Why Trailer Flooring Matters: More Than Just a Surface
When it comes to transporting horses, livestock, or equipment, the flooring in your trailer isn't just an afterthought—it's a critical safety feature. The right trailer flooring protects your animals from injury, reduces fatigue during transport, and can significantly extend the life of your trailer bed. Whether you're hauling a single horse to a local show or transporting cattle across the country, understanding your flooring options is essential.
In this comprehensive guide, we'll examine every aspect of trailer flooring: from material choices and thickness requirements to installation methods and maintenance. By the end, you'll know exactly what flooring solution will work best for your specific trailer and transport needs.
Types of Trailer Flooring: Understanding Your Options
Interlocking Rubber Mats
Interlocking rubber mats are the most popular choice for horse trailers and horseboxes in the UK. These heavy-duty mats typically measure 6ft x 4ft and feature puzzle-piece edges that lock together, creating a seamless floor surface without gaps where urine or moisture can collect.
Key benefits of interlocking mats:
- No movement during transport—the interlocking design prevents shifting
- Easy to remove for cleaning and inspection of the trailer floor beneath
- Can be trimmed to fit irregular trailer shapes
- Typically 17-18mm thick for optimal cushioning
- No adhesives required for installation
Our Horse Trailer Rubber Flooring features 18mm thick interlocking mats specifically designed for equine transport, providing the perfect balance of cushioning and stability.
Studded Rubber Rolls
Studded rubber matting—also known as penny pattern or button top—offers superior grip in wet conditions. The raised circular studs create channels for water, urine, and waste to flow away from the standing surface, keeping hooves dry and secure.
Advantages of studded flooring:
- R11 anti-slip rating for maximum traction
- Self-draining design reduces standing moisture
- Available in continuous rolls for custom fitting
- Typically 3-6mm thick—ideal for layering over existing floors
- Easy to hose clean and quick drying
For trailers requiring exceptional grip, our Horse Trailer Flooring with Studded Penny Pattern provides R11-rated non-slip performance specifically designed for equine transport safety.
Ribbed Rubber Matting
Ribbed rubber matting features parallel grooves running across or along the surface. This design channels liquids in one direction and provides excellent traction for animals loading and unloading. Ribbed mats are particularly effective on trailer ramps where grip during inclined walking is essential.
Our Broad Ribbed Rubber Matting is weatherproof and specifically suited for trailer ramps and walkways where directional grip matters most.
Solid Rubber Sheets
Plain rubber sheeting provides a simple, economical solution for utility trailers and general-purpose applications. While lacking the textured grip patterns of studded or ribbed options, solid sheets can be combined with rubber stable mats for a layered flooring system.
Trailer Flooring by Application
Horse Trailers and Horseboxes
Horses present unique flooring challenges. They're heavy (typically 450-700kg), prone to pawing and stamping when anxious, and produce significant moisture through urine and sweat. Horse trailer flooring must therefore be:
- Thick enough to cushion (minimum 17mm): Horses standing on hard floors for extended journeys can develop leg fatigue and joint stress
- Non-slip even when wet: Horses will urinate during transport, and damp conditions are inevitable
- Durable enough to resist hoof damage: Shod horses can puncture thin matting
- Easy to clean and disinfect: Biosecurity is essential when transporting horses between yards
For horseboxes and trailers, we recommend our Horsebox Floor Mats—6ft x 4ft interlocking mats at 18mm thickness, designed specifically for equine transport.
Trailer Ramps
Ramps are the most dangerous part of any horse or livestock trailer. Animals must walk up an incline while fighting gravity, often while nervous about the unfamiliar environment. Ramp flooring must provide exceptional grip to prevent slipping, which can cause serious injuries and create lasting transport anxiety.
Ramp flooring requirements:
- Maximum anti-slip rating (R11 or higher)
- Textured surface—ribbed or heavily studded patterns work best
- Must extend to the very edges with no gaps
- Secure attachment—mats must not shift under load
- Weather-resistant for external ramps exposed to rain
Our Lorry Ramp Mats provide 18mm thick interlocking rubber specifically designed for safe loading and unloading, featuring non-slip surfaces that perform even in wet conditions.
Livestock and Stock Trailers
Cattle, sheep, pigs, and other livestock have different requirements than horses. They typically travel in groups, creating more wear on flooring surfaces. Livestock trailer flooring must handle:
- Higher total weight distributed across multiple animals
- More aggressive waste and urine accumulation
- Cloven hooves that can catch in gaps or soft materials
- Potential for aggressive movement (cattle butting, pigs rooting)
Our Stock Trailer Mats are engineered for livestock applications, featuring heavy-duty 18mm rubber with interlocking edges that create a continuous floor surface with no gaps for hooves to catch.
Utility and Flatbed Trailers
General-purpose trailers transporting equipment, machinery, or materials benefit from rubber flooring for several reasons:
- Protects the trailer bed from scratches and dents
- Prevents cargo from sliding during transport
- Reduces noise and vibration
- Cushions sensitive equipment
- Creates a non-marking surface
For utility applications, our Heavy Duty Interlocking Rubber Mats provide robust protection that works equally well for equipment as for animals.
How to Choose the Right Thickness
Trailer flooring thickness directly impacts comfort, durability, and performance. Here's what to consider:
| Thickness | Best For | Key Characteristics |
|---|---|---|
| 3-6mm | Utility trailers, secondary layer over existing mats, ramp covers | Lightweight, easy to handle, provides grip but minimal cushioning |
| 10-12mm | Sheep/goat trailers, short journeys, smaller livestock | Moderate cushioning, good for lighter animals |
| 17-18mm | Horse trailers, cattle trailers, long-distance transport | Optimal cushioning for large animals, fatigue reduction, joint protection |
| 20mm+ | Recovery trailers, competition horses, premium applications | Maximum comfort, vibration dampening, suitable for nervous or valuable animals |
For most horse trailer applications, 17-18mm is the industry standard. This thickness provides adequate cushioning for journeys of any length while remaining light enough to handle during installation and cleaning.
Installation Guide: Fitting Trailer Flooring Correctly
Step 1: Prepare the Trailer Bed
Before installing new flooring, the existing trailer floor must be thoroughly prepared:
- Remove all existing mats and dispose of degraded material
- Inspect the trailer bed for rust, rot (in wooden floors), or structural damage
- Repair any damage—holes, soft spots, or corroded areas must be fixed before covering
- Clean thoroughly—remove all debris, old adhesive residue, and dried waste
- Allow to dry completely—moisture trapped under mats accelerates corrosion
- Apply rust-preventative treatment to metal floors if appropriate
Step 2: Measure and Plan Your Layout
Accurate measurement ensures minimal cutting and optimal mat placement:
- Measure the trailer interior at its widest and longest points
- Account for wheel arches, tie rings, partitions, and other obstructions
- Plan mat orientation—typically mats run front-to-back for easiest installation
- Calculate how many mats you need plus 10% for cutting and waste
Step 3: Install Interlocking Mats
For interlocking rubber mats:
- Start at the front of the trailer and work backward
- Engage the interlocking edges firmly—a rubber mallet helps seat connections
- Cut edge pieces to fit using a sharp utility knife (a fresh blade makes cleaner cuts)
- Leave a small expansion gap (5-10mm) at the walls—rubber expands with temperature
- No adhesive is typically required—weight and interlocking hold mats in place
Step 4: Install Rubber Roll Flooring
For continuous roll matting:
- Unroll the matting and allow it to acclimatise to ambient temperature (ideally 24 hours)
- Position the roll and mark cutting lines
- Cut slightly oversized, then trim to fit precisely
- Adhesive may be required for thin roll materials—use a rubber-compatible contact adhesive
- Work from one end to avoid trapping air bubbles
- Roll firmly with a floor roller to ensure full contact
Maintenance and Cleaning
Regular Cleaning (After Each Use)
Proper maintenance extends flooring life and maintains hygiene:
- Remove loose debris—sweep out droppings, bedding, and hay
- Hose down with clean water, allowing waste to drain
- Disinfect weekly using an animal-safe product
- Allow to dry before reloading—damp mats under bedding can develop mould
Deep Cleaning (Monthly)
Monthly deep cleans prevent buildup and allow inspection:
- Remove all mats from the trailer
- Inspect the trailer floor beneath for rust, rot, or damage
- Pressure wash mats on both sides
- Treat the trailer bed with appropriate sealant or rust inhibitor
- Allow everything to dry completely before reinstalling
Signs Your Flooring Needs Replacing
Rubber flooring doesn't last forever. Watch for these warning signs:
- Visible holes, tears, or worn-through spots
- Hardening or cracking of the rubber surface
- Loss of anti-slip texture—smooth areas indicate wear
- Deformation—permanent compression marks or uneven surfaces
- Persistent odour that cleaning won't remove
- Interlocking edges that no longer connect securely
Most quality rubber trailer mats last 5-10 years with proper care. However, heavy use, inadequate cleaning, or extreme temperatures can shorten lifespan.
Common Trailer Flooring Problems and Solutions
Problem: Mats Shifting During Transport
Causes: Mats too thin, interlocking not fully engaged, floor surface too smooth
Solutions:
- Upgrade to thicker, heavier mats (18mm minimum)
- Ensure all interlocking edges are fully seated
- Consider adhesive application for persistent movement
- Add rubber strips along walls to prevent edge lift
Problem: Water Pooling Under Mats
Causes: Poor drainage, blocked drain holes, mats lying flat without channels
Solutions:
- Use studded or ribbed mats that create drainage channels
- Ensure trailer drain holes are clear and functional
- Raise mats slightly at drain points to encourage flow
- Remove and dry mats regularly
Problem: Rubber Developing Odour
Causes: Urine absorption, insufficient cleaning, inadequate drying
Solutions:
- Clean more frequently with enzymatic cleaners
- Allow complete drying between uses
- Replace mats if odour persists after deep cleaning
- Consider closed-cell rubber that resists absorption
Legal and Insurance Considerations
In the UK, trailer flooring falls under animal transport welfare regulations. The Welfare of Animals (Transport) (England) Order 2006 requires that:
- Floors must be constructed and maintained to minimise the risk of injury
- Surfaces must not be slippery
- Floors must be able to withstand the weight of animals transported
- Adequate bedding or equivalent must be provided (rubber matting can fulfil this requirement)
Failure to maintain safe trailer flooring can result in animal welfare prosecutions and insurance claim rejections if an injury occurs. Keep records of flooring maintenance and replacement dates.
Frequently Asked Questions
How thick should horse trailer flooring be?
Horse trailer flooring should be at least 17-18mm thick. This provides adequate cushioning for joint protection during transport, sufficient durability to resist hoof damage, and proper insulation from cold metal trailer beds. Thinner mats (under 15mm) don't provide enough shock absorption for horses standing during long journeys.
Do I need to glue down trailer mats?
Interlocking rubber mats typically don't require adhesive—their weight and interlocking design keep them in place. However, thin roll matting (under 6mm) and ramp coverings often benefit from adhesive application. Use only rubber-compatible contact adhesive, and ensure surfaces are clean and dry before application.
Can I use gym mats in my horse trailer?
We don't recommend using gym mats in horse trailers. While they may look similar, gym mats aren't designed for animal urine exposure, lack the anti-slip ratings needed for safe transport, and may not withstand the weight and hoof action of horses. Always use mats specifically designed for equine transport applications.
How often should I replace trailer flooring?
Quality rubber trailer flooring typically lasts 5-10 years with proper maintenance. Replace mats sooner if you notice holes, cracks, permanent compression, loss of anti-slip texture, or persistent odours that cleaning won't remove. Inspect flooring thoroughly at least twice yearly.
What's the best flooring for a trailer ramp?
Trailer ramps require maximum grip, so ribbed or heavily studded rubber matting is best. Look for R11-rated anti-slip surfaces that perform even when wet. The matting should extend to the very edges of the ramp with no gaps, and must be securely attached to prevent shifting during loading.
Is rubber flooring better than aluminium for horse trailers?
Yes, rubber flooring is significantly better than bare aluminium for horse trailers. Aluminium is slippery, cold, noisy, and offers no cushioning. Rubber mats provide anti-slip traction, thermal insulation, noise reduction, and joint-protecting cushioning. Even trailers with aluminium floors should have rubber mats installed over the metal surface.
Can I cut rubber trailer mats to fit?
Yes, rubber trailer mats can be cut to fit around wheel arches, partitions, and other obstacles. Use a sharp utility knife with a fresh blade for cleanest results. Mark your cutting line with chalk, and cut from the smooth (back) side of the mat where possible. Make multiple passes rather than trying to cut through in one stroke.
Do I still need bedding with rubber trailer mats?
This depends on journey length and personal preference. For short journeys (under 2 hours), thick rubber mats (18mm+) alone can be sufficient. For longer journeys, adding a thin layer of bedding (shavings or straw) provides additional comfort and absorbs urine. Some horse owners prefer bedding for all journeys to encourage horses to urinate in transit.
What's the difference between horse trailer mats and stable mats?
While similar in construction, trailer mats are typically lighter for easier handling, feature more aggressive anti-slip patterns for transport conditions, and are designed to withstand the movement and vibration of travel. Stable mats can be used in trailers, but purpose-designed trailer mats offer optimised performance for transport applications.
How do I stop rubber mats from sliding on trailer ramps?
Secure ramp mats using rubber-compatible adhesive, aluminium strips screwed along the edges, or interlocking mats specifically designed for ramps. Never rely solely on gravity or friction for ramp flooring—a shifting mat during loading can cause serious injury. Check ramp mat security before every journey.
Can rubber trailer mats be recycled?
Yes, rubber trailer mats can often be recycled. Many are made from recycled tyres and can be reprocessed at their end of life. Contact local recycling centres or specialist rubber recyclers. Alternatively, old mats in reasonable condition can be repurposed for garage flooring, garden paths, or workshop surfaces.
What weight can rubber trailer mats support?
Quality rubber trailer mats support weights well exceeding typical animal loads. Standard 18mm interlocking mats handle horses up to 800kg without issue. For cattle trailers carrying multiple animals totalling several tonnes, the limiting factor is the trailer floor itself, not the rubber mats. Ensure your trailer bed can support the total load.
Are rubber trailer mats resistant to urine?
Quality rubber mats are resistant to urine and won't break down from exposure. However, urine can pool in textured surfaces and seep between mats over time. Use interlocking mats to minimise gaps, clean regularly with enzymatic cleaners, and ensure mats dry completely between uses to prevent odour buildup.
How much does trailer flooring cost in the UK?
Trailer flooring in the UK typically costs £15-40 per square metre depending on thickness and quality. A standard two-horse trailer (approximately 4-5 sqm floor area) costs £80-200 to floor completely. Premium interlocking mats cost more initially but offer better value long-term through durability and reduced maintenance.
Should trailer mats be smooth or textured?
Trailer mats should be textured for safety. Smooth rubber becomes dangerously slippery when wet—exactly the conditions encountered in animal transport. Studded, ribbed, or hammertop textures provide essential grip. The underside can be smooth for stable contact with the trailer floor, but the top surface must provide traction.
Conclusion: Invest in Safety
Trailer flooring is one of the most important investments you'll make in animal transport safety.
