How to Level a Concrete Pool Deck: Methods, Costs, and What Works Best

This is What You Should Know Before Leveling a Pool Deck

An uneven pool deck is more than just an eyesore. When concrete around a swimming pool begins to sink, shift, or settle unevenly, it can create trip hazards, drainage problems, and potential damage to surrounding pool features.

Many homeowners assume that once a pool deck becomes uneven, replacement is the only option. Fortunately, that is not always the case.

In many situations, a concrete pool deck can be leveled and stabilized without tearing out and replacing the entire slab. The best repair method depends on what caused the settlement, how much movement has occurred, and whether the existing concrete is still structurally sound.

If you’re wondering how to level a concrete pool deck, here’s what homeowners should know before deciding between repair and replacement.

Why Pool Decks Become Uneven

Most uneven pool deck problems, especially in New Jersey towns, begin beneath the concrete rather than on the surface.

Over time, water can wash away supporting soil beneath the slab, creating empty spaces known as voids. Once the concrete loses support, sections of the pool deck may begin to sink, tilt, crack, or separate from neighboring slabs.

Common causes of pool deck settlement include:

• poor drainage around the pool
• soil erosion beneath the slab
• freeze-thaw cycles during winter
• improper soil compaction during construction
• pool plumbing leaks
• open joints allowing water infiltration
• long-term moisture exposure

Can You Level a Pool Deck Without Replacing It?

Yes. In many situations, pool deck concrete can be successfully leveled without full replacement.

The determining factor is usually the condition of the existing slab. If the concrete is still structurally sound and the primary problem is settlement, leveling may be a practical solution.

Pool deck leveling is often possible when:

• the slab has settled unevenly
• trip hazards have developed
• water pools in low areas
• voids have formed beneath the slab
• the concrete remains largely intact
• cracks are limited and repairable

Many homeowners are surprised to learn that repairing uneven concrete can often be more practical than replacing it entirely. In fact, many cases of settlement can be corrected through repairing cracked pool decks instead of replacing them.

Methods Used to Level a Concrete Pool Deck

Several repair methods may be used to correct uneven concrete around a swimming pool. The right approach depends on the condition of the slab and the underlying cause of the settlement.

Mudjacking

For many pool decks, mudjacking is one of the most effective ways to lift settled concrete.

During the mudjacking process, a specialized material is pumped beneath the slab to fill voids and raise the concrete back toward its original position. This helps restore support beneath the slab while reducing uneven areas and trip hazards.

Professional mudjacking and concrete leveling can often restore existing pool deck concrete without the disruption associated with demolition and replacement.

Mudjacking is frequently used when:

• the concrete has settled because of soil erosion
• voids have formed beneath the slab
• the pool deck remains structurally sound
• the homeowner wants to preserve existing concrete

Polyurethane Foam Injection

Some contractors use polyurethane foam injection to raise settled concrete. This process involves injecting expanding foam beneath the slab.

While foam lifting can be effective in some situations, the appropriate solution depends on the condition of the concrete, site conditions, and repair objectives.

A qualified contractor should inspect the slab before recommending any lifting method.

Concrete Grinding

Concrete grinding is sometimes used when one slab edge sits slightly higher than another.

Grinding removes a portion of the concrete surface to reduce the height difference. However, grinding does not address settlement beneath the slab and does not restore support underneath the concrete.

If the real problem is soil erosion or void formation, the slab may continue moving after grinding is completed.

Full Replacement

Replacement is generally reserved for situations where the concrete is severely damaged or no longer structurally repairable.

Signs replacement may be necessary include:

• major structural deterioration
• multiple broken slab sections
• severe surface failure
• extensive cracking throughout the deck
• poor original installation

However, replacement should not automatically be considered the first option simply because a pool deck has become uneven.

Can You Level a Pool Deck Yourself?

Many homeowners search for ways to level a pool deck themselves after noticing settlement around their pool.

While some minor maintenance tasks can be performed by homeowners, lifting settled concrete is generally not a typical DIY project.

Successfully leveling a pool deck requires:

• determining why the slab settled
• identifying hidden voids
• evaluating slab integrity
• understanding soil conditions
• using specialized lifting equipment

Attempting to lift a settled slab without proper equipment can result in additional cracking, uneven lifting, or further damage.

Homeowners can help reduce future settlement by monitoring drainage, sealing joints, and following the recommendations outlined in our guide on how to prevent expensive pool deck repairs.

When Concrete Leveling Is Better Than Replacement

One of the biggest misconceptions homeowners have is assuming replacement is always the better solution.

In reality, concrete leveling may offer several advantages when the slab is still repairable.

Potential benefits include:

• less disruption around the pool
• faster project completion
• preservation of existing concrete
• correction of trip hazards
• restoration of drainage patterns
• elimination of voids beneath the slab

Professional pool deck leveling and repair is often worth considering before committing to a full replacement project.

How Much Does Pool Deck Leveling Cost?

The cost of leveling a concrete pool deck depends on several factors, including:

• the amount of settlement
• the size of the affected area
• the number of slabs involved
• accessibility around the pool
• whether void filling is required
• the overall condition of the concrete

In many cases, leveling existing concrete is less expensive than demolition and replacement.

Pool Deck Leveling Case Study in New Jersey Towns and Cities

Uneven pool deck concrete is a common issue throughout New Jersey communities where moisture, seasonal weather conditions, and soil movement contribute to long-term settlement.

Homeowners in Holmdel, NJ, seeking concrete leveling services often discover that uneven concrete around a pool is linked to voids beneath the slab or to years of gradual soil erosion.

Addressing these problems early may help prevent additional cracking, larger trip hazards, and more extensive repairs later.

We recently documented the repair of a sunken pool deck for a client in Holmdel, demonstrating that settled concrete can often be restored without complete replacement.

Signs Your Pool Deck Should Be Evaluated

If you’re unsure whether your pool deck needs leveling, there are several warning signs worth watching for.

• trip hazards between slabs
• standing water after rainfall
• visible settlement around the pool
• widening cracks
• separation near expansion joints
• pool deck sections that tilt or slope unexpectedly
• hollow sounds beneath concrete

These symptoms often indicate underlying support issues that should be addressed before the settlement worsens.
