What is the best relining product for your job?

 

There are many different pipe relining products on the market. Each one is better suited to certain situations. Because of this, we do not use a one size fits all method when choosing a product for a certain job. We have not purchased a relining franchise so we are not tied to a particular product.

 

If a more structural repair is required, which needs to be engineer designed to achieve certain strengths, then a fiberglass repair product is a better choice. If ground movement is present, then a more flexible felt is probably a better choice.

A few points that need to be investigated prior to choosing a lining product are as follows:

 

  1. Does the repair need to achieve a certain strength rating i.e. engineer design?
  2. Is ground movement present?
  3. What is the depth of pipe to be repaired?
  4. What is the condition of the host pipe? Are there any cracks or fractures?
  5. Does the pipe need robotic cutting to enable full flow or to remove any defects (a liner only takes the shape of the host pipe)?
  6. What type of resin should be used (this changes curing / hardening times and strengths etc.)?
  7. Does the host pipe have a large hole in it which will require extra bracing?
  8. Is there water leaking into the pipe (infiltration)
  9. Is the repair required on a straight pipe, bend or junction?
  10. Is maintaining minimal restriction on internal pipe size necessary? This effects the end result in terms of line thickness.
  11. What is the pipe to be repaired used for?
  12. Where are the access points to carry out the work?
  13. Is flow control required? This includes bypass work or a shutdown of the system.
  14. Are the tree roots small or large and aggressive?
  15. Is a sectional repair or a complete reline best?

 

As you can see, it is important to choose the correct product for the job along with the correct installer.
