EVO Rock Bags · Guides
Rock bag guides for engineers and contractors
How rock bags are used for erosion and scour control, how they compare with other systems, and how to size and specify them. Written by EVOSNT, the manufacturer of EVO Rock Bags.
Size and specify
Pick a bag size from the design current and drop a specification clause into your tender.
Specify
How to choose a rock bag size: 2 ton, 4 ton or 8 ton
Choose the right rock bag size from your design current velocity. Ratings for 2, 4 and 8 ton EVO Rock Bags, single and grouped, with dimensions, rock size and a quick selector.
Specify
Rock bag specification clause for tender documents
A rock bag specification clause you can copy into tender documents and adapt: materials, fill, sizes, filling, placement, inspection and submittals.
Applications
Where rock bags go, what fails without protection, and how the bags are laid out.
Application
Bridge pier and abutment scour protection with rock bags
How rock bags protect bridge piers and abutments from local scour: why scour happens, how the bags are laid around a pier, and when to choose them over loose riprap.
Application
Port, quay wall and berth scour protection with rock bags
Rock bags for ports and harbours: protecting quay walls, berths and breakwater toes from propeller wash, currents and wave action.
Application
Outfall, culvert and drainage channel protection with rock bags
Rock bags at stormwater outfalls, culvert outlets and drainage channels: stopping scour holes and undermining where concentrated flow leaves a pipe.
Application
Coastal and shoreline erosion protection with rock bags
Rock bags for coastal revetments, shorelines and intertidal zones: how they protect against waves and tidal currents, and design points for Gulf and hot-climate coasts.
Application
Riverbank erosion control and revetment with rock bags
Rock bags for riverbank revetment, bank toe protection and river bottom protection: causes of bank erosion, layouts that work, and how rock bags fit bioengineering designs.
Application
Offshore wind, subsea cable and pipeline protection with rock bags
Rock bags offshore: scour protection at wind turbine foundations, cable protection at J-tubes and crossings, and pipeline stabilization, placed from a vessel crane.
Compare
Rock bags next to riprap, gabions, concrete mattresses and sand containers, side by side.
Comparison
Rock bags vs riprap: which to use for erosion and scour
A side-by-side comparison of rock bags and loose riprap: rock size, placement, filter layers, behaviour at the edges, inspection and where each one is the better choice.
Comparison
Rock bags vs gabions: flexibility, durability and placement
Rock bags and gabions compared: wire baskets against flexible nets, filling, placement underwater, durability in salt water and where each one works best.
Comparison
Rock bags vs concrete mattresses for scour and subsea protection
Rock bags compared with articulated concrete mattresses for scour protection, pipeline and cable cover: flexibility, handling, habitat and where each one fits.
Comparison
Rock bags vs geotextile sand containers
Rock-filled net bags compared with sand-filled geotextile containers: weight, current resistance, damage from UV and debris, and when each one is the right choice.
