Hydrocor expands when exposed to moisture and provides the necessary rigid, void-free backing for elastomeric sealants subject to hydrostatic pressures. Hydrocor Type 106: self-expanding joint filler and sealer. Hydrocor Type 3: self-expanding joint filler only. Technical Support Parchem offers a technical support package to specifiers and contractors as well as on-site technical advice from staff experienced in the construction industry. 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). 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. Water excluding structures Hydrocor is suitable for filling expansion joints in basements, subways and site slabs. Examples of sealed expansion joints: Waterstop Emer-Seal 200 Polyethylene bond breaker tape Hydrocor Type 3 or Type 106 Properties Technical data Hydrocor Type 106 Form: Compressible sheet, resin bonded cork Recovery after 50% compression: Greater than 90%, less than 6 mm (under test conditions) Extrusion at 50% compression: Less than 1 mm in use Load required to compress to 50%: 1 - 2 MPa Expansion in boiling water (1 hour): 40% minimum Expansion in cold water (72 hours): 24% minimum Technical data Hydrocor Type 3 Form: Compressible sheet, resin bonded cork Recovery after 50% compression: Greater than 90% Less than 6 mm (under test conditions) Extrusion at 50% compression: Less than 1 mm in use Load required to compress to 50%: 1.3 - 1.5 MPa Expansion in boiling water (1 hour): 40% minimum Page 1 June 2014 June 2014
