What concrete grade means?
Concrete grade is defined as the minimum compressive strength rating of a mix 28 days after it was poured.
How thick do I need to make a concrete slab?
Standard concrete floor slab thickness in residential construction is 4 inches. Five to six inches is recommended if the concrete will receive occasional heavy loads, such as motor homes or garbage trucks. To prepare the base, cut the ground level to the proper depth to allow for the slab thickness.
What are concrete slabs on grade?
Concrete slabs on grade are a very common type of concrete construction. Floor slabs can range from a simple residential basement slab to a heavy-duty industrial floor. However, no matter how basic or complex the floor is, the construction method is similar and includes; preparing the sub-grade and sub-base, placing
