DUROSEAL Swelling WaterstopsThe active pre-formed sealing systemDUROSEAL swelling waterstops are waterstops which can swell and areused in concrete structures for the systematic sealing of constructionjoints (fig. 1). On contact with water, the DUROSEAL swelling waterstopsswell and seal the construction joint against water penetration.DUROSEAL swelling waterstops are characterised by:1✔ reliable swelling capacity✔ reversible swelling process✔ outstanding chemical resistance✔ drinking water compatibilityMaterialThe base material of the DUROSEAL swellingwaterstops is tough and flexible acrylate polymerswhich can store water in their molecularstructure with accompanying increase in volume(fig. 2).How it worksVolume enlargement (three-dimensional) of upto about 170 % on contact with water, with noassociated change in the homogeneous structureof the polymer matrix.During the swelling processthe DUROSEAL swelling waterstops exertpressure on the surrounding surfaces and sealsthe construction joint against water penetration.Theswelling operation and the swelling pressureit produces are illustrated in fig. 3 and fig. 4.2DUROSEAL swelling waterstops show excellent resistance to many chemicals.The following table lists a selection of the test liquids to whichDUROSEAL hydrophilic gaskets are classified resistant.Resistancy list (extract)3Test liquidPetrol, unleaded, standardDieselToluolMethanol, 50 % in waterIsopropanol, 50 % in waterEthyl acetateMethylisobutylcetoneFormaldehyde, 36 % in waterReference of following mediaMotor fuelsDiesel and heavy heating oilAromatic solventsAlcoholsAliphatic esterAliphatic cetoneAldehydeAcetic acid, 10 % in water Organic acids up to 10 %Caustic soda (pH = 11 - 12)corresponding to pH value inconcrete4Common salt, 20 % in water Saline solutions up to 20 %Sulphuric acid, 20 % Mineral acids up to 20 %2

DUROSEAL Swelling WaterstopsProcessing instructions✗5678StorageSubstratepreparationApplicationConcreting✔ DUROSEAL hydrophilic gaskets should be storedaway from moisture.✔ The substrate must be free of grease, dust andloose particles (fig. 5).✔ Standing pools of water must be dried off thesurface before attaching the swelling gasket, forexample by blowing with compressed air.✔ Application should take place shortly beforeconcreting (avoid premature swelling caused byrainfall).✔ The swelling gasket should be covered with foilin horizontal joints where pools of water canstand for some time. Rainwater will flow out ofvertical joints, so there is less risk of prematureswelling.✔ DUROSEAL swelling waterstops are fully bondedto the prepared base using DUROSEAL MKassembly adhesive (fig. 6).Mechanical fastening at intervals of about 20 cm(8“) can be employed as an alternative.✔ DUROSEAL Type U expanding joint paste may beused for bonding of gaskets on very uneven orrough surfaces.✔ The entire length of the swelling gasket must bebonded flat onto the base (fig. 7) to prevent anyleakage at a later stage.✔ The concrete covering should be at least 8 cm(3’’) thick (fig. 8). The swelling gasket should beplaced at the centre of walls which are up to 30cm (1’) thick and on the water-facing side of thewall if the wall is more than 30 cm (1’) thick,taking into account the aforementioned minimumconcrete covering.✔ Joints between two DUROSEAL swelling waterstopsshould be buttjointed.✔ When concreting, take care to ensure that theswelling gasket is fully covered by the concrete.DUROSEAL MKSwelling Gasket AdhesiveDUROSEAL MK is an MS polymer-based, solvent-free, single-componentassembly adhesive used to bond swelling gaskets to normal structuralbases (fig. 9).9AdhesivecapacityUseSafety✔ Adheres to dry and moist bases such as concrete,metals and various plastics.✔ DUROSEAL MK is supplied ready for use in 310ml cartridges and can be applied using a standardcommercially available caulking gun.✔ See product data sheet3

DUROSEAL Type U Swelling PasteThe swelling gasket that comesout of a tube.Great for constructionprogress, cures in around30minutes.DUROSEAL Type U swelling paste is a two-component expanding pastebased on tough, flexible acrylate polymers, suitable all-round for thesealing of construction joints in concrete structures (fig. 10).1011121314How it worksUseAdvantagesExamples ofuseMixinginstructions✔ On contact with water, the cured swelling gasketpaste swells and seals the construction jointagainst water penetration.✔ An increase in volume of up to around 170 %produced by storage of water in paste’s molecularstructure (see swelling curve in fig. 3).✔ DUROSEAL swelling paste is supplied in 750 mlcartridges along with appropriate hardeningpowder. The paste can be applied with a suitablehand-held gun.✔ The substrate must be free of grease, dust andloose particles.✔ The swelling paste should be protected againstpremature swelling.✔ When concreting, take care to ensure that theexpanding paste is fully covered by concrete.✔ Short cure time (approx. 20 minutes at 20 °C /68°F), so subsequent work is not delayed.✔ Adapts readily to all construction work situationsand surfaces.✔ Good adhesion to dry and moist surfaces (concrete,steel and plastics).✔ Same swelling capacity and chemical resistanceas DUROSEAL swelling waterstops.✔ Construction joints of every kind (fig. 11).✔ Junctions between concrete and steel girders(fig. 12).✔ Connecting joints in sheet pilings (fig. 13) ordiaphragm walls.✔ Sealing of bell butt joints.✔ Wall penetration for metal, plastic and concretepipes (fig. 14), cable bushing.✔ Bonding of DUROSEAL swelling waterstops onvery uneven or rough surfaces.✔ Insert the cartridge into the mixing base and fixin place.✔ Fit the colloidal mixer into a drilling machine.✔ Take off the slip lid, open and pour the hardenerpowder into the cartridge.✔ Stir the contents of the cartridge with the colloidalmixer until they become uniform colour.✔ Insert the sealing cover into the open cartridge,insert the cartridge in the gun, puncture theopening and screw on the grouting nozzle. Cutnozzle accordingly to required size of paste tobe applied.✔ The expanding paste is now ready to work(workability time at 20 °C about 20 minutes)4

DUROSEAL Sealing Rings and Plugsfor sealing formwork braces in concreteconstructionsDUROSEAL sealing rings and DUROSEAL sealing plugs are sealing elementsspecially developed for the sealing of formwork braces made offibre concrete or plastic (figs. 15, 16).151617MaterialHow theyworkStorageApplicationeasy, fast andsafeConcreting✔ The base material of DUROSEAL sealing ringsand DUROSEAL sealing plugs is tough and flexibleacrylate polymers which can store waterin their molecular structure with an accompanyingincrease in volume.✔ Volume enlargement (three-dimensional) of upto about 170 % on contact with water, withoutthe associated change in the homogeneousstructure of the polymer matrix.✔ During the swelling process the DUROSEAL sealingring or sealing plug exerts pressure on thesurrounding surfaces and seals the joint againstwater penetration (fig. 17).✔ DUROSEAL sealing rings and DUROSEAL sealingplugs should be stored away from damp.✔ The DUROSEAL sealing ring is slipped onto themiddle of the formwork braces before theseare put in place.✔ The DUROSEAL sealing plug is slipped into thecentre of the formwork stay after the formworkis removed.✔ After the formwork is removed, fill both endsof the formwork stays (fig. 17) with non-shrinksealing mortar (e.g. Tricopac 52).✔ When concreting, take care to ensure that theDUROSEAL sealing ring is fully enclosed in concreteSFR crack inducers combined withDUROSEAL swelling waterstopsfor sealing cracks and dummy jointsDUROSEAL swelling gaskets can also be used in combination withSFR crack inducers (fig. 18).The crack inducer’s intentional weakening of the cross section allows acontrolled crack to be made in the dummy-joint line and prevents anuncontrolled cracking. Sealing is provided by a DUROSEAL swellingwaterstop fixed on the crack inducer.See appropriate product data sheet for detailed information on theSFR crack inducer.185
