This is a rare steel-framed house structure. All studs, beams, posts, and ceiling joists are prefabricated and brought to the site. All material is assembled on-site giving this particular house a very strong and energy-efficient
nature. Bottom line, a very well built house but a higher cost to build.
This is a video clip from one house that was inspected. It was raining heavily that day and the water table was very high. The pressure of the water was actually flowing in through the point of least resistance, which in this case was the slab floor, into the basement through the old condensate drain next to the furnace.
Clearly the weeping tile around the house was in poor condition. The house needed a sump pump and pit to eject the water out from the house. Over time, such water intrusion can have a considerable impact on the foundation of a house and all the materials within the basement that would promote mould growth.
