At our local Long Branch CA public park, we had purchased Rubber Mulch from a company in New Jersey called Rubberecycle we found the site in google.com We are very pleased with the price, timely delivery and goo customer service, good deal.
We Highly recommend rubberecycle for mulch products
Andi - they also have a new material that you can actually use for basketball courts and play areas. Depending on where you plan to put this, you can actually surface an entire area with rubberized material. It's a HUGE expense, but depending on your funding, you may feel its worth it. I learned of it via the playground websites.
The World Needs Play -- Playworld Systems, Inc.
has a description of what they have on their website and then you can price compare from there.
Does anyone no where I can get the rubber mulch for a playground? I am in Texas and I can not find a website or anything that tells about this stuff. we would like to put it in our prek-k playground where the gravel is.
