Expansion Joints and deck cracks! Why should you care?
Most people think the spaces between their concrete deck is just that, spaces. Not true, these are expansion joints there for the expansion and contraction of the concrete in hot and cold days allowing your concrete slabs to move independently without cracking.
These joints are generally filled with a pliable substance called mastic. Sometimes the pool installer puts in deck strips that are plastic white pieces that are designed to be removed and filled with mastic, as step that sometimes is forgotten. This causes the deck strips to become brittle and ugly. Additionally mastic seals the joint so ants and plants don't grow between the concrete deck slabs.
You need to evaluate your deck and see if you have issues of compromise to the joints. These mastic joints are generally replaced about 3 to 5 years depending on cracking and sun exposure.
Property managers for apartment houses and public pools, malls and shopping centers as well as professional building should look into mastic against the buildings and in the walkways. The mastic maintenance is critical for your high healed patrons where law suits can be avoided from the cracks and twisted ankles.
