Tree Roots Solutions for Your Pool Area Pipes

Your pool area may look beautiful, but you could be facing persistent drain backups nearby. In the Sutherland Shire and southern Sydney, our investigations using advanced camera technology in blocked sewer or stormwater lines adjacent to pools frequently reveal invasive tree roots that have penetrated the joints of older pipe systems.

Resolving a blocked pool drain doesn’t always require lifting pavers or excavating your garden. This article explores the various causes of blockages, the techniques we employ to identify them, and how pipe relining offers an efficient solution by addressing the issue from within the pipe itself.

What Drainage Systems Lie Beneath Your Pool Area?

In many Sydney backyard pools, the surrounding areas are typically covered with materials like paving, tiles, decking, retaining walls, and garden beds. Beneath this hardscape, you will usually find several drainage lines:

• The household sewer line
• Stormwater drainage systems from the roof, paving, and pool surroundings
• The pool backwash line
• Overflow drains and subsoil drains

It is essential to recognise that the pool’s filtration pipework, which connects the pump, filter, skimmer box, and return jets, operates under pressure and is separate from the drainage systems. This discussion focuses on the drainage lines that are particularly vulnerable to tree root intrusion.

How Do Tree Roots Cause Blockages in Pool Drains?

Tree roots are naturally attracted to sources of moisture. Even a minor leak at a pipe joint can draw them in. Roots from trees several metres away can extend towards a damaged joint in older terracotta, earthenware, or PVC pipes. Once a small root gains access, it thrives in the damp environment within the pipe, trapping waste and debris, and eventually leading to a blockage.

When a drain near the pool becomes blocked, the backwash water has no outlet, potentially resulting in flooding on the pool deck. If the blockage occurs within the sewer line, it can cause showers, toilets, and floor wastes inside the house to back up.

If you are landscaping around a new pool, consider consulting our guide on suitable tree species to plant to prevent blocked drains. This guide offers recommendations on trees that are safer to position near pipework.

What Signs Indicate a Blocked Pool Drain or Stormwater Line?

Be vigilant for the following symptoms around your pool and within your home:

• Pool water drains slowly or backs up during backwashing
• The backwash line overflows
• Water bubbles up through a garden drain or grate
• A sink or shower emits gurgling sounds when the pool is backwashed
• Water collects on the pavers or lawn near the pool

Each of these signs indicates a potentially blocked or damaged pipe underground, and a camera inspection will help us accurately identify the problem.

Why Is Avoiding Excavation Around a Pool Important?

Gaining access to drainage around a pool can be challenging and often results in damage. Reaching a pipe usually requires lifting travertine or granite pavers, cutting through concrete slabs or retaining edges, or removing garden beds, turf, or decking. After repairing the pipe, reinstating the paving and landscaping can be extensive and expensive.

That’s why we prefer relining methods over excavation. In the case illustrated below, relining allowed us to navigate around steep stairs and an established garden without causing disruption.

Case Study: Successful Pipe Relining Solutions Near a Pool in Sutherland Shire

A homeowner in the Sutherland Shire contacted us about three significant issues in their backyard:

• A blocked stormwater line next to their in-ground pool
• Gurgling noises from the back garden
• Water pooling in a tiled corner

Our CCTV drain inspection revealed significant root intrusion from a nearby tree, cracks in an old earthenware line, and multiple blocked junctions located approximately 3 metres beneath the pavers.

The images provided illustrate the situation: the first depicts the blocked pipe before intervention, while the second shows the same pipe post-relining.

Instead of suggesting excavation, we followed these steps:

1. We cleared the line using high-pressure hydro jetting and root-cutting tools.
2. We installed a resin liner throughout the damaged section to seal the cracked junctions and joints.

The stormwater line was restored to its optimal flow without disturbing the pavers or garden beds. The entire process was completed in under six hours.

What Is the Process for Pipe Relining Without Excavation?

We employ a technique known as cured-in-place pipe relining. A resin-soaked liner is inserted into the damaged section of the pipe, pressed against the interior surface, and left to cure, effectively creating a new pipe within the old one. This method seals any cracks, leaking joints, and entry points exploited by tree roots. We access the pipe through an existing entry point, such as an inspection opening, ensuring that the surrounding pavers and garden remain undisturbed.

Our dedicated team manages every stage of the relining process, from the initial camera inspection to the final stages, without the use of subcontractors. For further details on the procedure, please visit our pipe relining Sydney page.

When Is Pipe Relining Not Suitable for Pool Drain Repairs?

Pipe relining is appropriate for pipes that are damaged but retain most of their shape. If a section has collapsed to such an extent that a liner cannot be inserted, that segment will require excavation and replacement. Likewise, if a section has sunk and lost its gradient, the liner will follow the dip, resulting in stagnant water, which necessitates the reinstallation of the pipe at the correct slope.

Occasionally, our camera inspections reveal that roots have penetrated the Sydney Water main rather than your private pipes. In these cases, the responsibility for repairs rests with Sydney Water, and we provide the footage necessary to facilitate the reporting process.

Frequently Asked Questions About Blocked Pool Drains

Can the Drain Pipes Surrounding a Pool Be Relined?

Absolutely. We can reline the sewer and stormwater pipes located beneath pool surrounds, provided the pipe retains its shape. A camera inspection is performed first to assess the damage and ensure that a liner can be installed. If any sections have collapsed or sunk, those areas will need to be excavated and replaced.

What Techniques Are Used to Resolve a Blocked Pool Drain Without Excavation?

We clear the blockage using high-pressure hydro jetting and root-cutting tools. Following this, we inspect the pipe with a CCTV camera. If the camera identifies cracked joints or root entry points, we can install a resin liner from within the pipe through an existing access point. This repair effectively seals the damage without the need to lift pavers, cut slabs, or disturb the garden.

What Common Causes Contribute to Blocked Drains Around Pools in Sydney?

Tree roots are a primary cause we encounter around pools, especially in older terracotta and earthenware pipes. Roots penetrate joints that leak water and continue to grow until they trap debris. A camera inspection will help identify the specific cause of the blockage in your drain.

Who Is Responsible for Removing Tree Roots from a Sewer Pipe in Sydney?

The property owner is responsible for their own pipes. According to Sydney Water’s guidelines regarding repair responsibilities, the owner must also clear tree roots that invade the junction at the connection point. If our camera footage shows that the roots are within the Sydney Water main, the responsibility for repairs lies with Sydney Water, and we will provide the necessary footage to report it.

How Long Does Pipe Relining Take Near a Pool?

The relining project in Sutherland Shire, mentioned in this article, was completed in under six hours, including root clearing and lining of the damaged section. The duration for your drain will depend on the length of the damaged area, the number of joints needing sealing, and the accessibility of the entry point. We will provide you with a timeline following the camera inspection.

Schedule a CCTV Inspection for Your Blocked Drain Near the Pool

We aim to identify a method for repairing the drain from within the pipe before considering excavation, and we will share the camera footage with you before commencing any work.

If you notice signs of a blocked drain near your pool, schedule a CCTV inspection or contact The Blocked Drain Guys at 0418 408 333. Craig or one of our team members will explain the inspection process and what we will be looking for.
