Truncated domes are a standardized feature that can be built-in or applied to a walking surface for compliance with ADA regulations for public facilities. Truncated domes alert visually impaired people of a potentially hazardous public area such as parking or where streets intersect. Failure to comply with ADA regulations could lead to hefty fines, including a potentially costly lawsuit if a disabled person is injured in your facility.
Fortunately, there are many types of truncated domes to suit every commercial requirement, whether it’s a government project or a private business project. Ensuring you have the right expert to guide you through ensures the compliance of your facility and that you choose the right product for your needs. Here are some options when it comes to detectable warning surface products.
Cast in place non-replaceable mats
Cast-in-place truncated dome mats are usually pressed into fresh or wet concrete; hence they are used in new constructions. They are usually manufactured from exterior homogeneous glass, fiberglass reinforced composite, or carbon, making them suitable for any construction project.
The robust embodiment and the thick heavy panel ensure a solid bond to the concrete and superstructural support. They also come with a broad hard plastic sheet protection covering the whole surface of the mat, which is removed after the concrete cures. As the name suggests, they are non-replaceable; therefore, you cannot replace them once installed.
Cast-in-place replaceable mats
Cast-in-place replaceable mats are among the most preferred truncated domes by many people. They are manufactured using robust steel forming a heavy-duty anchoring system which allows for an easy installation and embodiment of the truncated dome mats into the concrete hence a faster application. The anchor system has a sleeve that cures in the concrete and a bolt that goes into the sleeve through the panel. Many manufacturers prefer to that as pre-installed.
The advantage of these cast-in-place replaceable mats is that the bolt allows easy replacement. In fact, the replacement is faster than installation. Cast-in-place truncated domes are susceptible to damage due to water and sun exposure over the years; therefore, having a replaceable option is better as it allows you to improve the aesthetics of your facility when the surface is damaged. They also have a plastic sheet covering the entire panel, removed when the concrete cures.
Surface applied truncated dome mats.
These are perfect for retrofitting into already existing concrete. They feature color-marked fasteners and structural adhesives, making them easy to install. They are durable and also easy to repair or replace when damaged.
These are curved truncated domes meant to boost the aesthetics of a facility while meeting ADA mandates. They help contractors, engineers, architects, and project managers accommodate radius scenarios successfully while complying with ADA regulations, and some of them are customized to meet the facility’s specific needs.
ADA compliance regarding the construction or layout of commercial facilities is a must. It is best to engage an ADA compliance expert to help you determine the requirements necessary for your facility to meet ADA regulations.
