If the existing concrete is structurally sound is not heaving or settling then you can pour concrete over concrete.
Can you put stamped concrete over existing concrete.
Pouring concrete over an existing concrete driveway or sidewalk.
The same principles as above apply to pouring concrete over an existing concrete driveway or sidewalk.
If the new concrete is 3 inches thick or more you don t have to bond the new concrete to the old concrete.
My rule of thumb is this.
You just have to consider the added height.
Apply a bonding adhesive over the existing patio and a thin coat of bond release agent over the stamps so they don t stick to the concrete.
Aesthetically you can end up with the same coloring and texture that mimics the look of brick stone marble or whatever texture you re after on a newly poured thicker slab.
Installing a stamped concrete patio over an old surface is a two part process.
If you appreciate the functionality but want to add style to an existing concrete slab you can stamp new concrete overlay over the surface.
First you pour the new concrete then you press the stamps.
With some supplies and a full day of dedicated labor you can transform an otherwise plain surface.
You can if the concrete is sound solid with minor cracks pitting scaling surface damage or just plain ugly.
Concrete slabs provide strong surfaces that withstand years of wear and tear with little maintenance.
If done properly new concrete can often be poured right over an existing slab.
For this to be feasible the contractor needs to pour at least 2 inches thick use smaller aggregate and incorporate reinforcement such as welded wire mesh or fiber mixed into the concrete.
