Surface depressions and sinkholes forming near storm drain inlets, along pipe routes, or near manhole rings indicate that void formation is occurring underground — caused by water infiltrating through failed pipe joints carrying fine soil particles with it. The void grows with every storm event until the surface can no longer support it.

Sinkhole formation near storm drains follows a predictable progression — starting with pipe joint failure and ending with surface collapse if the failed joint is not rehabilitated.
Once void formation is confirmed above a failed storm drain joint, the rate of void growth accelerates — each storm event removes more material, and the cost and complexity of remediation increases with void size.
Sinkhole formation near storm drains is most common where pipe joint failure occurs in granular soils — where fine-particle transport is most efficient.
A Charlotte church property had developed a sinkhole approximately 4 feet in diameter near a storm drain inlet in the main parking lot — forming over approximately one storm season. Camera inspection found significant joint separation at two locations in the storm drain run beneath the affected parking lot area.
LiningWorks CIPP-lined the storm drain run through existing manhole and inlet access, sealing both identified joint separation locations. Surface pressure grouting through the parking lot surface filled the void. Post-installation camera confirmed full liner bond at both previously failed joints. No further surface movement has occurred.
“4-foot sinkhole in the parking lot near the storm drain inlet. Camera found two failed joints underneath. LiningWorks lined the pipe through existing access, we grouted the void from the surface, and the parking lot is solid. No excavation, no pavement replacement.”

We had a plumbing emergency around the holiday's and called a local plumbing company. They cleared the line and quoted a pretty high price to dig up my yard and fix the damaged sewer line. The next day I found LiningWorks online and called Jeremiah. He was very helpful and confident they could fix my sewer line without digging. Seemed too good to be true. The lining has been installed, yard not damaged and looks to have resolved the break. Jeremiah even offered to come back and scope it at a later time to ensure it's all good. Highly recommend Lining Works for any situation where you can't or don't want to dig. Thanks guys!
LiningWorks was top notch. We had a sewer main that got damaged and was completely blocked up. They were able to clear the drain, remove all issues, and reline the entire sewer main without cutting out my driveway and yard. And they were able to get the job done in one day. I would and plan to do business these guys again in the future and would highly recommend them to others.
Where do I begin? Let's just say I had an absolute nightmare on my hands for about 5 years with my sewage. I had one company quote me 7k after he snaked my sewage line and from there I just kept snaking it every year. I dreaded the oncoming financial disaster but I bit the bullet and called LiningWorks. BEST home decision of 5 years. Jeremiah came out and tackled this chaos with grace and integrity. He got down to the root of it — after years of money, anxiety, and frustration he found out it was a city problem! I will definitely be calling LiningWorks when my lining needs replacing. Call them now, you will not be disappointed.
Hired them to redo the pipes at my home because they were old. They were very polite, answered all my questions thoroughly and did an AMAZING job. Jeremiah was the very best that I could ask for and highly recommend his services. Extremely satisfied with the work done. Thanks again Jeremiah!
I am very happy with the work that was done and the clean up after the job was done. Jeremiah and Ralph are very professional and skilled in their craft. I received an estimate and the job did exceed the original estimate. I contacted them about it and they were very understanding and explained why.
Lining Works was excellent to work with. They were perfectly professional. They were organized, efficient, and friendly throughout the whole process. They took time to answer all of our questions. Pipe lining is an incredible option and the team at Lining Works couldn't have been better. They were also transparent, honest, and consistent with their cost/pricing. We couldn't be happier. We feel very fortunate that we found Lining Works. Great guys!
The main drain line in our airbnb kept clogging up, filling the house with an awful sewage smell. We had drain cleaners come out to clear the line every couple months but it finally got so bad we had to close off our bookings. LiningWorks were very prompt in coming out. We discovered tree roots had broken up our line. Our sewage line runs under a tree and 6ft deep through our crawlspace so digging it up was going to be a nightmare. Liningworks was able to cut the tree roots out and line the pipe without any digging so that it's as good as new. Would definitely recommend them to anyone needing sewage line repair.
Lining Works responded to my request quickly and fixed my drain problem very fast. I would highly recommend you give them a call.
Sinkhole formation near storm drains starts with pipe joint failure. Rehabilitating the pipe stops the void growth mechanism — then surface grouting addresses the existing void.
Camera locates the failed joints — CIPP seals them before the void grows larger.
336-477-3218, Mon–Sat 7AM–6PM. Sinkhole size, proximity to drain inlets, timeline of development — describe what you're seeing and we'll assess urgency and schedule the camera assessment.
We scope the storm drain system beneath the sinkhole area, identify all failed joints, and develop a CIPP lining scope that covers all void-generating infiltration sources.
CIPP liner through existing access seals all identified failed joints. Post-installation camera confirms full liner bond. Surface pressure grouting fills the existing void without excavation.
