FAQs

Where can I buy Waterstop Streamline from?

Waterstop Streamline can either be purchased direct from the manufacturer (Gleda Pty Ltd) or from a range of Tile retailers and Waterproofing supply retailers. For further information please refer to the "How to order" page on our website.

What height is the angle?

The extrusion used measures 65mm in total height, which allows an adequate fall to waste for even the largest of shower designs. This height has been calculated in order to comply with AS3740, and the various tiling standards in different states regarding screed thickness at the waste. Making the hob any lower makes it difficult to comply with AS3740's requirements of 15mm protrusion above finished tile height, whilst still maintaining sufficient fall to waste and enough screed thickness at the waste. For further information, including section drawing with dimensions, please refer to our Technical Information page.

Can I use any shower screen with the product? Sliding Screens? Frameless Screens?

Waterstop Streamline has been in use for over 20 years and more than 500,000 shower screens have been fitted to the product without issue. If you have any concerns though, please talk to the screen installer/supplier.

The Streamline works with most screen types. With sliding screens, the sliding part runs in a channel at the bottom and the channel installs to the Streamline the same way as a normal screen.

With frameless screens, the important point is that the cavity formed between the Streamline and the glass panel be completely filled with silicon before the panel is pressed into place. This avoids bubbles which can be seen through the glass. You can use different coloured silicones, but even clear will provide enough opaqueness to hide the membrane. For across the door opening, once the finished tile height is known, the screen supplier can glue or silicon a strip of moulding of suitable width across the doorway to hide the membrane.

How do you join it at the corners?

Waterstop Streamline does not require any assembly on site as it is fabricated from one piece of extrusion and comes ready to fit. For available sizes and styles please look at the Streamline Fact File

Can I trim or cut it on site?

It is common to find installers trimming one or both legs of the product on site to suite out of square bathroom walls or to fit a rectangular shape shower design. You can simply use a standard hacksaw. Remember to measure twice and cut once!

I have a very large shower to build that has some odd angles. Can you make a special size?

Yes, Gleda offers a custom build service for non-standard shapes and sizes. Please also be aware that many uneven configurations can easily be cut on site from standard product. For further information please refer to the custom made section in our product range.

Can the product be repaired if it is damaged after installation?

Yes, Gleda has developed a repair system that can be used once installed. However, we have found that due to the high quality and robust nature of the finish and the thick protective tape used to protect the product whilst being installed there have been very few issues with damage.

Does the product comply with the Building Code and Australian Standards?

Yes, in fact Waterstop Streamline was developed by a group of waterproofers, tillers, screen installers and building construction supervisors after learning that the standard was about to change in 2004. The code and standard refer to the need for a waterstop to be fitted to all enclosed shower cubicles and that the waterstop must protrude above the finished tile height by no less than 5mm. In the case of a raised hob, the protrusion above finished tile height must be 15mm. The latest 2021 revision of the standard lists those same requirements. Waterstop Streamline complies with this standard and at the same time is the most simple and reliable way to ensure long-term waterproof performance.

Will it cost more than what I am using currently?

The simple answer is NO. In general most builders find the benefits and savings are significant. This has resulted in major developers and builders such as Devine Homes, Choice Homes, AV Jennings, Phillip Usher Constructions, Coral Homes, Clarendon Homes and many, many others all using Waterstop Streamline.

Information on the hidden costs faced by builders is available in our Technical Information.

Is there a warranty?

Gleda provides a manufacturing warranty that covers any faults with the product for a period of six years and six months. Damage caused by installation or miss-use is not covered; however, Gleda has developed a system for repair in-situ.

Who can install them?

Waterstop Streamline simplifies shower construction and replaces other common materials like aerated cement block and standard aluminium or plastic angles. The installation process utilises all common waterproofing techniques and therefore any licensed waterproofer, tiler or builder authorised to perform waterproofing in buildings is able to fit this product.

What waterproofing membrane can I use with the product?

Waterstop Streamline was developed for and is most suited to liquid applied membranes. There are many brands and versions of liquid applied membranes to choose from. Waterstop Streamline is fabricated from aluminium extrusion and is compatible with almost all liquid membranes. The responsibility for compatibility of waterproofing products used in conjunction with this product remains with the installer.

What do you recommend we stick or screw it down with?

Waterstop Streamline has been designed with a large serrated horizontal base leg (40mm wide) to allow very strong adhesion when gluing the angle to the substrate. Most installers use a flexible sealant that is compatible with the membrane they use to form the shower tray. Using metal fasteners risks promoting Galvanic Corrosion which could result in damage to the alloys used to manufacture the Streamline extrusion. We do not recommend fixing the angle with screws or any other form of penetration. Gluing with a urethane type sealant will be more than adequate and will allow the angle to be levelled easily. For further information please refer to our installation instructions.

How much of the product remains above the tiles and in view?

There are two common methods of shower design/installation that affect the appearance of the finished product - direct stick or bedded tiles on the bathroom floor. If you choose the direct stick method of tiling for your bathroom floor (outside of the shower) you will see approximately 40mm of the Waterstop Streamline product. If you choose to bed the bathroom floor before tiling the amount of the Waterstop Streamline product remaining in view will depend entirely on how high your tile bed is raised. Either method creates a streamline modern appearance that will outlast most other bathroom fittings. For further information please refer to our installation instructions.

How does the shower screen connect to it?

All shower screen systems have fixing points along their vertical connections with the walls and usually have very little, apart from a bead of silicon, to connect with the floor. Waterstop Streamline provides a secure, straight and precise vertical leg for the base of the shower screen to rest against. Any common screen floorframe, sill extrusion or frameless glass will easily connect to Waterstop Streamline. For further information please refer to our installation instructions.

I am renovating my bathroom; can I use Waterstop Streamline?

Waterstop Streamline is commonly used with many bathroom/shower renovations. The only requirement to consider is the demolition of your existing shower structure, which needs to be taken back to bare floor substrate. Once the floor substrate is exposed you will be able to start constructing your new shower with Waterstop Streamline. For further information please refer to our installation instructions.
