concrete bubble house without brick. Here's how: First, they lay down the foundation per the blueprints. Next, an air pump inflates a bladder, similar to blowing up a massive bubble, shaping the basic house model. Skilled workers then use a spray gun to apply concrete along the surface of the inflated bladder. Remarkably, this entire concrete-spraying process takes just one day. What's even cooler is that the internal bladder can be deflated and reused, showcasing an eco-friendly touch to this innovative construction method. #interesting #unique #interestingfacts #uniquefacts
