Abstract
A pitch pocket for sealing a mechanical penetration of a roof includes a cementitious curb which defines a pocket having an upper edge, an inner surface and a base surface. An adhesive is applied to the base surface to secure the curb to the roof. A pourable, two-part urethane sealant is cast within the pocket to form a solid seal around the roof penetration with the curb.

- and
- a cast sealant within said pocket.
A method of waterproofing an opening in a roof formed by a penetration, comprising the steps of:
- placing at least a pair of cementitious curb elements around the penetration;
- joining the curb elements together in opposed relationship by applying an adhesive to joint surfaces of the elements;
- securing the elements to the roof by applying adhesive to an undersurface of the elements;
- mixing a two-part urethane rubber sealant;
