Conroe drainage work is mostly underground systems. The lots are wooded, the ground has more fall than it does in Houston proper, and homeowners generally do not want an open swale cut across a yard they have spent money on.
Pipe and structures price differently: pipe and French drains by the linear foot, catch basins and inlet boxes by the structure. More pipe and bigger pipe both move the number, and on a wooded Conroe lot the route usually has to work around root systems worth keeping.
Where a property runs toward Lake Conroe or a feeder creek, the outfall has to be handled so the drainage fix does not create an erosion problem at the discharge point. Those two jobs are related here more often than not.
What this covers in Conroe
- Underground pipe systems routed around mature trees
- French drains along foundations and in chronic wet areas
- Catch basins and area drains where water collects
- Outfall protection so discharge does not erode the bank
- Downspout collection tied into the main system
How the work runs in Conroe
Find where the water actually goes
We watch the fall across the property and locate the outfall — a ditch, a storm inlet, or daylight at a low corner. Everything upstream depends on where water is allowed to leave.
Choose the method the site allows
Open swale, swale and pipe, a full underground system, or an underground system with a lift station are four different jobs at four different costs on the same size lot.
Install at real slope
Pipe is bedded and laid to a working fall with clean-outs. Flexible hose buried shallow crushes and blocks within a season, which is why we do not use it.
Test it with water, then restore
The system is run before the trench is closed, and disturbed ground gets seed or sod so it does not become the next erosion problem.
Underground Drainage in Conroe — common questions
- Why does water stand in my Conroe yard?
- Almost always one of three things: the ground has no fall toward an outfall, the soil is heavy clay that will not take water quickly, or the water arriving from uphill is more than the yard can move. The fix is different for each, which is why we look at where the water actually goes before quoting a solution.
- What does a French drain actually do?
- It intercepts water moving through the soil, not just water standing on top of it. A perforated pipe in a gravel-filled trench collects that water and carries it to a discharge point. It only works if it is bedded at a real slope and tied to an outfall that is legally and physically able to take the flow.
- How much does yard drainage cost?
- Pipe, French drains, and channel drains price by the linear foot; catch basins, area drains, and inlet boxes price by the structure. The bigger factor is which method the site needs: an open swale, swale-and-pipe, a full underground system, or an underground system with a lift station are four different costs on the same size lot.
- Will this fix water against my foundation?
- That is usually the priority, and it is normally two jobs together: regrading so the surface falls away from the slab, and perimeter drainage so water in the soil is intercepted before it reaches it. Ground that stays saturated against a foundation is what turns a drainage nuisance into a much more expensive problem.
