Features & Benefits

• Uses:
  • Waterproof joints between concrete beds and elevation walls
  • Contact joints between different types of materials, e.g. PVC or steel tubing going through poured concrete in swimming pools, sewage-treatment tanks, reservoirs, and hydraulic projects in general
  • Waterproof construction joints where conventional water-stop cannot be installed easily and securely because of the high density of the reinforcing
  • Waterproof construction joints in tunnels, dams and hydraulic projects including reservoirs for drinking water
• Pre-formed rubber profile with an acrylic polymer base specially designed to form watertight construction joints in construction up to a hydraulic pressure of 5 atm
• Available in 3 sizes, 20x10 mm, 20x15 mm and 20x25 mm, labelled Idrostop 10, Idrostop 15 and Idrostop 25
• Does not contain bentonite
• Unlike other materials that tend to lose efficiency following repeated cycles of expansion and contraction, Idrostop maintains its properties unchanged even in the presence of aggressive water such as salt water (sea water), and water in sewage treatment plants and sewers
• Stable at temperatures between –30°C and +50°C

Application

• The surface of the concrete must be clean and solid when Idrostop is installed
• Remove any cement laitance with a brush and sweep away any deposits that may have been left during pouring
• Idrostop can even be applied on slightly damp surfaces
• Idrostop can be applied on concrete, metal, PVC, with Idrostop Mastic, a ready-to-use, solvent-free single component adhesive based on MS polymers. After extrusion the mastic becomes a thixotropic paste easily applied vertically and horizontally. It reticulates with moisture to form a flexible product at temperatures from +10°C to +40°C
• Make a hole in the cartridge above the threads and screw in the nozzle, cutting an opening with a diameter of 5 mm at a 45° angle
• Insert the cartridge into a normal gun and extrude the adhesive onto the surface of an Idrostop section that has been cut to size beforehand, or directly onto the concrete
• Then press the Idrostop onto the substrate, moving it slowly in all directions to make it adhere thoroughly at all points without exerting traction
• Forming corners or seams does not require any special procedure. Simply align the pieces of Idrostop together and their subsequent expansion will ensure a perfect seal against water pressure
• Very long pieces can be installed in vertical mechanically attaching the top end of the Idrostop with screws or nails, extruding a line of adhesive directly onto the substrate
• Idrostop can also be solely attached mechanically with screws or nails placed in a row along the strip, spaced not more than 25 cm apart, to ensure thorough contact with the substrate
• Concrete can be poured immediately after the Idrostop is installed if attached mechanically with screws and nails
• If Idrostop has been attached with Idrostop Mastic, wait 24 hours before pouring the concrete
• The waiting time can be shortened, if necessary, but a minimum of 4 hours must pass after installing the Idrostop Mastic. In this case it is recommended that nails or screws be placed every 1 meter to prevent the Idrostop from moving during the pour. The thickness of the protection pour of Idrostop should not be less than 8 cm
• Wet Idrostop Mastic can be removed from tools with common solvents (ethyl acetate, benzene, toluene). Once reticulation is complete, tools can only be cleaned mechanically

Limitations

• Idrostop cannot be installed if the structure is immersed in water at the time of application
• Remove any free water from the surface and wait several hours before installing the strip
• Idrostop cannot be used if the surface of the installation is heavily contaminated with acids or solvents. Clean the surface thoroughly
