Any homeowner who has ever experienced drainage issues could tell you what a nightmare these can be, which is why many will contact the experts as soon as they spot the warning signs that something is wrong. Drainage issues can be caused by numerous factors, but did you know that one of these includes trees? In fact, trees are actually one of the most common culprits when it comes to drain damage.
Keep reading below as we go on to tell you all you need to know about how trees can cause damage to your drains, how to spot the warning signs and what can be done to fix the damage they may cause.
How Do Trees Damage Drains?
When we say that trees can cause damage to drains, we aren’t actually talking about the beautiful, luscious parts of the trees you see above ground, rather it’s what goes on underground where the issue lies.
Trees have extensive root systems underground. These roots thrive in moist, nutrient conditions and will actively seek out the damper parts of the soil; as such, they are very much attracted to the moisture-rich soil surrounding drains and sewer pipes, meaning they will grow towards these areas. Not only that, but because the earth surrounding these pipes will have been previously disturbed, it is even easier for roots to travel along these trenches that were dug to make way for the pipes and drains to be placed in comparison to undisturbed earth.
Typically, these roots will not be able to penetrate the pipes unless they are already damaged - cracks and leaks can form in drainage systems over time as a natural part of wear and tear, or sometimes after extreme weather conditions causing them to experience excessive strain. If there are weak points along the drainage system, such as a loose joint or small crack, then it is through these faults that they are able to enter, being attracted to the moisture and oxygen flowing through the pipes.
Once you have tree roots in your drain, then they will continue to grow the longer they are left before being dealt with, which can lead to further damage in the pipes as well as cause blockages, which could result in a number of repercussions for you. This is why it is important to spot any warning signs early on and act on them sooner rather than later, since this will both minimise the damage and will be easier to resolve.
Signs You Have Tree Roots in Your Drain
Being underground, spotting whether you have tree root damage in your drains through visual signs is, of course, not exactly feasible - less you go digging up your garden every week to check, though we highly doubt that. Thankfully, there are other signs that you can look out for on the surface and within your home to determine if there is a potential problem.
Signs in the Garden
One of the first places to spot signs of tree roots damaging your drain is in your garden itself. There are a couple of indicators in particular that you could look out for.
The first is if you notice any green patches in your garden compared to the rest of the area. Perhaps you have a particularly luscious patch of lawn, greener bushes in one area or one tree has suddenly seemed to grow a lot more. This could be due to certain areas of your garden having access to more nutrients than others, which could be due to tree roots blocking your drain.
The second is if you notice wet patches or sinkholes developing in your garden. If tree roots do get into your drainage pipes, they can cause a hole to develop whereby wastewater will then leak out into your garden. When areas of your garden become saturated with this wastewater, you will get muddy soft spots that will eventually start to cave in and turn into sinkholes. These will also likely smell, which is a good indicator of a burst or ruptured drain.
Signs in the Home
There are also signs you can look out for in the house; though these are indicators of potential drain damage, this could be due to a number of reasons rather than specifically tree roots, but it is still worth checking either way.
One key indicator that there is an obstruction in your drains is if your water is draining slowly. Whether it’s your bath, sink or even toilet, if you notice that these are draining slower than usual, this suggests that there is an issue under the surface. If there are tree roots in your sewer pipes, then waste will get tangled with these, making it harder for water to pass through, hence why it could be draining slower.
Leading on from this, if your water and waste continues to fail to drain successfully, it can then lead to these becoming backed-up. Rather than draining, your wastewater will have nowhere else to go but back, so you may notice that when you drain your bath, fill your sink or flush the toilet that these all instead fill up with more water and potentially waste already sitting in your drain pipes, since there is nowhere else for it to escape.
Of course, if your wastewater is building up or simply sitting in your pipes for long periods, then it is likely that you’ll notice your plumbing starting to smell. If you do find that there is a foul drain smell filling your house, then this is a telltale sign that there is a drainage problem. Whether or not this is caused by tree roots, it still needs to be checked out.
Resolving the Issue
So, now that you know what to look out for to determine whether or not you may have tree roots obstructing your drains, what’s the solution if you do? Most importantly, you need to call the experts. Though the root damage may be superficial, it is important that repair work is carried out properly and professionally to avoid further damage in the future.
Below, we’ve listed the ways a plumber may go about clearing roots from your drain and repairing any damage.
Drain Inspection
Before carrying out any repairs, it is a good idea to have a CCTV drain survey carried out on your drains. By using a drain inspection camera, a plumber will be able to more clearly see what is causing the issue, the severity of it and precisely where it is before taking any action. This is much easier and more efficient than having to dig up more of your garden than necessary in order to identify the issue and try to tackle it blind.
This also allows them to decide what method will be best to approach the problem so as not to make it worse or take longer than necessary.
Clearing Blockages
If it is established that you have tree roots blocking your drain, then there are a number of ways this can be tackled.
In the worst case scenario whereby tree roots are completely blocking your drain and have caused it to rupture, then you may require an excavation and replacement. Thankfully, however, it is often the case that blockages can be cleared using root cutting.
Though chemicals can be used to clear roots, this isn’t best to be used with plumbing since it could pollute local waterways. By using precision cutting techniques instead, the roots can be removed from within your pipes, minimising the damage to the tree whilst targeting the specific area in your drains.
If the blockage is more extensive, then another effective and safe method is hydro cutting. Using high pressure water jets, these can flush water down drains to break through the tree roots and clear them out of the way.
Pipe Relining
Once the tree roots in your drain have been removed, then it is time for the drain repairs. The most common method for this is pipe relining.
This is a quick, effective and non-disruptive method of fixing cracks and holes in pipes, whereby a liner is filled with specialist polyester resin and inserted into the drain. Once in place, this liner is inverted using water or air pressure, securing it against the rest of the pipe and covering the crack or hole, then being left to cure so that it sets into place.
Once the lining has cured, it will act as a strong barrier that is resilient to root penetration and ground movement, reducing the risk of your tree root problems recurring.
