What NDS Certification Actually Means
NDS is the leading manufacturer of professional drainage products in North America. NDS Certified Professional Drainage Contractor is a credential earned through structured training in drainage hydrology, system design, materials, and installation. Most contractors who claim to do drainage have never sat through any of it. Three things you get from a certified contractor that you do not get from a landscape crew with a trencher:
Drainage hydrology training
Not just installing pipe. Designing for water volume, flow rate, soil percolation, and slope. Most "drainage" contractors are landscapers running a trencher and guessing at depth.
Engineered system design
Sized to roof load, lot grade, soil type, and water source. The system is calculated, not guessed. Pipe diameter and slope match the volume the system must move.
Certified materials and methods
Proper Schedule 40 PVC and virgin HDPE installation. Correct slope, filter fabric, outlets, cleanouts. Methods that hold up for 30-plus years instead of failing in three to eight.
We do not use corrugated black pipe. Period. The cheap drainage system every other contractor in Jacksonville installs is the exact reason we get called in to redo it three to eight years later. Schedule 40 PVC and virgin HDPE 4-inch 8-slotted are the only acceptable materials for serious drainage work.
What NDS Certified Work Looks Like in the Field
- Pre-install soil percolation assessment where it matters. Sandy soil drains, clay does not. The design changes accordingly.
- Calculated pipe sizing. Diameter scaled to roof area and rainfall intensity. A 4-inch line moves a fraction of what a 6-inch line moves; the wrong size guarantees backup.
- Engineered slope. Typically 1/8 inch per foot minimum for gravity systems. Too flat backs up; too steep silts at the bottom.
- Filter fabric sock around slotted HDPE to prevent silt clog. Without it, the system fills with fines within a season or two.
- Washed #57 stone backfill, not native soil. Native soil packs and chokes the channel. Washed stone keeps percolation high.
- Designed outlets. Daylight at grade, pop-up emitter at property edge, or engineered stormwater tie-in. Never dumped at the property line and forgotten.
- Catch basins sized to surface water volume, not picked off a shelf because they fit the hole.
- Cleanouts placed for long-term maintainability. The system is rod-able, jet-able, and inspectable years later.
Why NDS Certification Matters in Florida
Florida is the hardest drainage environment in the country to get right. Five things make standard out-of-state drainage practice fail here:
- Sandy soil drains fast but unpredictably. Clay pockets stop water cold. Both can exist in the same yard.
- High water tables, especially near the coast and the St. Johns and Intracoastal corridors. A trench can fill with groundwater before the pipe ever gets installed.
- Salt-air corrosion on hardware. Galvanized fasteners, exposed metal grates, and cheap catch basins fail fast within a few miles of the ocean.
- Hurricane-grade rainfall volume. Florida storm intensity is among the highest in the country. A system sized for "average" rainfall floods every named storm.
- New construction grading. Most subdivisions leave drainage as an afterthought, dumping water from one lot onto the next. The original grade is rarely the right grade.
NDS Certified vs Landscape Company With a Trencher
The difference is not subtle. Here is what you get from each:
| Spec | Landscape Company | NDS Certified Contractor |
|---|---|---|
| Pipe | Corrugated black pipe, 4-inch, whatever is on the truck | Schedule 40 PVC for routing, virgin HDPE 4-inch 8-slotted for French drains |
| Sizing | Picked by feel | Calculated to roof area and rainfall intensity |
| Backfill | Native soil shoved back in the trench | Washed #57 stone, filter fabric sock |
| Slope | Eyeballed | Engineered to 1/8 inch per foot minimum |
| Outlet | Dumped at property line | Daylight, pop-up emitter, or stormwater tie-in by design |
| Cleanouts | None | Placed for long-term maintainability |
| Lifespan | 3 to 8 years | 30-plus years |
| Warranty | 1 year if any | Lifetime workmanship |

Drainage Is Half the Project. Gutters Are the Other Half.
Water hits the gutter, exits the downspout, then the drainage takes over. The two halves must work together. Gutter Pro is the only major Northeast Florida contractor that designs and installs both as one engineered system, with one crew, under one lifetime warranty. See our drainage solutions hub for the full drainage scope and seamless gutters for the gutter side.
How an NDS Certified Install Works
- Free on-site scope walk. Albert walks the property, evaluates grade and water sources, checks soil and existing failures, and documents the design constraints. Typically scheduled within 48 hours of your call.
- Engineered design. Pipe diameter and slope calculated to roof area and rainfall load. Soil percolation factored. Outlet type chosen. Material spec'd. The system is on paper before any shovel hits the ground.
- Detailed written quote. Itemized: linear feet of pipe by material, French drain depth and length, catch basin count and size, outlet design, restoration scope, timeline. No vague "drainage allowance."
- 811 utility locate before any digging. Required and never skipped.
- Excavation to engineered depth and slope. Trenches cut by the same crew that will install the pipe, not subcontracted out.
- Install to NDS spec. Filter fabric sock on slotted HDPE. Schedule 40 PVC solvent-welded and pressure-tested. Washed #57 stone backfill. Cleanouts placed. Outlets installed and functional before backfill closes.
- Restoration and walkthrough. Sod or fill restored. Site cleaned. Albert walks the finished system with you. Lifetime workmanship warranty starts the day we leave.
NDS Certified Drainage FAQ
What is NDS Certification?
NDS is the leading manufacturer of professional drainage products in North America. NDS Certified Professional Drainage Contractor is a credential earned through structured training in drainage hydrology, system design, materials, and installation. Owner Albert Urbank holds the credential and is one of few certified contractors in Northeast Florida.
How is an NDS Certified contractor different from a landscape company doing drainage?
A landscape company runs a trencher and rolls out corrugated black pipe with native soil backfill, no calculated slope, no filter fabric, no designed outlet, no cleanouts. An NDS Certified contractor calculates the pipe size, uses Schedule 40 PVC and virgin HDPE, washed #57 stone, filter fabric sock, engineered slope, and a designed outlet. The first fails in three to eight years. The second lasts 30-plus.
Why does drainage hydrology training matter?
Because moving water is math. A 4-inch pipe moves dramatically less water than a 6-inch pipe. Slope, soil percolation, and outlet type all change what the system can actually handle. Without the underlying hydrology, every "drainage" install is a guess, and most of them guess wrong.
What materials does NDS Certification require?
Solid-wall pipe for routing (Schedule 40 PVC), slotted pipe for collection (virgin HDPE 4-inch 8-slotted), filter fabric sock around the slotted pipe, washed clean stone backfill, manufactured catch basins and outlets sized to water volume, and cleanouts. Not corrugated black pipe and native soil.
How do you size a drainage system?
Pipe diameter is scaled to roof area contributing water to the system and to the peak rainfall intensity expected in Northeast Florida. French drain length and depth are scaled to the saturated soil area and the design flow rate. Catch basins are sized to surface water collection volume. Outlets are sized to system capacity. The whole thing is calculated before excavation.
What is the difference between Schedule 40 PVC and HDPE for drainage?
Schedule 40 PVC is solid-wall, glued at joints, and used for underground routing where the pipe must move water from collection point to outlet without losing any. Virgin HDPE 4-inch 8-slotted is used inside French drain channels where the pipe must collect water through the slots and along its length. Solid pipe for moving water, slotted pipe for collecting it.
Why do most cheap drainage installs fail in 3 to 8 years?
Three reasons. Corrugated pipe collapses under soil load. Native soil backfill chokes percolation and silt fills the channel. No filter fabric means fines migrate into the pipe within a season or two. The combination guarantees failure on a predictable timeline. Every drainage redo we get called for has those three failures in common.
How does Florida soil affect drainage design?
Florida soil is rarely uniform. Sandy zones drain fast and dewater quickly. Clay pockets hold water and back up the system. High water tables near the coast and rivers can flood a trench before the pipe is even installed. NDS Certified design accounts for all three; uncertified drainage usually does not.
Do you do soil percolation testing?
Where it matters, yes. On dry wells, deep French drains, and any system relying on soil infiltration as the outlet, we test percolation before specifying the system. On systems with daylight outlets or stormwater tie-ins, percolation is less critical and is assessed by visual and walk-through evaluation.
What slope do French drains need?
Minimum 1/8 inch per foot of fall for gravity systems. Less than that and water sits in the pipe and silt builds up. Too much and water moves too fast to fully drain saturated soil along the trench length. The engineered slope is calculated for each install based on outlet elevation and run length.
What is the right outlet for a French drain?
Three options. Daylight at grade, where the pipe simply exits the slope and water flows out under gravity. Pop-up emitter, which opens under flow and seals when dry to keep debris and animals out, used where the outlet sits at property edge. Stormwater tie-in, where municipal code and infrastructure allow connection to the public system. The right outlet depends on lot grade, property line, and local code.
How long does an NDS Certified drainage system last?
30-plus years for the underground piping itself, installed correctly. Catch basins, grates, and pop-up emitters may need occasional cleaning. Sump pumps last 8 to 12 years and are replaceable. The core system outlasts the house when installed to NDS spec.
How much does NDS Certified drainage cost vs a cheap install?
A certified install typically runs 30 to 60 percent more than a landscape-company drainage job at install. The certified system lasts 30-plus years; the cheap install fails in 3 to 8. The total cost of two or three redos plus collateral foundation and landscape damage is usually three to five times the cost of doing it right once.
Do you provide warranty on drainage work?
Lifetime workmanship warranty on labor and materials, same as our gutter work. Product warranties on sump pumps, catch basins, and pop-up emitters carry the manufacturer's terms. Schedule 40 PVC and virgin HDPE are warranted to outlast the install.
