Our protect barrier is a great way to protect your spa investment. We build 2 pressure treated bases out of (30 year) pressure treated lumber and sandwich a piece of plastic in between creating a raised plastic bottom for your spa. This design lifts the spa off the ground like you would put a home by the ocean on stilts. It helps keep moisture away from the spa, resists mold from growing, and resists rodents from getting into the cabinet of your spa. The bottom frame is removable if necessary for service or trying to get the spa through a tight space. Some spa companies use plastic on the very bottom of the spa, but this will still allow water to get into the spa cabinet area. Our Protec Foundation allows water and moisture to flow away from your spa.
