Structural Waterproofing…
Structural Waterproofing of Concrete Structures:
Water-resistant concrete structures, the so called „Waterproof Concrete Structures“
have gained increasing importance in recent years.
The weak points in these structures are the joints as well as all penetrations through
the concrete structure itself.
Specialized Engineers are therefore required to exercise particular care and observe
best practice in their detailing and sealing in order to guarantee satisfactory
waterproofing performance.
Sometimes additional waterreactive membranes such as CEMtobent and/or
SilverSeal can be additionally used in order to avoid concrete crack leakages.
We support you in all questions concerning the right and cost-effectice waterproofing
design of your structure!

DualProof
This unique system produces a durable mechanical bond, which is
created when the fleece is completely bonded to fresh concrete. In
addition, the sealant prevents any lateral water underflow and migration
between the DualProof membrane system and the structural concrete.
