SSI Highway Products Division offers a broad range of products geared towards today's transportation industry. From sealing joints in pavements to repairing holes in roadways and bridges to constructing or rehabilitating expansion joints on structures. SSI offers time-proven products and the expertise to accomplish your project. SSI offers it's own brand of materials used in new and remedial construction as well as proven products by other major suppliers to the industry.

The SSI “SILSPEC®” Brand of products dates back to 1992 with the introduction of SILSPEC 900PNS Elastomeric Mortar for bridge expansion joints. Since that time we have added Elastomeric Patching Products, Bridge Deck Overlays, Healer-sealers and Expansion Joint Seal Systems. All are listed below.
