RASCOtight Hydrophilic Systems – preventive joint sealing solutions that swell upon contact with water
RASCOtight hydrophilic products work by expanding their volume upon contact with infiltrating water. The contact pressure built up against the adjoining concrete by this expansion serves to create a watertight barrier. RASCOtight hydrophilic products can be used to waterproof construction joints and penetrations. Some products are self-adhesive while others are fixed mechanically or by (RASCObond) adhesive. The products must always be installed in such a way as to create a complete and continuous system. To prevent premature swelling of the hydrophilic strip materials, these require adequate protection against rainwater and other precipitation prior to concreting. Materials that have swollen must not be cast into the concrete.

RASCOtight Hydrophilic Channel
The RASCOtight Hydrophilic Channel is a combination of hydrophilic
strip and injection channel. The hydrophilic strip constitutes the
primary seal, while the injection channel allows the straightforward
and systematic regrouting of any defects.
Use
Hydrophilic channels are suitable for waterproofing all types of permanently accessible construction joint in general building and
civil engineering works.
RASCOtight Hydrophilic Strip
RASCOtight QVE Hydrophilic Strip is a waterproofing strip, made
from vulcanized elastomers, that swells upon contact with water.
The hydrophilic strip is finished with a protective coating to delay
initial swelling during installation.
The RASCOtight Hydrophilic Strip (SK) is also available in a
self-adhesive version.
Use
The RASCOtight QVE Hydrophilic Strip is suitable for waterproofing construction joints in general building and civil engineering works, for
sealing shafts, pipe and other penetrations, and as an ancillary measure
for other waterproofing systems.
RASCOtight Hydrophilic Paste
RASCOtight Hydrophilic Paste is a one-component polyurethane-based sealant that swells upon contact with water.
Use
In addition to standard joint sealing, RASCOtight Hydrophilic Paste is particularly suitable for waterproofing penetrations with complicated
shapes, e.g. steel sections, anchor heads, cable entries etc.
RASCOtight Hydrophilic Tie Bolt Plut / Gasket
RASCOtight Hydrophilic Tie Bolt Plugs and Gaskets are made from special acrylic polymers that swell upon contact with water.
Use
RASCOtight Hydrophilic Tie Bolt Plugs and Gaskets are used to waterproof plastics or fibre-cement tie bolts.
RASCOtight QB F2.0
RASCOtight QB F2.0 is a hydrophilic waterproofing strip based on prepolymerized acrylate. Due to this chemical base, unlimited reversibility of swelling action is guaranteed under changing loads (dry/moist).
Use
RASCOtight QB F2.0 was developed for the remedial waterproofing of expansion joints subject to relatively large movement, for all types of construction.
