Floating Slab Roof

Determine the height of the top surface of your concrete slab.

Floating slab roof.

Floating slabs are concrete slabs that are laying over the ground without any kind of anchoring as if it simply sits on it and floats. Floating slab is sometimes known as a raft foundation and they are generally constructed on soil with high proportions of sand water or clay. Small sheds and backyard structures like gazebos and pergolas may not need elaborate foundations because they are so light. How to build a floating slab step 1.

The idea being let the original concrete slab crack and do what it wants because the upper slab will float on top undisturbed. Determine the area to your floating slab and then mark the four corners with 3 feet metal stakes. A floating slab spreads the structure weight over the entire base instead of at strategic supporting columns. Once you ve made this determination use string to mark.

After much deliberation we decided to top the cracked concrete with a new floating slab. Applications and advantages of floating slabs are discussed. Measure out two feet in the perimeter laterally and mark off this area. As they are shallow in depth they can ideally be used in specific construction locations.

This presented a problem of how to remove the concrete pad and still hold up the roof. Play pause space step 2. Adding to a floating slab building most buildings need foundations to transfer the structure s weight as well as roof and floor loads into the ground. Determine the height of the top surface of the concrete slab.
