We install geomembrane and geosynthetic containment systems, and we document the work so the performance of the system can be verified, not assumed.
Containment performance is designed on paper and proven in the way it is built.
A lining system is only as good as the subgrade it sits on, the seams that join it, the details around every penetration and tie-in, and the tests that confirm all of it. These are execution decisions made on site, in sequence, under weather and program pressure.
The lining package is usually a modest part of the capital cost of a cell, dam or lagoon, and it carries a disproportionate share of the environmental and remediation consequence if it underperforms. Rectification after cover placement is slow, expensive and disruptive to operations.
Our answer is not a claim about outcomes. It is a method: qualified welders, an inspection and test plan agreed before deployment, hold points released only on evidence, and a documentation set that lets a third party retrace what was installed.
On landfill work, containment integrity meets or exceeds the BPEM standard and is signed off by an independent auditor, a higher bar than installer certification alone.
Deployment, welding and testing of HDPE and LLDPE geomembrane to cells, dams, ponds and capping systems, including batter work and anchor trenches.
GCL, protection and separation geotextiles, drainage geocomposites, geogrids and cushion layers, installed in the sequence the design requires.
Pipe penetrations, sumps, concrete interfaces, structural tie-ins and connections to existing lined areas, detailed and tested individually.
Non-destructive and destructive seam testing, defect repair, non-conformance close-out and the handover documentation set.
Our quality system is built around an inspection and test plan agreed with the client and, where appointed, the independent CQA consultant. Hold points are nominated before deployment and released on evidence.
Our inspection and test plans are built to meet or exceed construction quality assurance specifications approved by the EPA and following Victoria's BPEM landfill guidelines, and our landfill containment work is independently verified by the appointed environmental auditor.
Survey, surface finish and moisture verified and signed off before any material is deployed.
Hold pointDelivery inspection against roll numbers, conformance certificates and specification.
WitnessEach welder, each machine, each shift, with peel and shear results recorded before production welding.
Hold pointPanel layout recorded as installed; seams logged against welder, machine and time.
SurveillanceAir pressure, vacuum box and spark testing at the specified frequency, with repairs re-tested.
Hold pointLiner surface inspected and released to the earthworks contractor in writing.
Hold pointCertification marks are not shown on this site until current certificates and permitted wording are verified. Prequalification and certification evidence is issued on request.
Environmental protection is the outcome across all three, not a separate market.
Cell base and batter lining, capping, leachate and stormwater ponds. Composite liner systems built and documented to EPA Victoria's BPEM standard, with CQA independently verified and a full QA record at handover.
TSF and mine water storages, process ponds and heap pads, with interface and QA demands set by the tailings governance regime.
Treatment lagoons, balance and evaporation ponds, and floating covers. Scope is confirmed project by project against the specified system.
We contract directly for the lining package, installation only or supply and install, and interface with your earthworks and civil contractors.
Alygn signs, Alygn insures, Alygn is accountable for the specialist scope.
We work under head and civil contractors, inside your programme, systems, inductions and reporting requirements.
A documented confidentiality protocol applies, including where you compete with CRE Group.
Where earthworks and lining are better sequenced under one delivery arrangement, CRE Group plant, haulage and civil capability is available.
Offered on request. It is not a condition of working with Alygn.
Alygn is a standalone business within CRE Group. We hold our own contracts and insurances, and we work for head contractors who compete with CRE under a documented confidentiality protocol. Where a project benefits from integrated earthworks and lining delivery, CRE capability is available on request.
Every entry states the contracting entity and the scope Alygn or an Alygn team member performed. Project references and CQA records are available on request.
Composite lining across two engineered landfill cells, sequenced with bulk earthworks to accelerate delivery. Installation, testing and progressive CQA release maintained quality through each stage.
Large-scale composite lining across Cells 7.1 and 7.2, sequenced with earthworks and progressively tested to maintain installation quality across approximately 278,323 m².
Project reference in preparation. Full scope and delivery detail available on request.
Composite lining to the Cell 6 Stage 1A floor and northern batters, sequenced behind CRE self-delivered bulk earthworks, drill and blast and groundwater relief works across an 18,760 m² lined footprint.
