What are you here for? Concre t ing around a house to direct water away is standard practice. Forget about the mould. Any signs of house movement? Cracks, sticky doors/windows? Patched mortar, plaster etc? What's the location of the home and do you onow the soil type? Thanks for replying. The professionals advised me that if I want to get the water away from the house I should concrete. My question is more about the potential issues it can cause to the house structure if I do nothing. And whether this can damage the structure. The house is located in Golden Beach in QLD. There are no signs of house movement or cracks or stick doors/windows. And no visible patched motard. I'm not familiar with the location's soil profile though you should try to work that one out. uneven moisture levels around your foundation can be devastating to the home depending on the soil type. If you are on a reactive clay, the scenario you describe could leard to slab heave (look this up) which can cause damage to the structure and its foundations. That is the purpose of the concrete; to direct the water away and, in theory, keep the moisture levels around the foundations relatively similar, thus any movement similar. no signs of damage could mean there's nothing to worry about, or it could mean teh vendor did a good job at hiding it before selling the property. Your first port of call would be to find out the soil type. Sandy soils tend to drain quickly and the impact on these of moisture is negligible (within reason), clays on the other hand expand and contract when y they get wet/dry. Depending on the type of clay, this can vary from moderate to extreme levels of movement. I know clays are common in QLD, but I wouldn't be making any guesses about yours. The bit that concerns me is the time it takes to drain, though with no evidence of damage after many years, its hard to say if you have an issue. If you're wanting further advice, a Geotech engineer can complete a soil report for you (~700-1500 bucks) which would give you the accurate information around whether you need to take additional precautions. In any case, a path around your home is usefull for many other purposes too, its worth it even just for quality of life. Thank you very much for your reply. I will try to find out the soil type and assuming it is not clay I will prepare to concrete withou rush. Thanks again.
