Idrostop ™

Hydrophilic Expandable,

Pre-Formed, Flexible Rubber Strip for Watertight Construction

DESCRIPTIONIdrostop is is used to produce watertight construction joints in civil, industrial and hydraulic construction. Construction joints created with Idrostop are watertight up to 5 atm of pressure. Unlike materials made of alternate composition that lose efficiency in repeated wet/dry cycling, Idrostop’s unique composition allows it to maintain performance even in aggressive environments.

FEATURES AND BENEFITS• Idrostop’s pre-formed flexible strip features an acrylic polymer base

specially designed to form watertight construction joints up to a hydraulic pressure of 5 atm

• Bentonite-free

• Expandsgraduallyinpermanentcontactwithwater,creatinganactivebarrier against positive and negative water pressure

• Maintainsitspropertieseveninthepresenceofaggressivewatersuchassaltwater (seawater), and water in sewage treatment plants and sewers

• Stableattemperaturesbetween-22°Fand122°F(-30°Cand50°C)

WHERE TO USE • Forwaterproofingjointsbetweenconcretefoundationsandwalls

• Forwaterproofingcontactjointsbetweendifferentbuildingmaterials,suchas steel and concrete, or stone and concrete

• Forwaterproofingcontactjointsbetweendifferenttypesofmaterials,suchas PVC or steel tubing penetrations in concrete swimming pools, sewage-treatment tanks, reservoirs, and hydraulic projects in general

• Forwaterproofingcoldjoints(temporaryshrinkagejoints)createdduringpouring to reduce the risk of cracking in long or monolithic structures

• Forwaterproofingconstructionjointswhereconventionalwater-stopscannot be installed easily and securely because of highly congested reinforcing bar

• Forwaterproofingconstructionjointsintunnels,damsandhydraulicprojects including potable water reservoirs

LIMITATIONS• Donotinstallifthestructureisimmersedinwateratthetimeofapplication.

Remove any free water from the surface and wait several hours to ensure there is no ponding of water on the surface before installing the strip.

SURFACE PREPARATION • EnsurethatthesurfaceoftheconcreteiscleanandsolidwhenIdrostop is

installed.

• Mechanicallyremoveanycementlaitanceand drops of mortar left on the surface from concrete pouring. Vacuum concrete using a brush attachment to eliminate debris and dust to provide a clean, dust-free surface.

• Idrostop can even be applied on slightly damp surfaces, when affixed mechanically orwithanMS-polymer-basedadhesive.

Note: Choose all appropriate safety equipment beforeuse.RefertoMSDSformoreinformation.

PRODUCT APPLICATIONInstallationwithAdhesive

1. Readallinstallationinstructionsthoroughlybefore installation.

2. ApplyIdrostop on concrete, metal, PVC and naturalstonewithanMS-polymer-basedcartridge adhesive.

3. Cutcartridgenozzleona45°angleandwitha3/16"(5mm)openingsize.Insertthecartridge into a standard caulking gun and extrude the adhesive evenly onto the surface of a section of Idrostop that has been pre-cut to the appropriate length, or apply adhesive directly onto the concrete.

4. PresstheIdrostop strip onto the substrate, moving it slowly in all directions to ensure full contact and thorough adhesion.

5. Formingcornersorseamsdoesnotrequireanyspecialprocedure.Simplyalignthepieces of Idrostop so that they are in complete contact with each other. Their subsequent expansion will ensure a perfect seal against water pressure.

6. Tofacilitateapplicationonverticalsurfaces,cut Idrostopintostripsmeasuring3.3feet(1m)long.Thisprecautionmakesinstallation fast and secure, eliminating any potential sliding caused by the weight of longer strips. Longer strips can be installed by mechanically attaching the top end of the Idrostop with screws or nails, and extruding a line of adhesive directly onto the substrate.

7. Press Idrostop strip onto the fresh adhesive to achieve proper adhesion.

InstallationwithScrews/Nails

1. Readallinstallationinstructionsthoroughlybefore installation.

2. Alternatively,solelyattachIdrostop mechanically with screws or nails placed in a row along the strip, spaced not more than10"(25cm)apart,toensurethoroughcontact with the substrate.

Cut the Idrostop strip to the desired length. Idrostop can be placed also with screws or nails. Place nails every 10" (25 cm).

Apply the MS-polymer-based adhesive evenly on the Idrostop or directly to the substrate.

In-line joint: Butt jointing of two pieces of Idrostop

Firmly press Idrostop, moving it in all directions to make it adhere well.

In-line joint: The two ends are staggered with an overlap of 0.8" to 1.2" (2 to 3 cm)

for a better seal.

4. EnsurethatIdrostop is positioned so that the concrete coverisatleast3"(7,5cm)wide.

STATEMENT OF RESPONSIBILITyBefore using, user shall determine the suitability of the product for its intended use and user alone assumes all risks and liability whatsoever in connection therewith. Any clAim shAll be deemed wAived unless mAde in writing to us within fifteen (15) dAys from dAte it wAs, or reAsonAbly should hAve been, discovered.

Pieces longer than 3.3 feet (1 m) can be installed on vertical surfaces by fixing the

top of the pieces with a nail or pin and then extruding the MS-polymer-based adhesive

directly onto the underlying substrate.

Where two strips of Idrostop are used side by side, 2.4" (6 cm) of concrete

is sufficient to protect the gasket.
