What is Pipe Re-Rounding?


Pipe re-rounding is a process that involves rehabilitating and re-lining an existing pipe. It is a trenchless technology with minimal disruption and is usually less expensive than laying a new pipe. The process can be performed on pipes ranging from 100mm to 450mm. It requires that the pipe be shut off so the technicians can work.

Re-Rounding a Dented PVC Pipe

If you have a dented PVC pipe, you can take some easy steps to fix the damage. You can apply duct tape and tighten it with a hose clamp for smaller holes. This temporary fix should hold until a plumber arrives.

The first step in dented pipe re-rounding is to remove the material that has been clogging the pipe. The next step is to insert the pipe into a fitting and cement the connection. The process takes less than an hour and can be completed without causing any damage to the surrounding property.

Depending on the dent’s severity, you can apply fiberglass resin cloth to the dent. Make sure to follow the manufacturer’s directions and make sure to wrap the pipe tightly. The fiberglass wrap will have the best adhesion if the pipe is clean and debris-free. Before applying the fiberglass wrap, you must clean the pipe to ensure the material sticks well.

Maintaining Pipe Roundness

Pipe re-rounding is a process that restores roundness to older pitch pipes. It uses trenchless technology to cause minimal disruption and is cheaper than laying new pipes. It can be performed on pipes from 100mm to 450mm in diameter. During the re-rounding process, the flow must be diverted.

Re-rounding clamps are available in diameters ranging from 16mm to 710mm. Using these clamps on PE pipe before electrofusion welding allows the pipe to return to its original round shape. When used correctly, these tools are effective in ensuring roundness and preventing pipe kinking and splitting.

Providing Soil Compaction

Soil compaction is a key consideration for infiltration best management practices. This approach helps prevent runoff and provides stability and strength to soils. However, compaction of soils during construction and pipe re-rounding is sometimes unintentional and can lead to issues. 

Compaction is essential to the construction industry—compaction of soil results in various engineering properties, such as stiffness and modulus. Current methods for measuring these properties are labor-intensive, dangerous, and have variable accuracy. As a result, construction sites are often under-sampled. As a result, adequate compaction may go undetected, and feedback may come too late to correct the problem. Additionally, a lack of reliable and accurate compaction measurement can lead to over-specifying projects.

Soil compaction has several environmental effects, from reduced water infiltration to reduced drainage. Generally, compacted soils have small pores that make it harder for water to pass through. In addition, the exchange of gases is slowed down. This results in increased aeration-related problems. Fortunately, soil compaction also improves soil strength.


If you have a damaged pipe that has become deformed, you may consider re-rounding the pipe to fix the issue. Pipe re-rounding is a cost-effective solution that will save you money and time. In many cases, it will take less than an hour to perform and be permanent. Furthermore, this process won’t disturb the surrounding property.
