    The trees in most people's yards rarely get any attention. These homeowners typically have insurance that will protect them in the event of a disaster, such as a tree crashing through a window.

    In spite of this, trees can cause a lot more harm than you might imagine, even when nothing is falling from them. You may not even realise all the ways in which they contribute to your home's security. Most of the time, this conversation is happening below ground, out of sight.

    In this piece, we'll look at the ways in which trees can strengthen or weaken your home's muse.

    It's not uncommon for a tree's root system to extend two or three times as far as its canopy.

    Smaller roots can easily eat away at the concrete of the foundation. If you don't maintain your home, the passage of time might weaken its structural integrity.

    However, problems like subsidence and uneven soil movement due to root development are much more common. These are major issues in their own right, but they also cause water to be absorbed more quickly than usual under and around your house. When the soil's moisture level suddenly drops or rises, the pressure might cause the foundation to crack.

    In the opinion of some residents, the issue can be solved simply by cutting down any trees in the immediate area. However, this preventative strategy frequently makes things worse. Delamination of roots can hasten the process of destabilisation and raise the probability of foundation failure.

    If you want to remove trees from your property, you should talk to a professional foundation expert first.

    After a tree is cut down, the soil in its former root zone will begin to rise. It's because the soil stores more water now than it did when tree roots were soaking it up.

    The ground literally "swells" as a result of this. Generally speaking, this is a positive development. It progressively counteracts sinking or settling, providing relief from the tree's destructive effects. It could take a few months to a few years.

    • Greater water retention by the soil will prevent or reverse foundation settlement and sinking.
    • There is a greater potential for soil flooding.
    • More likely that soil may erode.

    The risk of flooding in a yard increases if trees are cut down since there won't be anything left to absorb the rainwater. If you reside in an area that has frequent or intense rainfall, cutting down a tree may result in a flooded yard. If the tree was placed on a sloping section of the lawn, its roots would help to prevent the soil from sliding down the slope. The likelihood of slope erosion is greatly increased if a living tree is removed.

    Impact of Tree Roots on Subsoil

    Even young, little roots can do significant damage to nearby trees. Roots of trees are always spreading out, since they must reach for more water and nutrients.

    What happens as a result of these shifts is dependent on the soil conditions the tree was initially planted in.

    There are two main types of soil that can be significantly altered by tree development, and the impacts are distinct for each. Clay-rich soil is the first type of soil. As tree roots dig deeper into clay soils, the earth becomes more solid and difficult to penetrate.

    On the other hand, roots are able to more readily navigate soil that is composed of loose dirt and rocks because of its tendency to shift and become displaced. It's important to know what kind of soil your house is built on because that will indicate the potential for tree roots to cause damage to your property.

    The weather is another way that trees can have an impact on the ground below them. Roots can contract as clay soils dry out during droughts, yet grow as much as ten times their original size after heavy rains. Soil can lose its structural integrity due to both shrinkage and expansion.

    Cracks in the Base and Sinking Concrete

    Even while many homeowners believe that tree roots are to blame, this is not the case. However, most foundation failures may be traced back to shifts in soil quality.

    Most frequently, this shows up as a settling concrete slab. In most cases, concrete settlement just detracts from the aesthetic value of a structure, but in other cases, it can also pose a serious safety risk.

    There is a higher probability of movement and cracking in concrete once it has settled. Depending on the magnitude of the tremor, your home's framework may be compromised. In the event that root activity simply causes concrete to crack, dwellings, especially newer ones, may not be affected in any way.

    Foundations of homes can be especially vulnerable to the effects of settling concrete. Especially in older homes, the entire building could be destroyed in the worst-case scenario.

    The ceiling could become skewed, the walls could break, and the support beams could move. Even while concrete settlement isn't always dangerous, it's a common problem in older houses and can lead to serious structural issues.

    Alternate Reasons for Cracked Foundations

    When trees cause cracks in a building's foundation, it's simple to point the finger at them because they're seen as intruders by modern, urban cultures. However, there are a variety of human activities that might weaken a building's underlying structure.

    Some examples are drainage pipes, homeowner-planted gardens, and cold basements. Soil drying out and concrete shifting are both possible results of these factors.

    What to do if your roots start to cause trouble

    Numerous preventative measures exist if you're worried about the possibility of root damage to your foundation. Most problems occur after the structure has been built and trees have been planted nearby for some time.

    Creating a root barrier is one solution to the problem. Your house's foundation may need to be dug up if you want to get this far. As you dig for the barrier, you can also trim away any roots that are getting too close to your house's base.

    Although it may be an inconvenience, it's preferable to hoping that weather and tree roots won't cause any harm to your home.

    Selecting a slow-growing tree species that has less aggressive rooting tendencies is another strategy to mitigate the risk of root damage if you're set on planting a new tree in your yard. Avoid fast-growing trees like elms, willows, and silver maples because of their invasive root systems; instead, plant oaks or sugar maples, which take their time getting big.

    You can also stop tree roots from damaging your property by rethinking your tree-planting ideas. The size of your yard is one of the most important factors to think about prior to planting a tree.

    It's a popular fallacy that a tree's roots will grow to be as wide as it is tall, however this is far from the truth. The roots of a tree can grow to be twice or even three times as tall as the tree itself.

    If you lack the area to accommodate the tree's root system, you may want to reconsider planting a tree at all or choose an other type of landscaping.

    You can avoid costly repairs to your new home or business in the future by taking precautions against root intrusion. An insufficiently deep foundation is a common source of foundation damage.

    For this reason, homes with full basements are much more resilient to root damage and concrete settling than their older counterparts built on shallow foundations. Shallow foundations are much more likely to be damaged by soil drying out or shifting, whereas a full basement provides considerable structural protection.

    If you are concerned about invasive roots, you shouldn't immediately begin taking down trees. In many cases, this is unnecessary and can be prevented using a root barrier strategy.

    Your soil and foundation can be analysed to show that roots are not a serious hazard to your home. Tree removal should only be done as a last resort when other methods have failed.

    FAQs About Arborist

    In general, arborists charge around $70 per hour, but their hourly rate may not reflect the cost of the job. The cost will depend on other factors and the number of workers who need to be on the job. If other equipment is needed, such as a truck hoist to reach tree branches, it will cost extra.

    Arborists charge higher mainly because of the complexity, unpredictability, and risky nature of the tree service. Their overhead costs are also high owing to the high insurance premiums they have to pay. All these factors then trickle down onto the final value of the quotes you'll receive.

    Arborists require a more formal education, while tree surgeons gain their experience out on the field. Both jobs can overlap, depending on the company providing tree services, and both jobs require extensive knowledge and experience working with trees.

    Level 5 arborists are fully knowledgeable and highly-qualified when it comes to tree-related jobs. That means they have the license to remove and cut trees and the training to do so safely and efficiently. Level 5 Arborists are also aware of the factors that prohibit them from removing a tree.

    An AQF Level-5 arborist, for example, has perfected their craft and is highly-qualified in all things tree-related. Not only are they qualified to cut down and remove trees safely and efficiently, but they can also spot when not to do so.

    Why Roots Love Growing Around and in the Pipes

    Trees need water, minerals, nutrients and ample oxygen for their root system to develop and thrive. Tree roots can sense where the best growing conditions are and know to take advantage of those opportunities. Studies suggest that root systems can even sense where water is flowing.

    Additionally, if you live in an urban area or a highly developed neighbourhood without a lot of nature or greenery, roots might retreat deeper into the ground, where they come into contact with your pipes. If your pipes have any exterior damage — including hairline cracks and tiny holes — the roots can worsen those problems.

    Can tree roots break water pipes? Yes. Unfortunately, roots can cause a lot of problems, including:

    • Greatly reducing or blocking pipe flow
    • Creating a dam inside pipes that leads to overflow
    • Worsening pre-existing cracks or holes in the pipe

    Although each tree species is different, root growth tends to be the most active during late spring and at the beginning of autumn. Because pipes are underground, it’s often impossible to see when root systems are threatening them. Many times, you may not know anything is wrong before symptoms begin to manifest.

    What Should I Do If I Suspect My Pipes Are Leaking From Root Damage?

    The first and most important step is to consult a professional if you suspect roots are to blame for your pipe leak. A sewer and drain repair professional understands how to clear roots from drain pipes without causing further damage and can help you determine the best steps to take moving forward.

    They may recommend a few minor repairs or harsh measures to redirect the growth of the roots or restrengthen the exterior of the pipes to prevent further damage. If the pipes are too far gone to save or too outdated to offer enough protection, you might need to re-line them. Using special equipment and techniques, a technician might be able to fix your problem without damaging your yard or landscaping.

    You might be able to remove some tree roots with a chemical treatment or root cutting machine. If the problem is serious or reoccurring, a professional might recommend that you remove the problematic tree entirely to preserve your pipe system’s structural integrity.

    Video Pipe Inspections

    Video pipe inspections are one method professionals use to assess your underground pipe situation without causing extensive yard damage or disrupting your daily routine. In a video pipe inspection, a technician will feed a specialised camera through your indoor drains and move it through your underground pipe system. Using a digital monitor and built-in signal transmitters inside the camera, the technician will find the source of the problem and create a plan of action.

    Hydro Jetting and Trenchless Pipelining

    Once a technician locates the part of your pipes that need assistance, the next step is to repair or replace the damaged lines. 

    Fortunately, modern technology lets technicians quickly address your problem with very little yard disruption through trenchless pipelining. During underground trenchless pipelining, the technician can use the Cured In Place Pipe (CIPP) restoration process to repair a damaged pipe without removing the old one. This means you don’t have to worry about trenches in your yard or to replace your sidewalk.

    Hydro Jetting is an equally environmentally friendly and time-saving repair method for small-scale plumbing concerns. Instead of digging, a technician will use a hose to move pressurised water through your underground pipes and remove any blockage or build-up.

    Trees To Avoid Planting To Prevent Damaged Pipes

    Australians love the great outdoors. Every chance we get, we migrate en masse to our scenic beaches, lush national parks, and beautiful mountain ranges. When we're not heading for the hills, we use our free time to cultivate a little patch of nature in our backyards. 

    Each weekend local nurseries are flooded with the green and not so green thumbs ready to nurture small seedlings into thriving bushes. Regrettably, not all trees are suited to a home garden environment. Some beautiful little saplings can grow up to be big structure wrecking problems.

    Plant wisely

    Making smart, educated decisions about which plants to include in your garden needs to extend further than shade, drought hardiness and how many leaves they will or won't drop in the pool. Thinking about the full life of the plant before you start digging could save on potential costs from blocked drains, damaged sewer pipes, and pulling up driveways and paths in the long term.

    Tree varieties which commonly lead to damaged drains

    Some trees are on the DO NOT plant list. These include:

    • Camphor Laurel - environmental weed in SEQ
    • Fig trees - Hills weeping fig, Moreton Bay fig, Port Jackson fig
    • Rubber plants - Indian rubber tree - weed
    • Poplars
    • Willows - weed in SEQ

    Varieties are slightly less invasive but still not recommended to plant in your garden or near drainage systems. Avoid:

    • Coral trees - emerging environmental weed in SEQ
    • Large Gum trees
    • Jacaranda - invasive weed in SEQ
    • Liquidambar
    • Norfolk Island and Bunya pines
    • Illawarra Flame Trees
    • Casuarinas
    • Australian White Cedar
    • Pine trees
    • Plane trees
    • Broadleaved Pepper trees - significant environmental weed in SEQ
    • Elms - ( - significant environmental weed in SEQ )

    The following trees and plants are not ideal for planting around your home or drains.

    • Bougainvillaeas
    • Pampas Grass - environmental weed in most areas 
    • Silky Oak
    • Hollies
    • Norfolk Island Hibiscus
    • Privets - small-leaved privet and broad-leaved privet - environmental weed in SEQ
    • Magnolias
    • Oleander - weed in SEQ
    • Canary Island Date Palm
    • Bamboo - some varieties such as golden and black bamboo spread rapidly and are classed as weeds in some parts of the country.
    • Rhus tree - weed in NSW
    • Brushbox, Tristania
    • Wisteria - Pongamia - weed

    Root systems strong enough to crack drain pipes and more

    Many of these plants have very strong, extensive root systems which will hunt down any water or nutrient source they can, often quite a distance away. This includes moisture escaping from small cracks in broken pipes and drains, the damp areas under pathways or foundations, and stormwater run-off areas.

    The destructive power of root systems can destroy fences, retaining walls, patio paving, pool infrastructure, completely block drains, and even your home's foundations. Better choices for around the garden are smaller, slower-growing trees and shrubs which have shallow root systems. Ask your plant nursery specialist or landscaper for recommendations.

    Avoid planting anything within 3 metres of sewer drains and stormwater pipes to reduce the incidence of pipe movement, cracked pipes and blocked drains from tree root intrusion.

    Prevention is always better than a cure because tree roots often return to the same pipe they were cleared from. Our recommendation is to consider the types of plants growing near your pipes.

    Garden plants and grasses have fibrous root systems, which grow on the upper soil layers and are less likely to cause sewer line problems.

    Consider what size the plant will be when it’s fully grown. We recommend slow-growing trees and shrubs with non-aggressive root systems and avoid 'tap root' systems that grow vertically downward.

    Top tips to avoid pain in the drain

    • Don’t plant too close to sewer pipes – as a general rule, at least three meters from the pipe.
    • Avoid planting near freshly laid pipes as roots are attracted to softer soil.
    • If you’re not sure where your pipes are, request a drainage plan from your local council.
    • Call Dial Before you Dig (1100), so you know where sewer pipes and other utilities are located.
    • Ask your local nursery to recommend plants with non-invasive roots.
    • Install a root barrier – available from hardware stores and nurseries. Root barriers are made from heavy cloth or plastic and are placed in the ground to contain a plant’s root system.

    It's possible for seemingly harmless saplings to develop into major issues that threaten the integrity of a building or other structure. There are several tree species that should be avoided at all costs in Queensland, including coral trees, weedy rubber plants and poplars. Plants should be spaced at least three metres away from any sewage pipes. Fences, retaining walls, patio paving, drains, and even the foundations of homes can all fall victim to a tree's roots. Smaller trees and shrubs with slower growth rates and shallower root systems are better options. Plants should be planted at least three metres away from sewage pipes and stormwater pipes to reduce the risk of root damage.
