How to Float Concrete at Waterstop Joint 1) Limit concrete placement to the elevation of the waterstop in the first pass, and 2) vibrate concrete under the waterstop. 3) Lift waterstop legs to confirm full consolidation without voids, then 4) place remaining concrete to the top of the slab.

Earth Shield Type NB190 Hydrophilic Waterstop Paste is for use in concrete cold joints, precast joints, tunnel segments, pipe penetrations, and as an optional adhesive for Type NB190 hydrophilic chloroprene rubber waterstops. The product has a 250% expansion when immersed in freshwater for 30 days.

This is why edge welded waterstop is unacceptable. The joints are so weak you can actually tear them apart! The edge welded waterstop lacks the proper tensile strength and does not maintain the parent material's bulb or rib continuity. Consequently, the waterstop often tears at the most critical junction: the change of direction. All waterstops act as a continuous, fluid-tight diaphragm with fluids (generally water) traverse. The structure that uses edge welded waterstop will... naturally leak, as fluids migrate to any tears in the weld and pass through to the other side of the joint. Structures that use Shop Made Fittings will significantly reduce these waterstop failures. The weld's tensile strength will be at least 80% of the parent material, maintaining the continuity of the bulbs and ribs across the weld. In other words, the waterstop will perform as intended and last the life of the structure.
