As we became an agrarian society, farmers had to protect their grain from moisture and rotting during the cold months to prevent starvation. This Neolithic Era also brought boat-building and sea voyages into play to foment trading, so they devised a bitumen made from the surface of peat bogs, which wasn’t unlike the asphalt we use today. And then there were the Egyptians, whose Pyramids of Giza tombs were pristine despite the flooding of the nearby Nile River, so even in 3600…

PRECON For Blindside Waterproofing and Vaporproofing
PRECON goes where conventional waterproofing products are impractical – such as positive-side waterproofing where access is prohibited due to the soil retention system. PRECON fabric bonds tenaciously to poured concrete walls to create solid waterproofing protection. Superior to traditional clay-type products, PRECON features a greater seal to stop water in its tracks. A flexible, rubberized asphalt core also creates stronger protection than clay-type products currently used. The plasmatic core is a seven-layer matrix designed for toughness and provides the lowest water vapor transmission (WVT) rating on the market. Once concrete is poured against PRECON and the concrete cures, a mechanical…
