Polyurethane material is injected as a liquid that sets-up as a rigid foam.
This foam will never lose density or shrink. This material is lighter than traditional mud-jacking material, and as a result, puts less stress on the unstable soils beneath your concrete. Unstable soils are the reason that your concrete has settled. Boost Concrete Lifting foams infiltrate the air spaces within the underlying soils and aggregates beneath your concrete, and essentially bind them together so that the foam has a stable surface to lift against. This material is non-erodible and non-decomposable due to its hydrophobic properties.
CONCRETE SLAB LIFTING AND REPAIR IN MANITOBA
How long does polyurethane concrete lifting last?
Polyurethane concrete lifting is a durable and long-lasting solution for concrete leveling and repair. The exact lifespan of the repair will depend on several factors, such as the extent of the damage, the quality of the installation, and the conditions the slab is exposed to after the repair.
In general, polyurethane concrete lifting can last for several years or even decades with proper installation and maintenance. The foam used for the repair is resistant to moisture and chemicals, which helps prevent future settling or sinking.
It's important to note that while polyurethane concrete lifting is a long-lasting solution, it may not be suitable for all types of concrete damage or settling. Consult with a professional concrete lifting contractor to determine the best repair method for your specific situation.
How much does polyurethane concrete lifting cost?
The cost of polyurethane concrete lifting can vary depending on several factors, such as the size of the area to be repaired, the extent of the damage, and the location of the property.
Generally, the cost of polyurethane concrete lifting is lower than other repair methods such as replacing the concrete slab. The cost per square foot can range from $3 to $10, but it's important to note that this is only an estimate and the final cost will depend on the specific factors mentioned above.
It's recommended to get a quote from a professional concrete lifting contractor to get an accurate cost estimate for your specific repair needs. They can evaluate the damage and provide a detailed estimate that takes into account the specific factors affecting the repair cost.
Does lifting concrete with foam work?
Yes, lifting concrete with foam injection, also known as polyurethane concrete lifting, is a highly effective and widely used method for concrete repair and leveling.
The process involves drilling small holes in the affected concrete slab and injecting a polyurethane foam mixture into the voids beneath the slab. The foam expands, filling the voids and lifting the slab back into its original position. Once the foam has cured, the holes are filled, and the surface of the slab is restored.
Polyurethane foam injection is preferred over traditional methods like mudjacking because it is less invasive and requires fewer and smaller holes. The foam is also more lightweight, meaning it puts less stress on the soil below the slab. Additionally, the foam is resistant to moisture and other environmental factors that can cause the slab to sink or settle again in the future.
Overall, polyurethane foam injection is a highly effective and efficient method for lifting concrete and restoring the appearance and functionality of damaged or uneven concrete slabs.
Will expanding foam lift concrete?
Yes, expanding foam can be used to lift concrete through a process called polyurethane foam injection, also known as foam lifting. In this process, a polyurethane foam is injected into voids beneath the concrete slab, causing the foam to expand and lift the slab back into place.
The expanding foam used in this process is specifically designed for lifting and leveling concrete. It is lightweight, yet strong enough to support the weight of the slab. Additionally, the foam is waterproof and resistant to other environmental factors that can cause the slab to settle or sink again.
Foam lifting is becoming a more popular method of concrete lifting and leveling due to its numerous advantages over traditional methods like mudjacking, such as the ability to use smaller injection holes and achieve more precise lifting.
It's important to note that while expanding foam can be effective in lifting concrete, it is important to have the process performed by a professional concrete lifting contractor who has the proper equipment and expertise to ensure the job is done correctly and safely.
What is the best concrete lifting method?
The best concrete lifting method can depend on various factors such as the size of the area to be repaired, the extent of the damage, and the underlying cause of the problem.
Two popular methods of concrete lifting are mudjacking and polyurethane foam injection. Mudjacking, also known as slabjacking, involves drilling holes in the concrete slab and pumping a slurry mixture underneath to lift it. Polyurethane foam injection, on the other hand, involves injecting expanding foam underneath the slab to lift it back into place.
Both methods have their advantages and disadvantages, and the best method for a particular situation will depend on the specific circumstances. For example, polyurethane foam injection is often preferred for smaller repair jobs because it requires fewer and smaller holes and the foam is lightweight and durable. On the other hand, mudjacking may be better suited for larger, heavier slabs because it is more cost-effective and can lift heavier loads.
It's recommended to consult with a professional concrete lifting contractor to evaluate the damage and recommend the best lifting method for your specific needs. They can evaluate the situation and provide an accurate estimate of the cost and time required to complete the repair.
