Most Tile Suppliers Still Use Mesh Backing
Even Though They Know It Fails

The truth is simple: mesh backing was never engineered for pools. Yet it’s sold daily for underwater installations.
At PoolTile.ca, we decided to do better.

Stop the Failure — Choose DOT SYSTEM

Why Mesh Fails When It Meets Water

Here’s what most manufacturers don’t admit: mesh-backed mosaics were
made for dry surfaces — not for long-term underwater exposure.

The Hidden Flaw Most Pools Never Survive

Mesh-backed tiles might hold up fine on a backsplash, but submerge them in water and the glue starts to weaken. The result? Detached tiles, stains, and endless repairs. When the mesh absorbs moisture, the adhesive loses grip — creating invisible failures beneath the surface.

Blocked Adhesion

The glue and mesh prevent proper bonding. Up to 40% of the tile surface never adheres to the thinset.

Moisture Entrapment

Moisture trapped between the tile and mesh fuels mould and bacterial growth.

Chemical Breakdown

Chlorine and pool salts degrade the mesh glue, leading to detachment and crumbling.

Progressive Weakness

Mesh deteriorates over time, causing tiles to pop or shift years earlier than expected.

Introducing DOT SYSTEM
The Backing Engineered for Pools

Unlike mesh, DOT SYSTEM is built for the underwater world — offering stability, precision, and strength that last a lifetime.

Engineered for Underwater Excellence

With DOT SYSTEM, each tile is supported by strategically placed silicone dots — allowing 92% surface contact with adhesive for unmatched bonding. It’s the only system scientifically designed to endure chlorine, water pressure, and shifting temperatures without compromise.
