pool support

Pools are significant investments, and when the ground around them starts to shift, the consequences can be expensive and stressful. A settling pool deck creates trip hazards. Cracking around the pool shell can lead to leaks. And if the pool structure itself shifts, the repair costs escalate quickly.

Pool settlement is especially common in the Lower Mainland because many pools are built on fill material that compacts over time, or on clay soils that expand and contract with seasonal moisture changes. The heavy weight of the water, combined with the constant wet-dry cycling of the surrounding soil, creates conditions that challenge even well-built pool installations.

The tricky part about pool settlement is that it often happens gradually enough that you don’t notice until the damage is significant. The pool deck develops a slight slope. Coping stones start to separate. The water line looks uneven against the tile. By the time these signs are obvious, the movement has been progressing for some time.

At Ossum, we use Ram Jack® steel pier systems to stabilize pool structures and decks on permanent foundations. Rather than trying to patch the symptoms, we address the soil problem underneath by transferring the load to stable bearing strata. This stops the settlement and, in many cases, allows us to lift settled sections back toward their original position.

Pool support projects require careful planning because of the water, plumbing, and electrical systems involved. We work with your pool contractor to coordinate the work and ensure nothing is disrupted. Our goal is to stabilize your pool investment permanently so you can enjoy it without worrying about what’s happening underground.

Signs You Need This Service

Watch for these warning signs that indicate you may need professional foundation support:

Pool deck sinking or sloping

When the concrete deck around your pool starts to settle unevenly, it creates trip hazards and allows water to drain toward the pool in ways the original design didn't intend. You might notice puddles forming in new areas or a visible slope that wasn't there before.

Coping stones separating or cracking

The coping stones along the pool edge are designed to sit flush and tight. When they start to separate, crack, or shift position, it's because the underlying structure they sit on has moved. This is both an aesthetic and safety issue.

Cracks in the pool deck concrete

New cracks appearing in the pool deck, especially ones that seem to grow over time, indicate the soil beneath is settling. Watch for cracks that are wider at one end than the other, as these show the direction of movement.

Uneven water line in the pool

If the water level looks higher on one side of the pool than the other, or the tile line appears crooked, the pool shell itself may have shifted. This is a sign that the settlement is affecting the pool structure, not just the deck.

Pool plumbing leaks

Settlement can crack or separate plumbing connections around and beneath the pool. If you're losing water faster than normal evaporation would explain, or noticing soggy areas in the yard near the pool, the plumbing may have been stressed by ground movement.

Gaps between pool and deck

A gap opening between the pool shell and the surrounding deck is a clear sign that one or both have settled at different rates. This gap allows debris and water to collect beneath the deck, which can accelerate further settlement.

Our Process

0

Pool and Deck Assessment

We evaluate the pool deck, structure, and surrounding soil conditions. Elevation measurements identify exactly where and how much settlement has occurred. We also coordinate with your pool contractor to understand the plumbing and electrical layout.
1

Engineered Support Plan

Based on the assessment, an engineer designs a pier layout that provides permanent support for the affected areas. The plan accounts for the pool's weight (filled with water), deck loads, and the specific soil conditions on your property.
2

Pier Installation

Piles are installed at the engineered locations around the pool deck and, where needed, alongside the pool structure itself.
3

Stabilization and Lift

Once all piers are installed and verified, settled sections are stabilized and, where possible, lifted back toward their original position. Deck sections, coping, and connections are restored to proper alignment.
4

Completion and Restoration

The work area is cleaned up and restored. We provide documentation of the repair for your records, including pier locations and engineering sign-off. Your pool contractor can then address any cosmetic finishing work with confidence that the structure is sound.

Systems & Solutions

Ram Jack® Helical Piles

Helical piles are the preferred solution for pool support because they can be installed precisely around the pool area without the vibration that could stress the pool shell. Each pile is torque-verified during installation to confirm it's reached stable bearing soil, providing permanent support for both the deck and pool structure.

Engineered Brackets

Engineered brackets designed for pool applications connect the helical piles to the pool deck and surrounding structures. These brackets distribute the load evenly and allow for precise adjustment during the stabilization and lifting process.

Frequently Asked Questions

Does the pool need to be drained for repair work?

In most cases, no. The majority of pool support work involves the deck and surrounding structures, which can be repaired while the pool remains filled. If the pool shell itself needs to be addressed, partial or full draining may be required, but we’ll discuss this during the assessment.

Can you repair a pool deck without replacing it?

Yes. Our approach stabilizes the existing deck from below using steel piers, then lifts settled sections back toward their original position. This preserves your existing deck rather than tearing it out and starting over, which saves significant cost and disruption.

How long does pool support work take?

The timeline depends on the number of piers required and the complexity of the pool area. We schedule the work to minimize impact on your pool usage.

Will the repair prevent future settlement?

Yes. The piers transfer the deck and pool structure loads to stable bearing soil below the surface, bypassing the problem soils that caused the original settlement. Our 20-year warranty covers the pier system against future settlement.

What causes pool deck settlement?

The most common causes are poorly compacted fill material placed during pool construction, clay soils that expand and contract with moisture changes, and erosion beneath the deck caused by water runoff or pool splashing. The heavy weight of the water in the pool also contributes to settlement of surrounding soils over time.

Why Professional Support Matters

Mudjacking or foam injection can temporarily raise a settled pool deck, but these methods don’t address the underlying soil problem. The settlement typically returns within a few years because the soil underneath is still unstable. Engineered steel piers reach stable ground below the problem zone and provide a permanent solution that won’t need to be repeated.
