With this view from the bottom, one can see that our solid coned (feet and/or leg) bottom design acts as a shock absorber from falls onto the surfacing below. It is also designed to help with storm water management by allowing water to flow freely in multiple directions to the drainage outlet when installed on a solid sub-base material, such as concrete (cement), asphalt (blacktop) or even rooftops. Our unique bottom-design also eliminates any “hard spots” and/or “picture framing,” a common design problem with other competing products on the market today.
