I m installing a patio in my backyard and the grade level is about 15 in.
Concrete patio against wood siding.
If so 1 2 inch or more.
Im having concrete steps poured against the house under patio doors.
This means that you can lay the pavers against the concrete of your foundation as it rises from the earth.
Pavers against these areas can cause rotting issues and blocked airflow problems over time.
Should there be a gap between house and concrete steps to allow air flow.
Approx 3 ft in height.
Below the sliding patio doors so there needs to be a step.
Im installing pressure treated plywood then house wrap around plywood and metal lath.
Ok now look at the concrete foundation.
How to safely pour concrete against siding.
That right there just lopped of 9 inches.
1 i see about 18 inches of siding.
There s currently a piece of wide fiber cement trim that covers the rim.
The plan is to build the step out of concrete and top it off with a limestone cap.
3 i would presume you will have a 5 inch step into the house.
I would advise locating a vinyl siding company and getting them to break some scraps that they ve laying around about an inch much higher than the concrete will be poured and as far out from the house as the scraps will go.
Is this enough to protect the plywood from rot.
If you find your plans require laying pavers against vents siding or other materials choose another patio plan.
