Concrete Biscuit Ring Cover Slabs

Concrete cover slabs, also known as concrete biscuit rings, reducing slabs or landing slabs, provide a platform to cap a manhole chamber and a base for any brickwork prior to finishing the chamber with a manhole cover.

JDP Technical Support can guide you on concrete ring requirements, drainage system designs or on-site take offs. Contact us for more information.
