Slab jacking, alternatively known as mud jacking, is a cost-effective, efficient, and practical solution that addresses a common problem homeowners often encounter - sagging and settling foundation. Responsible homeowners must understand this technique to maintain the structural soundness of their homes. This blog post aims to throw light on the mystery shrouding slab jacking, its importance, and how it functions.
Slab jacking, colloquially known as mud jacking, finds its roots in the construction industry and has proven its worth for decades. The name might suggest a murky procedure, but the principle underlying slab jacking is simple and brilliant. It involves raising concrete slabs by pumping a mixture of water, dirt, and cement, aka "mud," or a polyurethane compound beneath them. This mixture or compound fills empty spaces and voids that cause the foundation to sag or settle, resulting in the lifting and stabilizing of the slab to its original position.
Now, let's delve into why a homeowner needs to understand slab jacking. Homes settling over time is a common phenomenon, especially for homes constructed on expansive clay, improperly compacted soil, or having inadequate drainage system. Over time, these factors can contribute towards void spaces beneath the slab, leading it to crack, sink or settle unevenly. This not only impacts the aesthetic appeal of the property but poses safety risks and potentially decreases the property value. This is where slab jacking steps in as an effective solution to address these issues.
Comparatively, slab jacking is a cost-friendly alternative to slab replacement. The average cost can be less than half the price of complete slab replacement, depending on the extent of the problem. Furthermore, slab jacking is non-invasive, causing minimal disruption to your property. In contrast, a full slab replacement involves demolishing the settled slab, preparing the foundation, pouring new concrete, and letting it cure, which can be time-consuming, disruptive, and messy.
The procedure of slab jacking, in reality, is rather straightforward. Small holes (typically 1 to 1.5 inches in diameter) are drilled into the sunken slab. Then, the "mud" or polyurethane mixture is pumped under the slab through these holes. As the voids fill up, the slab is raised and leveled. The material under the slab hardens and provides a stable base, reducing the probability of further settling. Once the process is completed, the drilled holes are patched up, and the job site is cleaned, leaving behind a well-maintained and safe home slab.
From a sustainability point of view, slab jacking is an eco-friendlier option compared to slab replacement. The latter results in significant construction waste, while mud jacking makes use of the existing slab, significantly reducing the waste.
In terms of longevity, the durability of a slab jacked foundation depends on factors like the quality of workmanship, the materials used, and ongoing maintenance. However, a professionally done job should last for many years, giving homeowners peace of mind about their property's stability.
In conclusion, slab jacking or mud jacking is a practical, cost-effective, and reliable method to rectify foundation settling issues. Offering homeowners a means to reclaim their settled slabs, it's a technique that marries simplicity with effectiveness. As it cements its position in the construction domain, slab jacking continues to help homeowners preserve the structural integrity of their beloved homes while saving time, money, and the environment.
