Patent ID: 7506480

Claim:
A method of forming at least one expansion joint adjacent artificial ground cover, the method comprising: providing an elongated expansion joint support having at least one outer surface, an upper end portion and a lower end portion; said lower end portion being shaped to operatively engage a ground surface; providing a length of expansion joint material having an upper end portion and a lower end portion; operatively coupling said expansion joint support with said expansion joint material so that at least a portion of the upper end portion of said expansion joint material extends along but beyond the upper end portion of said expansion joint support; operatively coupling the lower end portion of said expansion joint support with the ground surface such that the expansion joint support and expansion joint material form a barrier, which extends from the ground surface to the upper end portion of said expansion joint material along the lengths of the expansion joint support and expansion joint material, that substantially prevents the passage of flowable concrete past the expansion joint support and expansion joint material; pouring flowable concrete over the ground surface, in contacting relationship with both the outer surface of said joint support and an outer surface of said expansion joint material.
