We discuss the process of concrete lifting and leveling, emphasizing the use of polyurethane foam systems for raising, leveling, void filling, and stabilizing concrete slabs. These foam systems are specifically designed for application beneath poured, slab-on-grade concrete slabs, offering a durable and efficient solution for addressing uneven concrete surfaces. We are highlight the importance of identifying whether the concrete is a structural pour, as this can impact the method of repair required. Structural pours, such as those with helical piles, may need specialized inspection and lifting techniques by foundation specialists.Furthermore, the sources mention limitations to what can be restored using foam jacking or mudjacking techniques. For instance, precast or hollow cast steps and staircases, broken concrete with little-to-no rebar reinforcement, and patio stones or landscaping bricks may not be suitable for lifting using these methods. The articles also compare foam jacking to mudjacking, noting that foam jacking is a non-invasive, long-lasting alternative that addresses the underlying causes of sunken concrete more effectively.
what is slab jacking and how is it done in calgary
Slab jacking, also known as concrete lifting, is a technique used to raise and level sunken or uneven concrete slabs. In Calgary, slab jacking is typically done using polyurethane foam injection or mudjacking methods. Here is how slab jacking is done in Calgary based on the information from the provided sources:
Polyurethane Foam Injection: This method involves injecting high-density polyurethane foam beneath the sunken concrete slab. The foam expands, fills voids, and lifts the concrete back to its original position. Polyurethane foam is preferred for its durability, efficiency, and long-lasting results compared to traditional mudjacking techniques.
Mudjacking: Mudjacking, also known as slab jacking, is another technique used in Calgary for concrete leveling. This method involves pumping a mixture of sand-based grout under the sunken concrete slab to lift it to a level position. However, mudjacking has some drawbacks, such as being messy, disruptive, and not addressing the underlying causes of sunken concrete as effectively as polyurethane foam injection.
Process: The process of slab jacking Calgary typically starts with a professional assessment of the concrete slab. Measurements and photos are taken to evaluate the extent of the sinking or unevenness. After the assessment, a quote is provided to the property owner. Once the quote is accepted, the concrete lifting process begins, either using polyurethane foam injection or mudjacking techniques to raise and level the sunken concrete slab.
slab jacking Calgary involves using polyurethane foam injection or mudjacking methods to lift and level sunken concrete slabs. These techniques aim to restore the structural integrity of the concrete, eliminate trip hazards, and improve the aesthetics of residential and commercial properties.
In summary, the articles provide insights into the concrete lifting and leveling industry in Calgary, highlighting the use of polyurethane foam systems, the importance of structural assessment, and the limitations of certain concrete restoration methods.
