INTRODUCTION

Rockmax Adhesive 11 is a one part, ready to use contact adhesive based on polychloroprene. It can be used for installation hydrophilic rubber waterstops on dry concrete substrates.

APPLICATION AND INSTALLATION

PREPARATION

The concrete substrate must be sound, clean, dry and free from oil, mould oil, grease, dust, dirt, cement paste and loose contaminants. In case of dust and dirt we recommended clean by compressed air. Do not use water to clean.

APPLICATION

Apply Rockmax Adhesive 11 by brush on both adhere surface. All area of surface to bond must be cover with adhesive. Wait the adhesive to initial cure (or touch dry) at approximate 5-10 minutes depend on ambient temperature but no longer than 30 minutes. Press the rubber waterstop on the surface with constant pressure along the length of the joint. Use rubber hammer or steel roller for making rubber waterstop perfectly attached to the concrete surface. Allow the adhesive to cure at approximate 30 minute. Fully cure in 24 hours.

PROCEDURE COLD JOINING OF RUBBER WATERSTOP

1. Cut waterstop ends straight and true using sharp knife or saw blade.
2. Clean and roughen the ends of the waterstop using abrasive paper and or wire brush 100mm from the end. Drill the hole for insert steel bolts.
3. Clean the roughen surfaces using the clean cloth and water. Allow to dry.
4. Apply a thin coat of adhesive to all surfaces, as the adhesive becomes tacky insert the end of the waterstop into the fitting. Be sure to insert to the full depth of the fitting and hand press together.
5. Clamp all bonded areas using the steel bolts in to the holes and let set for 2 hours.
6. Do not pull the bonded area for at least 24 hours.
7. Bonds will reach maximum strength in approximately 14 days.

INTRODUCTION

Rockmax Tunnelstop is a hydrophilic rubber sealing material strip for sealing joints in precast concrete tunnel segments. It‘s designed for especially high water pressure. Rockmax Tunnelstop is formulated from high grade elastomeric material and hydrophilic resins. It will swell (more than 300%) when contact with water to perform internal pressure inside the joints against the water leaks.

AREA OF USES

Rockmax Tunnelstop designed especially for precast concrete tunnel segments with and including underground precast structures, steel and concrete joints and various civil engineering construction projects.

ADVANTAGES

High water pressure resistance.

High swelling rate (>300%).

Stability and long term services.

Durability.

Can tailor of profile and size to fit     the design segments.

Not affected by repeat wet and     dry cycles.

No problems with compression     or abrasion during installation     segments.

Easy to install.

APPLICATION AND INSTALLATION

PREPARATION

The grove joints must be clean and free from oil, grease, dust, dirt, mould oil, cement paste and other contaminants. Ensure the concrete joints is sound and dry. No crack, damage, holes on concrete surface. Repair must be made prior to install waterstop strip. The water could enter from those damaged concrete.

INSTALLATION

Apply Rockmax Tunnelstop Adhesive along the joints. Allow adhesive to curing and become tacky. Apply the Rockmax Tunnelstop strip to the substrate. Use rubber hammer to finish the strip lightly. Connection joints by butted together only. Do not overlap. Keep the installed waterstop strip in shade and do not exposed to rain water or ground water.
