Fields of application

Delta MS8 can be installed economically on horizontal and vertical surfaces as 'permanent formwork' below floor slab, between a subterraneous curtain wall and the structure etc. The dimpled drainage system will drain the ground water and maintain a uniform hydrostatic load throughout the structure.
