“It is unwise to pay too much, but it’s worse to pay too little.  When you pay too much you lose a little money—that is all.  When you pay too little you sometimes lose everything, because the thing you bought was incapable of doing the things it was bought to do.  The common law of business balance prohibits paying a little and getting a lot.  It can’t be done.  If you deal with the lowest bidder, it is well to add something for the risk you run, and if you do that you will have enough to pay for something better.”

More than Just Bridging the Gap: Selecting Floor Expansion Joints for Hospital and Healthcare Facilities

At Dseal, we understand that floor expansion joints in healthcare facilities must be engineered to withstand specific movements and stresses. Any failure can be unsightly, noisy, dangerous for people, and harmful to expensive medical equipment. The primary cause of damage to interior floor expansion joints and surrounding materials is the point loads from equipment fitted with hard, small-diameter wheels.

Despite the destructive impact of high point loads on healthcare floor joints, this factor is often overlooked. Many expansion joint manufacturers fail to rate the point load resistance of their products under various wheel types, making it difficult for architects, engineers, contractors, and building owners to make informed decisions.

Selection Criteria

Point load resistance is one of three critical criteria for selecting a suitably engineered floor expansion joint. Whether in new construction or retrofitting failed existing joints, consider the following questions:

Hard, plastic tires, which are most prevalent in hospitals, place the greatest stress on expansion joints. In a survey of the websites of several floor expansion joint manufacturers, only a few provided comprehensive loading data by wheel type for joint systems offered as “heavy duty” or “high point-load.” Many did not mention wheel loading capabilities at all.

Higher Point Load Stress

In hospitals, floor expansion joints often deteriorate faster than expected. This is not only due to insufficient point load capacity but also because hospital operations have been changing in ways that significantly increase point load stresses.

One such trend is “patient-centered design,” which has taken root over the past decade. The goal of patient-centered hospital care is decentralization, bringing services to the patient rather than transporting the patient to centralized locations for medical procedures. This design decreases patient movement, unnecessary staffing, waiting, and errors, allowing patients to remain in the comfort of their rooms.

However, this decentralization means more movement of equipment, as diagnostic and treatment apparatus is transported to patient rooms. This adds expensive and sensitive equipment to the already busy flow of cleaning, maintenance, and food service equipment traffic at hospitals.

Much of this equipment is conveyed by small-diameter, hard wheels, which can and do cause damage to floor expansion joints and surrounding flooring materials that are not engineered to handle the high associated point loads. Equally important is the potential damage to the equipment itself.

Another trend increasing point loads at hospitals is the need to accommodate an increasing number of overweight patients as obesity among U.S. adults has increased more than 60% during the past 20 years.

In his article “Designing for the Obese,” Dave Barista, assistant managing editor of Building Design and Construction magazine, reports the findings of interviews with leading healthcare design experts. Numerous design considerations were advocated, including “everything from wider doorways and heavy-duty beds to patient lifts.” The article also mentions that “bariatric beds should be rated for at least 600 pounds.”

Not included in this article is the impact of these design considerations on floor expansion joint selection. Oversized wheelchairs, beds, and gurneys are increasingly common in hospitals. Bariatric beds can weigh up to 800 lbs empty and, depending on the model, are rated to carry patients weighing up to 1000 lbs.

A combined load, for example, of bed and patient of 1,610 pounds, spread over four, 1-¼” (30mm) wide, hard rubber wheels, would result in a load per wheel of 402 lbs or 321 lbs per inch of wheel width.

1610 lbs = 402 lbs/wheel 402lbs/wheel = 321 lbs per inch of wheel width 4 wheels 1 ¼” wheel width

The Dseal expansion joint system intended to handle this load must be selected for its ability to handle this load without deflection. Compare, for example, the load capacity of 365 lbs per inch of wheel width of the FS 110 system.

Failure to select the appropriate Dseal expansion joint system based on this comparison could result in the specification of an inappropriate expansion joint product.

At Dseal, we are committed to providing floor expansion joints that meet the rigorous demands of healthcare facilities. Our products are designed to handle high point loads, ensuring durability and safety for both people and equipment.

Smooth Joints for hospital floor

Types of Floor Expansion Joints by Dseal

The design of floor expansion joints presents an engineering challenge. They must handle transverse horizontal opening and closing movement, longitudinal differential or shear movement, and vertical differential shear movement. These requirements are similar to the movement demands of wall, ceiling, and roof expansion joints. What makes the design of floor systems so challenging is that they must perform these movement functions while also providing a strong “bridge” that can bear point loads and provide a smooth, quiet transition for wheeled traffic, as well as a slip-free surface for pedestrians.

Manufacturers of floor expansion joints have used a variety of approaches, with varying degrees of success. The available products fall into three design categories:

Rubber and Rail Systems

The most common and least expensive system comprises two extruded-metal (usually aluminum) angles, between which an elastomeric filler is inserted or adhered. To enable expansive and compressive movement, the insert needs to be a soft, elastic material and/or shaped into a bellows form. However, soft materials and bellows shapes are incapable of resisting even relatively small point loads. Because the rubber material is soft, wheels sink in and bang against the metal angle on the far side of the joint. This results in a nasty jolt to patients and medical equipment, causes damage to the adjacent flooring, and results in early failure of the expansion joint itself.

Cover Plate Systems

To provide better point load resistance, a second product category employs a metal plate. The plate can be anchored on one side, can float between clamping plates, or can be held in the middle with a centering bar. These systems provide a stronger bridge than rubber and rail systems, and they are capable of handling small to moderate point loads, although manufacturers regularly fail to provide point load ratings from which to match models to expected traffic loads. Most of these systems are especially poor at handling floor height differences or vertical differential movement, which causes the cover plate to float unsupported at various locations. This phenomenon makes cover plates noisy, and when deformed by the torque of differential vertical movement, can result in a tripping hazard. Additionally, the gaps under the cover plates create cleaning problems, as moisture and dirt collect in the recesses—an unacceptable hygiene problem in a healthcare setting. Finally, because there is a transition on each side of the cover plate, wheels bump twice during transition over the joint.

Solid-Interlocking Systems

A purpose-designed alternative interlocks two extruded metal components in a design that accommodates horizontal opening and closing, as well as differential lateral and vertical movements, while providing high point load resistance. This solid-interlocking system was specifically designed to withstand the pounding from small-diameter, hard wheel traffic, while respecting aesthetic integration with adjacent flooring materials. The design provides a smooth, quiet rolling surface. Integrated gaskets that seal out dust and dirt are also thoughtfully engineered features for hospital environments.
