Cracks, sunken sections, and separation at the coping joint aren't just cosmetic — they allow water under the deck and into the soil below. We assess why the deck is failing before recommending any repair scope.
A cracked or sunken pool deck isn't just a surface problem. In DFW's expansive clay soil, deck movement is almost always driven by what's happening underground — soil swelling and contracting with moisture changes, sometimes with pooling water from a leaking pool or poor drainage accelerating the cycle.
Repairing the surface without understanding the cause means the repair fails for the same reason — usually faster the second time.
We assess the full deck condition before recommending any scope — looking at the crack pattern, the separation at the coping joint, the drainage situation, and whether there's an underlying pool leak or plumbing failure contributing to soil instability beneath the deck. The repair scope is based on what we confirm, not what we assume.
Most concrete deck repairs we perform that hold long-term are preceded by a proper diagnosis. Most that come back are not. With over 20,000 repairs completed across DFW, we've seen every type of deck failure — and more importantly, what causes them to come back.
Schedule a Service CallDeck failures range from surface cracks that need sealing to sunken sections requiring lifting to coping joints that need full replacement. The right scope depends entirely on the condition of the slab and what's driving the movement — which we confirm before recommending any work.
Cracks in the deck surface allow water to penetrate the slab and reach the soil below. We clean, prepare, and fill cracks with appropriate repair material — sealing the surface against further water intrusion. The repair method depends on the crack type, width, and whether the slab is actively moving.
When sections of deck have sunk due to soil movement or void formation underneath, the surface can be lifted using pressure grouting or mudjacking techniques — filling the void and restoring the deck to level without full demolition. This is appropriate when the underlying slab is structurally sound and not continuing to shift.
The expansion joint between the pool coping and the deck is the most critical seal on the entire deck. When this joint opens — which it does frequently in DFW due to soil movement — water enters directly behind the bond beam. We remove the failed joint material and replace it with properly tooled sealant that accommodates movement.
Every deck repair starts with understanding why the deck is moving.
We inspect the full deck surface — crack pattern, joint condition, drainage, and any signs of underlying soil movement or pool leaks contributing to the problem. We confirm this through physical inspection — not assumptions.
If there's any indication that a pool leak is saturating the soil beneath the deck, we run a leak detection before any deck repair begins. Repairing concrete over an active leak is money wasted — and a repair that will fail again.
You receive a clear written estimate before any work begins — scope, method, and timeline all in writing. Repair vs. replacement is determined by the slab condition, not the surface appearance.
We perform the appropriate repair — crack sealing, section lifting, or coping joint replacement — using materials suited for pool deck exposure and DFW's soil conditions. Repairs are completed with minimal disruption to the surrounding pool area.
Every deck repair is backed in writing. 3-year warranty on seal-related repairs. Transferable to new homeowners at no additional cost.
If something isn't right, we come back. That's not a policy — it's how we operate.
Every repair is backed in writing, with clear coverage and real accountability. Warranties are transferable to new homeowners at no additional cost — a documented asset at closing.
Not necessarily — but it should be evaluated together. A cracked deck can allow water to get under the slab and contribute to soil instability regardless of whether the pool itself is leaking. If there's also unexplained water loss from the pool, a leak detection should be part of the same visit. We confirm this through physical inspection — not assumptions.
Yes, in many cases. If the slab is structurally sound and not actively moving, crack repair and joint sealing can restore the deck surface and stop further water intrusion. If the slab is continuing to move — which we assess during the inspection — repair alone won't hold. We tell you which situation you're in before recommending any scope.
Primarily the clay soil. DFW sits on some of the most expansive clay in the country — it swells significantly when wet and contracts when dry. That cycle puts constant stress on the concrete above it. Temperature extremes accelerate the movement. An active pool leak beneath the deck compounds it significantly.
The coping joint is an intentional expansion joint between the pool shell and the surrounding deck — it's designed to allow independent movement between the two. The problem is that the sealant in this joint deteriorates over time and needs to be replaced. When it fails, water enters directly behind the bond beam — which is why it's the most important joint on the deck.
Most crack repairs and joint resealings are completed in a single day. Section lifting typically takes one to two days depending on the area involved. We give you a clear timeline in the written estimate before any work begins.
Tell us what you're seeing, and we'll assess the full deck condition — cracks, joints, drainage, and underlying causes — before recommending the right repair.
