What is a sunken poured in place rubber flooring?
A sunken poured in place rubber surface is a section of the rubber flooring that has lost the support of the aggregate beneath usually due to draining issues leaving the rubber dependent on its tensile strength to stay in one piece. Once that tensile strength is tested by someone physically standing over it, the rubber is usually torn, revealing a void underneath it. This is a common occurrence in poured in place rubber flooring installed over a poorly compacted crushed road crush stone aggregate.
How do you fix a sunken poured in place rubber flooring?
Typically, we prefer filing the hole with something water will not dislodge, and that’s sbr buffings. When cured, poured in place base layer granules, or sbr buffings, will let water through but keep a large enough form that couldn’t be moved by the forces of water. Once the sbr buffings have cured a wear layer is mixed and troweled on top to match the other wear layer.
How do you prevent a poured in place rubber floor from sinking?
Install the rubber floor over asphalt or concrete. If you have to use stone aggregate as a base aim for 95% compaction and 1% pitch. If the area used to accumulate water you might have to install a curtain drain or other type of drainage system to channel the water correctly.
