Render local block on every page

We are trying to add some functionality to our exsisting website. In this regard we need a local block on every page. I have created a block and have added it as property on PageBase class, this is the class which is inherited by every page. 

The problem i am having is how to render this block on every page without using @Html.PropertyFor(), on every page view.

public abstract class PageDataBase : PageData
    {
[Display(
            Name = "Test blok",
            Description = "",
            GroupName = PropertyGroupNames.xxx,
            Order = 1)]
        public virtual TestBlock TestBlock { get; set; }
//
//
}
