What Does an ETA Mean? The GOAT Roofing Membrane Explained

When specifying materials for roof waterproofing, performance and reliability are critical.

One of the strongest indicators of product performance in Europe is a European Technical Assessment (ETA).

The GOAT roofing membrane by Intelligent Membranes has achieved an ETA, confirming its performance as a liquid-applied roof waterproofing system.

But what does this actually mean for architects, contractors, and specifiers?

What Is an ETA (European Technical Assessment)?

A European Technical Assessment (ETA) is an official document issued under the EU Construction Products Regulation (CPR).

It provides independent verification of a product’s performance, based on rigorous testing and assessment.

An ETA allows a product to be CE marked, giving confidence that it meets European performance standards.

In simple terms:
An ETA proves that a product has been tested, assessed, and verified for real-world construction use.

What Is The GOAT Roofing Membrane?

THE GOAT is a liquid-applied, solvent-free waterproof coating designed specifically for roof waterproofing applications.

According to its ETA, the product:

• Is a polymer-based waterproof membrane

• Can be applied by roller, brush, or spray

• Forms a flexible, seamless waterproof layer

• Adheres to a wide range of roofing substrates

It is available in two versions:

• THE GOAT (standard)

• THE GOAT TH (thickened version for detailing)

Why an ETA Matters for Roofing Specifiers?

For architects and contractors, an ETA provides:

Independent Verification

The product has been assessed by an official technical body, not just the manufacturer.

Confidence in Performance

All key characteristics, including waterproofing, durability, and fire performance, are tested and documented.

Compliance with European Standards

ETA products align with the Construction Products Regulation (CPR), supporting CE marking.

Reduced Risk on Projects

Using ETA-approved systems helps reduce uncertainty in roof design and installation.

Where THE GOAT Is Used?

The ETA confirms THE GOAT is suitable for:

• Roof waterproofing systems

It is designed for non-load-bearing roof applications, protecting structures from water ingress and weathering while improving durability.

Why Liquid-Applied Roofing Membranes Are Growing?

Liquid-applied roofing systems like THE GOAT are becoming increasingly popular because they:

• Create seamless waterproof layers

• Eliminate weak points found in sheet systems

• Adapt easily to complex roof details

• Provide strong adhesion to multiple substrates

This makes them a reliable choice for both new build and roof refurbishment projects.
