TECHNICAL EXPERTISE / LIQUID WATERPROOFING

Different liquid systems suit different roof conditions.

A system that works well on a dry timber deck may be wrong for damp concrete, a trafficked balcony or an old bituminous roof. The starting point is always the surface, moisture, movement, exposure and the details that need to be waterproofed.

THE SYSTEM LIBRARY

Start with the roof condition, then choose the product.

My liquid-waterproofing work covers three distinct manufacturer portfolios. They overlap in some applications, but their technologies, preparation requirements, reinforcement strategies and routes to guarantee are different.

SHARED SYSTEM COMPONENTS

Roof edge & detailing trims.

Pre-formed GRP trims are used to form drip edges, upstands, wall fillets, corners, cover flashings, expansion details and other roof terminations. These profiles can be used with a wide range of compatible liquid-applied waterproofing systems.

Compatibility first

A trim only works when it is prepared and connected to the membrane correctly. Profile choice, surface preparation and installation method should be checked against the selected waterproofing system.

ROOF EDGE + DETAILINGOne coordinated range. Multiple working profiles.
ACTUAL SUPPLIED RANGE

Choose the profile by the roof geometry and working dimension—not by the code alone. Standard straight profiles are supplied in 3 m lengths; F-series flashings are 20 m rolls.

01GUTTER EDGE / A-SERIES

Drip trims

Forms the lowest roof edge and directs water cleanly into the gutter.

Dimension note: codes describe the profile family; girth, depth, flange, cover and upstand dimensions describe the actual geometry. Final compatibility remains system- and detail-specific.

TECHNICAL SUPPORT

Some roofs need more than a quick product recommendation.

01System comparison

Compare the practical fit of Winkler, Res-Tec and Scott Bader technologies without treating products as direct equivalents.

02Build-up review

Coordinate substrate preparation, primers, reinforcement, edge details and final exposure.

03Installer support

Turn technical data and training requirements into a controlled site sequence.

04Project route

Identify when standard supply is appropriate and when specified or special-order systems are required.

TECHNICAL SCOPE NOTE

These pages are intended to help with early product and system discussions. Project selection should be confirmed after reviewing the substrate, current manufacturer information and the proposed roof build-up.
