Expert System for Tactile Paving and Tactile Walking Surface Indicators in Europe

SOZI EOOD is a European manufacturer of tactile paving tiles and tactile walking surface indicators, designed for real-world use in accessible environments, public buildings and infrastructure projects. This expert system aims to explain what tactile paving is, how it functions in real conditions and how it should be correctly designed and installed.

Tactile paving is often mistakenly perceived as a decorative or standard floor tile. In reality, it is a functional orientation and safety element for people with visual impairments, and incorrect application may lead to disorientation and increased risk during movement.

What tactile paving is and why it is not a decorative element

Tactile paving (also referred to as tactile ground surface indicators or tactile tiles in search queries) are specialized surface indicators that transmit information through touch, either by a white cane or underfoot. Their primary function is guidance, warning and spatial orientation within the built environment.

Installing tactile paving without understanding its functional role turns it into an ineffective or even hazardous element. For this reason, tactile paving must not be treated as a visual or decorative solution, but as part of a coherent accessibility system.

How a visually impaired person navigates space

A visually impaired person perceives space sequentially, through tactile feedback and logical spatial cues. Movement is based on a clear system: a guiding line, an attention field or a stopping signal. Any interruption, chaotic layout or incorrect combination of tactile elements breaks this logic.

An effective tactile guidance system must be predictable, consistent and functionally justified. This principle forms the foundation of the SOZI expert system.

Real installation conditions and existing floor coverings

In practice, tactile paving is most often installed in operating facilities such as pharmacies, hospitals, schools, administrative and public buildings, where floor coverings like porcelain tiles, concrete or stone already exist.

In such cases, removing the existing floor is technically or economically unjustified. Therefore, surface installation on existing floors is a widely accepted and valid solution, provided specific technical and functional requirements are met.

Flexibility as a critical requirement for tactile paving

Real floor substrates are rarely perfectly level. When installed over existing surfaces, excessively rigid tactile tiles may deform, fail to adhere evenly and create raised edges.

For this reason, controlled flexibility of tactile tiles is a functional requirement rather than a compromise in quality. Flexible materials ensure uniform contact, reliable bonding and long-term safe use, especially in retrofit installations.

Core principles of a correct tactile guidance system

function before form or visual design
clear logic of movement and orientation
continuity and consistency
sufficient contrast with the surrounding surface
adaptation to real installation conditions

Regulatory and technical framework

The SOZI expert system is developed in accordance with ISO 23599:2019 – Tactile Walking Surface Indicators and European accessibility principles. Compliance is supported by certification, declarations of conformity and internal production control.

Structure of the SOZI expert system

This page defines the core principles for proper design, installation and use of tactile paving in real built environments. Subsequent sections address specific topics such as types of tactile tiles, installation on existing floors, material flexibility, adhesive selection, outdoor use and the role of certifications and technical data sheets.
