#4805 Emergency Response and Housing for the Homeless #4805 What are thin, transportable swim platforms made of Thin, transportable swim platforms generally fall into two distinct engineering designs: rigid inflatable platforms and flexible roll-up foam mats . Each relies on specific marine-grade polymers to achieve high buoyancy, tear resistance, and packability. 1. Inflatable Platforms (Drop-Stitch Docks) These platforms are typically 4 to 8 inches thick, pack down into a duffel bag when deflated, and inflate to high pressures (10–15+ PSI) so they feel nearly as solid as a wooden dock. Drop-Stitch Core: The internal cavity consists of tens of thousands of fine polyester or nylon threads connecting the top and bottom surfaces. When pressurized, these vertical threads pull taut, keeping the platform flat rather than ballooning into a round cylinder. Outer Skin: Heavy-duty, military-grade PVC (polyvinyl chloride) fabric, typically rated between 1,000 and 1,200 Denier. Most manuf...
