Hi, The foundations around front of house and garage internal & external brick walls 3-400mm from ground has been deteriorating for many years & now getting worse, the house is on unlevel block so all the lower parts of wall around front of house & in garage have rising damp, after doing research, i will try DYI , but what is the SILICONE i need to inject through drilled holes & what is the procedure ?, does Bunnings sell this SILICONE ? regards Graeme
