Cracked Pool Deck

A swimming pool is a perfect way to relax, unwind, and enjoy quality time with loved ones. But this area can quickly become dangerous if the surrounding concrete is damaged.

Cracked pool decks not only diminish the visual appeal of your home but also pose significant safety hazards. Bay Area Underpinning understands the urgency of resolving such matters.

With a wealth of experience in concrete lifting, we specialize in providing sustainable solutions to safeguard your home against the detrimental effects of cracked concrete, ensuring the longevity and safety of your property.

This page explains the reasons behind a cracked concrete pool deck and how Bay Area Underpinning uses advanced methods like SettleStop™ PolyRenewal™ to restore the integrity of your pool deck with precision and reliability.

What Is a Cracked Pool Deck?

A cracked pool deck refers to fissures or splits in the concrete slabs surrounding an in-ground swimming pool.

These fractures can range from minor, superficial cracks to severe breaks that compromise the stability of the pool deck. Such cracks tarnish the aesthetic value of your pool area and are hazardous, leading to tripping accidents and injuries.

Cracked pool decks allow water intrusion, leading to further deterioration of the concrete, mold growth, structural instability, and diminished appearance.

A cracked pool deck may also be accompanied by other problem signs, including:

These problems worsen with time, creating more significant hazards and expensive repairs. It’s crucial to contact a local concrete lifting professional like Bay Area Underpinning when you notice these issues.

What Causes a Cracked Pool Deck?

Cracked pool decks typically result from a variety of factors, including:

  • Settling Soil: The ground underneath the pool deck can settle unevenly over time, causing the concrete to sink and crack. This may happen if the soil was not properly compacted before the concrete pool deck was poured.
  • Soil Erosion: Water carrying chemicals, flowing from the pool deck, can erode the soil beneath and create voids, causing cracking and sinking.
  • Tree Roots: Aggressive tree root systems growing under the deck can displace the underlying soil and push up sections of concrete.
  • Weather: Over saturation of the soil from heavy rain or flooding can cause it to compact or wash away, disturbing the support for the concrete deck. Conversely, drought conditions can also cause soil to shrink and pull away from the pool deck, creating voids and causing the concrete to sink or crack.
  • Earthquakes: In California, earthquakes are a common occurrence and can have a significant impact on the stability of your pool deck. The shifting and shaking of the ground can cause the concrete to crack and move, leading to misaligned slabs, tripping hazards, and potential damage to the pool itself.
  • Original Installation Issues: Mistakes when pouring the concrete and issues with the curing process can lead to cracks and structural defects.

Sometimes, a combination of these factors results in the cracking and sinking of pool decks.

The same soil stability issues that damage pool decks can also impact the home’s foundation, requiring immediate attention and resolution by professionals to prevent the escalation of damage.

Can You Fix a Cracked Pool Deck?

Absolutely! Fixing a cracked pool deck is crucial.

However, the right solution involves more than just patching cracks or applying an overlay. DIY repairs and traditional methods like mudjacking become time-consuming, expensive, and don’t address the root of the problem.

A comprehensive solution addressing the entire home is imperative for lasting results. A holistic approach ensures that the underlying causes are tackled, preventing future occurrences and maintaining the structural integrity of your property.

At Bay Area Underpinning, we use specialized techniques to stabilize, and lift cracked and settled sections of pool decks. Our exclusive PolyRenewal™ polyurethane foam injection process gently raises sunken concrete and provides lasting support.

How to Fix a Cracked Pool Deck

Bay Area Underpinning’s expert team follows these steps to thoroughly repair your pool deck:

  • Inspection: Our team thoroughly examines your pool deck to identify what factors are causing the concrete damage. We determine the ideal lifting points and repair plan.
  • Drill Holes: Small, penny-sized openings are drilled into the affected areas of the sunken concrete.
  • Place Injection Ports: Custom injection ports are inserted into each hole to allow access underneath the slab.
  • Mix Foam: We blend the two proprietary components of our high-density polyurethane foam.
  • Inject Foam: The foam is pumped beneath the concrete through the injection ports.
  • Foam Expansion and Slab Lifting: The foam rapidly expands underground, filling voids, and hardening within 15 minutes. This lifts the concrete slab gently back into place as the foam cures.
  • Remove Ports: We remove the injection ports and patch the access holes.
  • Seal Cracks: All cracks and joints are sealed to prevent future water intrusion.
  • Ongoing Care: Periodic maintenance helps maximize the durability of your repaired pool deck.

Bay Area Underpinning’s process addresses the symptoms and root causes of pool deck damage for long-lasting repairs. Our proprietary products are specifically designed to address your unique needs, offering superior, personalized solutions that outperform conventional remedies available in the market.

Why Address Pool Deck Cracks Now

It is crucial to repair pool deck cracks, unevenness, and other damage as soon as they appear for several reasons:

  • Prevent Further Damage: Existing damage will spread over time without proper repairs. Small cracks allow water penetration that damages the steel rebar inside and expands cracking. However, addressing cracks at their first sign prevents escalation and additional costs.
  • Safety: Cracking and uneven concrete around the pool presents a safety hazard for pool users, but effective repairs eliminate tripping hazards and potential injuries.
  • Avoid Expensive Repairs: The further damage occurs, the more extensive repairs will be. It is less expensive to fix minor issues now than completely replace the pool deck later.
  • Enhance Property Value: Cracks and deterioration negatively impact the appearance of your backyard oasis, but quick repairs maintain aesthetic appeal and structural integrity.

To rectify cracked pool decks fully, trust Bay Area Underpinning and our specialized, proprietary solutions, developed with unrivaled precision and effectiveness, surpassing standard products.
