1. A deck plank for use in building a deck, said deck plank having an elongated length, two opposite sides extending along said elongated length, two ends located on opposite ends of said elongated length, and a continuous cross-section along said elongated length, said deck plank comprising an insertion member extending the length of one of said two sides and forming a groove extending the length thereof, said groove comprising opposing ribs shaped to retain a sealing gasket therein, said ribs separated by a space and defining an indentation above said groove, in said insertion member for receiving a gasket compression tab; the second of said two sides includes said gasket compression tab extending the length of said second side and having a substantially flat underside and shaped and adapted to engage in an indentation of a substantially identical adjacent deck plank, wherein said substantially flat underside is adapted to rest on a sealing gasket above a groove of said adjacent deck plank when engaged, and to compress the sealing gasket in said groove of said adjacent deck plank to thereby form a water barrier between said deck plank and said adjacent deck plank; said second of said two sides further includes an end rib, a planar surface, and a fulcrum member each extending the length thereof, wherein said fulcrum member is adapted to engage a surface of said adjacent deck plank when said insertion member of said adjacent deck plank engages said gasket compression tab of said deck plank, thereby adapted to create a compressive force between said insertion member of said adjacent deck plank when engaging said gasket compression tab of said deck plank, said end rib extending from said plank with a slant for providing a contact surface with an end rib contacting part of said insertion member when said compression tab is engaged and wherein said end rib contacting part is angled to match said slant of said end rib. |
