. Gabions are wire, stone filled cages or mattresses and are normally used to retain or protect slopes for erosion e.g. along river banks. Single skin gabion walls can be further improved by reinforcing the soil behind the wall to form a combined / reinforced soil structure. The gabion cages are usually manufacture with PVC coated hot dipped galvanised wire. The gabion cages are normally assembled in modular form with the cages available in lengths up to say 6 metres by 2 metres wide by up to 1 metre deep, which are subdivided into compartments with internal walls or baffles to provide strength for the structure. The stone fill for the gabions should be placed in the compartments by hand or machinery starting at the bottom if on a slope and working up if on say a 6 metre length, filling compartment by compartment to form the gabion structure. Fill used for gabions should be hard durable stone and not less than 75mm, and not less than 150mm for gabions in rivers or for marine works. The gabions should be slightly overfilled to allow for settlement and the lid fitted securely to the gabion baskets. For non standard shapes the gabion mattresses can be cut to size   Anguila, Antigua, Argentina, Aruba, Australia, Austria, Bahamas, Bahrain Bangladesh Barbados Belgium Belize Bermuda Bolivia Bosnia Botswana Bouvet Brazil British Virgin Islands Brunei Bulgaria Cambodia Cameroon Canada Cayman Islands Chad Chile China Colombia Commoros Congo Cook Islands Costa Rica Croatia Cuba Curacao Cyprus Czech Republic Denmark Djibouti Dominica Dominican Republic Dutch Antilles East Timor Ecuador Egypt El Salvador Equatorial Guinea Eritrea Estonia Ethiopia Falkland Islands Fiji Finland France French Guyana French Polynesia Gabon Gambia Georgia Germany Ghana Gibraltar Greece Greenland Grenada Guadelupe Guam Guatemala Guyana Haiti Holland Hong Kong Hungary Iceland India Indonesia Iran Iraq Ireland Italy Jamaica Japan Jordan Kazakhstan Kenya Korea Kuwait Laos Latvia Lebanon Lesotho Liberia Libya Liechtenstein Luxembourg Macao Macedonia Madagascar Malawi Malaysia Maldives Mali Malta Marshall Islands Martinique Mauritania Mauritius Mexico Micronisia Monaco Mongolia Monserrat Morocco Mozambique Myanmar Namibia Nauru Nepal Netherlands New Caledonia South Africa South Korea Spain Sri Lanka St Lucia St Maarten St Vincent Sudan Surinam Swaziland Sweden Switzerland Syria Taiwan Tanzania Thailand Tonga Trinidad Tunisia Turkey Turks United States America USA UAE United Arab Emerates Uganda Ukraine UK United Kingdom Uruguay US Virgin Islands New Zealand Nicaragua Niger Nigeria Niue Norfolk Island North Korea North Mariana Islands NI Northern Ireland Norway Oman Pakistan Panama Papua New Guinea Paraguay Peru Philippines Poland Puerto Rico Qatar Reunion Island Romania Russia Rwanda Saba San Marino Santo Domingo Sao Tome Saudi Arabia Senegal Serbia Seychelles Sierra Leone Singapore Slovakia Slovenia Solomon Islands Somalia Uzbekistan Vanuatu Vatican City Venezuela Vietnam  British West Indies Western Samoa Yemen Zaire Zamia Zanzibar Zimbabwe books cameras dvds shoes perfumes vitamins toys bikes mobile phones
