When it comes to designing and constructing tiled showers, one crucial aspect that demands meticulous attention is ensuring watertightness. In order to achieve this, the installation of waterstops play a vital role. Complying with the Code of Practice: Internal Wet Area Membrane Systems is not only a matter of adhering to regulations but also a way to guarantee the long-term durability of your tile shower.
In this blog, we will shed some light on some of the guidelines outlined in the Code of Practice and explore the importance of waterstop installation in tiled showers.
Code of Practice: Internal Wet Area Membrane Systems
The Code of Practice: Internal Wet Area Membrane Systems serves as a comprehensive guide for industry professionals involved in the design and construction of wet areas. This code outlines the minimum requirements, installation procedures, and recommended practices for internal wet area membrane systems, including the installation of waterstops in tiled showers.
What is a waterstop?
A waterstop is a material used to prevent water from penetrating areas vulnerable to leakage, such as joints and corners within a shower. In tiled showers, it acts as a critical line of defense against moisture infiltration, helping to maintain the integrity of the waterproofing system. The waterstop is typically installed during the construction phase, before applying the waterproofing membrane and the tile finishes.
Importance of Waterstop Installation
Preventing Water Damage
Without proper waterstop installation, water can seep into the substrate, causing damage over time. This can lead to mould growth, deterioration of structural components, and costly repairs. By effectively sealing vulnerable areas, a waterstop acts as a safeguard, ensuring water remains within the shower enclosure.
Complying with regulations
Building codes and standards, such as the Code of Practice: Internal Wet Area Membrane Systems, provide guidelines and requirements for the construction of tiled showers. Adhering to these regulations is crucial to meet safety standards, avoid legal issues, and protect the interests of both the occupants and the builders.
Longevity and durability
Waterstop installation is an investment in the long-term durability of the shower area. It enhances the lifespan of the entire waterproofing system, protecting it from premature deterioration. By minimizing the risk of water damage, the waterstop contributes to the overall structural integrity of the shower.
Key Considerations for Waterstop Installation
Selection of appropriate waterstop
Selecting the right waterstop depends on factors such as the type of shower, anticipated movement, and compatibility with other building materials. Currently, the most commonly used waterstop is the aluminium L angled, however, we would suggest the appropriate as in the below figures.
Proper Positioning
Waterstops should be installed in areas prone to movement and water ingress, such as corners, joints, and floor-wall intersections. Ensuring proper alignment and secure fixing is crucial to achieve effective waterproofing. Pay attention to the continuity of the waterstop around the entire shower perimeter.
Compatibility with other components
The waterstop should be compatible with the waterproofing membrane and tile adhesives used in the shower. Compatibility ensures optimal performance and prevents chemical interactions that could compromise the effectiveness of the system.
Regular inspection and maintenance
Even with proper installation, regular inspection and maintenance are essential to identify any signs of damage or deterioration in the waterstop. Timely repairs or replacements can prevent potential leaks and maintain the shower’s watertightness.
In Conclusion
The installation of a waterstop is an indispensable component of creating a watertight tiled shower. Complying with the Code of Practice: Internal Wet Area Membrane Systems is essential to ensure your tiled shower is watertight.
