Protect Your Foundation from Water Damage with Expert French Drain Solutions
There’s a spot in your yard that turns into a swamp every time it rains. Or water pools along your foundation and you worry about what it’s doing to your home. Maybe your lawn stays soggy for days, and you’re tired of tracking mud through the house or watching your landscaping slowly deteriorate.
When water doesn’t drain properly from your property, it creates problems that go way beyond inconvenience. It threatens your foundation, ruins your yard, and turns what should be usable outdoor space into a muddy mess you avoid.
A properly installed French drain solves these problems by giving water a clear path away from where it’s causing issues. It’s not complicated—it’s just good drainage design that works with gravity to move water where you want it instead of where it’s creating headaches.
At Foundations First Texas, we install French drains that actually fix drainage problems. We look at your specific property, figure out where water’s coming from and where it needs to go, and install a system that handles it. If you’re dealing with standing water, foundation concerns, or a yard that won’t dry out, let’s talk about whether a French drain makes sense for your situation.

Types of French Drain Installations Done by Foundations First Texas
Depending on where your drainage problems are, different French drain installations make sense:
Exterior French Drains
These are installed outside your home, typically around the foundation perimeter or in problem areas of your yard. They’re the most common type for residential properties and handle surface water and shallow groundwater that’s causing issues around your foundation or in your landscaping.
Basement French Drains
Installed inside around the perimeter of a basement, these intercept water that’s seeping in through the foundation. They typically direct water to a sump pump that then pumps it out and away from your home. If you’re dealing with basement moisture or flooding, an interior French drain is often part of the solution.
Crawl Space French Drains
Similar concept to basement drains but installed in your crawl space. These keep your crawl space dry by intercepting groundwater and directing it away before it can pool or create moisture problems that lead to mold, wood rot, or structural issues.
Each situation is different, and sometimes a combination of systems makes the most sense. When we evaluate your property, we’ll figure out which approach actually solves your specific drainage problems.
Problems French Drains Solve
French drains handle a range of water-related issues that San Antonio homeowners commonly face:
Standing Water in Your Yard
That low spot that turns into a pond after every rain? A French drain intercepts the water before it can pool, moving it away from that area and letting your yard actually be usable. No more muddy messes, no more waiting days for spots to dry out.
Water Pooling Around Your Foundation
When water sits against your foundation, it’s causing problems you might not see right away—soil erosion, hydrostatic pressure, potential for cracks and leaks. A French drain installed around your foundation’s perimeter intercepts that water and directs it away before it can cause damage.
Soggy, Waterlogged Lawn Areas
Grass that stays wet doesn’t thrive. It becomes muddy, grows poorly, and creates dead zones in your landscaping. Proper drainage lets your lawn actually drain and dry out between rains, giving grass and plants a chance to establish healthy root systems instead of drowning.
Basement or Crawl Space Moisture
If water is getting into your basement or crawl space, a French drain installed along the interior perimeter can intercept groundwater before it enters, channeling it to a sump pump or drainage point. For exterior installations around basement walls, it prevents water from ever reaching your foundation in the first place.
Unusable Outdoor Space
If sections of your yard are too wet to enjoy, you’re essentially losing usable property. Kids can’t play there, you can’t landscape it properly, and it becomes an eyesore you just avoid. Fix the drainage, and you reclaim that space.
The right French drain system addresses whatever specific water problems your property has—and most homeowners notice the difference immediately after the first rain.
Our French Drain Installation Process
1. Property Assessment
We start by looking at your property and understanding where water’s coming from, where it’s causing problems, and where it needs to go. We’ll identify the slope, check soil conditions, look at existing drainage, and figure out the best approach for your situation.
2. Custom Design
Every property is different, so every French drain system we install is customized. We design the system based on your specific terrain, drainage challenges, and goals. We’ll explain what we’re recommending and why it makes sense for your property.
3. Professional Installation
We handle the entire installation—digging the trenches at the proper depth and slope, laying the pipe correctly, using appropriate gravel and filter materials, and making sure everything is connected and functioning properly. We use quality materials and proven installation methods that actually work in San Antonio’s soil conditions.
4. Site Cleanup and Restoration
Once the drain is installed and tested, we backfill and restore the disturbed areas, leaving your property clean and the work site in good condition. You’ll have a functioning drainage system without the mess.
5. Testing and Verification
Before we’re done, we verify that the system is working—that water flows properly through the drain and exits where it’s supposed to. You’ll see for yourself that the problem is solved.
The whole process is usually completed in one to two days for most residential installations, depending on the size and complexity of the system.

Our French Drain Installation Process
For those interested in the technical aspects of French drain systems, here’s what goes into a professional installation:
Crawl Space French Drain Installation
Preparation and Planning
- We identify high and low points in the crawl space to ensure proper water flow
- The drainage path is planned so the drain ends at the lowest point and begins at the highest
- We ensure adequate slope (minimum 1% grade) for effective drainage
Installation Process
- Trenches approximately 4 inches deep are excavated following the planned path
- A base layer of clean river rock may be added depending on soil conditions
- Perforated pipe with filter sock is placed in trenches, sloping toward the discharge point
- System is tested to verify proper flow
- Trenches are backfilled with clean river rock to allow maximum water flow
Materials Used
- Perforated pipe with filter sock (prevents soil infiltration)
- Clean river rock or gravel
- Discharge components as needed
Basement French Drain Installation
Preparation
- Work area is protected with plastic sheeting to contain dust and debris
- We mark drain placement along foundation walls
- Necessary sections of concrete slab are carefully removed (typically 10 inches from foundation wall)
Installation Process
- Trenches are excavated 4-6 inches below the foundation footing
- Proper slope (1% grade) is maintained toward the collection/discharge point
- A base layer of clean river rock is placed in trenches
- Perforated pipe with filter sock is installed
- Drainage mat is placed against foundation wall to direct water into the system
- Vapor barrier covers the rock and mat to prevent moisture migration
- Concrete is repoured to match existing slab
- Work area is thoroughly cleaned
Materials Used
- Perforated drainage pipe with filter sock
- Clean river rock
- Drainage/dimple mat for foundation wall protection
- Vapor barrier (6-mil plastic)
- Concrete for restoration
Exterior French Drain Installation
Installing an exterior French drain is similar to a crawl space installation. Before digging, make sure you’re not running into any gas, water, or power lines.
Preparation
- We locate and mark any underground utilities before excavation (gas, water, electric, cable lines)
- Drainage path is planned with proper discharge location
Installation Process
- Trenches 12-18 inches deep and approximately 9 inches wide are excavated
- Proper slope (1% grade minimum) is established throughout
- Discharge system (catch basin or pop-up emitter) is installed at endpoint
- Base layer of clean river rock is placed in trench
- Appropriate pipe type is installed (perforated sock pipe or triple-wall pipe depending on specifications)
- Pipe is connected to discharge system
- Trench is backfilled with clean river rock
- Landscape fabric may be used with triple-wall pipe installations
- Surface is restored and graded for proper water flow
Materials Used
- Perforated sock pipe or triple-wall drainage pipe
- Clean river rock
- Pop-up emitter or catch basin discharge
- Landscape fabric (when specified)
