Reasons For Sewer or Drain Pipe Collapses

There are several potential causes for a collapsed sewer pipe, but the most prevalent ones are:

  • If pipes are not laid correctly throughout installation, they may become brittle and break.
  • You must always take the weight of any object placed on the ground above the pipelines into account. That includes concrete floors, garage flooring, driveways, trucks, and cars.
  • The amount of movement on the ground is incredible. These movements have a compressive impact on your pipes over time, which you might not feel immediately.
  • Like anything else, sewers may weaken with time and collapse under their weight if the pressure gets too high.
  • Tree roots pose a more significant threat to the durability of pipelines located near trees.

These are the most common reasons for pipe failure. However, there are more. Traditional pipe repairs can be invasive, time-consuming and expensive. Depending on the level of damage to the pipes, we recommend collapsed pipe repairs using Sydney pipe relining technology.

    Our Process

    Our plumbers are experienced in fixing blocked drains 24 hours, 7 days a week and we are very responsive meaning we can be at your location within a short period of time. Is your drain blocked and your home remedies didn’t work? Don’t worry because our equipment and skilled plumbers will get them back in order in three simple steps.


    Identifying the nature of the problem and its location inside the pipe is the initial stage in fixing it. We feed our CCTV drain camera into the drain to find out what is going on within the pipe. The drain camera inspects the pipes for damage, obstructions, and problem areas that require fixing. After this is done, we will know how to prepare the pipe for relining effectively.

    If we locate any obstructions in the pipe, we will utilise our high-pressure water jet to cleanse the pipe and its surface of any debris. This ensures a strong bond between the old line and the new relining resin. Even though we occasionally have to dig a tiny hole to gain access to the inspection aperture, we keep all of our clients in the loop and return the site to its former condition.



    The next step involves using our CCTV drain camera to take another look at the pipe once we’ve cleared it out. This is done so that the relining process may begin once the pipe has been thoroughly cleaned of any obstructions. If the line is clear of debris, we then look for and record the precise position of any damage.



    The first step in our technique is to combine the resin. After that, the liner and bladder are filled with resin and inserted into the line. Next, we inflate the liner with compressed air and secure it into position, thus making a new tube within the old one.

    Once the lining has been installed inside the original pipe, we use a robotic cutter to remove the joints, creating a new pipe within the original one.

    The Differences Between Pipe Relining and Pipe Replacement

    When a drainage or pipe segment has fully collapsed and relining is not possible, replacement is the only option. An inflated bladder is inserted during relining. Relining is difficult if there isn’t enough pipe left to cover with resin. In this situation, excavation becomes the only possible solution. This might increase the overall project cost, and completion will take more time. As mentioned earlier, we use CCTV drain inspection cameras to pinpoint the site of the collapsed/significantly damaged drain, after which we excavate and replace the problematic pipe.

    However, this process requires extensive work on the site, which causes significant interruption throughout the process. Depending on the nature and depth of the problem, this may necessitate the use of an excavator or more traditional hand-digging equipment. Pipe replacement is necessary even if a pipe can be repaired due to excessive wear and tear or age-related excavation. Sometimes it takes weeks to complete and often requires the participation of many team members. After construction is over, the landscaping may need to be redone so that the landscape looks as it did before.

    Signs That You Have Collapsed Pipes

    Here are many signs of collapsed pipe, including the following:
    Blocked Drain Sydney
    Foul Odours
    Soggy or Excessively Green Lawns
    Slow-Flowing Drains
    Blocked Drain Sydney
    Mildew/Mould Growth
    Pest Infestations
    Foundation Problems

    Signs That You Have Collapsed Pipes

    Serious consequences may result from ignoring warning signs. You can avoid pests like rats and insects if you take care of blockages as soon as they appear. Mice and rats can fit through the tiniest cracks because they are so accustomed to living in sewers.

    A Sydney pipe collapse or backed-up sewage system will have far-reaching consequences that extend well beyond your house. A blockage in the sewage system prevents waste from being flushed away. The contamination of water sources is a real risk if an underground sewage line bursts due to pressure.

    A broken drainpipe may cause a lot of trouble. To understand what’s going on, you’ll also need some background knowledge. If you’ve encountered any of the above, it’s time to call us for a sewer line inspection.

    Scheduled Inspection of Old Pipes

    It is not surprising that many older drains exhibit the same wear and tear signs, given that a cast iron pipe has a finite lifespan of just around 25 to 30 years. The roots of trees can rip through PVC pipes, while older terra cotta pipes can be broken by building settlements. Digging up your whole property to fix old pipes appears to be an awful and expensive plumbing issue when considering the cost of new additions, roads, decks, landscaping, parking spaces, and pools.

    The best way to avoid dealing with such expensive, invasive and time-consuming collapsed pipe repairs in Sydney is to get pipeline inspections done at set intervals. In addition to our high-quality reliable collapsed pipe repairs, we also offer underground pipe inspections.

    As part of these services, our certified plumbers will visit your premises at pre-planned intervals to inspect all the water, drain and sewage pipes using the latest equipment and tools like CCTV drain cameras. Catching problems early is the best way to keep expensive repairs at bay, which holds for all plumbing issues.
