Uncoupling Membrane Guide: Preventing Tile Cracking and Enhancing Installation Uncoupling Membrane: A Key Solution for Preventing Tile and Stone Cracking

In developed countries like the United States and Europe, industry documents such as those published by TCNA (North American Tile Association) and ANSI (American National Standards Institute) have clearly written uncoupling membrane technology into the association standards and installation specifications. In certain scenarios, it has become a mandatory or recommended solution. However, in China, it is still in its early stages.

Why Tiles and Slabs Always Crack?

During conventional laying processes, the sub-base, tile adhesive, and tiles form an integrated whole, known as coupling. However, due to the inconsistent expansion coefficients of the sub-base and tiles, such as the common thermal expansion and contraction, in an integrated structure, once stress is transmitted, cracks are likely to occur.

Directly laying tiles with tile adhesive cannot buffer stress, and once cracks appear, the repair cost is very high. Replacing the tiles and relaying them is not only costly but also a hassle.

What to Do? tetti's Uncoupling Anti-Cracking System

This system is a tile and stone anti-cracking solution with an uncoupling anti-cracking pad at its core. (Hereinafter referred to as "uncoupling pad").

The uncoupling pad is mainly made of HDPE and PP non-woven fabric using special technology. Its core function is to eliminate the coupling phenomenon, providing a separation layer between the sub-base and tiles, allowing the two parts to move independently, blocking the transmission of stress, and significantly reducing the risk of cracking on the surface of tiles and stones.

Where to Use? Uncoupling Pad Compatible Scenarios

Residential or commercial spaces: Ground laying scenarios (including underfloor heating).

Finishing materials: Tiles, slabs, stones, natural or artificial stone floors, etc.

Leveling sub-base: Plywood or定向刨花板, concrete, vinyl, plaster, etc.

What Are the Benefits? tetti's Uncoupling Anti-Cracking System Advantages

Tile anti-cracking: Unique dovetail structure separates stress, significantly reducing the risk of cracking. Earth warming even temperature: Scientific groove design allows for efficient and uniform distribution of heat from underfloor heating. Waterproofing and moisture-proofing: High-density polyethylene material blocks water vapor penetration, preventing mildew. Superior load-bearing capacity: Columnar mortar structure disperses pressure, with a maximum load-bearing capacity of up to 550kg/㎡. Increased adhesion: Tenon structure interlocks with tile adhesive, ensuring firm bonding. Saves space: 3mm/7mm ultra-thin design, making living spaces more spacious.

How to Choose? Three Anti-Cracking Solutions

U3 Uncoupling Anti-Cracking Pad - Classic anti-cracking solution

3mm thickness, double-layer structure, quick construction, suitable for regular laying anti-cracking

U3i Imported Uncoupling Anti-Cracking Pad - Advanced anti-cracking solution

German original import, 3mm thickness, three-layer structure, better uncoupling and anti-cracking effect

U7 Electric Heating Anti-Cracking Pad - Electric heating anti-cracking solution

7mm thickness, preferred for local underfloor heating installation, quick heating, more energy-saving

How to Install? Official Uncoupling Pad Installation Guide

Key steps for uncoupling pad laying:

Sub-base needs to be flat, structurally stable, and surface clean without impurities. According to the space size, cut and leave a 3-5mm expansion joint. Choose C2 level or above tile adhesive, and the full-pouring rate should reach 95% or more. Special treatment should be done at junctions.

FAQ: What You Care About Is What We Care About

Q: Can uncoupling pads be used in old house renovations?

A: Yes, they can be directly laid on the existing tiles, saving the cost of removal.

Q: Can uncoupling pads be used in bathrooms?

A: Yes, they can. The high-density polyethylene material is waterproof and moisture-proof, but it is necessary to do a good job in the waterproofing node treatment.

Q: How long can uncoupling pads last? Will they age?

A: tetti uses a new high-density polyethylene material, with strong weather resistance, and will not age in an enclosed space, with a life of over 25 years, theoretically, it can have the same lifespan as the building.

Q: Can uncoupling pads be used on underfloor heating? Will it affect the temperature?

A: Yes, they can be used. In a 11℃ environment, after comparison tests, the temperature of the underfloor heating will drop by about 3℃ after laying the uncoupling pad, but after the heat passes through the air channels, the heat emitted by the thermal imaging instrument shows that the temperature is more uniform, and the user feedback is also more comfortable.
