Most premature lining failures don't begin with the material. They begin at a weld that wasn't tested, an anchor that wasn't set, or a detail that was rushed. So we offer to install what we supply and stand behind it as one team.

ONE ACCOUNTABLE TEAM

No split responsibility. No finger-pointing.

ECP supplies industry known concrete protection liners as well as our own Infraliner concrete protection system. Pick the product that works for your project, we’re happy to install all industry products.

01 / ASSESS

Site & substrate review

We assess the asset, environment and substrate condition, and confirm the right system and detailing for the exposure.

End to end

What a supply & install package covers

A single scope, from the substrate up. Nothing left to coordinate between trades.

02 / PREPARE

Surface preparation

Substrate prepared to the standard the system requires — the foundation every reliable install depends on.

03 / INSTALL

Liner installation

Cast-in to formwork or post-installed and encapsulated, with anchors mechanically locking the liner to the concrete.

04 / WELD & TEST

Welded, tested, documented

All seams extrusion welded into one continuous barrier, every weld tested, with QA records handed over on completion.

Our installation standard

Built to be inspected, not just installed.

We work to a defined Inspection & Test Plan so quality is verified at every stage — not assumed at the end. The result is a system that performs, and a paper trail that proves it.

✔ Specialist applicators

Trained in mechanical anchoring and extrusion welding of HDPE.

✔ Every weld tested

Each seam is checked for integrity, so the watertight, chemically resistant barrier is verified and not visual-only.

✔ Inspection & Test Plan (ITP)

Agreed hold and witness points so your team, or the engineer, can verify quality as the work progresses.

✔ Handover documentation

QA records, weld test results and as-built detail handed over on completion for your asset file.

✔ Site & safety ready

Experienced working in live infrastructure, confined spaces and active sites under Australian site requirements.

Two install methods

New build or ageing asset — we install both.

Cast-in installation

For new infrastructure. We fix the liner to formwork before the pour. During placement, thousands of integral anchors embed into the concrete, locking the protection permanently into the structure.

Protection integrated from day one
Sewer tunnels, treatment plants, pump stations
Drainage structures, marine, chemical bunds

Retrofit & rehabilitation

For existing assets. We post-install the liner onto a prepared substrate and encapsulate it with specialised grout systems — upgrading ageing infrastructure without full replacement.

Extends asset life, avoids replacement cost
Tunnel remediation, pump station upgrades
Sewer rehabilitation, chemical containment

How you can engage us

Choose how much you want us to carry.

From product only, through to the whole job. Most clients looking for an installer choose supply & install — one team, one warranty conversation.

Option 01

Supply only

We provide the mechanically anchored HDPE system and the technical support to specify it correctly. Your team handles installation.

Option 02

Supply & install

We provide and install the complete system — prepared, anchored, fully welded, tested and documented. One accountable team from substrate to handover.

Option 03

Full project delivery

Design and detailing support through to installation, testing and handover — managed end to end for complex or critical assets.

A lining system is only as good as its installation.
