We need to talk about concrete patios. Many homeowners in Manteca want a nice outdoor space for barbecues, for relaxing, or for just enjoying the Manteca sunshine. This is a good goal. But before you start pouring a concrete patio, or even picking out colors for your concrete patio, you need to know what to watch out for. Alpha Concrete has been doing this work for a long time here in Manteca, and our team has seen many people make mistakes on their concrete patio projects. The good news is that most of these concrete patio mistakes are avoidable if you know what to look for.
Ignoring Manteca's Tricky Soil
This is an important issue, and it is very specific to our Manteca area. We are in the Central Valley. This means we have expansive clay soils. What this means for your concrete patio is that these soils swell when they get wet. They also shrink when they dry out. It is like your backyard soil is constantly moving. If your concrete patio is not properly prepared for this soil movement, you will end up with cracks in the concrete patio. You will also have uneven surfaces, and this will cause many problems later on.
- Red Flag: A concrete contractor who does not mention soil testing or proper subgrade preparation for your concrete patio. Any contractor who just wants to clear the area and pour the concrete patio is cutting corners. You need a solid, compacted base for your concrete patio that can handle our local Manteca soil conditions.
- What to Do: Ask about their process for dealing with expansive soils in Manteca. Alpha Concrete, for example, always emphasizes thorough subgrade compaction. We also sometimes use specific measures like moisture barriers or deeper footings to counteract potential soil movement.
Skipping the Permits (or Not Understanding Them)
We understand that permits can feel like a hassle. But trying to build a concrete patio without a permit from the city of Manteca is a mistake you will regret. The city of Manteca has rules. These rules are there for a reason, for safety and for proper construction. A simple concrete patio slab that is not more than 30 inches above grade and is not over a basement might not always need a building permit. However, if you are adding a roof structure, or electrical, or plumbing to your concrete patio, you will absolutely need a permit.
