Contamination can occur through a variety of avenues, but the main concern when dealing with contaminated concrete (outside of the environmental issues) is whether the structure is still sound. What do these leaks or spills do to the concrete below them?
Wood Truss Repairs - Determining the Best Option
Today, wood trusses are the most common way to frame the roof on a wood-framed building. They offer a high weight-to-strength ratio, long spans, good speed of installation, and a multitude of possibilities for the shape of the roof and the ceiling underneath. Wood trusses can be engineered to span over 25 m (80 ft), and buildings that require large clear spans, such as farm buildings, can also be accommodated.
The Effects of Vibrations on Buildings
