[vc_row][vc_column][vc_column_text]Stone Strong block systems are used extensively in water applications such as pond borders, stream channels, erosion and channel structures, bridge abutments and channel and storm water outfalls. The inherent durability of concrete combined with pleasing aesthetics allow for elegant erosion and retaining solutions with cost effective pricing and rapid construction.
Marine projects are an ongoing extension to freshwater applications with substantial development work currently underway. Block product for marine applications in NZ, Australia and the Pacific can use fiberglass bar reinforcement and modified concrete mixes to provide the best practicable durability available.
Depending on specific requirements, there are inherent advantages in using precast elements within a marine environment rather than attempting cast insitu works. Specialist shear pin / dowel lock block connectors are available to assist constructability in medium energy wave environments.
River, Steam + Floodway Channels
Stone Strong has been used extensively in stream and floodway channels as well as bridge training works and erosion and scour protection around built infrastructure and new works. Due to their weight, backfilled blocks have substantial resistance to tractive forces from flowing water and can be used in high-energy environments.
Precast concrete is inherently resistant to erosion and tractive forces from flowing water and flood debris. Concrete faces can be modified to provide up to 330mm thick of solid double reinforced concrete to allow for severe direct erosion applications. Specialist designs are available to counter scour and undermining problems and the system can be combined with sheet piling to provide solutions for virtually any engineering application.
Due to their weight, backfilled blocks have substantial resistance to tractive forces from flowing water and can be used in relatively high-energy environments. Free draining backfill needs to be used to control internal pore pressures and aggregate needs to be sized to ensure no internal erosion occurs on block joins or similar.
Ponds + Borders
Stone Strong blocks have been extensively used on ponds and lake edges to provide a combination of aesthetic finishes while satisfying engineering requirements.
Marine Wharfs + Seawalls
Marine projects are a specialist niche application of the Stone Strong system with significant development work underway. Fiberglass bar reinforcement and modified concrete mixes are used to provide best practicable block durability within marine environments. Specialist shear pin/dowel lock block connectors are available to assist constructability in medium energy wave environments.
Concrete block infill is generally standard for marine applications; we can offer a range of steel and polypropylene fibre reinforcement alternatives to rebar cages for infill applications or alternatively fiberglass-reinforcing bars can be used.
MSE walls can also be constructed within a marine/ tidal environment utilizing smaller sized free draining rock fill and combinations of Paragrid, Paraweb and Paraloop reinforcement. These options are potentially very cost effective where the costs of establishing larger piling plant for conventional sheet pile or bored pile construction options are prohibitive.
Water Inlets + Flow Structures
Stone Strong blocks can be used for permanent water inlets, culvert outlets or flow structures. Stone Strong blocks can be used in conjunction with or as alternatives to gabion baskets or similar for specialist applications. Designs are available for block to gabion basket connections.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=”1/1″][vc_empty_space height=”32px”][/vc_column][/vc_row]
