Road Drainage Systems
With proper road drainage systems in place, you can prevent costly pavement failures, reduce liability, and improve the longevity of your paving project. RDC Paving delivers reliable drainage systems designed to protect commercial parking lots, roads, and concrete surfaces across Central Texas.

Parking Lot and Road Drainage Systems
Poor drainage can hurt your property’s appearance while increasing long-term maintenance costs. Without a well-planned drainage system, water can begin to pool on your pavement, causing potholes, cracks, and other extensive damage.
RDC Paving’s drainage services create solutions that manage runoff effectively, so your parking lot and roadways stay stronger for years to come.
Our Drainage Process
Planning & Design
We perform a thorough site assessment to identify water movement patterns, the existing infrastructure’s condition, and more. This information helps us customize your new drainage and utility system.
Excavation & Installation
We remove the existing pavement and underlying soil to dig trenches for the new drainage and utility lines. Our contractors use high-quality materials to create long-lasting drainage systems that perform under heavy rainfall.
Backfilling & Restoration
After installation, we carefully backfill, compact, and restore the surface to its original condition, ensuring safety and seamless integration with the surrounding pavement. This ensures your road drainage system is built to last.
Why Proper Drainage Systems
Are Necessary in Texas
Heavy rainfall, freeze-thaw cycles, and sudden storms in Texas create ideal conditions for water to build up and damage parking lots and roadways. Without proper drainage, this water seeps into the pavement base, weakening the structure and accelerating surface failures. A proper drainage system can help:
- Minimize Soil Erosion: Directing water flow prevents soil washout beneath your pavement.
- Prevent Floods: Well-designed road drain systems keep water moving, reducing the risk of standing water.
- Protect the Ecosystem: Managing runoff helps limit pollutants from entering waterways.
- Improve Pavement Lifespan: Less water infiltration means fewer cracks, potholes, and long-term repairs.
Types of Parking Lot & Road Drains
Surface Drainage Systems
- Grading & Sloping: Ensures pavement and parking lots are angled correctly so water flows away instead of pooling.
- Curb & Gutter Installations: Directs stormwater safely into drains instead of eroding pavement edges.
- Valley Gutters/Flow Lines: Concrete channels that carry surface water toward inlets.
- Concrete Swales/Spillways: Shallow channels that move runoff across paved or landscaped areas.
Stormwater Management Systems
- Storm Drain Installations and Repairs: Includes catch basins, inlets, and manholes tied to storm sewer systems.
- Retention/Detention Basins: Temporarily hold runoff to prevent flooding during heavy storms.
- Permeable Pavements: Specialized mixes that let water filter through the surface, reducing runoff and protecting the base.
Subsurface Drainage Systems
- French Drains/Trench Drains: Gravel-and-pipe systems that remove water beneath or alongside pavement.
- Edge Drains: Installed along road or lot edges to intercept water before it seeps into the base.
- Pavement Underdrains: Perforated pipes beneath pavement to prevent base failures caused by trapped water.
Concrete Drainage Structures
- Headwalls & Endwalls: Installed at pipe outlets to prevent erosion and stabilize slopes.
- Box Culverts: Large precast concrete channels designed for high-volume water flow.
- Concrete Aprons/Spill Pads: Reinforce pipe discharge areas to prevent erosion and washouts.

How Poor Drainage Impacts
Your Parking Lot
When water has nowhere to go, it damages your property from the ground up. Poor drainage can lead to:
- Accelerated Pavement Deterioration: Standing water weakens the pavement base, causing cracks and potholes.
- Liability Risks: Slippery surfaces and uneven pavement increase the chance of accidents.
- Reduced Property Value: A parking lot or road with visible drainage issues can look unprofessional and discourage tenants or customers.

Road Drainage Systems FAQs
Without adequate drainage, water can accumulate beneath your pavement, leading to base layer erosion, cracking, potholes, and premature surface failure. Proper drainage protects both the surface and the foundation of paved areas.
Common indicators include:
- Standing water near buildings or on pavement
- Water flowing toward structures instead of away
- Erosion near curbs, sidewalks, or driveways
- Cracking or sinking pavement
A drainage system uses gravity to move water away from paved areas. In a gravity-fed system, water flows down sloped channels into a catch basin that filters debris. From there, it travels through a series of pipes to nearby sewers or drainage outlets.
