But wouldn’t that end up being a really hard surface that wouldn’t be very nice for them to stand on?
I’ve never seen it done any other way so I think it’s fine. The Ag lime on top will get soft when it gets wet.
Pea gravel doesn’t have any stability to form a stable surface. It will roll underfoot and will work into the ground.
No, not at all. But it is/was buried under 6 inches of aggregate. I do see after these years that I need a fresh layer and get another roller. I do see the value of ongoing maintence to keep the pad in great shape.
I’ll dig up the old threads tonight when I’m home. I’ve got a dry lot file oh yes I do.
And is exhausting to try to walk on.
Scrape off and stock pile topsoil
Grade dry lot area to drain - 2% side slope
put directional ditch/and or berm at top and bottom of dry lot and - can be wide and shallow. Cover with salvaged top soil. Let gravity be your friend and keep outside water from getting into your dry area, and when it does, let it flow out.
Place 4 inches of 2 inch rock. Its large and angled and will lock together, and not sink. Top with 4 inches of 3/4 gravel. It will filter down into the crevasses and holes of the bigger rock and smooth the top surface.
Water will permeate through the layers of gravel and rock, hit the sloped grade below and drain away.

And here’s a note I made from someone who said they made park trails. Their advice:
The way around spending money on gravel each year is to put down filter fabric first. Grade the area to create drainage, put down the fabric, put down drain rock, and apply a top layer either limestone fines or gravel depending on use. We built roads, parking areas, round pens, and paddocks this way and never once had to add additional gravel. The oldest areas are about 15 yrs old now.
One more!
If it drys out for a period of time it gets hard but not like concrete. During periods of wet it gets softer, almost too soft.
Agree here - it gets no harder than a packed dirt road IME.
Pea gravel is a real B to get a wheelbarrow through or even to walk on (and you’ll need to do both to pick poo up to keep it from turning into mud). The previous owners of our place had the barn floor as pea gravel, probably because the floor is so uneven, and the first thing we did was tear it all out and it was miserable.
I’m in the PNW also. One of the barns I boarded at had pea gravel paddocks - and they worked. They leveled the ground. They put down fabric - you need to get ‘road fabric’, or heavy duty nursery fabric, which you can source at OBC NW. They have it in giant rolls, not that little 3’ stuff that rips when you look at it… lol. Anyway, level the surface, put the fabric down, and put about 8" of pea gravel on it. It worked. It had been in place for years with little upkeep other than picking poo. Other areas of the farm had ‘pads’ where they put down the fabric, put down railroad ties, and filled with 1/4" minus or scalpings. It packed and drained and stayed mud-free.
The #1 problem I see with people trying to make ‘mud free’ in the PNW is they don’t address the drainage, the #2 problem is they don’t put down enough topping.
What I’d add about keeping a dry lot free of organic material is surface really matters. The limestone topping is easy to rake and use a pitchfork. My horses gift me with doing all manure out on the drylot
versus their open stalls.
After our winter deepfreeze then buckets of rain I had lots of debris - hay etc and bit rake cleaned
it up fast and then saw the drylot tighten right back up. Pretty interesting.
Limestone… Is there a particular reason why limestone is specified in a lot of these comments? It’s not that available near me. And isn’t it on the soft or dissolvable side? What qualities does it have that makes it specified? Are there reasonable substitutes?
In my area limestone is crazy cheap and packs down hard yet drains really well.
It’s 1/2 the price of crushed bluestone.
That really depends on the specific area where it’s mined. Mine here is super hard, has a high iron content.
I had my excavator over to talk about my plans to build/start a track around my property and he said the fabric down is a huge factor in the surface holding up over the years.
Good question about limestone versus something else.
we use decomposed granite, it is less dusty
And that comes out of agg pits too?
The problem with limestone is that it’s basic nature can irritate the skin, usually on the pasterns, and create open lesions which can get infected. “Limestone poisoning”.
Pretty sure that’s only hydrated lime, not the untreated stone and aglime/barnlime we use on roads and in barns. My MSDS on my material doesn’t list any burn hazards…
ETA - Just pulled it up and the only skin concern is if they’re sliding across it and doing actual mechanical damage - “Not known to be a dermal irritant or sensitizer” is the exact wording.
Yes, it is when there is a lesion/cut/injury from something else that it can become a problem. A horse I raised and sold died/was put down from this. A small cut incurred during a race at a track where this was a known problem, due to the limestone under the track surface which got kicked up with the cushion during a race, small cut on the suspensory ligament. I don’t know how deep, I wasn’t there, heard about it after the fact. Ate right through to the ligament itself, resulting in euthanasia. The track was famous for exactly this problem, it happened quite often. Not a racetrack that I ever ran horses at.
