Many factory owners who want to expand their facility worry that their existing old building foundation is not strong enough to support the weight of new traditional masonry walls, which would force them to spend huge amounts of money on expensive foundation reinforcement work. The EPS Cement Sandwich Panel completely eliminates this problem, because its ultra-lightweight design lets you add new expansion sections to your existing factory, using your original foundation without any major upgrades. A standard EPS Cement Sandwich Panel weighs less than 15kg per square meter, which is 1/10th the total weight of a traditional brick wall of the exact same size. This extremely low dead load puts almost no extra stress on your existing foundation structure. Even if your factory was built 30 or 40 years ago, and was not originally designed to support heavy new wall loads, it will almost certainly be more than strong enough to support these lightweight panels. This saves you a huge amount of money on structural engineering costs, foundation excavation work, extra concrete pouring and steel reinforcement that you would need if you used traditional wall materials. You do not have to dig up large sections of your existing factory yard, disrupt your ongoing production, or spend weeks doing messy foundation construction work. You can simply lay a thin new layer of leveling concrete on top of your existing foundation slab, and start installing the EPS Cement Sandwich Panel walls immediately. This cuts your total expansion project timeline by months, and removes one of the most common and expensive hidden budget overruns that happens on factory expansion projects. Even if you are adding multiple new levels or a mezzanine structure on top of your existing factory, the low weight of the panels means your original structure can easily support the new walls, without any major structural modifications. This makes expanding an old existing factory far more practical and affordable than almost anyone expects. You do not need to demolish your entire old factory and build a completely new facility just to get extra space. Using the EPS Cement Sandwich Panel, you can safely, affordably and quickly add all the new production, storage and office space you need, making full use of the strong existing foundation and structure that you already invested in decades ago.
