Pool Crack Repair: Spider Cracks on Fiberglass Pool Gelcoat

33h

The occurrence of spider cracks in fiberglass pools can be alarming to many pool owners. However, the problem with this is that they’re not very visible, even when the pool is emptied of water. This is why they’re not addressed immediately and are often left unchecked. If you’re wondering what exactly a spider crack is and how it forms, we have a brief guide on spider cracks right here for you.

What is a spider crack?

Spider cracks looks pretty much like hairline cracks and happen in the surface layer or gelcoat of a fiberglass surface. The term ‘spider crack’ comes from its similarity with a spider’s web. That is, the cracks emanate from a center point and radiates outward. These cracks are often small and do not affect large areas of the swimming pool and are mostly isolated to one small area in the pool.

Fortunately, most spider cracks do not pose an immediate threat to your swimming pool’s structural integrity. More often than not, spider cracks only affect the thin layer of gelcoat surface. It rarely goes or extend beyond the coating, thus not affecting the pool parts underneath or behind it. However, you may still want to contact a pool crack repair specialist and address the problem before it becomes worse.

What causes gelcoat cracks?

Spider cracks on gelcoat surfaces are usually the result of applying strong pressure in a portion of the gelcoat. Gelcoat is generally flexible, but when the pressure is too heavy, even gelcoats will start to crack. These undue pressure can be caused by a variety of sources.

For instance, improper handling can exert pressure on the gelcoat surface and can lead to spider cracks. Some gelcoats, especially the very thin ones are simply not capable of withstanding the pressure of lifting. When lifted incorrectly, this causes the gelcoat to bend at points where that are not supported and eventually crack. This is especially true in the case of low quality gelcoats.

But even if you have a good quality gelcoat, you can still see spider cracks due to poor installation practices. Protrusion in the swimming pool floors and walls like clumps of dirt or tree roots can exert pressure on the gelcoat and cause it to crack. This is why it’s important to hire only the right people when it comes to building your pool. This way you can be sure that the grounds are completely cleared before the construction. No reputable contractor would build a swimming pool until they are satisfied that the grounds are completely suitable for building.
