The Propagation of a Sinkhole

The sinkhole in Fraser is capturing the attention of residents in Southeastern Michigan and across the country, many of whom are wondering how sinkholes happen and what can be done to fix them. Or better yet, what can be done to avoid them in the first place.

A sinkhole is basically any hole in the ground that is formed by erosion and drainage of water. They can be very small or as we are seeing in Fraser, they can be big enough to swallow houses, or even whole neighborhoods. Sometimes, sinkholes are the result of natural soil and rock formations, but other times they can be caused by  our aging underground infrastructure.

NTH is no stranger to dealing with sinkholes and we have been called in to work on many in Southeastern Michigan. We have won several awards for our quick response to and our innovative solutions for fixing sinkholes in the area. We have also had our engineers helping to answer questions and work on solutions for the Fraser sinkhole.

We will have a series on sinkholes within the next week to show how sinkholes such as these are formed and what NTH has done to help fix and avert sinkholes in our area. In this article, we have included illustrations that will help demonstrate how sinkholes occur. Next week we will follow up with some of our award-winning sinkhole projects.

Have you ever used "trench water" wells to identify water in the trench of the potentially leaking sewer whether storm or sanitary sewer ?
