Concrete Pools: Three Fundamental Steps for Managing Delamination

Delamination is not an uncommon problem in swimming pools, and it is not unique to concrete pools. In general, this form of damage occurs when there is bond failure between the different layers of the structure, usually the main substrate of the tool and the upper surface. As a result, the layers separate, allowing for moisture penetration between the layers and subsequent deterioration of the pool surface.

In concrete pools, when delamination occurs, the plaster separates from the underlying foundation, and a void is formed in between. If the problem is not resolved, the plaster will rise and eventually, break. This will leave a hole in the pool, and the structural integrity of the entire unit will be compromised. Therefore, if you have noticed signs of delamination, use the outlined steps to conduct repairs.

Remove the Plaster

It is important to remove all the plaster affected by delamination for effective repairs. If you do not deal with all the damaged sections of your pool, you might need to conduct more restorative work within a short period. If there are broken areas with missing plaster, you will need to remove the damaged material from around the hole.

You should use a chisel to remove the surrounding material for effective repairs. It is also advisable to check for delaminated sections which are not yet broken. These areas are often popped up. You can also determine if a section of the pool is damaged because the plaster will be soft. If you find such areas, use a concrete grinder to cut out the affected section.

Clean the Surface

Cleaning the damaged parts of the pool before beginning the repair work is crucial. Remember, once the chunks of the old plaster are removed, there will be residue debris. The particles and general dirt will prevent bonding of the fresh plaster. Therefore, acquire a suitable tool to remove the debris. An air compressor or a vacuum will work well. It is also beneficial to prep the surface with an acid rinse. Be careful when handling the acid and rinse the pool.

Repair the Plaster

When the pool dries, you can proceed with the patching work. This process is quite straightforward. You will only need to prepare plaster or a suitable commercial patching product. Then, use the material to cover up the clean holes in the pool. Unfortunately, this simple process can be challenging. Preparing a perfect patch and matching the original texture is difficult for amateurs. Therefore, if you are not certain, consult an concrete pool contractor.

Pool Maintenance Through The Seasons

When we purchased our latest home, we were finally able to deliver on a long-promised pool for the kids. However, we had never had a pool before, so that first year was a huge learning curve in keeping it clean and not green! After teaching ourselves so much about pool maintenance and the way it changes throughout the year, I decided to gather all my information and put it into a blog for other first-time pool owners. Once you get a pool maintenance schedule going, you never have to worry about losing swimming days because of a dirty pool. So, have a look at my blog posts, and educate yourself how to keep your pool clean.
