Swells up to 300% by volume
POLYBIT® HYDROSEAL P is a hydrophilic rubber based on polyurethane, which is available in different sizes. HYDROSEAL P is used for sealing purposes in civil engineering, structural engineering as well as tunneling for waterpressure up to 5bar. HYDROSEAL P has a three dimensional polymer structure, which is build up from unstructured polyurethane chains (macromolecules). The elastomeric features arise due to the weak cross linkage of the polymer chains. The swelling ability happens due to hydrophilic polymer resins,which can expand in contact with water in excess of 300% by volume. HYDROSEAL P is used for sealing of construction joints, restoration of expansion joints, sealing of precast concrete segments, sealing of tubbing part in tunneling, proofing of shafts and pipe penetrations. Available Pack: 10x5m & 5m
For the successful application of Hydroseal P in construction joints, the profile has to be placed into the
center of the reinforcement or at least 10 cm away from the concrete flanks. It has to be adhered fully with Polyseal PP / Polyseal Swell / Bitubond N to the substrate. If necessary the profile can also be nailed onto the concrete. It has to be sure that the profile cannot change its position while concreting. Rough surfaces should be smoothened
before adhering the profile. This can be achieved with the application of Polycrete concrete repair products or with the sealant Polyseal Swell which develops in contact with water expansion to seal any gap or undulations between the surface and Hdyroseal P.
Joints and lap-over areas are to be fixed by means of Polyseal Swell / Polyseal PP / Bitubond N.
Hydroseal P is used for sealing of construction joints, restoration of expansion joints, sealing of precast concrete segments, sealing of tubbing part in tunneling, proofing of shafts and pipe penetrations.
Bitubond N can be used for fixing Hydroseal P
Swellability in saline water is more than 100% by volume
