The Ultimate Pool Sealing Guide

Pool Sealing

Last Updated on July 8, 2023 by

The average swimming pool contains between 18,000 and 20,000 gallons of water. So, it’s easy to see how a small leak can soon become a big problem. Although your pool installer will go to great lengths to ensure their construction stays intact and leak-free for as long as possible. Yet, almost every pool will experience issues with leaks eventually. Pool sealing is the best way to repair these mishaps and ensure your pool stays watertight for years to come. 

What Causes Pool Leaks?

The structures that hold water inside your in-ground pool come into contact with both groundwater and chlorinated water inside your pool. These liquids gradually wear away at these concrete surfaces, leading to wear and tear over time.

An above-ground pool faces extra challenges from the sun’s rays, which will erode the plastic walls of the pool eventually. 

Broken plumbing is another major player in pool leaks. A leaking pipe quickly saturates the ground surrounding the pool, leading to further pressure on the pool wall.

Loose fittings can also cause leaks in the surroundings and cause major issues.

Sometimes small cracks in the tile or stone surrounding your pool can lead to deeper issues, too. A neutral pool tile sealer can help prevent these cracks from forming in the first place. 

Pool Sealing Basics

In most cases, your pool installer will treat your pool with a pool sealant that’s good for many years. You’ll usually only need to step in when you notice a leak forming in or near your pool.

These are some of the most common fixes when it comes to pool leaks:

Fixing a Leaking Pool Pipe Connection

This is a quick and easy fix using a silicone sealant and some Teflon tape.Simply unscrew the pipe and apply the silicone sealant to the ‘male’ surface. Wrap it with Teflon tape and put everything back together again.

If you suspect an underground leak, call a pool repair specialist. 

Fixing a Leak in Your Pool Liner 

You can fix a tear in your pool liner with a vinyl patch kit. You can buy these kits from a hardware store or pool supply store.

Simply choose the type of peel-and-stick waterproof patch you want and apply it according to the instructions.

Fixing a Crack in a Concrete Pool

Fortunately, these types of leaks are rare. You’ll need to ensure the offending area is clean and dry before you patch it, so empty your pool, so the water is below the crack before you get started.

You can use one of two types of sealant for your concrete pool. These are:

  • Epoxy – a two-part mix
  • Polyurethane Foam – an expanding foam

You can even use some types of epoxy underwater for added convenience, but this substance doesn’t swell like polyurethane foam, so it’s not suited to large cracks. 

Keep Your Home in Great Shape

Quick action can help stop your pool from leaking and prevent major issues stemming from pool leaks. So, check your pool regularly and apply a pool sealer at the first sign of cracks and leaks.
