Underpinning is a process used in construction to strengthen and stabilize the foundations of existing buildings and other structures. It is the repair process that can give foundations their strength back after being weakened by different factors. Generally, the area under the building is focused on, repaired and reinforced so it is strong again. There are many types of underpinning and repair projects; the issue on your building will usually determine the approach your service provider takes to strengthen your building. But when should you really consider getting the underpinning services for your home, building or structure? geotechnical engineer
Your walls have cracks. Appearance of cracks in your walls is among the common signs that your building could be in need of underpinning. They may start off as small cracks and then progress into bigger cracks. Such cracks often start inside the building but it is also very possible for them to appear on the exterior. As soon as the cracks start bothering you, you should have them checked so the best underpinning solution can be given on time.
The property leans to one side. Visible leaning could only mean that there is something seriously wrong with your foundation of the soil underneath for that matter. It is a dangerous point, but when you get underpinning professionals as soon as you spot the line, then something can be done before things get worse. Keeping an eye on your property is very important because underlying issues can be tackled before they develop further.
Your windows and doors stick. Whereas temperature changes can interfere with a smooth closing and opening of doors and windows, especially those with wooden frames, if it is a problem you are just beginning to experience you should have it checked out. Usually, when the frames are no aligned properly, you will start having sticking doors and windows. If multiple doors on your property are routinely sticking and the issue was not there before, it is best that you get an expert to give their opinion just in case underpinning might be necessary.
The basement is showing changes. Moisture seepage, sinking into soil bed, extensive cracking are all signs that your basement could need underpinning. If it also seems to leak internal heat even after repairs, then you should get a second opinion with underpinning experts. Basement reinforcement could also be necessary when large buildings get constructed nearby and you notice large soil compaction below your basement or you just require more strength to carry additional weight when more floors are added.
You no longer have trust with original foundation. This could be because the building is old and you feel the foundation could be unstable as a result of decay of wood underneath it. It could also be that you lost trust in the strength because the usage of your building has changed and a stronger one is therefore necessary. Whatever your reason for feeling the foundation is no longer strong enough, it is best that you check with a professional so that the necessary underpinning can be done to save your structure.
