Many owners have dams that include stone masonry walls for spillways, intakes or outlets, often in combination with earth embankments. Some are very old and include various modifications added on over decades and, in some cases over a period of 200 years or more. Many issues occur with these types of walls, including seepage though walls, displacement or misalignment of stones, partial failures and missing mortar. We are familiar with these types of problems and the correct approach to fix them for a long term solution. In addition we are able to combine the strength of a conventional concrete dam with the look old a stone laid dam.
