SDH Services now use the Bolster Systems Fire Stopping App to electronically record all aspects of Fire Stopping projects.

The Bolster App allows Operatives to record the location of each fire stopped installation, capturing information on installation size, materials used, date installed, operative details, unique referencing and allows the Operative to take both before and after pictures.

The system is designed to manage the process of documenting all fire stopped penetrations within a building.

Upon completion of each project SDH Services can provide our customers with a full electronic report including marked up drawings and photographic evidence of each fire stopped installation.

The Bolster System can also be used to carry out surveys and can provide a full schedule of all surveyed works and actions required.
