Tactile warning surfaces are designed to be detectable underfoot or by a mobility cane. Truncated domes are commonly used where regulations or project standards require a detectable warning. Products may be manufactured from cast metal, concrete, porcelain, rubber, polymer, or composite materials. They may be embedded during construction or applied to a prepared surface. Color contrast, dome dimensions, spacing, placement, slip resistance, durability, and surrounding conditions are important. Requirements vary by jurisdiction and application. These products should be selected and installed according to the governing accessibility standards, project documents, manufacturer instructions, and local authority requirements.
