Mattresses are wire mesh containers to be filled with rocks to form a solid lining system in various soil retaining projects. Gabion Mattress is jumbo size gabion form with increased panel length and width, compared with other forms like baskets, boxes, cages. It has comparatively less height to suit its mat application in large bank area. Mattress gabions are flexible bank protection system with base, sides and ends normally formed a single panel of mesh fabric. Mesh form for mattress box is woven wire hexagonal netting.
Why gabion mattresses?
Mattresses are uniformly partitioned, supplied in variable size;
Mesh mat can form flexible, permeable, monolithic structures easily;
Mattresses are relatively small in height in relation to the lateral dimension of a gabion basket;
Gabion mattresses are suitable for channel linings, revetments and weirs for earth retention.
Gabion Mattresses are usually used with geo draining fabric

For riprap linings, the ability to deliver the expected channel protection depends on the proper installation of the lining. Additional design considerations for gabion linings include consideration of the wire mesh; freeboard; proper specification of gradation and thickness; and use of a filter material under the gabions.
The design procedure for gabions riprap is as follows:
Step 1. Determine channel slope, channel shape, and design discharge.
Step 2. Select a trial mattress thickness and fill rock, based on available sizes for the project.
Step 3, Determine specific weight of proposed stone.
Step 4. Estimate the depth.
