Joint Repair

At Subsurface, Inc. we noticed early on that many pipes we lined or replaced were actually in excellent condition and had suffered no failures or defects at all!  We asked ourselves why this was happening and thought about ways to address the actual issues involved rather than applying a shotgun/band aid approach to the problem.  In addition to repairs Subsurface also traditionally installed these pipe and we knew from experience that poor installation techniques and ground movement related to outdated design parameters were the cause of these issues so we sought out the best technology to address these joint related issues” There are a lot of ways that a pipe joint can start leaking after installation.  Some of these start right at the point of installation such as; 
 
  • Incorrectly installed seals
  • Bell joints not fully seated
  • Poor grading or bedding of the pipe 
  • Improper compaction of the surrounding soil
  • Flaws in the pipes themselves 
There are also many ways that perfectly installed pipe joints can be affected over time such as;
  • Root infiltration
  • Settlement
  • Hydraulic Erosion
  • Hydrostatic Pressure (Flooding)
  • Mechanical Failure
  • Weather Impacts (i.e. Freeze Thaw Cycles)
  • Outdated Building Standards (insufficient drainage in road bed)
For many of these situations a variety of different techniques can be used to restore the pipe to Like New condition in a far more efficient and cost effective way than through the use of full lining techniques.  Some of the techniques we use include;
  • Pipe Lifting and Jacking
  • Joint Caulking
  • Joint Sealing
  • Back Grouting
  • Spot Repair Liners
