Mould and rising damp problems are something the many families have been dealing with for years in Sydney due to the fact that a lot of Sydney properties are built on a rock foundation or there has been poor storm water drainage installed originally. The water which is under the house happens either after heavy rain or from a constant flow along the rock shelf. Many families have been alerted to the health issues and dangers of mould in the house which is caused by rising damp and water lying under the house or around the foundations of the building.
