Overview
PENEBAR™ SW-55 is a bentonite infused butyl rubber waterstop developed to stop water penetration through cast in place concrete joints by expanding in a controlled fashion when exposed to water and making a positive seal inside and against the concrete. Its superior ability to expand and seal concrete joints allows it to replace the more passive tied in PVC waterstop systems and eliminate welding irons, split forming and special shapes.
Applications
PENEBAR™ SW-55 can be applied to non moving, concrete construction joints for both horizontal and vertical applications. It can be used on new or existing concrete, irregular surfaces and through wall or slab penetrations, such as pipes, utility lines, piling and steel members.
Other typical applications that are ideal for PENEBAR™ SW-55 are: underground structures, basements, precast panels, tunnels, manholes, lift pits, retaining walls, concrete pipes and storage tanks.

Complies and meets the requirements to EU REACH Regulation (EC) No 1907/2006 Article 33(1) Obligation to provide information of safe use.
Special considerations
- Always use PENEBAR™ PRIMER to ensure tight adhesion and to aid in preventing PENEBAR™ SW-55 from moving during the concrete pour. For vertical surfaces, nails may be used to hold the product in place in conjunction with PENEBAR™ PRIMER.
- PENEBAR™ SW-55 should be used at a minimum depth of 50 mm (2 in) inside the concrete.
- When used on pipes and other structural penetrations, PENEBAR™ SW-55 should be cut to measured length and placed around the penetration with ends butted.
- In all cases, PENEBAR™ SW-55 should be in direct contact with the substrate along the entire length of the installation.
- PENEBAR™ SW-55 is not an expansion joint sealant and is only suitable for non moving concrete joints.
- PENEBAR™ SW-55 should not be installed in standing water or on frozen or icy surfaces.
