Optimum Cell Wall / Infill Interface BENEFITS OF PERFORATIONS: Friction 20’ Increased frictional interlock between the aggregate infill and cell wall Greater resistance to upward displacement caused by freeze/thaw cycles. Facilitates lateral drainage of excessive 8’ ground and surface water. BENEFITS OF TEXTURED Allows lateral cell-to-cell drainage beneath CELL: traffic areas. Textured Increased frictional interlock Cell Wall Allows concrete infill to flow through the cells, between the aggregate infill increasing the frictional resistance between Unexpanded Section WALL SECTION the concrete and cell walls 2’ x 4’ X 8” and cell wall PRESTO ANCHORING PRESTO ANCHORING PRESTO TENDONSTENDONS TA ClipATRA® TA StakeATRA®

KEENE VALLEY (AP) — A new report by The Nature Conservancy projects a decrease in lake trout habitat in the Adirondacks due to increasing water temperatures, fertilizer runoff and competition from non-native species like bass and pike. The report released Monday by the organization's Adirondack chapter provides a baseline reference on the region's lake trout population and recommendations for communities and landowners to guard the long- term water quality of their lake-trout lakes. The report says lake trout no longer inhabit 74 Adirondack lakes with a historical record of the species. It suggests a follow-up study to evaluate the long-range viability of the 102 known Adirondack lake trout waters. Lake trout have the most demanding temperature and oxygen requirements of New York's game fish. Water must be very cold and highly oxygenated.
