Preserving History While Protecting Lives: The Art of School and Hospital Terrazzo Maintenance

In the grand hallways of historic schools and hospitals across America, terrazzo floors tell stories of decades past while serving millions of visitors daily. These beautiful, durable surfaces represent a unique challenge for facility managers: maintaining strict safety standards while preserving the architectural heritage that makes these buildings special. Ease of maintenance – is one of the principal reasons why terrazzo is found in so many buildings where traffic is heavy.

Understanding Terrazzo’s Historic Significance

Terrazzo flooring has graced institutional buildings for generations, chosen for its durability and aesthetic appeal. Terrazzo was created in Europe several hundred years ago by the Venetians who experimented with reusing marble chips by setting them in concrete. Further experiments with polishing resulted in a smooth surface for walking. Today, these floors are often protected under historic preservation guidelines, requiring specialized knowledge to maintain properly.

The Secretary of the Interior’s Standards for Rehabilitation provide a list of ten guidelines that must be met when rehabilitating a historic property for its new, modern use. Following these Standards ensures that the historic character of the property is maintained but that it will be safe and comfortable for its current inhabitants.

Safety Standards in High-Traffic Environments

Schools and hospitals present unique safety challenges due to their high foot traffic and vulnerable populations. Ground and floor surfaces along accessible routes and in accessible rooms and spaces including floors, walks, ramps, stairs, and curb ramps, shall be stable, firm, slip-resistant, and shall comply with 4.5.

The slip resistance requirements are particularly critical in these environments. These types of floors are commonly… Terrazzo has a COF of 0.64 when dry and 0.16 when wet. This significant difference between dry and wet conditions makes proper maintenance and sealing essential for safety.

Hospitals and clinics are busy environments, with patients, staff and visitors all moving in the same area. Flooring that is wet due to spills or accidents pose a serious hazard to busy staff and recovering patients. Similarly, Schools are designed to be safe spaces for kids and adults alike. However, between kids’ energy and the potential for spills and wet floors to occur, slips and falls can be a major concern.

The Maintenance Challenge

Maintaining terrazzo in historic schools and hospitals requires a delicate balance between preservation and safety. Cleaning compounds used on terrazzo should be free from alkalies, acids, or other strong ingredients which can permanently damage the floor. This restriction becomes even more critical when dealing with historic surfaces that cannot be easily replaced.

Regular terrazzo floor maintenance preserves safety as well as appearance. The maintenance schedule must account for heavy foot traffic while using preservation-appropriate methods. The cleaning cycle should be regulated by the amount of traffic. For general cleaning, use a neutral cleaning compound diluted in accordance with the manufacturer’s directions.

Professional Restoration Considerations

When maintenance isn’t sufficient, professional terrazzo floor restoration becomes necessary. This process must carefully balance historic preservation requirements with modern safety standards. Our floor restoration is a multi-step process. First, we thoroughly clean the terrazzo. Then, we use specialized equipment to grind and polish the surface, removing imperfections and restoring its original sheen. Finally, we apply a protective sealant to safeguard against future wear and tear.

The type of terrazzo affects the restoration approach. The biggest difference between types of terrazzo is the type of binder that is used. The binder, which is either a Portland cement or resinous base, serves to hold the aggregate in place. Different binders require different sealing procedures.

Compliance with Modern Standards

Historic buildings must meet current accessibility and safety requirements while maintaining their character. Application of these codes should be done in consultation with code authorities and preservation experts. A number of states have enacted rehabilitation and historic building codes that may lessen the alteration of historic material.

The Americans with Disabilities Act requires specific surface characteristics. Accessible floor and ground surfaces must be stable, firm, and slip resistant. Stable surfaces resist movement, while firm surfaces resist deformation by applied forces. Accessible surfaces must be slip resistant to minimize hazards to people with disabilities, especially those who are ambulatory or semi-ambulatory or who use canes, crutches, and other walking aids.

Best Practices for Historic Terrazzo Maintenance

Successful terrazzo maintenance in historic schools and hospitals requires several key practices:

• All cleaning solution and rinse water must be picked up, by squeegee, mop or wet-dry vacuum, to prevent slipperiness.
• Steel wool SHOULD NOT be used on terrazzo; It may rust and stain the surface.
• The occasional resealing of the terrazzo floor will protect both the floor from foreign matter and protect people from tripping and falling.
• The frequency of professional polishing depends on foot traffic and the overall condition of your floors. Generally, we recommend having your terrazzo floors polished every one to two years to maintain their luster and prevent damage.

Working with Preservation Professionals

Given the complexity of maintaining historic terrazzo while meeting safety standards, working with experienced professionals is essential. Specifications should only be applied under the guidance of a qualified preservation professional who can assess the applicability of a procedure to a particular building, project or location.

Conclusion

Maintaining terrazzo floors in historic schools and hospitals represents one of the most challenging aspects of facility management. Success requires deep understanding of both historic preservation principles and modern safety requirements. When it comes to floor safety, you can trust a terrazzo floor… However, by using an appropriate sealer, you can prevent accidents from occurring with a terrazzo floor.

The investment in proper terrazzo maintenance pays dividends in both safety and preservation. These floors, when properly maintained, can continue serving their communities for generations while meeting the highest safety standards. The key lies in partnering with professionals who understand that preserving history and protecting lives aren’t competing goals—they’re complementary responsibilities that define excellent facility stewardship.
