Assembling an internal drainage container house from scratch is a practical modular construction project with complete waterproof design. We start by fixing the galvanized steel frame and splicing wall panels strictly according to assembly drawings. The core highlight lies in the built-in internal drainage system: hidden drainage grooves are pre-installed under the roof and floor, guiding rainwater to concealed pipes instead of overflowing outside, which avoids wall dampness and water stains.
Next, install doors, windows, thermal insulation and interior decoration. Every pipe joint is sealed tightly for leakproof performance. The whole process requires only basic hand tools without heavy machinery. This container house boasts neat appearance, stable drainage and long service life, ideal for villas, offices and temporary camps. DIY builders can finish assembly within several days following standardized steps.
