Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
140 words
A fencing system comprising post members and rails for spanning between adjacent post members in use, in which the post members comprise an enclosed hollow section, a web member transversely and longitudinally extending across said hollow section and defining an internal longitudinal first compartment in said hollow section having an opening at one end of said post member, and an internal longitudinal second compartment in said hollow section transversely separated from said first compartment by said web member, said second compartment having opposed outer walls which extend away from said web member, said second compartment outer walls having apertures formed therein of a size and configuration so as to be able to receive an end portion of the rails; and ground-engageable support elements which in use extend through said end opening into only said first compartment of said post members.
Claim 2
Dependent Claim

Claim 18
Independent Claim
254 words
The method of erecting a fencing system, the method including the steps of inserting a support element for a fencing post in the ground at a desired location for said post, so that a portion of said support element extends upwardly above ground level; providing a post member comprising an enclosed hollow section, a web member transversely and longitudinally extending across said hollow section and defining an internal longitudinal first compartment in said hollow section having an opening at one end of said post member, and an internal longitudinal second compartment in said hollow section transversely separated from said first compartment by said web member, said second compartment having opposed outer walls which extend away from said web member, said second compartment outer walls having apertures formed therein of a size and configuration so as to be able to receive an end portion of the rails; locating said one end of said first compartment over said upwardly-extending portion and if necessary laterally adjusting the position of said post member relative to said support element; introducing a settable material within said first compartment to fill at least the lower end region thereof and to surround said upwardly-extending support element portion within said first compartment; allowing said settable material to set to secure the post member to the support element; and introducing fencing rails between adjacent post members thus secured at respective locations, an end portion of said rails being received within said apertures formed in the walls of said second compartment of said post members.
