Seal annulus to prevent soil leaking into pipes between 6 and 8 inch pipes with neoprene or 2-inch wide foam seals wrapped around the 6" pipe or other approved method that allows the 8-inch pipe to be slid into position after tensioning. Use of slip couplings with reducers is also permitted. Seal ducts at bulkhead caps, deadmen, CRM walls and wherever terminated to prevent fill from entering annulus.
