Decks that need piers or footings must have them installed below the frost line. This will keep the piers from heaving up out of the ground from the strength of the freeze. Reinforcing steel will help keep the piers from cracking.
Q&A /
Decks can be constructed out of many materials. My deck construction choices would be chemically treated pine for the structural aspect and construction grade redwood. This will look gorgeous in anyone's deck plans.
Building a ground level deck is not as hard as it seems. Ground level decks will need concrete beams to take the place of wooden beams that would be installed in a deck built off the ground.
Decks don't have to be made of wood only. You can find many types of alternative decking material. Virgin vinyl, recycled plastic, plastic resin mixed with wood fibers and aluminum. Sealing many of these materials is not necessary. Read this column to see the pros and cons.
Steel beams or columns will supply more support to a taller deck than wood can. These columns are easy to work with and connect simply under the deck. Making connections to the concrete piers is also an easy task. Painting the steel before installation will help with rust prevention.
