Extend the Life of Underground Infrastructure with Manhole Lining and Rehabilitation
Pipe Management Australia (PMA) delivers quality manhole lining and rehabilitation. Manholes, also known as maintenance holes, are essential access points in sewer and drainage systems, allowing for inspection, cleaning, and ventilation. Despite their importance, they are often overlooked in infrastructure maintenance plans and left vulnerable to corrosion, cracks, and groundwater infiltration. Recognising this gap, PMA has pioneered advanced manhole lining and rehabilitation solutions designed to safeguard these critical structures for decades to come.
With over 20 years of experience and a team of nearly 240 skilled specialists, PMA is a trusted utilities management provider operating along Australia’s east coast. We partner with councils, cities, and private organisations to maintain efficient stormwater and sewer networks. Backed by more than 150 years of combined leadership experience, PMA ensures communities flow freely, safely, efficiently, and sustainably. Our team has the experience to deliver a selection of relining methodologies and is supported by our other utility maintenance services including maintenance hole inspections and minor civil works. Through innovation, experience, and precision, PMA continues to redefine the standards for manhole rehabilitation.
The Next Generation of Manhole Lining Technology
In sewer environments, manholes are constantly exposed to corrosive gases such as hydrogen sulphide, which, when combined with moisture, produces sulfuric acid. This acid aggressively attacks concrete walls, leading to surface erosion, structural cracks, and infiltration. Over time, these defects allow groundwater to enter the sewer system or sewage to leak into surrounding soils. Pipe Management Australia identified the need for a robust, durable, and low-risk repair method. This led to the introduction of Panel Lok, an innovative PVC lining system initially developed for large-diameter pipes, now adapted for maintenance hole rehabilitation with exceptional success.
While Panel Lok is a proven manhole relining solution with decades of successful field implementation, when it was originally introduced it represented a significant advancement in maintenance hole rehabilitation. Unlike traditional methods applied directly on-site, Panel Lok is a factory-manufactured, precision-engineered PVC liner that is assembled on-site within the maintenance hole. Each liner consists of interlocking PVC panels fabricated in a controlled environment to exact specifications. This ensures consistent quality and eliminates the variability that often affects field-applied coatings.

Fast, Safe, and Sustainable Manhole Rehabilitation
Because Panel Lok is a structural system, it can provide independent support, meaning it can stand alone even if the original concrete or brick structure continues to deteriorate. The PVC material is highly resistant to corrosion, sewer gases, and microbiological attack, ensuring long-term protection in harsh wastewater conditions. Despite its strength, the liner is designed to minimise reduction in the asset's internal diameter, maximising flow capacity and maintaining operational efficiency.
Panel Lok liners are 100% Australian-made, ensuring consistent supply, quality assurance, and local support. The controlled manufacturing process also enables faster project mobilisation, as installers don’t face delays waiting for imported materials or site curing times. One of the standout benefits of Panel Lok is the installation speed. In most cases, a maintenance hole can be fully relined within a single work shift.
