OTTO-PERFORATEDMAT

The legendary secret underneath the sand.

 

FeaturesInstallation | Tech SpecsTestimonialsFAQ

The OTTO-PerforatedMat was the very first invention of footing legend Werner Otto and it remains one of the most groundbreaking inventions in the equestrian surface sector worldwide.

Being a product specifically designed for equestrian sports, the OTTO-PerforatedMat has an enhancing effect on the safety, performance and durability of the riding surface thanks to its numerous features.

All of this has led to several millions of OTTO-PerforatedMats being installed in over 6,000 riding facilities worldwide during its 30-year history.

                

The Features

1. Clean separation of layers

Everything stays where it is supposed to – including the Mat itself.

More about the separation of layers

In riding arenas with an inadequate or no matting system, the hooves may dig up stones and other material from the subbase into the footing already after a short while.

The OTTO-PerforatedMat, however, creates a clean and durable separation between subbase (in most cases crushed stone) and footing (sand/textile blend).

This is possible by means of so-called ‘sand-locking-rings’. Due to their conic shape, neither can sand subvert the Mat nor can stones travel up into the footing. That is why the term ‘separation layer’ is often used in connection with the OTTO-PerforatedMat.

Moreover, the sand-locking-rings provide stable fixation of the Mat and prevent it from shifting.

“We have used the OTTO-PerforatedMats for 20 years. During all this time, no material from the subbase ever travelled up into the footing. Likewise, the sand doesn’t trickle down. So, this separation really works perfectly – over decades!”

2. Reliable and quick drainage

Farewell to puddles in the arena.

More about the drainage capabilities

 

Water puddles in the arena are not only annoying – many horses reject the course because of them. Moreover, muddy paddocks can lead to painful hoof diseases in the long run.

The solution: The OTTO-PerforatedMat lets any excessive water drain quickly. In combination with a suitable subbase and a water-permeable footing, this means that there will not even remain a drop of water on top of the surface.

With the OTTO-PerforatedMat, muddy paddocks and unrideable arenas become a relic of a time gone by.

A total of 252 drainage holes with a diameter of 3 cm each provide the OTTO-PerforatedMat with a total drainage area of 1,781 cm2.

Thus, almost 18% of the OTTO-PerforatedMat are responsible only for drainage.

Even after long, heavy rainfalls, the arena is immediately rideable and the horses will never have to stand in puddles or mud when they are out in the paddocks.

“Previously, we had to cover the arena up with a PVC liner before every storm. And even then, we weren’t able to ride right after the rain stopped.

But ever since we installed the OTTO-PerforatedMats, the rainwater drains instantly. Even during the ‘El-Niño’ storms with up to 180 mm of rain, we are able to ride during the storm. This has been really fantastic.”

3. Water storage

Keeps the footing moist and the money in your pocket.

More about water storage

 

Since sand is a water-bound material, the footing consistently needs to be kept in an earth-moist condition so that the horses have enough grip and no dust can be whirled up. This way, a riding surface which requires frequent irrigation can cause a high amount of time, effort and costs.

Due to a unique system of water cups on the topside of the OTTO-PerforatedMat, enough water is stored to consistently supply the footing with the needed moisture for an extended period of time.

Up to 4 liters/sqm can be stored in the Mat’s water cups. In combination with the textile content in the OTTO-ArenaTex Footing, this amounts to a total of up 10 liters/sqm of stored water.

In outdoor arenas, a large part of the manual irrigation is replaced by rainwater which can save a substantial amount of costs for tab water.

“I only water my outdoor arena twice a week because my OTTO Sport surface can store a lot of water itself. The surface is really simple to maintain and easy on the water supply.”

4. Concussion absorption

Enhancing safety, health and performance.

More about the concussion absorption

 

In equestrian sports, especially showjumping, a considerable amount of force is applied on the surface. Considering a horse’s average weight of approx. 600 kg, up to 5 tons of force may be applied on the surface when horse and rider land after a jump.

In order to prevent short-term and long-term injuries of the horse, an equestrian surface needs to be able to absorb a large part of this force.

How is this possible? – With the OTTO-PerforatedMat.

According to a scientific study by the German Association for Technical Inspection (TÜV), the OTTO-PerforatedMat absorbs more than 40% of the force applied on the surface.

This means that a large part of the force is absorbed by the surface instead of travelling back into the horses’ legs and being a considerable strain on joints, tendons and ligaments.

The build-up of layers gave in approx. 40%. (…) The above-mentioned tests showed that a cushioning effect is guaranteed when it comes to the build-up of layers already elaborated on.

5. Rebound

Ready for takeoff.

 

More about rebound

 

In addition to shock absorption, an ideal riding surface also needs to be able to elastically return a part of the applied force. This will provide the horses with increased stability and will enhance their performance.

The OTTO-PerforatedMat has been specifically engineered for this purpose.

Due to the ideal density of the recycled PVC material used to produce the OTTO-PerforatedMat, the Mat not only absorbs a large part of the force applied on it, but it also provides the horses’ legs with the optimal amount of rebound.

“During my decade-long career as showjumper, I have competed on countless different types of surfaces.

But every time I rode on OTTO Sport, a trademark of the surface was always an increased power when jumping off and accelerating.

This is one of the many reasons I chose OTTO Sport and their famous OTTO-PerforatedMats when I renewed my own surfaces at home and I have not regretted this decision once.”

6. Skid resistance

Lean back and relax … or rather lean sideways.

 

More about skid resistance

 

What if the horses accelerate, make sharp turns or stop abruptly? In these cases, the hooves need especially good grip and must not slip.

If the footing layer is applied on a flat base it will shift under the weight of the hooves. Even if the base is equipped with knobs which all have the same height, the horses will slip because, even in this case, the footing is not provided with sufficient grip and will shift, similar to an avalanche.

Thanks to a unique system of high and low knobs as well as high and low water cups on the topside of the OTTO-PerforatedMat, the footing is provided with enough stability will not shift, even when the horses make very sharp turns.

“What I really love about the OTTO-PerforatedMats is that you can just feel that the horses have more stability. Especially the horses like to go nuts and speed around, but they don’t slip and you can tell that they’re more confident. So, you really don’t have to worry about anything when it comes to safety.”

7. Temperature resistance

Sahara or Siberia – the OTTO-PerforatedMat can handle it.

More about temperature resistance

 

Countless other types of separation layers need to be interlocked or installed edge to edge.

Since every type of plastic expands and shrinks according to temperature fluctuations, this may lead to ‘wave-shaped’ arenas, since the material does not have any space to expand.

Whether torrential rainfalls, lowest-degree winters or scorching head: The OTTO-PerforatedMat maintains what it promises.

After all, millions of OTTO-PerforatedMats have been installed worldwide in various types of climates – and they work perfectly.

Since the Mats are made of high-quality recycled PVC, weather conditions cannot cause any damage to the OTTO-PerforatedMat.

During strong temperature changes, the OTTO-PerforatedMats can expand and shrink without any trouble as they are installed with a small gap between each other.

“In my training arenas at my home in Riad, the OTTO-PerforatedMats are exposed to extreme temperature fluctuations. During summer, we get up to over 50° Celsius.

But the Mats can fully handle that and everything stays where it’s supposed to be. That’s what I call ‘German Engineering’!”

8. Longevity

Do it right once – be happy forever.

More about longevity

 

Since the OTTO-PerforatedMat is produced using highest-quality material, it is extremely durable. After all, the Mats come with a guarantee of 20 years on functionality!

Even if the footing layer has to be replaced after many years, the entire base including the OTTO-PerforatedMat can be left untouched. After merely replacing the top layer, the arena will be in perfect shape, just like on its first day.

9. Easy installation

Do-it-yourself Olympic quality.

More about installation

 

Although the equestrian world is fully aware of the importance of high-quality riding arenas, the journey to get them intimidates many.

But relax! The OTTO-PerforatedMat might be one of the most proven products in equestrianism worldwide, but its installation is quite simple.

Since the OTTO-PerforatedMats do not have to be interlocked or anchored but are only laid with a small gap, they can be installed quickly and easily.

A regular skill saw, jigsaw or chainsaw can be used to cut the Mats to size, for example on the arena border. (Please wear suitable protective clothing when cutting the Mats!).

We at OTTO Sport want to make sure that the installation of your arena is carried in a worry-free way without causing any unnecessary costs.

Whether it is do-it-yourself, supervision or turnkey solution: We will adapt to your individual circumstances and needs and will help you in fulfilling your dream of an own OTTO Sport surface.

What is special about the OTTO-PerforatedMats when compared to similar systems?

By means of its numerous functions, the Mat establishes perfect elasticity and skid-resistance, saves water and ensures a clean and lasting separation between substructure and footing. Furthermore, the Mats absorb up to 40% of the hoof’s impact and rebounds it back when jumping off.

What are the dimensions and the weight of an OTTO-PerforatedMat?

The dimensions of one OTTO-PerforatedMat are approx. 117 x 85 x 5 cm, covering approx. 1 sqm. One Mat weighs 20 kg.

How many drainage holes does the OTTO-PerforatedMat have?

One OTTO-PerforatedMat has 221 holes.

How many knobs for skid-resistance does the OTTO-PerforatedMat have?

The OTTO-PerforatedMat has 426 knobs.

How many knobs for skid-resistance does the OTTO-PerforatedMat have?

The OTTO-PerforatedMat has 426 knobs.

Why does the OTTO-PerforatedMat have knobs and water cups with several heights?

To prevent the horses from skidding, a diversified surface structure is vital. A surface with an only shallow profile will not provide the footing with the needed grip. Similar to a snow avanlanche, the footing may detach from its substructure as a consequence, causing the horses to skid. The profile depth of an OTTO-PerforatedMat is very distinct due to its 426 knows and their several heights (profile depth: approx. 2,6 cm).

What material is the OTTO-PerforatedMat made of?

The OTTO-PerforatedMat is produced using elastic recycled PVC.

How are the OTTO-PerforatedMats installed?

The OTTO-PerforatedMats are installed in offset and with a gap of 3 – 5 cm. The numerous little knobs as well as water cups need to face upwards.

Can I cut the OTTO-PerforatedMats to size?

Similar to wood, the OTTO-PerforatedMat can be cut to size using a saw, e.g. bandsaw, chainsaw, jigsaw etc. Please do not use an angle grinder as the material will become too hot!

Does the OTTO-PerforatedMat have to be fixated into the ground in any way?

No. By its mere weight (approx. 20 kg) and its sand-locking-rings, the OTTO-PerforatedMat skid-resistingly stays in place and does not need to be fixated in any way.

Why are the OTTO-PerforatedMats installed with a gap?

Due to temperature fluctuations, a functioning expansion gap is absolutely vital when installing a separation layer between sand and substructure. Every material, especially synthetic, expands when exposed to heat and shrinks when it gets colder. Interlocked separating layers without a functioning expansion gap will curve upwards after some time, creating hollow spaces underneath themselves into which sand can trickle. As a result, the separating layer cannot take its initial place anymore and, with time, will be pushed upwards. The OTTO-PerforatedMats are installed with an expansion gap of 3 – 5 cm. In conunction with the sand-locking-rings, this ensures that sand cannot trickle underneath the Mats and push it upwards.

Why are the OTTO-PerforatedMats not interlocked with each other?

Due to temperature fluctuations, a functioning expansion gap is absolutely vital when installing a separation layer between sand and substructure. Every material, especially synthetic, expands when exposed to heat and shrinks when it gets colder. Interlocked separating layers without a functioning expansion gap will curve upwards after some time, creating hollow spaces underneath themselves into which sand can trickle. As a result, the separating layer cannot take its initial place anymore and, with time, will be pushed upwards.

Can the OTTO-PerforatedMats shift upwards?

No. The OTTO-PerforatedMats are installed with a gap of 3-5 cm to each other, allowing the Mats. In conjunction with the sand-locking-rings, this ensures that sand cannot trickle underneath the OTTO-PerforatedMats and push them upwards.

Why are the OTTO-PerforatedMats filled with a flitration layer during installation?

During installation, the OTTO-PerforatedMats are filled with a filtration layer to filter out possible fine parts, which may be created in the footing due to abrasion of the sand or through external components such as leaves. This way, these fine parts are kept from reaching the drainage layer and clogging it. Furthermore, the sand is cannot simply trickle into the drainage layer.

Why do the OTTO-PerforatedMats have to be installed on a slope / incline?

The OTTO-PerforatedMats have to be installed on a slope / incline to ensure proper drainge of excess water. After quickly being transported through the Mats‘ drainage holes and through the drainage layer, the water needs to be able to drain to the side. Otherwise it would ‚dam‘ inside the drainge layer. All of this is made possible by means of a slope / incline.

Which type of substructure is necessary for the OTTO-PerforatedMat?

Where necessary, the natural soil is stabilized by means of a crushed stone blend. On top of this, a drainage layer of crushed stone with a grain size of 8/16 mm and 7 cm thickness is installed, on top of which the OTTO-PerforatedMat is layed.

Can round stones be used as substructure of the OTTO-PerforatedMats?

No. Round stones should not be used as substructure underneath the OTTO-PerforatedMat. Contrary to crushed stone with a grain size of 8/16 mm, these stones do not wedge among each other. Instead, they roll and, therefore, do not give the OTTO-PerforatedMats the grip they need.

Can the OTTO-PerforatedMats be laid directly into mud?

No, the mud layer should be removed first.

Can the OTTO-PerforatedMats be laid directly on grass?

If certain requirements are met, especially for temporary installations, the OTTO-PerforatedMats could also be directly laid on mowed grass. For this purpose, a fleece liner is installed underneath the Mats.

Is a sand layer on top of the OTTO-PerforatedMats mandatory?

If the OTTO-PerforatedMats are used e. g. in a paddock, there should at least be coarse, washed sand or fine grit (grain size 2/5 mm) on top. Otherwise, the knobs on the topside of the Mats may break off.

Can the horses walk directly on top of the OTTO-PerforatedMats?

No, the Mats are not designed for the horses to tread directly on top without a footing layer.

How much sand is necessary on top of the OTTO-PerforatedMats?

A footing layer of approx. 8-10 cm, depending on the exact composition of the sand, is recommended when using the OTTO-PerforatedMats.

Can a tractor be driven on top of the OTTO-PerforatedMats?

Yes, but only when a footing layer of at least 8 cm is installed on top of the Mats and the substructure is stable.

How are the OTTO-PerforatedMats delivered?

The OTTO-PerforatedMats are delivered on one-way pallets.

How heavy is one pallet of OTTO-PerforatedMats?

One one-way pallet of OTTO-PerforatedMats contains 45 pieces with a weight of 945 kg + 20 kg for the one-way pallet (total weight = 965 kg).

Can the OTTO-PerforatedMats be moved e.g. to a new facility?

Yes. Since the OTTO-PeroforatedMats are not fixated into the ground, they can easily be removed and installed in a new arena anytime.

How are the OTTO-PerforatedMats be disposed of?

Since the OTTO-PerforatedMats are produced from recycled PVC, they fall in the category of domestic waste. However, should you, for any reason, not need the OTTO-PerforatedMat anymore, you will, normally, quickly find a buyer who will be happy to purchase your used OTTO-PerforatedMats.

Is there any warranty on the OTTO-PerforatedMats?

There is a 20 year warranty on the functionality of OTTO-PerforatedMats.

What experiences are there regarding longevity of the OTTO-PerforatedMats?

So far, millions of OTTO-PerforatedMats have been installed in thousands of equestrian facilites worldwide, where their practicability and longevity have already been tested and proven to the full. The oldest arenas installed with OTTO-PerforatedMats are approx. 25 years old!

Can the OTTO-PerforatedMats be installed in liverpools?

Yes, but in order to prevent the OTTO-PerforatedMats from floating upwards, they should be fixated on a stable surface using light concrete.
