Most waterproofing systems for engineering structure decks require a substantial amount of time-consuming manual application, which lengthens the process and makes it dependent on the weather. Eurovia has revolutionised waterproofing by developing a reliable and very effective waterproofing process that is fully mechanised: Etanplast®.

IS OUR TRADE
saving ACROSS
THE BOARD
Etanplast® is a multi-layer waterproofing / surface
course for concrete engineering structure decks. The
exclusive process is original in two ways: it uses very
high-performance polymer-modified bituminous
products and it can be mechanically laid using
equipment specific to the roadworks industry.
The benefits of Etanplast® are reflected in its
components, multi-layer structure and mechanised
laying process.
LASTING effectiveness
The use of modified binders for all layers ensures
durable high performance.
universally
proven EFFICiency
Since it was first used in 1987, Etanplast®
has been applied to high-profile, hightraffic structures in France and abroad,
including the Ile de Ré viaduct, the
Channel Tunnel terminal, the Normandy
bridge access viaducts, a wide range
of viaducts along the A26, A39, A51,
A71 and A75 motorways in France, the
Confederation Bridge and the Ile aux
Tourtes Bridge in Quebec and Turtle
Creek Dam in the United States.
The mechanised laying process ensures that the work
is uniform.
saving
The elimination of manual operations ensures rapid
laying (up to 5,000m2 per day, depending on the
structure to be waterproofed) and rapid
re-trafficking.
The waterproofing and surface courses are laid by a
single contractor, which saves considerable amounts
of time and substantially simplifies the organisation
of works.
These benefits, together with ongoing quality
control set out in the specific procedures applied
before and during Etanplast® application, ensure
faultless waterproofing.

4. Etanplast® is the first waterproofing
process to be laid by high-speed
equipment, the “MHC Complex” defined
in Update No. 2 of the STER 81 pilot file
published by Sétra in July 1990.
VERSATILE
AND CONSISTENTLY
EFFECTIVE
Etanplast® is a benchmark process that can be applied
to all types of reinforced, pre-stressed, girder and arch
segment engineering structures with concrete decks:
bridges, viaducts, cut and cover tunnels, car parks, etc.
Etanplast® can even be used on combined structures
– concrete decks over metal structures – provided
a membrane is first laid (at about 1.5kg/m2) over the
primed substrate to avoid the effects of any cracks in
the deck. The size of the structure to be waterproofed
must of course be compatible with the use of highspeed laying machinery.
Following mechanical and/or high-pressure water
cleaning of the deck, the various components of the
Etanplast® complex are applied mechanically:
old primer or special emulsion free of chlorine
C
ions
icroplast® fine-graded sand asphalt with
M
Polybitume® highly modified bitumen. Applied
in a nominal thickness of 25mm, it provides a
uniform deck surface and the ideal substrate for
the waterproofing layer. It is highly compact, thus
contributing to the waterproofing system. The choice
of binder ensures excellent rutting, fatigue and crack
resistance.

bitumen membrane which ensures the essential
waterproofing function of the complex.
rotective layer of 2.5 to 3kg/m2 of agglomerated

slate chips to ensure that the membrane can be
trafficked while the surface course is being laid and
to prevent the membrane binder from migrating into
the upper asphalt mix.

The Etanplast® process is patented.
A French Technical Opinion was issued for it in December 1996.
It has been approved by the French Railways for use on road
and rail bridges.
Etanplast® was also approved by the British Board of Agrément
(BBA) in 1995 and certified by the Quebec Ministry of Transport
in 2004.
Etanplast® is a registered trademark.
