Stopping leaks to prevent erosion

Leaking stormwater or sewer pipes are often the root cause of sinkholes and less extreme depressions in surfaces. When the surface is an airport runway, stopping erosion that could lead to dips in the concrete is particularly critical. Miles of storm sewer pipes under a Midwest airport with very high groundwater were leaking, causing exfiltration, erosion and voids. A mudjacker was hired to solve the problem. He proposed chemical grouting with Prime Flex 920 instead. Read the full case study here.
