Tactile strips, also known as tactile floor strips, are essential tools used in public and private spaces to improve accessibility for visually impaired pedestrians. These strips create textured surfaces that are easily detectable underfoot, providing vital information about the surrounding environment. In this guide, we’ll walk you through the process of laying stick-on tactile strips, also known as peel-and-stick tactile strips, which are especially useful for retrofitting existing pavements or floors. These self-adhesive tactile strips are cost-effective and easy to install, offering a hassle-free solution for improving safety and accessibility.
Tactile paving, also referred to as tactile ground surface indicators (TGSI), includes various types of raised patterns designed to provide navigation assistance. These patterns are crucial for individuals with visual impairments as they offer guidance and warning of potential hazards. Tactile strips are typically installed in areas such as pedestrian crossings, railway platforms, stairways, and ramps. The strips' different patterns, including raised domes, bars, or lines, are strategically designed to indicate either hazard warnings or directionality. Stick-on tactile strips are a preferred option as they are versatile, easily applicable to existing surfaces, and suitable for various environmental conditions. They also offer quick installation without requiring extensive construction work.
Before laying tactile strips, the surface where they will be applied must be properly prepared to ensure the adhesive bonds effectively. Begin by inspecting the existing surface for any imperfections such as cracks, debris, or moisture. Any loose materials or dirt should be thoroughly cleaned using a broom or vacuum. For stubborn residues like oil or grease, use an appropriate cleaner to ensure the surface is free from contaminants.
If applying tactile strips to a non-porous surface, such as tiles or polished concrete, it's advisable to lightly scuff the surface with sandpaper. This will improve the adhesion of the tactile strips. Furthermore, the surface must be completely dry before proceeding. Any moisture present can interfere with the adhesive, causing the strips to fail over time.
Once the surface has been cleaned and prepared, you can begin laying the tactile strips. First, plan the layout by determining the areas where the tactile strips will be placed. Ensure that the tactile pattern is oriented correctly. For example, directional bars should align with the intended travel path of pedestrians.
To install the tactile strips, carefully peel off the release liner from the adhesive backing and position the strip onto the prepared surface. It’s important to place the strip precisely the first time, as repositioning may weaken the adhesive. Press down firmly, applying even pressure across the entire strip, starting from the center and moving outward to avoid air bubbles.
For corners, curves, or areas where tactile strips need to be cut, use a utility knife to trim the strips to fit the contours of the surface. Always ensure that the cuts are clean and smooth to maintain the strip’s functionality and aesthetic appeal.
Choosing the right tactile pattern is crucial to ensure the intended functionality of the installation. Here are some common tactile patterns and their uses:
Blister / Dome Pattern: Used for warning pedestrians about potential hazards, such as at crossings or platform edges. The raised domes are detectable underfoot and alert individuals to the presence of a danger.
Directional / Guidance Bars: Ideal for guiding visually impaired individuals along paths or corridors. These bars are placed parallel to the intended walking direction and help guide pedestrians to their destination.
Hazard / Corduroy Pattern: Used at stairs, ramps, or platform edges where there is a change in elevation. This pattern warns pedestrians to approach with caution.
Platform Edge / Offset Blister Pattern: Often used in transit areas, such as train or bus platforms, to warn individuals of the platform edge or track zones.
After installation, tactile strips should be regularly inspected to ensure that they are still in good condition. Check for signs of wear or damage, such as lifting edges or worn-out surface patterns. If any part of the strip becomes detached or damaged, it should be replaced immediately to maintain its functionality.
In outdoor environments, regular maintenance is even more critical due to exposure to weather elements. Clean the strips periodically to prevent debris from accumulating, and check that the adhesive is still intact. For heavily trafficked areas, tactile strips may need to be replaced more frequently to ensure safety.
Stick-on tactile strips offer several advantages over traditional concrete or metal tactile slabs:
Quick Installation: Peel-and-stick tactile strips are easy and fast to install, without the need for heavy machinery or invasive construction work. This makes them an ideal choice for retrofitting existing surfaces.
Cost-Effective: Stick-on strips are typically more affordable than traditional tactile paving slabs, offering a budget-friendly option for improving accessibility.
Versatility: These strips can be applied to a variety of surfaces, including concrete, tiles, and existing paving, without requiring major surface preparation.
Easy Maintenance and Replacement: If a strip becomes damaged, it can be easily replaced without disturbing the surrounding area. This minimizes downtime and maintenance costs.
