Hydrocor Type 3 / Type 106
Range of self expanding cork filler
Internal & external traffic areas
Hydrocor Type 3 and Type 106 provide the necessary
support for joint sealants subject to pedestrian or wheeled
traffic. Where traffic loads may be high it is preferable to
recess the joint sealant approximately 2 mm below the
surface to avoid direct abrasion.
Uses
Forming and filling expansion and static joints in:
„„ Water retaining structures
„„ Water excluding structures
Water excluding structures
„„ Roads, bridges and carparks
Hydrocor is suitable for filling expansion joints in basements,
subways and site slabs.
„„ Internal or external traffic areas
Examples of sealed expansion joints:
Advantages
„„ Supports sealants subject to hydrostatic pressure
Emer-Seal 200
„„ Expands to fill joint
Polyethylene
bond breaker tape
„„ Will not extrude under pressure
„„ Light weight and easy to handle
„„ Resilient and waterproof

Hydrocor comprises a range of joint fillers made from cork
granules bound together with insoluble, synthetic resin.
Hydrocor expands when exposed to moisture and provides
the necessary rigid, void-free backing for elastomeric
sealants subject to hydrostatic pressures.

Design Criteria
Water retaining structures
Hydrocor Type 3 provides rigid backing essential to joint
sealing system in dams, reservoirs, culverts, canals, sea
walls and water treatment or storage structures. Used in
conjunction with suitable joint sealer (e.g Emer-Seal 200).

Hydrocor Type 3 / Type 106
Application Instructions
Supply
Do not remove waterproof wrapping from Hydrocor until
immediately prior to fixing. Hydrocor must be fixed against
one section of concrete after shutter removal.
Hydrocor Type 3: sizes from 50 mm to 610 mm in width,
thicknesses of 10 mm - 25 mm. Standard length is 1.84 m or
930 mm.
It may be fixed in place by copper nails or by bonding to
concrete using Fosroc Construction Adhesive . The next
section of concrete is then poured in place with minimal
delays, directly against the Hydrocor. After initial cure of the
concrete, the top section of the Hydrocor is removed by
power brush, grinder or saw to form a sealing slot of the
required dimensions.
Hydrocor Type 106: sizes from 50 mm to 915 mm in width,
thicknesses of 12 mm - 25 mm. Standard length is 2.3 m.
To avoid the cutting or grinding step, Hydrocor may be
initially placed below concrete surface (at depth of required
sealing slot) then another section of Hydrocor, timber or
polystyrene foam placed above the fixed Hydrocor,
reachingto the concrete surface. This unattached top section
of filler is easily removed once concrete has cured.

SPHCSPEC
Hydrocor Type 3: 50 - 610mm
SPHCSPEC
Hydrocor Type 106: 50 - 915mm
Storage
12 months in original containers when kept in cool, dry
conditions.
Note: a bond breaker such as polyethylene tape must be
applied over the Hydrocor prior to application of the joint
sealant. See individual Technical Data Sheets for details.
Limitations
Hydrocor may cause staining of the surrounding concrete in
damp conditions, especially light coloured concrete or where
exposed aggregate finishes are produced by high pressure
hosing. Staining usually disappears after 6-8 weeks normal
weathering. Stiffjoint, a non staining polyethelene foam filler
may be more suitable in such applications.
