Matacryl RB provides seamless waterproofing and extreme impact resistance under rail ballast. When required by specification, a proprietary ballast mat is placed in conjunction with RB Adhesive to seamlessly bond the mat and the waterproofing system.
Typical system build includes:
The Matacryl RB system has components that can be applied manually or by spray equipment. Contact email@example.com for application instructions.
The Matacryl membrane, once cured, offers full protection regardless of when ballast or ballast mat is placed. However, a Seal Coat is required for UV protection if system is left exposed for more than two weeks before ballast is placed.
Matacryl RB systems exceed requirements of Chapter 8, Part 29 Waterproofing of the American Railway Engineering and Maintenance-of-Way Association (AREMA) Manual for Railway Engineering. Matacryl RB meets AREMA Ballast Indentation test for use without any protection board.
