'''Wattle and Daub''' is a simple construction method in which a fence is constructed by twining flexible sticks between (non-flexible) posts, and then covering the fence in mud. Wattle fencing is constructed in the same manner, but generally leaves off the mud. |
|||
The name 'wattle' refers the flexible wooden sticks, not to a species of [[wood]], and 'daub' to the process of patting mud on the fence. The species of acacia in [[Australia]] called wattle got their name because settlers found them most suitable for use as wattles. (cf [http://www.aussie-info.com/identity/flora/wattle.php] [http://www.worldwidewattle.com/schools/name.php]) |
|||
The use of wattle and daub extended far beyond [[medieval]] [[Europe]], for instance the pre-[[Columbus|Columbian]] cultures of the [[America]]s. |

===Posts=== |
|||
Some posts with fire hardened points, modern studies showed no anti-rotting benefit of this vertical posts- round, generally with bark still on, average spacing 15-30cm. Spacing is not bigger with bigger posts, but with a few very thin internal house walls it was smaller. Occasionally posts are paired, some could be repairs (unlikely - very awkward to insert), but many appear original, to strengthen weak points. |
|||
The ends of posts adazed to rough points |
|||
Posts extend 20-40cm below ground. But that may not be original reading (don't need to be that deep) - may have been weighted down by house roofs. They were hammered into position (not inserted in dug trenches). |
|||
===Wattles=== |
|||
The size was somewhat dependent on size of posts. |
|||
More lightweight walls - fences, walls as part of a double wall construction, used av 15-25mm diameter wattles. Heavy single house walls and other heavy uses, av 20-30mm. Thinner wattles required when posts closer together, or less gaps in weave required. |
|||
Wattles most likely derived from long term coppising, especially the thicker ones. |
|||
Woven behind every second post (i.e. in front, behind, in front, behind, etc) |
|||
In one wall lowest 3 strands (and probably top 3 on some houses) plaited together as woven to form a cornice. This known from other locations ([[16th century|16th C]] [[Flemish]], modern [[Ireland]]). The strip binds the ends together better, and was probably on a movable wall - more wear and tear. |
|||
Figure-eight shaped knots of wattle found - probably used to bind tops of more roughly made walls, joins in fences and for simple joints. (similar shown in ''Lutrell psalter fl63b'') Fibres are probably twisted as worked - prevents snapping. |
|||
In some cases Blackthorn was used as wattles in lower few rows of fences (not houses), possibly to deter vermin. [[Irish]] accounts ([[12th century|12th C]] story ''Aislnge Meic Conglinne'', [[8th century|8th C]] [[laws]]) mention crests of blackthorn on fences to deter [[animal]]s. |
