(1) Accelerated low water corrosion on sheet piled
quays and steel structures in coastal environments.
Concentrated corrosion rates can dramatically reduce
the design life necessitating immediate action.

Cemprotec E942 can be spray or brush applied
in tidal zones direct to steel substrates which have
been cleaned using UHP techniques. Rapidly stabilises
to exhibit good wash-out resistance, enabling it to
be immersed soon after application.
Cemprotec Clucth Filler is available for sealing
the surface gap at the interlock or clutch to provide
complete corrosion protection in these vulnerable
areas.
Water based non-hazardous products can be used in
confined areas such as limpet or coffer dams.

(2) Failure of concrete encased steel sections on
jetties. Chlorides have ingressed, resulting in corrosion
of steel members and spalling of the protective concrete
casing requiring reinstatement to provide protection.
 |
Cemprotec E942 can be spray or brush applied
in tidal zones direct to steel substrates which have
been cleaned using UHP techniques.
Monopour PG or PC6 is used to reinstate
the concrete around steel columns, where watertight
shuttering can be erected, even in tidal zones.
On cross members, Monomix can be hand applied
although additional reinforcement may be required
to provide additional mechanical bond.
