Old wall material (6,3,4)

I believe the answer is:

wattle and daub

(Other definitions for wattle and daub that I've seen before include "Wattlework plastered with mud once used as building material" , "Wall construction using twigs, clay and water" , "Material once used for building walls -- adult BA wanted (anag)" , "Traditional building material" .)

I've seen this clue in The Times and The Sunday Times.
