At a Glance: Key Applications
Use Waterstop Streamline – Straight for: Replacing screed hobs in linear showers, creating fall control, and providing a fully integrated waterproofing and screen solution.
Waterstop Streamline – Straight: A Technical Overview
The Straight (1 Leg) model of Waterstop Streamline is engineered to suit linear shower designs along a single wall. Fabricated from 6463–T5 aluminium, this profile acts as both a screed guide and a waterproofing barrier. It allows the shower screen to be sealed directly to the waterproofing membrane, eliminating the need for grout contact and reducing leak risk. The integrated tile gauge ensures consistent fall-to-waste during screeding, saving install time while ensuring AS 3740:2021 compliance.

- Apply membrane right under the bullnose lip
- Only remove protective tape after all trades are complete
Avoiding Common Issues
- Do not install over dusty or uneven substrate
- Avoid solvents and abrasives on finished surface
- Ensure screen base is hard-set to bullnose with silicone
Storage & Shelf Life Considerations
Store in original box in a dry, flat area. Keep protective tape intact until final installation stage.

Frequently Asked Questions About Waterstop Streamline – Straight
Q: Can the straight profile be trimmed onsite to custom lengths?
A: Yes. Waterstop Streamline straight profiles can be cut to size using a standard drop saw or hacksaw. Always trim before waterproofing begins.
Q: Does this work for timber and concrete substrates?
A: Yes. For concrete, apply directly. For timber, many waterproofers membrane the full floor before installing Streamline, then membrane again inside the shower.
Q: Do I still need to build a hob?
A: No. Waterstop Streamline completely replaces the traditional brick or timber hob. It performs both formwork and waterproofing barrier roles.
Q: Will it support a frameless shower screen?
A: Yes. The lip and bullnose are designed to accept silicone-bonded frameless, semi-frameless, and framed screens securely.
Q: What tile thickness does it suit?
A: The built-in tile gauge is designed to suit tile and adhesive systems ranging from 6 mm to 10 mm overall thickness.

Applying Waterstop Streamline – Straight: Protocols & Best Practices
General Application Steps:- Prep: Mark position with pencil on floor. Ensure clean surface. Use spirit level to plan alignment.
- Sealant: Run continuous urethane sealant bead between pencil lines. Apply masking tape to Streamline lip before placement.
- Install: Press profile into position, ensuring level contact. Adjust low areas with tiler’s wedges if necessary.
- Membrane: Apply 2 coats of waterproofing inside the shower area, ensuring coverage under bullnose.
- Screeding: Screed up to tile gauge edge. Leave 15 mm clearance from tile top to hob top.
- Tiling & Glazing: Tile flush to both sides. Remove protective tape. Apply silicone between screen and Streamline lip.
