Our new modular house is going to sit on Precast Concrete Walls from Ideal Precast. The walls are guaranteed waterproof, factory built in panels that are put together on site. They come with insulation already attached and ready to finish from inside with no need for any additonal framing. The first picture is at 9:00 am showing the gravel base that the walls sit on.
Stay tuned for more details on Precast walls and more pictures of the walls.
