Pool-Deck Polyjacking & Concrete Lifting in Northern Virginia
A focused approach to lifting settled concrete around your pool. We evaluate the slabs, nearby plumbing and drainage before planning a controlled polyurethane lift.
Request an on-site evaluation to confirm suitability, scope and pricing.
A Deck Specialty Shaped by Pool Construction Experience
Polyjacking raises settled concrete by injecting polyurethane foam beneath the slab. Around a pool, that work happens inches from buried return lines, skimmer throats, main-drain plumbing, coping, and the expansion joint—components a generic concrete crew may not understand.
The Pool Sharks brings more than 30 years of gunite pool construction, remodeling, and service experience to the evaluation, so the injection plan accounts for what sits beneath and beside the deck—not just the surface.
Why Plumbing, Coping & Drainage Matter
- Buried plumbing: Return lines, skimmer throats, and main-drain runs sit under the deck. Injection must be planned to avoid those circuits.
- Coping & expansion joint: Settlement pulls the deck away from the coping and opens the joint, letting water reach the pool beam and soil beneath.
- Skimmers & drains: Nearby skimmers and buried plumbing need careful consideration during the lifting plan, so injection avoids loading those circuits.
- Drainage: Lifting can improve pitch, but it does not guarantee perfect drainage; surface runoff and soil conditions should be evaluated alongside the lift.
Signs Your Pool Deck May Have Settled
Around a wet surface, even a small elevation change becomes a real trip hazard. These are the signs an on-site evaluation can confirm.
Settled vs. Supported
A simple look at what a settled slab above a void looks like compared with a slab supported after a controlled polyurethane lift.

A Compact, Planned Approach
We evaluate first, then plan injection around the pool’s buried components before any foam goes in.
Evaluate suitability
An on-site evaluation confirms whether the slab is a candidate for lifting. Severely shattered or structurally failed concrete may call for replacement instead.
Plan injection around buried lines
Because The Pool Sharks builds and services pools, the injection plan accounts for buried plumbing, skimmers, main drains, coping, and nearby structures—not just the slab surface.
Controlled foam lift
Small holes are drilled and polyurethane foam is injected beneath the slab. The foam expands to fill voids and gently, controllably raises the slab toward the intended elevation.
Patch and inspect
Injection holes are patched to blend with the surrounding concrete, the lift and drainage pitch are reviewed, and the area is cleaned up.
Lifting vs. Replacement
Lifting is often the lower-disruption option, but it isn’t always the right one. Here is an honest comparison.
Polyurethane Lifting
- No full demolition or repour
- Small injection holes, less disruption
- Fills voids beneath the slab as it lifts
- Best when the slab is largely intact and the cause is addressed
Full Replacement
- Severely shattered or structurally failed slabs
- Heaved slabs from tree roots that must be removed
- Surfaces too deteriorated for lifting to restore appearance
- We give an honest recommendation after the evaluation
Lifting makes the settled deck level, but it does not guarantee against future settlement or perfect drainage, and any lift carries a slight risk of new cracking. We set honest expectations before we start.
