Yes, you can lay a four-inch slab over an existing slab, but proper preparation is essential. The existing slab should be clean, free of debris, and in good condition to ensure a solid bond. It's also recommended to use a bonding agent and to reinforce the new slab with steel rebar or wire mesh to prevent cracking. Additionally, ensure that the new slab's thickness and weight won't compromise the structural integrity of the underlying slab.

Can you pour a concrete slab onto another concrete slab?
No. Concrete won't bond to concrete. It will end up cracking.
How do you install water lines in a slab home?
You have several choices but none of them are perfect. One choice is to have a hole bored horizontally underneath the slab and then a vertical hole through the floor to join it. A second choice is to have a concrete cutter saw a channel in your slab, lay the pipe, and then fill in concrete over it. Another choice is to have the pipes come in through the wall above ground level rather than go through the slab. The last choice is to go up. The pipes go up the outside wall and through the ceiling, dropping down from the attic into a wall. This can be a noisy option unless the pipes are properly secured and insulated. Don't go cheap. Go with copper piping big enough that you won't regret it later. No half inch pipes! Stay with 3/4 or larger inside with one inch or larger mains.

How do you get the formula 80 for 4 inch slab?
To calculate the formula for a 4-inch concrete slab, you typically convert the thickness from inches to feet by dividing by 12. A 4-inch slab is 4/12 = 1/3 feet thick. When calculating the volume (cubic feet) for a slab, the formula is Volume = Length × Width × Thickness. If the slab covers an area of 80 square feet, multiplying that area by the thickness (1/3 feet) gives you 80 cubic feet.
