The TRA-LRM membrane combines a reinforced rubber sheet with a cold applied elastomeric waterproofing adhesive for dual protection.

TRA-LRM combines the advantages of a proprietary, tough, reinforced EPDM/SBR rubber sheet with Trem-Lar LRM, a cold-applied, bitumen modified, moisture-curing polyurethane elastomer used to adhere the seam to the TRA sheet.

TRA-LRM is designed to be used in new or replacement protected membrane applications where a cold-applied, lower-odour system is desired. 

It is ideal for use on healthcare facilities and schools; in areas that are difficult to access; and in vegetated roofing assemblies.
