12''X30'PLASTIC ROAD TILE DOUBLE

Product Overview

A 12″ × 30′ dual‑wall drainage pipe is designed for stormwater conveyance and subsurface drainage systems. These pipes feature a smooth interior wall to promote efficient water flow and a corrugated exterior wall to provide structural strength under soil loads. Constructed from high‑density polyethylene (HDPE), this type of pipe is lightweight, resistant to corrosion and abrasion, and commonly used as an alternative to concrete or metal pipe in storm drains, French drains, culverts, and landscape drainage systems. The ADS N‑12 pipe line also offers multiple joint styles (plain end, bell & spigot with gasket for soil‑tight or watertight connections), depending on the product configuration.

Key Features

Nominal Diameter: 12 in

Length: 30 ft (reduces joint count and installation time)

Material: High‑density polyethylene (HDPE) — corrosion and chemical resistant

Wall Construction: Dual wall corrugated exterior; smooth interior for improved hydraulics

Hydraulic Performance: Smooth interior typically has low resistance (Manning’s n ~0.012) for efficient water flow

Joint/Connection Options:

Plain end for use with couplers

Bell & spigot (soil‑tight or watertight) with gaskets for secure connections, depending on model

Standards: Often manufactured to meet AASHTO M‑294, ASTM F2306 and related drainage standards

Benefits

Promotes efficient water movement and reduces clogging potential.

Lightweight for easier transport and installation compared with concrete alternatives.

Durable HDPE resists corrosion, abrasion, and soil chemicals.

Long 30 ft sticks mean fewer joints and faster installation.

Typical Applications

Yard or landscape drainage runs.

Stormwater conveyance under grading and slope control.

French drain and foundation perimeter drainage systems.

Roadside and agricultural drainage projects.
