Epoxy pipe relining is an efficient and long-lasting solution to restore old, cracked pipes. The estimated lifespan of epoxy lining is 30-50+ years while costing only 50% as much as full replacement.
Epoxy resin is a blend of an epoxy base and a hardener, creating a robust material ideal for pipeline protection when mixed. These components chemically react to create a sturdy, enduring material suited for pipeline protection.
Pipe relining involves coating the interiors of damaged pipes with a layer of epoxy resin. At Moorebank Plumbing, we use high-quality epoxy resins designed specifically for restoring old pipes. As the epoxy cures and hardens, it forms a smooth, protective barrier inside the pipe.
The resin coats the pipe walls, sealing cracks and gaps.
We prefer pipe relining with epoxy over traditional pipe replacement because it is less invasive and more cost-effective than traditional methods. With proper maintenance, epoxy materials can sustain pipe systems for over 50 years, promising long-term functionality. The process restores your pipe integrity and water flow without digging trenches or cutting infrastructure.
The durability of epoxy resin is consistent across applications, ensuring lasting performance in underground water pipe linings. Properly installed epoxy lining helps ensure a safe, reliable system for years before pipe replacements become necessary.
Typically, high-quality epoxy resin used in pipe relining can last 30 to 50 years, provided it’s correctly installed and maintained.
Compared to other pipe restoration methods like patching or sliplining, epoxy resin linings tend to last significantly longer when correctly applied. Properly cured and bonded epoxy has been independently tested to withstand decades of uninterrupted liquid exposure within pipes.
Nevertheless, the actual functional lifespan of epoxy resin is influenced by various factors. These include the specific epoxy chemistry, cure method, pipe environment, flow rates and temperatures, and maintenance practises over time.
Several key factors can shorten or extend the lifespan of epoxy resin used for pipe relining:
Extreme or fluctuating temperatures can hasten the degradation of epoxy materials. Heat accelerates the curing process, whereas cold can retard it. Frequent heating and cooling cycles weaken chemical bonds over time.
To achieve effective curing, installation should occur when ambient temperatures are between 16°C and 35°C. Ongoing exposure above 50°C drastically shortens an epoxy lining’s lifespan.
Moisture infiltration, changes in soil pH levels, ground movement, and chemical contamination from industrial processes all negatively impact epoxy pipe linings over time.
For commercial clients, industrial effluents containing acids, solvents, or petroleum distillates can degrade epoxy faster than expected.
The substrate condition strongly influences epoxy bonding and durability. Corrosion damage, mineral build-up, cracks, and loose joints undermine long-term integrity. Proper surface preparation and repair enhances adhesion.
Higher flow velocities and system pressures add physical stresses on the epoxy barrier. Gradually, this mechanical force causes thinning and weak points prone to failure.
To preserve the linings, it’s critical to monitor system conditions and regulate pressure levels.
Regular testing of aged epoxy resin ascertains its continued suitability for pipe relining. As epoxy ages, the chemical components can degrade, negatively impacting curing times, bonding strength, and durability.
It’s advisable to perform tests on stored epoxy resin approximately every six to twelve months. Furthermore, evaluate the resin’s suitability when it has been stored in improperly sealed containers, subjected to temperature fluctuations, or is beyond the manufacturer’s expiration date.
Conducting a pot life test can effectively gauge the viability of epoxy resin:
If mixed resin cures significantly faster or slower than indicated, it may be unusable for quality pipe relining. Contact the manufacturer if uncertain about test outcomes.
While simple and fast, pot life evaluations provide valuable insight on epoxy suitability and prevent rework using compromised materials. Testing helps maintain safety and consistent, long-lasting repairs you can stand behind.
At Moorebank Plumbing, we use a multi-step process to reline pipes with new, high-quality epoxy resin designed for potable water systems:
Epoxy relining offers a less invasive and more cost-effective solution than full pipe replacement, with the process typically completed within 1-2 days. The seamless epoxy barrier renews old pipes for 30-50 more years of peak performance.
As Sydney’s leading plumbing provider, we follow exacting industry standards to safely deliver robust, long-term pipe repairs. Contact our team today to evaluate your piping system!
Proper maintenance is key to maximising the lifespan of epoxy-lined pipes. While durable, the resin lining still requires care and upkeep to prevent premature breakdown.
Pipes can accumulate mineral deposits, sediment, and biofilms over time. An annual flush of epoxy-lined systems curtails buildup that may cause turbulence and friction-related deterioration.
Use only mild, non-corrosive cleaners on epoxy materials, adhering to the manufacturer’s specifications. Harsh chemicals can degrade linings faster.
Every 3-5 years, apply a microcrystalline wax coating to the interior of epoxy-lined pipes. Quality waxes enhance flow while providing an extra protective barrier.
Verify that the wax used is compatible with potable water systems. Thoroughly flush pipes post-application before restoring your water supply.
Inspect epoxy lined pipes annually for potential leaks indicating faults in the lining. Early leak detection allows for spotted repairs before major failures occur.
Monitor systems for pressure drops or flow changes signalling possible breaches. Check surrounding soil for moisture accumulating from underground leaks.
Prevent pipes from freezing in cold conditions. Expanding ice puts extreme stress on epoxy linings. Insulate exposed sections prone to freezing.
Use pressure regulating valves to maintain optimal pressures below epoxy lining maximums. Excessive pressure causes fatigue over time.
High flow velocities erode epoxy prematurely. Size piping and components to limit excessive turbulence during peak demands. Overflow routing helps shunt and smooth flows.
Properly maintained epoxy pipe linings should provide 30-50 years of outstanding performance. Contact Moorebank Plumbing to inspect and service your vital piping systems.
Pipe relining repairs broken or cracked pipes from 40mm to 225mm in diameter without having to dig up and replace pipes. Much less invasive and cheaper than replacements. Contact us to see if pipe relining is suitable for your situation.
