How to Repair a Swimming Pool

Families and friends come together around swimming pools during the summer to cool off, participate in watersports, and gather for social events. Cracks in pools can occur from harsh winter weather, a bad pool installation, and normal aging, causing concern to owners when leaks require constant refilling of the pool or present a safety hazard to swimmers. However, owners can make repairs to the cracked concrete of in-ground pools, cracked fibreglass pools, fractured gunite pools, and snags and tears in vinyl pools with a little knowhow and the proper supplies for the job. Consumers can find the products necessary to restore a pool locally at pool shops or on eBay.

Determine the Pool Type

Before repairing a pool, owners should determine the material used to construct the pool, such as concrete or gunite.

Type of Pool


Concrete In-Ground Pool

Formed using poured concrete construction

Fibreglass Insert Pool

Fibreglass form inserted into the ground

Gunite Pool

Formed using sprayed concrete, sand, and water construction

Above Ground Vinyl Pool

Owners should know their type of pool construction to ensure they perform the correct repairs for their pools' needs.

How to Repair Concrete Pools

Indicators that a pool is leaking can be loose tiles, soggy soil around the perimeter of the pool, a daily 6 cm reduction in the pool's water level, and leaks around the filter, valves, drains, and fittings.

How to Repair Concrete Pool Chips and Cracks

To repair concrete chips and cracks, cut a 25 mm edge on all sides of each crack about 12 mm deep with agrinder. Run a soft bristle brush over the area, and then wipe with a soft cloth. Use waterproof caulking to fill in the crack, leaving a 6 mm edge for the pool patch. Once the caulking dries, wet a sponge, and moisten the patched area. Fill the remaining surface with pool patch cement using a putty knife to even out the cement. The patched area should stay wet until the cement cures.

How to Repair Fibreglass Pools

A fibreglass insert fits into a hole to create an in-ground pool that can crack if the ground shifts or the fibreglass pool ages. Be careful when draining fibreglass pools since removing too much water puts strain on the fibreglass structure due to the earth berm surround.

How to Repair Fibreglass Pool Cracks

Sand the crack with medium grit sandpaper and cut a perimeter around the crack using a grinder saw. Apply epoxy from a fibreglass repair kit using a paintbrush, and then fill the crack with putty using a trowel.

Use duct tape to create a border around the crack, and paint the entire area with gelcoat. Remove the duct tape, and place fibreglass fabric over the entire damaged section, extending outward on all sides a distance of 50 mm. Finish by coating the fabric with gelcoat, press out air bubbles, let the patch dry, and sand the patched surface.

How to Repair Gunite Pools

Gunite tends to contract and expand, causing cracks to the porous material. Drain the pool and remove any dirt with a small broom. Expand the size of the crack with a diamond-bladed grinder, and wipe away dust using a microfibre cloth. Combine a mixture of three parts cement, two parts sand, and one part water in a bucket. Apply caulking with a putty knife to the crack, and cover the area completely with the cement mixture, letting it dry thoroughly.

How to Repair Vinyl Pools

A vinyl repair kit usually contains glue and clear patches to repair vinyl pools and liners. Clean the tear area so the patch sticks permanently to the vinyl. Cut a patch twice the size of the tear, allowing for equal room on all sides, and round the corners with scissors. Put glue on the patch and position it, working from the centre to the outside, remove air bubbles, and allow it to dry.
