HydroPave's CONLOCK® I system provides an economical and high performance mattress system due to its single cable design. The individual units interlocked within the mattress give unequaled structural integrity. The Conlock I product is principally a cabled mattress system for submerged water placements and steep slope applications. However, several Conlock I projects have been hand placed and then "post cabled" to minimize piecework & grouting of non-interlocked seams associated with cabled systems. The Conlock cabled mattress system is a single cabled system that doesn't rely on cables to interlock. Conlock I blocks physically interlock in two horizontal directions. The Conlock I cabled system is the most cost effective and proven ACB mattress product in the marketplace.
