Rushing to put up a concrete floodwall at your home could be worse than letting the water in, an engineer warned yesterday.


“If the wall is 70 centimetres high or more, homeowners have to carefully consider its structure and location,” said Suppachai Sinthavorn, an engineering lecturer at Srinakharinwirot University. 
A high concrete wall situated close to the house and exposed to floodwater for weeks could threaten the structural integrity of the building. 
“Water pressure will increase on the foundation and that may be enough to crack open a hole in your floor. By then, the damage will be much more than what it would be if you let the floodwater come in without the flood barrier,” he said.
