Repairing Concrete Pool Coping Repairing Concrete Pool Coping

Concrete pool coping refers to the upper part of the swimming pool’s edge. Swimming pool coping is used to cap off the pool walls. Most concrete coping is pre-cast, although some pools have coping made from tile or stone as well. Over time, the concrete coping on your swimming pool may become worn, damaged or loose. When this occurs, it is helpful to know the costs and methods of repairing concrete pool coping.

What to do if your Coping is Dirty or Worn

One of the most common problems with concrete pool coping is dirty and exposure damage. If the dirt is localized or has not been deeply set into the concrete, scrubbing with a brush and soap may suffice. However, if the situation is more serious, consider using a chemical concrete cleaner or an acid solution. These cleaners are available at hardware and pool supply stores. When cleaning your pool with a chemical cleaner, it is important to follow all application instructions and to wear proper safety equipment at all times.

Chemical pool cleaners work by stripping away the surface layer of the concrete, effectively eliminating any dirt or worn areas. These chemicals are damaging to the skin and must be used with care. Additionally, if applied improperly or spilled, they will cause acid damage to other parts of the pool surface.

What to do if your Coping is Loose

If the coping at the edge of your pool has come loose, it may be due to expansion of water that is trapped in the area between the deck around the pool and the expansion joint of the pool coping. When water in this space cools or freezes, it damages and loosens the coping due to expansion.  In this case, thoroughly caulk the expansion joint of the pool coping.

Loosening may also occur if the expansion joint is out of alignment. Ensure that the expansion joint itself is set up properly, according to the installation instructions. If the expansion joint becomes reoriented, it may cause damage to the pool coping when the temperature changes.

How to Deal with Cracks in your Pool Coping

Over time, wear and tear as well as exposure may cause the concrete of your pool coping to crack. Depending upon the size and location of the crack, this may or may not be a serious concern. If the crack is large enough that water may enter, take preemptive action and seal the crack using concrete sealant. If left untouched, cracks of this size may collect water. If this water freezes or cools significantly, it too will expand, enlarging the crack and causing further damage to your coping.

If you have further questions regarding the repair or replacement of your pool coping, contact a swimming pool supply store or professional pool repair service. It is best to act quickly if your coping is damaged, because many of the most common problems related to swimming pool coping become exacerbated if left untouched.
