§ 02 / Benefits

Why deck-level piped.

01

Falls managed

Drainage gradient is built into the gutter system — not dependent on the structural deck fall. Water moves to the outlet regardless of minor structural variation.

02

Flush finish

The gutter profile sits flush with the deck surface. No raised channels, no trip hazards, no visible drainage infrastructure. Clean, continuous deck plane.

03

Rapid access

End caps are removable. Access gutters have lift-out covers. The entire drainage run can be rodded or inspected without lifting the deck surface.

§ 03 / Components

System components.

AD-AG-50

Access gutter

50mm profile. Sits flush with deck surface. Provides rapid drainage and maintenance access.

AD-OC-100

Outlet connector

Connects gutter run to piped drain below deck. Multiple configurations for different structural arrangements.

AD-DLO-50

Deck-level outlet

50mm diameter floor outlet with integrated debris guard. Point drainage for isolated low spots.

AD-PC-75

Piped channel

75mm round pipe routed below joist level. Carries water from gutter to primary drainage system.

AD-CP-50

Corner piece

90° bend connects gutter runs at deck corners. Factory-formed for consistent angle and watertight joints.

AD-EA-50

End cap with access

Removable end cap for rodding and inspection. Quarter-turn removal, no tools needed.

AD-JC-50

Joining coupler

Connects gutter lengths with watertight slip joint. Accommodates thermal movement along the run.

AD-DG-50

Debris guard

Stainless mesh insert for access gutter and outlets. Prevents leaf and debris ingress to the pipe run.
