Is your backyard turning into a swamp every time it rains?

At Liquid Force Plumbing, we specialise in backyard drainage repairs across Perth, helping you protect your property and enjoy your outdoor space all year round.
Why Backyard Drainage Matters
Water pooling in your backyard isn’t just an eyesore—it’s a sign of a bigger problem. Whether it’s improper grading, blocked stormwater drains, or outdated drainage systems, our licensed plumbers are trained to identify the root cause and provide lasting, practical solutions.

Common Signs You Need a Drainage Backyard Fix
Pooling Water or Puddles in Low Spots
Excess water that doesn’t drain away can cause damage to plants, grass, and structures.
Soil Erosion and Muddy Patches
If your yard is washing away or has bare patches, it’s likely from poor drainage.
Foundation or Retaining Wall Cracks
Excessive moisture can weaken the foundation, leading to costly repairs.
Dying Plants or Yellowing Grass
Waterlogged soil and poor drainage can suffocate plant roots, preventing healthy growth.
Overflowing Gutters
Clogged or improperly positioned gutters can direct water towards your yard, causing pooling and water damage.
What Causes Backyard Drainage Issues
Backyard drainage problems can stem from several underlying issues. Here’s a breakdown of the most common causes:
Poor Yard Slope & Grading
Improper yard grading prevents water from flowing away from your home, causing it to pool in low-lying areas. This can lead to water damage in your yard and foundation if left unchecked.
Blocked or Inadequate Drains
Drains clogged with debris or undersized pipes fail to handle the water flow, causing water to back up and flood your yard. Regular maintenance is key to preventing blockages.
Aging or Faulty Infrastructure
Old or corroded drainage systems often become ineffective, leading to leaks and pooling. If your system hasn’t been updated in years, it may be time for an overhaul.
Improper Soil Compaction
Compacted soil prevents water absorption, causing pooling. High-traffic areas like lawns and pathways worsen flooding. Aerating soil improves water flow and plant health.
Tree Root Intrusion
Tree roots invade pipes, causing blockages, leaks, and damage. Untreated root intrusion leads to pipe collapse. Regular checks can prevent costly drainage system repairs.
Our Complete Drainage Solutions
At Liquid Force Plumbing, we offer a range of tailored drainage solutions to suit any yard layout. Whether you need to address surface water pooling or prevent long-term damage with sub-surface systems, our expert team has you covered.
French Drains
Perfect for areas prone to flooding, French drains direct excess water away from your yard using a perforated pipe buried in a trench of gravel. This solution is especially effective in areas with high water tables and flood risks.
Trench & Channel Drains
These surface-level drains capture water from patios, driveways, and hardscapes, directing it away from vulnerable spots in your yard. Trench and channel drains are ideal for high-traffic areas where water tends to accumulate.
Swale & Spoon Drains
Shallow, vegetated channels like swales help manage stormwater runoff and prevent erosion by allowing water to infiltrate the soil. Spoon drains are particularly effective in gently sloping areas where water needs to be redirected.
Soak Wells & Sub-Surface Systems
For yards with limited space or landscaping concerns, soak wells provide a discreet way to capture and disperse stormwater underground. These systems prevent flooding by directing water deep into the ground, allowing it to be absorbed safely.
Agricultural & Specialty Drains
For larger properties or those with unique drainage challenges, agricultural drains provide a solution to manage excess water. These systems are perfect for gardens, larger backyards, or even rural properties needing additional drainage support.
How to Maintain a Healthy Backyard Drainage System
A well-installed drainage system can last for years—but like anything, it benefits from a bit of upkeep. Here are some simple ways to keep your backyard drainage working efficiently:
- Keep grates and drains clear of leaves, mulch, and debris: Blocked grates are a major cause of backyard flooding, especially in autumn or after storms.
- Inspect your downpipes and gutters regularly: Overflow from blocked gutters often leads to pooling water around your home’s foundation.
- Avoid planting large trees near pipes or soakwells: Tree roots can crack or block underground drainage over time.
- Direct garden beds and landscaping away from structures: Ensure water runs off properly and doesn’t sit around retaining walls or patios.
- Watch for early warning signs: Soft ground, strange smells, or slow-draining areas are all indicators that something isn’t quite right.
With a little proactive care, you can prevent major issues and extend the life of your drainage system. If you’re unsure about what to check, we’re happy to provide seasonal inspections and advice.
