How to Lay Concrete Blocks in a Pillar Under a Beam
Concrete beams are a structural element that you can add to the front of your house to replace wooden beams that are supporting a porch roof. To do this you will need to support the roof by using jack posts. Jack posts can also be used to raise the beam if it is not level. The beam for the roof will need to be level before constructing a concrete pillar. Materials for this project can be found at you local home improvement store. Does this Spark an idea?
