Effective disinfecting protocols depend on stall materials, a detail that can lead to six-figure losses. A single EHV-1 outbreak cost one facility €151,000, mostly from business closure, not medication. Porous wood absorbs pathogens, making complete sterilization impossible and putting the entire operation at financial risk.

This analysis defines the clinical standard for biosecurity. We examine the material specifications, from non-porous, 28-32mm HDPE infill to hot-dip galvanized steel frames. These materials are essential for the low-pressure washing techniques and facility designs that ensure true pathogen containment.

The Cost of a Barn Outbreak (Strangles/EHV-1)

A serious barn outbreak like EHV-1 can easily cost a facility over €150,000. The biggest financial hit is not vet bills but loss of revenue, which can account for more than half the total cost.

Direct and Indirect Financial Impacts

When an infectious disease hits, most people focus on medication costs. That’s a mistake. The real damage comes from shutting down your business. One documented EHV-1 outbreak at a European equine hospital totaled €151,000. The largest portion of that bill—over 50%—was lost revenue from clinic closures and negative publicity.

The costs break down in ways many facility managers don’t anticipate. Beyond the obvious vet bills, the expenses stack up quickly. Here’s what that €151,000 bill actually looked like:

• Loss of Revenue: €76,805
• Stabling Costs (temporary): €31,896
• Quarantine Materials: €26,887
• Staffing & Public Relations: €10,806
• Medication: €4,606

As you can see, the medication was the smallest part of the financial disaster. The operational chaos—extra staffing, PR to manage client panic, and setting up quarantine zones—drives the cost. The financial bleeding from being unable to operate normally is what cripples a business.

Material Choices for Effective Quarantine Units

Controlling an outbreak requires effective isolation, and that comes down to the materials you use for your quarantine stalls. Wood is a major liability. Its porous surface acts like a sponge for bacteria and viruses. You can’t truly disinfect it because pathogens get deep into the material where chemicals can’t reach.

This is why non-porous materials are the standard for any serious biosecurity setup. A smooth, sealed surface can be properly cleaned and disinfected, breaking the chain of transmission. HDPE (High-Density Polyethylene) is the ideal material for this application. It’s completely non-porous, impact-absorbing, and requires zero maintenance.

Our DB Stable Economy Series was engineered specifically for these high-risk environments. It combines a hot-dip galvanized steel frame with HDPE infill, creating a stall that can be rigorously disinfected day after day without degrading. It provides a kick-proof, safe environment that also protects the rest of your facility from cross-contamination.

Porous vs. Non-Porous: Why You Can’t Disinfect Wood

Wood’s porous fibers absorb and shield pathogens from disinfectants, making sanitation impossible. Non-porous materials like HDPE allow for complete, effective surface cleaning for biosecurity.

How Porosity Traps Pathogens

Wood isn’t a solid surface. It’s a network of microscopic channels and voids. These natural pores act like a sponge, allowing bacteria, viruses, and organic matter to soak deep below the surface where they are safe from cleaning protocols.

Once pathogens get inside these fibers, standard disinfectants and cleaning methods can’t reach them. You can scrub the surface all you want, but the contamination remains shielded within the wood itself. This makes achieving a truly sanitary state impossible.

The problem gets worse with moisture. Wood absorbs water, which creates the perfect breeding ground for mold and bacteria to multiply inside the material. Any attempt at cleaning can actually feed the problem by adding more moisture.

HDPE: The Non-Porous Material Solution

High-Density Polyethylene (HDPE) is the engineered solution to this problem. At DB Stable, we use 28mm-32mm thick HDPE infill because it is a completely solid, non-porous material. There are no channels, no voids, and no places for pathogens to hide.

When you apply disinfectant to an HDPE surface, it makes full contact with everything on that surface. Bacteria and viruses have nowhere to escape, ensuring they are neutralized effectively every time you clean. The material itself doesn’t absorb moisture, so it won’t support mold or mildew growth.

This non-porous property is the reason HDPE is the core of our ‘Zero Maintenance’ stall walls. It provides a reliable, cleanable surface that is essential for any facility with strict biosecurity protocols, especially in quarantine units or clinical veterinary settings.

The Pressure Washing Protocol for Isolation Stalls

Effective stall decontamination requires low-pressure washing to avoid spreading pathogens. The process hinges on non-porous materials like HDPE, as porous wood harbors bacteria and compromises safety.

The Low-Pressure Decontamination Method

The goal is to clean thoroughly without making pathogens airborne. High-pressure systems create a fine mist of contaminated water, spreading disease rather than containing it. The accepted method is systematic and focuses on containment.

• First, you must manually remove all organic material. Scrape out all manure and old bedding. This step gets rid of the bulk bioburden before water is even introduced.
• Next, use a low-pressure water system with a good detergent to wash every surface. The soap helps break down biofilms, and the low pressure ensures you aren’t aerosolizing viruses and bacteria into the air.
• Finally, let the stall dry completely. Any remaining moisture can dilute and neutralize disinfectants, rendering the final step useless. Pathogens thrive in dampness, so a bone-dry surface is critical.

The Advantage of Non-Porous HDPE Infill

The cleaning protocol is only as effective as the material you’re cleaning. Wood is porous; its microscopic channels absorb moisture and organic matter, creating a permanent sanctuary for pathogens that no surface disinfectant can reach. This makes wood a significant biosecurity liability in a quarantine setting. HDPE provides a solid, non-porous surface where pathogens have nowhere to hide.

Our HDPE infill is engineered for “Zero Maintenance” because it withstands repeated exposure to water, detergents, and chemical disinfectants without breaking down. Unlike wood, it won’t rot, splinter, or absorb chemicals that could harm an animal later. It’s a stable, inert material designed for the harsh reality of clinical cleaning cycles.

This is why our Economy Series stalls, designed specifically for quarantine and isolation units, use HDPE infill. The material ensures that the stall can be sanitized effectively and reliably, time after time, protecting both the animals and the facility’s operational integrity.

Designing a Quarantine Block: Separate Airflow and Drainage

A true quarantine block needs completely independent airflow and drainage for each stall. This design stops pathogen spread through shared ducts or plumbing, a common failure point in barns.

The Principle of Independent Air and Waste Pathways

Standard barn construction often connects stalls through shared drainage stacks and ventilation systems. This is a massive biosecurity risk. A simple flush in one stall can create pressure changes in the plumbing, pushing infectious aerosols through the pipes and into an adjacent stall. Any connection is a potential pathway for contamination.

The only reliable solution is complete separation. Each quarantine unit must have its own dedicated ventilation system. This system should be engineered for negative pressure, ensuring air flows into the stall and is then exhausted directly outside. This design prevents contaminated air from ever recirculating into common areas or other stalls.

Materials and Ventilation in DB Stable’s Quarantine Setup

The mechanical systems are only half the battle; the materials inside the stall must also support biosecurity. Our Economy Series is specifically configured for these demanding quarantine and isolation roles. A core feature is its non-porous HDPE infill. Unlike wood, which harbors pathogens in its pores, HDPE can withstand repeated, harsh chemical disinfection cycles without degrading or absorbing contaminants.

The standard open-top grill design of this series also contributes to a safer environment. It promotes a natural airflow pattern known as “Stack Effect Ventilation.” As warmer, contaminated air rises within the stall, the open grill allows it to be continuously pulled up and out, complementing the mechanical exhaust system and improving overall air quality.

The DB “Clinical Grade” HDPE Setup

A “Clinical Grade” setup uses non-porous, 28-32mm thick, UV-stabilized HDPE planks instead of wood. This material stops bacteria and viruses from absorbing, allowing effective high-pressure disinfection for quarantine stalls.

Why Non-Porous Surfaces are Essential for Biosecurity

Traditional wood stalls present a major biosecurity risk. Wood is porous, so it naturally absorbs moisture, urine, and organic matter. This creates an environment where bacteria and viruses can penetrate deep into the material, sheltering them from surface-level cleaning and disinfection. Once pathogens are embedded in the wood’s microscopic channels, you can’t get them out.

Non-porous surfaces are the only way to achieve true disinfection. Materials like High-Density Polyethylene (HDPE) have a solid composition that prevents pathogens from getting a foothold. Any contaminants stay on the surface, where standard cleaning and disinfecting protocols can effectively remove them. This is the fundamental requirement for any serious quarantine or clinical environment.
