Don’t put off getting your pool deck redone!

At the Decorative Concrete Experts, we get very busy this time of year and are often asked if we can complete a job before a major holiday.  The call volume goes up a week before Spring Break, Easter, and Memorial Day.  The problem is that we are generally scheduled out for two to three weeks. Additionally, some pool decks take almost a week to complete.  With just about every service that we offer excluding a simple repaint, the deck needs to cure for as much as five to seven days before heavy use.  We stay very busy because we do great work at a fair price.  If you do have a tight deadline, we will do our best to complete the pool deck in the time alotted, but we can do a better job and work with less stress by scheduling the work well in advance.  Don’t get stuck with a contractor that isn’t busy for good reasons.  With that said, we have a crew out today on a pool deck repaint that was signed yesterday so that the customer has the area ready for an Easter party next weekend.

Cracks in concrete

Cracks are unfortunately a common but preventable occurrence in most concrete surfaces.  The vast majority of cracks are due to the lack of planning for expansion joints when the concrete is initially installed.  A qualified concrete contractor should have a plan in place before any concrete is poured to control any possible cracking issues with expansion joints.  There are plastic joints that are commonly used on pool deck surfaces, but a simple saw cut is just as effective and isn’t sensitive to UV rays over time.  To be effective, the saw cuts must be made systematically in weak areas where the concrete is most likely to experience a stress crack.  The number of joints necessary depends on a number of factors including the thickness of the slab, specific mix of concrete used, the type of reinforcement used, and the layout of the slab.  For a saw cut to be effective, it needs to be at least 1/3 through the thickness of the slab.

Based on my experience in Orlando, it is rare to come across a pool deck that was poured with a sufficient number of expansion joints.  The plastic joints are most common and usually their placement isn’t ideal for preventing cracks from forming.  The common result is a pool deck with lots of unsightly cracks.  For the most part these cracks are harmless and are merely a cosmetic issue.  There should only be concern if the slabs are shifting (one slab  is lower than the other).  How we treat the cracks depends on what we are planning to do to the surface.  For a simple repaint on an acrylic pool deck, the best course of action is to seal the cracks before painting the surface.  This makes the crack less noticeable, prevents erosion, and keeps insects out while allowing the concrete to naturally expand and contract with temperature fluctuations.  When we are applying an overlay, the best course of action is to open the crack up and inject a high strength epoxy that works to prevent the crack from appearing in the new surface.  Unfortunately, in some situations the natural forces of expansion and contraction are too much and the structural epoxy cannot hold.

It is a common misconception that most concrete cracks due to settling.  Regardless of how long the concrete has had to settle, there will be movement along a crack due to the natural expansion and contraction of the concrete that occurs with temperature change.  It’s also a common misconception that cracks form because wire mesh or rebar wasn’t used.  In many situations, the reinforcement actually causes the initial cracking.  This happens because of the concrete trying to contract as it cures while being constrained.
