How To Clear Roots From Blocked Soakwells

Blocked drains are a common headache for commercial property managers, especially after a wet winter season. 

As temperatures rise over Spring and Summer, trees and plants become increasingly aggressive in seeking out moisture from the soil, and their roots can infiltrate underground pipes, drains, and soakwells in search of it. This often results in blockages that disrupt the drainage systems, leading to more severe issues if left untreated.

We’ll explore how tree roots infiltrate drainage systems, the most effective ways for professional plumbers to clear them, and why preventative maintenance is essential for commercial properties. 

Understanding the signs and solutions can help you maintain effective water drainage on your property, prevent costly repairs, and keep your commercial building’s plumbing in optimal condition.

How do tree roots block drains and soakwells?

 Tree roots naturally seek water sources to sustain their growth, particularly in warmer weather. This is a process called ‘hydrotropism’. 

In the dry season, they tend to spread aggressively toward underground moisture pockets created by leaking or cracked pipes and water-bearing drainage systems. 

Soakwells, designed to collect and disperse stormwater, become prime targets for these roots.

When roots enter these systems, they can grow quickly, forming dense blockages. They obstruct the natural flow of water and gradually weaken the structural integrity of pipes and drains, which can lead to cracks, fractures, and, in some cases, pipe collapse which can cause widespread damage to surrounding infrastructure and potentially lead to costly repairs and water damage across the property.

If tree root invasion is left unaddressed, it could cause more widespread issues like water pooling, flooding, and erosion around the property.

What are the signs of tree root blockages in commercial properties?

Being able to detect early signs of tree root blockages can save a property manager from expensive repairs and system disruptions. Key indicators include:

• Slow-draining water: One of the earliest signs of a root blockage is water draining more slowly than usual, particularly after heavy rainfall. If noticed in multiple areas of the property, it may indicate a severe obstruction.
• Unusual gurgling noises: If drains make gurgling noises even when not in use, it’s a sign of air being trapped by root obstructions within the pipes.
• Overflowing gutters and soakwells: Overflowing soakwells can be a direct sign that tree roots are blocking the drainage outlets, limiting water dispersion.
• Foul odours: Stagnant water trapped behind a blockage can lead to foul smells emanating from drains and pipes. This is often due to debris trapped alongside the root system.

How plumbers clear roots from blocked drains and soakwells

Clearing tree roots from blocked drains and soakwells requires the expertise of a professional plumbing team, as it often involves having to go deep underground into the plumbing system and surrounding areas. 

Here’s an overview of the methods employed to effectively remove roots and restore drainage flow:

1. CCTV drain inspections

Before clearing any blockage, a CCTV drain camera inspection is a valuable tool in determining the exact location and extent of root intrusion. 

Using high-definition cameras, plumbers can accurately identify problem areas without the need for excavation. This non-invasive approach not only saves time and reduces costs but also provides a visual record of the blockage.

2. Hydro-jetting

Hydro-jetting is a highly effective method to clear blockages, particularly those caused by roots. This involves the use of high-pressure water jets to blast through obstructions and clear the pipes without damaging their structure. 

3. Mechanical root cutting

In cases where roots are too dense to be removed by hydro-jetting alone, mechanical root cutting is another option. This process utilises a rotating blade that physically cuts through thick root masses, clearing the path for water flow. 

Mechanical root cutting is often followed by hydro-jetting to ensure that any remaining root fragments or debris are flushed out of the system. 

4. Chemical root treatment

For properties with recurring root issues, chemical root treatments may be applied to deter future growth. These treatments contain root inhibitors, which kill the roots within the pipes without harming the tree itself. However, this method should only be used sparingly and by qualified professionals, as improper application can lead to environmental issues.

The importance of preventative drain and soakwell maintenance

Preventative plumbing maintenance is crucial for commercial properties with surrounding greenery or tree-lined landscapes. 

While root removal solutions can restore function, without addressing the underlying causes, root intrusion may quickly become a recurrent problem. 

Below are a few preventative steps that can significantly reduce the risk of root blockages in your drainage system:

Routine inspections

Annual or bi-annual inspections, especially after the rainy season, can help identify early signs of root intrusion. By catching these issues early, professional plumbers can apply minor treatments that prevent major blockages down the line.

Pipe relining

Pipe relining is an innovative and effective way to create a seamless barrier within damaged pipes, blocking root intrusion points. This method involves inserting a liner coated with resin into the pipe. 

The resin hardens, forming a new pipe within the existing structure that is durable and resistant to root infiltration. Pipe relining is highly effective for commercial properties prone to recurrent root issues. It is also useful for older properties with clay pipes, as the clay is porous and can make it prone to recurring tree root issues.

Regular maintenance of soakwells

Soakwells play a critical role in managing stormwater on commercial properties. Over time, they can accumulate sediment and debris, which, combined with root intrusions, can lead to severe blockages. 

Regular cleaning and soakwell maintenance can extend the life of soakwells and keep them clear of debris that may otherwise attract root growth.

Strategic landscaping

If your commercial property has large, moisture-seeking trees near its plumbing systems, consider strategic landscaping to protect your drainage. 

Trees that are known for aggressive root growth, such as willow, fig, and eucalyptus, should ideally be kept at a safe distance from underground drainage infrastructure. 

If possible, consulting with a professional landscaper can provide insight into more suitable plant species for areas close to your pipes.

How to choose the right commercial plumbing partner 

When dealing with root intrusion in your drainage systems, the expertise of a skilled commercial plumber is essential.

While DIY solutions and short-term fixes might offer temporary relief, they are rarely effective in providing a long-lasting or thorough solution. Some DIY solutions might do damage to your pipes, leading to expensive repairs along the line. 

Professional plumbers are equipped with the advanced tools and industry knowledge needed to address and prevent root blockages effectively. 

Working with a plumbing team that specialises in commercial services, such as PBR Plumbing means you can expect a responsive, efficient service, minimising disruption to your property’s operation.

Don’t ignore the issue until it is too late

Ignoring root intrusion issues can lead to structural damage, costly repairs, and, in severe cases, significant downtime for your property. 

Additionally, blocked drains and soakwells can result in health and safety hazards, such as standing water and sewage backups, which pose compliance risks. 

By addressing root blockages and prioritising preventative maintenance, property managers can ensure the uninterrupted functionality of their drainage systems, lower repair costs, and preserve the long-term value of their assets.
