Raft foundations for low-rise buildings
In October last year, Mr J. O’Rourke described some methods adopted in the Wrekin District for the construction of raft foundations to counter the effects of mining subsidence. Some amendments to these were suggested by Mr T. Holden Brown in February, but Mr D. R. Robinson, who is with the Poole Borough Council, has now written to express his disagreement with these suggested amendments. He continues: If the cavity is closed by the additional 150mm-thick mass concrete, water running down the cavity will build up on the mass concrete and cause dampness on the inner blockwork and the screed.
