-minute check that costs nothing and will materially improve any conversation you have about drainage.
Walk the foundation perimeter and look at which way the ground falls in the first several feet from the slab. The standard target is soil dropping roughly six inches over the first ten feet, everywhere around the house.
You do not need instruments. A garden hose running gently at the slab edge tells you instantly which direction that spot drains. Anywhere the water travels along the foundation or sits in place instead of leaving is a spot worth photographing.
Then do the same check during a real storm, because rain reveals flow paths a hose cannot: the neighbor's runoff, the downspout torrents, the sheet flow off the driveway.
It also protects you commercially. A homeowner who can point to the exact three places the lot fails gets a scoped, specific quote instead of a one-size-fits-all system.
Piling Dirt Against the House Is Not Grading
There is a quick version of "fixing the slope" that gets done all over Houston: truck in soil and bank it up against the foundation until the ground looks like it falls away. It photographs well and it costs almost nothing.
It also buries the brick line, blocks the weep holes your walls use to shed moisture, holds damp soil against the structure, and invites termites by closing the inspection gap between soil and siding. And because the added soil compacts and settles, the "slope" often disappears within a couple of seasons.
Real grading moves water away without burying the house: soil is cut and shaped, not just added, and the slab edge keeps its clearance.
Where the lot genuinely has nowhere to shed water, no amount of added dirt fixes it. That is when basins, pipe, and a designed discharge earn their place.
If a quote is mostly a dirt delivery, ask where the water will go once the new soil settles. That question usually ends the conversation quickly, one way or the other.
Five Myths About Yard Drainage and Grading
Surface drainage looks simple, which is exactly why so much of it is done wrong.
Standing water after rain is just normal in Houston
Brief ponding during a downpour is normal. Water still sitting hours later, or sitting against the slab at all, is a grading failure, and every repetition cycles the clay under your foundation. Normal is water gone shortly after the storm. The test: if the same puddles form in the same places every storm, the lot is telling you where it fails.
A few bags of dirt will fix the slope
Banking soil against the house buries brick, blocks weep holes, and holds moisture against the structure, and the added soil settles back within seasons. Grading is cutting and shaping the lot so water leaves, not raising the ground until the problem is hidden. Worse still: soil above the slab line is a standing invitation to termites.
One catch basin will drain the whole yard
A basin only collects water that reaches it. If the grade does not deliver water to the grate, the basin sits dry while the puddles form ten feet away. Basins work as part of a design: placed at true low points, connected by sloped pipe, backed by grading that feeds them. What settles it: a flow map of the lot during rain, which is what our assessment builds.
Surface drains handle soggy, saturated ground
Surface drains catch moving water. Ground that stays saturated for days after rain is holding subsurface water that never reaches a grate, and that calls for a perforated french drain system instead. Installing the wrong one wastes the entire project. Right tool: see our french drain installation page.
Drainage can wait until after the foundation is fixed
Backward. Underpinning a foundation while water keeps ponding beside it leaves the mechanism running, and the soil keeps cycling around the new piers. Water management is part of the foundation repair, not an accessory to it. Right order: elevation survey first, then drainage and foundation repair as one coordinated scope.
Why Houston Lots Stop Draining
Lots that drained fine when the house was built fail for identifiable reasons. Finding yours determines the fix.
| Cause | What Happens | Typical Clue |
|---|---|---|
| Settled fill soil | Builder's grade sinks over years and reverses the slope | Ponding that did not happen when the house was newer |
| Built-up flower beds | Years of added mulch and soil raise grade above the slab line | Soil sitting high against brick, buried weep holes |
| New hardscape | Patios, walks, and driveways block old flow paths | Pooling that started after a construction project |
| Fence lines and edging | Boards and borders dam water inside the yard | Water held along the fence after storms |
| Uncontrolled roof water | Downspouts dump concentrated flow onto flat ground | Erosion and ponding near downspout exits |
| Neighboring construction | Raised adjacent lots send their runoff to yours | Water arriving from the property line during rain |
If roof water is the source, the fix starts at the downspouts. See gutter and downspout drainage.
What Affects Surface Drainage and Grading Cost in Houston
Surface drainage scopes range from a one-day regrade to a full lot system. These are the factors that move the number.
The main drivers are how much of the lot needs correcting and whether hardware or reshaping does the work. Regrading open lawn is straightforward. Threading pipe under a driveway or collecting water from six low points is a different proposition.
- Number of catch basins and channel drains required
- Total length of buried pipe runs
- Area of lawn or beds being regraded
- Access for equipment versus hand work
- Whether hardscape must be cut, bored under, or reinstated
- Discharge type: gravity to the curb versus sump pump
- Soil import, haul-off, and sod restoration
- Whether downspout piping joins the same scope
- Whether foundation repair is needed alongside the drainage
Worth planning for: bundling downspout piping into the same trenches while they are open is significantly cheaper than doing it separately later.

Six Questions to Ask Before You Hire
Yard drainage is sold by landscapers, sprinkler companies, and handymen, which is exactly where homeowners get confident answers from people solving the wrong half.
Is this surface water or subsurface water?
The question that decides the whole design. Ponding during storms is surface water. Ground soggy for days afterward is subsurface water and needs a french drain, not more grates.
Where exactly does the water discharge?
"Away from the house" is not an answer. You want a specific point: daylight at the curb, an approved connection, or a sump basin, legal and off your neighbor's lot.
Are you adding soil against the house?
If the plan raises grade above the slab line or buries weep holes, it trades a drainage problem for a moisture and termite problem. Grading should shape the lot, not bury the house.
How was basin placement decided?
Basins belong at the true low points water actually reaches, which takes measurement or storm observation. Basins placed by eye are how yards end up with dry grates next to standing water.
Did you check the foundation too?
If water has ponded against the slab for years, the foundation may already have moved. Elevation readings tell you whether you are buying one repair or two, and in what order.
Are the downspouts part of the plan?
Roof water is often half the volume the yard has to handle. A surface drainage design that ignores where the downspouts dump is solving half the problem.

Ponding water, backward grading, and flooded walkways are among the most common inspection findings and the most persistent tenant complaints in managed properties.
Buying or selling? A documented drainage assessment that defines exactly what the lot needs, and what it does not, replaces a scary inspection note with a priced, scoped repair, which is worth real money in a negotiation.
Managing property? We provide written assessments suitable for owner and board review, including an honest read on what can be monitored and what needs scheduling before the next storm season.

Still have questions about surface drains and yard grading? See some of our frequently asked questions below or contact us today.
What is a surface drain?
A surface drain collects stormwater at ground level, through a grated catch basin in a low spot or a linear channel drain across a hard surface, and carries it away through buried solid pipe to a discharge point. It handles the fast-moving water of an active storm, which is a different job from the subsurface seepage a french drain collects.
How much slope should my yard have away from the house?
The common target is ground falling roughly six inches over the first ten feet from the foundation, all the way around the house. Many Houston lots cannot achieve that everywhere, which is where catch basins, channel drains, and swales make up the difference by collecting what the grade cannot shed.
Do I need surface drains or a french drain?
Watch the timing. Water that pools or races during the storm and drains soon after is surface water, which needs basins, channels, or regrading. Ground still soggy a day or more later is subsurface water, which needs a french drain. Many Houston lots need both, and the assessment determines the combination.
Can you just regrade the yard instead of installing drains?
Sometimes, and when reshaping the soil solves it, that is the cheaper fix and the one we recommend. But regrading needs somewhere to send the water. On flat lots hemmed in by fences, neighbors, and hardscape, there is often no path to create, and that is when collected drainage earns its place.
Will pooling water really damage my foundation?
Over time, yes. Houston's clay swells when saturated and shrinks when it dries, and water repeatedly ponding beside the slab drives that cycle at one edge of the house while the rest stays stable. That differential movement is what cracks slabs, sticks doors, and slopes floors.
Where does the collected water go?
To a planned discharge point: daylight at the curb or a swale, an approved storm connection where the municipality permits it, or a sump basin with a pump where the lot is too flat for gravity. Discharge onto a neighboring property is not a plan, and a quote that cannot name the discharge point is incomplete.
Should soil be added against the house to fix negative grade?
Carefully, and often not. Soil banked against the house buries brick, blocks weep holes, holds moisture against the structure, and can invite termites. Correcting negative grade usually means cutting and reshaping soil away from the slab, and using drains where reshaping alone cannot move the water.
How much does surface drainage cost in Houston?
The range is wide because scopes range from a one-day regrade to a full lot system. Cost is driven by the number of basins and channels, pipe length, regraded area, equipment access, hardscape in the way, discharge type, and whether downspout piping or foundation work joins the scope. Assessments and written estimates are free.
Do you offer free drainage assessments?
Yes. We walk the lot, map where the water comes from and where it collects, check grade around the full foundation perimeter, and take elevation readings on the foundation. You get a written proposal at no cost and no obligation. Call 832-710-6957.
