I'm not familar with WERM florring, but my trailer has the rumber floor which is recycled rubber.  Far superior to wood as it will last for many many years.  My trailer is a '97 and has been used a lot and the floor looks great.  Plus you don't need heavy mats that you have to pull out and clean underneath. 

    It is more expensive to put in at first, but since you don't have to replace it and it won't rot like wood floors it is much better.  I hope someone does explain the WERM floor as I would like to know what it is.

That's my concern -- that repeated pawing could damage the flooring over the life of the trailer causing the need for repair.  And then how is it repaired??  I don't currently have a pawer, but you never know. What kind of warranty typically comes with it?  Boy, it sounds great though just to hose out the trailer rather than lugging those mats in and out! I see Mr. Truck has given it a good review, but I can't seem to get to the main website for WERM today.

<<You get wear with mats too.

Very true. :-)  But this flooring is so much more expensive than mats, too. I don't know how much repairing these would be compared to buying a new mat.  So you've been happy with yours? I like what I've read so far about them, just don't know how long they'll last and how they'll really hold up.

We bought a new 4 horse C&M Norstar three year's ago and had WERM flooring put in.  WERM added about $1,000 to the price of the trailer.  We allowed ourselves one "bell's and whistles", hay rack or WERM flooring.  We didn't want to mess with mat's, so we opted for the flooring. All we do is sweep the trailer as clean as possible (stiff bristle push broom from home supply store), and take it to the car wash.  Done.  The horse area get's cleaned out more with WERM than if we had to deal with mat's.  We also have a 2 horse with mat's...no one want's to use it cause then you'd have clean it out and that's a chore. 

We've hauled the C&M about 30 time's, with from one to four horses in it. We don't have a pawer, so we don't have any noticeable wear and tear.  If it does become damaged, the damaged spot can be repaired with new product.  The surface of WERM is pebbled, like an orange skin.  The horses don't slip (we use pelleted bedding) and you can't slide a storage container on it. 

I also want to add, WERM flooring is not thin.  Not similar to truck bed liner.  It is about 3/4 to 1 inch thick.    

 No, no it's thick.  I'm sure that some people do think of it as similar to bed liner.  A horse is going to have to do some high powered pawing to get through it.  LOL 

We are two women, who would be cleaning out the trailer.  Neither of us wanted to get up close and personnel with stinky mat's.  So when they showed us the WERM, we were all over it! 

The worry I seem to have is if the urine can get around the outside where the wall meets the floor.  If it got under the WERM, wouldn't it really do a number on the floor since you cannot pull it up?  How is it sealed around those edges?

Well if you haven't figured it out yet WERM (we eliminate rubber mates) is exactually that and this product is that thick, roughly 3/4 to 1" thick. I looked into it a year ago but noone around central Iowa was at that time putting it in.

I still want to get the WERM does anyone know who does it close to Des Moines IA. (center of the state) area??? Closest I found was MPLS or KC area.

If you still have doubt's about WERM flooring, go to a dealership that offer's WERM and have a look. 

We found our info on the web.  I believe there is a way from there to locate the dealer closest to you.  We found out (by phone) there is someone considering becoming a dealer in Michigan. At any rate, there is a contact phone number on the web.
