Unlike a pier and beam system which requires fairly regular maintenance a monolithic slab doesn t require you to do any upkeep As long as you give it an inspection at regular intervals to ensure there aren t cracks in the foundation

THE MONOLITHIC SLAB CONSTRUCTION PROCESS In addition to being poured in one step monolithic foundations are also significantly thinner than a traditional foundation They average only four inches thick and the footings only reach about 12 inches from the base to
The insulation around the foundation perimeter conserves and redirects heat loss through the slab toward the soil below the foundation Geothermal heat from the underlying ground also helps to warm the soil and raise the frost depth around the building Frost protected shallow foundations are most suitable for slab on grade homes on sites with
FOUNDATION REQUIREMENTS All exterior walls marriage walls marriage wall posts columns and piers must be sup ported on an acceptable foundation system that must be of sufficient design to support safely the loads imposed as determined from the character of the soil A Height Above Grade Foundation walls shall extend at least 8 quot above the finished grade

2010 11 11 nbsp 0183 32 Now that minimum energy code requirements for slab insulation have overtaken the design requirements for a frost protected shallow foundation the line between a conventional slab on grade foundation and a frost protected shallow foundation has been blurred As a result almost any monolithic slab complying with energy code requirements
If the slab has hydronic tubing the minimum R value of this insulation increases to R 15 The same R value requirements apply in climate zones 6 7 and 8 but the insulation must extend to a depth of at least 4 ft What happens if the

In 1981 DESIGN OF SLAB ON GROUND FOUNDATIONS A Design Construction amp Inspection Aid for Consulting Engineers was first published The design procedure set forth in that publication had at that time been in use by the author for about 15 years After this publication it was subsequently adopted by the Uniform Building Code UBC as Standard 29 4 I Copies of
