Hydrophilic expandable rubber section for watertight ...

1 Hydrophilic expandablerubber section for watertightconstruction jointsWHERE TO USEFor creating water light construction joints in civil,industrial, and hydraulic application examples Waterproof joints between concrete beds andelevation walls. Waterproof contact joints between differentbuilding materials, steel and concrete, or stoneand concrete. Contact joints between different types of materials, PVC or steel tubing going through pouredconcrete in swimming pools, sewage-treatmenttanks, reservoirs, and hydraulic projects in general. Waterproof cooling joints (temporary shrinkagejoints) created during pouring to reduce the risk ofcracking in long or monolithic structures. Waterproof construction joints where conventionalwater-stop cannot be installed easily and securelybecause of the high density of the reinforcing.

2 Waterproof construction joints in tunnels, dams andhydraulic projects including reservoirs for CHARACTERISTICSI drostopis a pre-formed flexible strip, with an acrylicpolymer base specially designed to form watertight construction joints in construction up to a hydraulicpressure of 5 available in 3 sizes, 20x10 mm, 20x15 mm and 20x25 mm, labelled Idrostop 10,Idrostop 15 and Idrostop does not contain of its chemical composition Idrostopexpands gradually in permanent contact with water,creating an active barrier against water pressure(positive and negative).Unlike other materials that tend to lose efficiencyfollowing repeated cycles of expansion andcontraction, Idrostopmaintains its propertiesunchanged even in the presence of aggressive watersuch as salt water (sea water), and water in sewagetreatment plants and stable at temperatures between 30 Cand +50 Idrostopcannot be installed if the structure isimmersed in water at the time of any free water from the surface and waitseveral hours before installing the strip.

3 Idrostopcannot be used if the surface of theinstallation is heavily contaminated with acids orsolvents. Clean the surface thoroughly and consultthe MAPEI Technical [sche3] 411_idrostop_gb ( - 3 Bozza/Ciano/PDF)IdrostopIdrostopAPPLICAT ION PROCEDURES ubstrate preparationThe surface of the concrete must be cleanand solid when Idrostopis any cement laitance with a brushand sweep away any deposits that mayhave been left during pouring. Idrostopcan even be applied on slightly can be applied on concrete,metal, PVC, and natural stone withIdrostop Mastic, a ready-to-use, solvent-free single component adhesivebased on MS Masticis available in 310 extrusion the mastic becomes athixotropic paste easily applied verticallyand horizontally.

4 It reticulates with moistureto form a flexible product at temperaturesfrom +10 C to +40 a hole in the cartridge above thethreads and screw in the nozzle, cutting anopening with a diameter of 5 mm at a 45 angle. Insert the cartridge into a normalgun and extrude the adhesive onto thesurface of an Idrostopsection that hasbeen cut to size beforehand, or directlyonto the press the Idrostoponto thesubstrate, moving it slowly in all directionsto make it adhere thoroughly at all pointswithout exerting corners or seams does not requireany special procedure. Simply align thepieces of Idrostoptogether and theirsubsequent expansion will ensure a perfectseal against water facilitate application on verticalsurfaces, it is recommended that Idrostopbe cut into pieces 1 m precaution makes installation fast andsecure because it eliminates any potentialsliding caused by the weight of the pieces can however be installed bymechanically attaching the top end of theIdrostopwith screws or nails, extruding aline of adhesive directly onto the then be pressed onto thefresh adhesive to make it also be solely attachedmechanically with screws or nails placed ina row along the strip, spaced not morethan 25 cm apart.

7 IfIdrostophas been attached with IdrostopMastic, wait 24 hours before pouring waiting time can be shortened, ifnecessary, but a minimum of 4 hours mustpass after installing the Idrostop this case it is recommended that nails orscrews be placed every 1 meter to preventthe Idrostopfrom moving during the thickness of the protection pour ofIdrostopshould not be less than 8 Idrostop Masticcan be removed fromtools with common solvents (ethyl acetate,benzene, toluene). Once reticulation iscomplete, tools can only be available in 3 sizes in cartons: Idrostop 10(20x10 mm): six 10 m rolls. Idrostop 15(20x15 mm): six 7 m rolls. Idrostop 25(20x25 mm): six 5 m be stored for 12 months in adry place at temperatures between +10 Cand +40 PROFESSIONAL the technical details andrecommendations contained in this datasheet report correspond to the best of ourknowledge and experience, all the aboveinformation must, in every case, be takenas merely indicative and subject toconfirmation after long-term practicalapplications: for this reason, anyone whointends to use the product must ensurebeforehand that it is suitable for theenvisaged application: in every case, theuser alone is fully responsible for anyconsequences deriving from the use of the product.
