Abstract: A connection device for fastening two expanded cellular confinement structures includes: an insertion member; an integral shank extending perpendicular from the insertion member; and an integral handle member extending perpendicular from the shank at an end of the shank remote from the insertion member. One or more barbs may project from the insertion member. The device can have a washer section between the handle member and insertion member. The handle can be curved, or it can be in the shape of a polygon.

Abstract: A mat for use in a portable porous construction mat system includes tabs for providing connections to adjacent mats. A portable porous construction mat system includes a plurality of porous units connected together with fastener arrangements. A method of providing a construction mat system includes connecting together porous units with fastener arrangements. A kit includes at least first and second porous units and fastener arrangements.

Abstract: A device that includes an insertion member, a shank, and a body having a through-hole and a post. The device can be part of a cellular confinement system. A method of transferring load from an expanded cellular confinement structure to a flexible tendon includes inserting an insertion member of a device through an open slot in the structure, inserting a tendon through a through-hole in the body of the device, and wrapping the tendon around a post of the body. A kit includes a first unitary section of cells, at least one device, and at least one tendon for securing the device and the section to allow transfer of load from the web to the tendon.
