Modular barrier system

A modular barrier system comprising:

• a plurality of plastic wall members, each including a shell which encloses a hollow space, and each linearly aligned with its nearest neighbor, thereby forming a piecewise continuous wall enclosing an area defined by that wall;
• a plurality of elongated links, each link having two ends, each end being connected to an end of its nearest neighbor thereby forming a closed chain, the chain being disposed against an outside of said wall, the outside of the wall being a side of the wall facing away from the enclosed area;
• and
• a waterproof tarp extending over the defined area, and underneath and beyond the wall, an edge of the tarp being folded upwards along the outside of the wall and secured to the links.

A method for installing a modular barrier system comprising:

• laying a waterproof tarp on a ground surface;
• placing a plurality of wall members on the tarp at defined locations, the wall members being disposed next to one another, forming a piecewise continuous wall which encloses an area defined by that wall;
• placing a plurality of links against an outer side of the wall members, the outer side being a side facing away from the enclosed area, and connecting the plurality of links to each other to form a closed chain of links;
• and
• folding an edge portion of the tarp upwards along the outer side of the wall and securing the edge portions to the links.
