22 Sep TRAMPOLINE DAMAGE AND REPAIR – PART 1

What to do? Buy a new one or repair the damaged trampoline? In this blog post we will talk about what you should be aware of if your trampoline is damaged and how you possibly can repair it.

Trampolin mit Komplettschaden

In the following we will look at what to do if your trampoline is damaged. We will give you some good pointers on how to identify if your trampoline is damaged and what measures you can take. This post is divided into different sections where we address the trampoline components separately i.e. jumping mat, protective edge and frame.

It doesn‘t really matter which trampoline brand you have. Hudora, Royalbeach, Ampel 24 or something completely different. In this first part we are looking at: Protective edge, safety net and jumping mat.

Let‘s start with the protective edge.

 

PROTECTIVE EDGE

The material of the protective edge differs depending on the brand.

Cheap products are usually made of a polyurethane (pu) filling, which is especially flexible and dimensionably stable, but does not really withstand compressive loads. The same applies for the cover. Cheap models get easily damaged in frosty weather and seldom withstand UV-rays. This especially applies to protective edges filled with EVA (foam made of synthetic rubber).

Protective edges are usually segmented.

Now we are ready for our main topic. In the following we will address the most common damages to protective edges and what to do about it.

SPLIT SEAMS

If you have a split seam on your protective edge moisture can get inside and ruin the core fabric.

What can you do?

If you have a talent for sewing you can possibly mend it yourself with the proper equipment. You need a needle and yarn which are thick enough. If you are not able to sew the seam yourself then you should contemplate the following.

If the seam only has a minor split, it does not alter the safety or the usability of the edge. You can keep using it but you should look out for progressive deterioration. If the seam is completely split open and the filling is protruding then the edge is beyond repair.

Has the filling already shrunk, we would recommend that you replace the protective edge. Otherwise you don‘t get the proper protection. Defect padding does not withstand pressure properly.

The cover of the protective edge protects the core.

There are a couple of things to consider regardless if the elements (UV,freezing below zero) or „normal“ age related deterioration has caused the damage.

With premium quality protective edges the cover is made of polyvinyl chloride also known as PVC. PVC has a hard and rough structure which only turns into soft material by adding stabilisers. The advantage of using PVC is its longevity. Sunlight, water or air doesn‘t harm the material.

The cover of cheaper protective edges is generally made of a different kind of sythetic, which is not as resilient. Having said that, we should mention that naturally not even premium quality edges covered in PVC last forever.

What can you do?

This cannot be answered in general but depends on the individual case. If the cover is only slightly damaged and still covers the core you can look out for progressive deterioration. Small holes due to age deterioration can be sewn to protect the core. Naturally, it is up to you if you want to try and patch it up.

If the damaged area is substantial you should replace the protective edge.

In very rare cases it occurs that the filling shrinks even if the cover seems undamaged.

This is because the foam filling isn‘t UV-resistant. You will notice this because the foam will shrink. Please keep an eye on the level of shrinkage. If the core doesn‘t offer enough protection anymore you should replace the protective edge.

Has the foam gone out of shape only slightly, you can continue to use the edge but again keep an eye on progressive deterioration.

 

 

BUNGEE CORDS

There are various ways to fasten a protective edge. Mostly they get attached to the trampoline frame with wide cords.

Other manufacturers opt for bungee cords. The bungee cords are pulled through seamed eyelets on the protective edge and attached to the trampoline frame.

 

CORDS OR EYELETS GET TORN OFF

When the trampoline is exposed on a permanent basis the cords and eyelets on the protective edge may tear. Usually this doesn‘t mean that the material is of poor quality, but usually occurs due to age deterioration.

What can you do?

Again this cannot be answered in general but depends on the individual case. Torn cords can be fixed with a little skill. But if they are completely torn off skill won‘t eliminate the problem.

It is not a big issue if one or two cords are missing. You have probably experienced this yourself that when first one tears off the others usually follow suit. Thats Murphy‘s law. As long as the protective edge doesn‘t slide completely off the trampoline you don‘t neccessarily need to do anything about it yet.

Since it is quite irritating having to push the edge back into place it may at the end of the day be a good idea to replace it after all. The same goes for the eyelets. Don‘t get a new edge just because a single eyelet or two has torn off. But if too many are out of order you may consider getting the edge replaced.

Protective edges with eyelets are usually fastened with so-called bungee cords. After a while the bungee cords can lack in tension. In this case, they are unusable. If only a couple of bungee cords are affected you can replace them with cable ties. This is only a short term solution though, because they do not last very long. They are static and permanently exposed to strong vibrations. Some suppliers offer single bungee cords or a complete set of spares so you don‘t have to replace the whole thing.

 

THE WRONG SIZE

A very common way a protective edge gets damaged is if it doesn‘t fit on the trampoline.

You‘ve got a trampoline from the supermarket and bought a protective edge from a special trampoline supplier? It often doesn‘t fit a 100%. It is either too big or even worse too small. When you attach the edge and it is too small there is too much tension on it and it might tear.

What can you do?

If a larger area is torn then you should replace the protective edge. Smaller tears can be mended.

We have previously talked about damaged protective edges and what you can do.

We are progressing to safety nets. Which parts of the net easily get damaged and what you can do about it.

 

 

SAFETY NET

The safety net is made of tearproof PE-material. The durable PE has a density of around 90 – 140 g/m2 (depending on the manufacturer). A high mesh density is significant for the net‘s durability.

If your trampoline stays outside all year round the pressure on the material is very high. Especially in summer where it gets exposed to UV-rays. It can make the safety net can crumble. This can occur after a couple of years or maybe after ten. It is impossible to predict. Check your net for progressive damage on a regular basis.

HOLES

If there‘s a hole in the net it becomes unsafe to use. Please think about it carefully if you really want to risk mending it.

 

What can you do?

You hear the most harrowing stories about mending safety nets. It has for example been suggested to mend the hole with mosquito netting or sew it up with twine.

Even ordinary patches or binding the mesh together have been discussed in various forums.

Hand on your heart. Would you mend the safety belt in your car?

NO!!!

You would not! So why even contemplate mending your safety net. The risk of injury is just too great. But it is up to you, of course, if you want to give it a go.

Holes in the safety net: not only do they not look nice, but they can actually be dangerous.

CRUMBLING NET SLEEVE

There are many ways to attach the safety net to a trampoline. With some models the safety net is actually pulled over the trampoline poles.

The so-called net sleeves play a big part here. The sleeves are often made of a different material than the net itself. Mostly the sleeves are not really UV-resistant and can crumble just like the net. Maximum protection is not guaranteed anymore.

 

What can you do?

If you have experienced the problem with crumbling net sleeves, you can‘t actually do anything else but buy a new net. It is not a good idea to mend it, because the vibration caused by jumping would tear any patched up areas.

 

 

TORN LOOPS

If your safety net has loops for attachment then pose a potential damage risk as well.

What can you do?

If the loop or cord is torn directly at the seam you can try and mend it with some strong yarn and a sturdy needle. In various internet forums the use of cable ties which directly connect the net with the poles has been discussed at length.

The connecting loop itself opens with a clasp. If the clasp is defect, you can use a sturdy cord instead.

Please remember that the trampoline will be more unstable without these accessories.

It would be safer to buy a new safety net.

Most safety nets are equipped with a zip at the entrance.

A few things can happen to the zip.

 

THE ZIP IS JAMMED

It is really irritating when the zip gets jammed.

 

What can you do?

The best way to mend a jammed zip is with graphite. Pencils contain graphite. Go over the jammed zip with the pencil from top to bottom. Repeat if neccessary. You can also use graphite spray.

If this doesn‘t work you can use washing powder diluted in a little water. Rub the solution on the zip and see if it gets unstuck. Candle wax works a treat as well.

BROKEN OFF ZIP SLIDER

It is not unusual that the zip slider breaks off.

 

What can you do?

You can replace the zip slider in no time. Attach an ordinary key ring or paperclip to the bottom of the zip. Now you have something to hold on to when you are working the zip.

 

THE ZIP DOES NOT OPEN OR CLOSE COMPLETELY

Especially with older safety net models it happens that the zip does not open or close entirely.

 

What can you do?

Take some pliers and press the zip slider together. Now it will easily slide over the zip‘s teeth again. Use a little graphite for lubrication.

BUNGEE CORDS ARE WORN OUT

If you have a safety net with bungee cords, they may wear out with time.

 

What can you do?

Spend a couple of pounds on some new bungee cords. You can of course also use cable ties. But as already mentioned previously this isn‘t a permanent solution.

 

 

Now we leave the safety nets and move swiftly onto our next topic – the jumping mat

 

JUMPING MAT

 

HOLE OR TEAR IN THE JUMPING MAT

It not very often that a jumping mat gets torn, but it happens.

Maybe you thought it‘s a good idea to smoke while you‘re jumping or you can‘t be bothered to take your shoes off. All risky business which isn‘t good for your jumping mat.

 

What can you do?

It is vital for safety reasons that you replace your jumping mat if it has a hole regardless of how small it is.

In internet forums there are various discussions on on how to mend a jumping mat. They talk about mending or patching holes up. Smaller holes are portrayed as being harmless.

Please remember that the jumping mat looses its bounce when damaged.

A tear in the jumping mat can be quite dangerous. Please replace it immediately!

TORN OFF EYELETS

What can you do?

The springs are attached to the eyelets of the jumping mat. They are subjected to constant pressure and can get torn off.

A jumping mat of good quality has multiple seams which seldom tear.

If one or two eyelets are torn off the rest has to withstand the added pressure. They can only compensate for the damaged ones for a certain amount of time. Please replace your jumping mat as a safety precaution.

In internet forums there are various discussions on how to sew torn eyelets back on. It is possible but you will not get lasting results. The constant pressure and level of vibration put too much strain on the eyelets.

We really recommend that you decide to replace your jumping mat instead of trying to mend it.

Please replace it, even if only one or two eyelets are damaged.

 

THERE ARE THREADS HANING OFF THE JUMPING MAT

This is a phenonemon which you often find with new jumping mats.

 

What can you do?

Hanging threads are really annoying. You can easily just cut off the hanging threads with scissors. Don‘t cut too close to the jumping mat though.

Please also replace the jumping mat if it is threadbare.
