Sandbag retaining walls adapted for plant growth

Abstract

The sandbag for use in constructing retaining walls having a vegetation-covered wall face. The sandbag contains soil mixed with seeds as a first fill material at one end of the bag, and the remainder of the bag is filled with a cheaper fill material such as sand or gravel. The sandbags are arranged in a sandbag wall such that the ends of the bags having the soil and seed mixture forms at least part of the outer face of the wall.

       5 . A sandbag according to  claim 1  wherein said first fill material comprises soil and plant seeds.  
   
   
       6 . A sandbag according to  claim 2  wherein said first fill material comprises soil and plant seeds.  
   
   
       7 . A sandbag according to  claim 3  wherein said second fill material comprises one or more of sand, gravel and dry mix concrete, or mixtures thereof.  
   
   
       8 . A sandbag according to  claim 4  wherein said second fill material comprises one or more of sand, gravel and dry mix concrete, or mixtures thereof.  
   
   
       9 . A sandbag according to  claim 5  wherein said second fill material comprises one or more of sand, gravel and dry mix concrete, or mixtures thereof.  
   
   
       10 . A sandbag according to  claim 6  wherein said second fill material comprises one or more of sand, gravel and dry mix concrete, or mixtures thereof.  
   
   
       11 . A sandbag according to  claim 1  wherein said bag comprises geotextile.  
   
   
       12 . A sandbag according to  claim 8  wherein said bag comprises geotextile.  
   
   
       13 . A sandbag wall comprising multiple courses of sandbags according to  claim 1 .  
   
   
       14 . A sandbag wall comprising multiple courses of sandbags, said sandbags comprising a bag wall, a first end and a second end, wherein said sandbags are filled with at least two types of fill material, a first type of fill material being at said first end and a second type of fill material being at said second end.  
   
   
       15 . A sandbag wall according to  claim 14  wherein said first fill material comprises soil and said second fill material comprises one or more of sand, gravel and dry mix concrete, or mixtures thereof.  
   
   
       16 . A sandbag wall according to  claim 14  wherein said bag has a length and a width, said length being greater than said width, and said first and second ends being at opposed ends of a longitudinal axis of said sandbag.  
   
   
       17 . A sandbag wall according to  claim 15  wherein said sandbags are arranged such that said first ends of said sandbags form at least part of an outer face of said wall.  
   
   
       18 . A sandbag wall comprising multiple courses of sandbags, said sandbags comprising a bag wall, a first end and a second end, said sandbags being filled with at least two types of fill material, a first type of fill material being at said first end and a second type of fill material being spaced from said first end towards said second end, said bag having a length and a width, said length being greater than said width, and said first and second ends being at opposed ends of a longitudinal axis of said sandbag, said first fill material comprising soil and said second fill material comprising one or more of sand, gravel and dry mix concrete, or mixtures thereof.
