Sewers
- Water-blocking
- Non-disruptive
- Prevents rodents
Our hardfoam solutions for decommissioning redundant pipes and sewers are designed to be flexible, fast and non-intrusive.
Unlike labour intensive methods our team expertly inject the foam using a single access point, ensuring that the sewer is swiftly decommissioned with minimal impact to the surrounding environment.
Besides being easily implemented the foam is also an effective physical barrier. During the process the sewer is firmly stabilised and sealed preventing washouts, gas buildups and rodents from occurring.
Our process
-
Quote
We'll request the project specifications, such as pipe length, diameter and the location, and then you'll be sent our quote – usually on the same day!
-
Preparation
Filling and venting points need to be decided on and made. Before we start filling we'll do an 'air-check' to make sure we are using the correct access points.
-
Filling
Our technical specialist will fill the pipe with our hardfoam in the recommended density, which is often pre-determined by the commissioning party.
-
Completion
You'll receive a confirmation of completion along with any required documentation.
