Smidcrete® Aluminum Rail System AR-Series/Replaceable Seal

A heavy-duty system with a replaceable seal best suited for installation on exposed top slab decks.

The Smidcrete®/SM-Series System is specifically designed for buried joint applications. The design features a preformed elastomeric membrane which is fusion-bonded to the concrete roof slab with Smidcrete® Elastomeric Concrete. The SM-Series shapes replace the antiquated reinforced "loop joints" that historically have proven ineffective as long-term sealing systems. The Smidcrete® buried joint system isolates the expansion joint, waterproofs the joint with a pre-formed seal, and creates an "End Dam" system, while flexing in response to movement in the expansion joint width, as the structure is subjected to seasonal temperature changes.
