ACL Project List

Since its excavation and stabilization, Far View House has required significant annual maintenance and intermittent large scale remedial stabilization (1934, 1983 and 2005).  In response to past damage and collapse, a new method of capping was explored to preserve wall integrity and reduce the high maintenance cycles associated with cracked wall tops.  Soft “vegetative” capping, utilizing soil, plants, and geosynthetics was installed on a selected test wall and evaluated for its performance by monitoring moisture content, temperature and lateral movement over a period of one year.  The new intervention method was developed as a way to capture and eliminate water before it enters the exposed sandstone and earthen mortar walls, where subsequent damage from salt crystallization and freeze-thaw has been observed over many years.
