Allthrough Balcony Drain

The Allproof Allthrough is a unique solution to meet the requirements of multi-level balcony drainage. The system features a closed sleeve for straight through levels and an open sleeve for levels where the surface drainage needs to be allowed to feed into the down pipe. The unit is suitable where a floating deck/tile application is being used or a membrane finish balcony.

The Allproof Allthrough is not applicable when discharging roof drainage through the system.

Scope of Use

The Allthrough is a stainless steel clamp ring and flange that connect into a down pipe, the clamp ring has an open and closed option for required functions.

The flange is to be rebated into the balcony substrate with membrane dressed into, the Allthough clamping ring is then installed directing the down pipe directly into the flange. Tile jacks or decking can then be placed installed onto the balcony provideing the finished surface. When an open Allthough is used this will then allow drainage of the balcony though the down pipe and removes the requirements of further drainage fittings around the balcony. A closed Allthough is used in a situation on the same system where the drainage of the balcony is not required.

Limitations on Use

This product has been designed for balcony installations.

Please note the compatibility with waterproof membranes when selecting a flange option, especially if a heat applied membrane is going to used.

Statement of Building Code Compliance

Accepted Alternative Solution to meet standards required to protect penetrations in membrane deck while also allowing downpipes to pass though.
