Building an outdoor living space and pool area on a hill, in a valley, or on terrain that doesn't have stable soil can be a problem. You can still get the outdoor area that you want, but you will have to invest the time to have the design engineered properly and the money to have the ground reinforced as needed.
Once you have chosen the layout for the concrete patio and design for the pool and any entertaining areas, your contractor will map it out in the yard. From there they will determine how far they need to go to retain and stabilize the soil. Be ready to consider these things.
Soil Stabilization Options
Stabilizing the soil will be a very important part of the process if you want the patio, pool and outdoor living space to stay in place. The concrete professionals may bring in some sand and gravel to go under where the concrete will be laid.
There are chemical treatments that can also be used in the soil to help make the ground more firm and to change its pH. Talk with the concrete contractors to find out which options are the best for you.
Retaining Wall Choices
A retaining wall is another option to help keep the soil in place as needed. You can look at a variety of different concrete options, and the contractors may want to use metal beams or sheeting to help keep everything reinforced so it stays in place.
This isn't just going to help to reinforce the outdoor living space that you want to create, but it can be good to prevent shifting and movement within the foundation around your home as well. Get estimates and look at walls that are already completed so you can envision what the wall will look like on your property.
When you are trying to build on land that isn't stable and that may have some flaws and potential problems, you will want to make sure that you hire qualified concrete contractors and land surveyors as needed. You don't want to spend a lot of money on all the materials and labor hours to create your outdoor space, and then find out that the improvements aren't going to last or have potential problems. Get quotes and look at design layouts from different contractors in your area, to find the best layout and choice for your property.
