The Fall A Child Could Take Sets The Playground Depth In Milton
Rubber surfacing under play equipment is poured in two layers, and the bottom one is as deep as the fall it must catch. For a toddler climber at a Hawthorne Village daycare that may mean an inch and a half beneath the top coat. A school tower in Dempsey or Clarke might need four inches or more. The equipment's fall height decides the thickness, and your quote states it in inches.
The rubber surfacing base is black SBR, and that is the cushion. On top goes coloured EPDM, which is the wear surface. Rubber surfacing poured this way stays exactly as thick under the swings as it does at the edge, year after year.
Loose Mulch Thins Out Under The Swings And Scatters In A Halton Winter
Rubber surfacing replaces the wood chips and pea gravel that have to be raked back and topped up every season. Milton built dozens of schools, daycares and parks in twenty years of growth, and a lot of them opened with loose fill. Under the swing seats and at the slide's run-out, the fill gets kicked away, and the ground underneath is the hardest spot on the playground.
Milton's inland winter makes it worse. Freeze-thaw turns wet mulch into a frozen mat, and the spring thaw leaves it thin and muddy. Rubber surfacing drains, stays soft, does not scatter and is ready the morning after the snow melts.
What We Do On A Milton Playground Rubber Surfacing Job
Rubber surfacing for a playground goes over compacted stone, existing asphalt or a concrete pad, and we say in the quote which base your site needs. Existing loose fill is removed and the base is graded to drain. Equipment posts are wrapped so the rubber seals tight around them.
We pour the SBR cushion layer to the fall-height thickness, let it set, then trowel the EPDM top over it with the colours, borders and shapes from the drawing. Playground rubber surfacing is a bigger pour than a patio, so most school yards are three to five days, and the surface opens to kids about two days after the last trowel.
