Client Location: Glen Cove, NY
Service Type: Mudjacking Concrete Raising
Problem
At a residential property in Glen Cove, NY, the concrete slabs surrounding a pool were showing signs of significant sinking and instability. The affected areas included approximately 15 feet by 6 feet on the west side and 40 feet by 4 feet on the north side of the pool.
Over time, water exposure had created large voids in the soil beneath the slabs. This erosion of the subsoil led to uneven surfaces and visible depressions. These sunken slabs not only presented a tripping hazard for the homeowners but also compromised the structural integrity of the surrounding area, making effective waterproofing nearly impossible.
Analysis
Our team at Zavza Seal conducted a thorough assessment and considered two primary concrete raising methods: polyjacking (foam injection) and mudjacking (slurry injection).
While polyjacking is often preferred for its speed and precision, the open space near the wooden fence made it an impractical and costly choice in this case. The foam would disperse too widely and unevenly, reducing efficiency. Therefore, mudjacking was selected as the more controlled and cost-effective solution.
Solution
Zavza Seal implemented a customized mudjacking concrete raising process designed to restore the poolside slabs safely and efficiently:
- Expansion Joint Preparation: We began by cutting the expansion joints of all affected concrete slabs. This allowed each slab to move independently and prevent future cracking during lifting.
- Precision Drilling: Our crew drilled strategically placed holes into the sunken slabs to allow access for the grout injection.
- Stone Slurry Grout Injection: We pumped a high-strength stone slurry mixture under the slabs through the drilled holes. This grout filled all underlying voids and began applying upward pressure.
- Controlled Lifting: As the slurry settled and expanded, it gently lifted the slabs back to their original height. We ensured each section was level and sloped slightly away from the pool foundation to improve drainage.
- Joint Sealing: Finally, we sealed the expansion joints to protect the slabs from water infiltration and to maintain long-term stability.
Outcome
The mudjacking process successfully restored the sunken concrete slabs to a safe, level condition. The risk of water damage, trip hazards, and further structural compromise was eliminated.
This solution not only enhanced the safety of the pool area but also extended the life of the concrete by addressing the root cause of the deterioration.
