How can tree roots destroy pipes?

Tree root cells, which can be microscopic in their first stages of development, look for warmth and humidity so that they can mature. In their search, they are attracted to and discover drain lines, which they can penetrate through extremely small openings in the pipe joints and gradually grow inside them.

As the tree roots mature inside the pipes, they create blockages when waste water is flushed through them.

Now, one of the least efficient methods of unblocking the pipes is cutting the roots, this “pruning” action actually leads to a more vigorous tree root regrowth.

How Blocked Drains Happen

Sewer and drain pipes may not be very attractive to you, but tree roots love them.
Tree roots are lured towards your pipe because of condensation. Moisture builds up around the pipes, more so in summer because the water in the pipes is much cooler than the surrounding environment . Thirsty tree roots lock on to the trail of dampness and creep toward your pipes.

The roots will grow along the pipes until they reach a crack, they may even pry open a loose joint. Once the pipe is breached, the root will grow into it to take advantage of the nutrient-rich material inside.

As the root continues to infiltrate the pipe it grows a bundle of thin root-masses. These masses make the blockage worse by trapping kitchen grease, food oil, and large pieces of drain debris such as toilet paper.

The tree roots will eventually exert so much pressure on the pipe that they will simply destroy the section that they have grown into. The pipe may crack or burst from the outside, or it the pressure of the roots on the outside could cause the pipe to collapse in on itself.

Tree roots are not your everyday drain blockage. Most blockages can be quickly cleaned out by your local plumber. The blockages caused by roots that grow into pipes are much more complicated. Even if a plumber is able to eel out the blockage, there will still be damage to the line.

5 Ways to Prevent Blocked Drains

These simple measures will go a long way to prevent roots from infiltrating and destroying your sewer pipes

    1. Use pipes made of Polyvinyl chloride (PVC) for new and replacement drains. PVC pipes are strong enough to repel the tree roots. Experts agree that PVC is the best material for reducing the risk of tree root blockages.
    2. Don’t plant trees near pipes. This seems simple enough, but many home and business owners don’t realize what constitutes as ‘near’ when we’re talking tree roots.   Many Australian tree roots have an incredibly wide spread.
    3. Pick proper foliage. Eucalyptus, for example, can have roots systems that spread out as little as 6 metres. Hills Weeping Fig, on the other hand, can have a root spread upto 60 metres.
    4. Maintain your pipes. Wear and tear, cracks, and leaks can cause nutrient-rich water to seep into the soil around your pipes. This attracts tree roots straight to your pipes.
    5. Routinely check and clear your sewer drain. Though roots can be attracted to any type of water-bearing line, they are most often lured towards sewer drains. An expert plumber and drain cleaner can come by and clear roots out of your pipes before they become a big problem.
