- Swellable waterstops that swell in the presence of water to create a pressure seal.
- PVC waterstops that have a specific shape with bulbs that make it difficult for water to move past it within the joint.
Both types of waterstop are effective.
Swellable waterstops are more easily placed than PVC waterstops but can be dislodged during the concrete pouring process.
