Most projects are completed in just a few hours, depending on the size and severity of the issue. You can usually use the surface the same day.
Yes. Both spray foam insulation and polyurethane concrete leveling are often more affordable and less disruptive than tearing out and replacing materials entirely.
Yes! While Spray Foam is more costly upfront, it is far more resistant to outside elements (pests, water, etc.) and has a much better R-value making it a better investment long-term. Consumers report that spray foam insulation can save up to 50% on your energy bills.
Yes, both spray foam insulation and polyurethane concrete leveling are safe when installed by trained professionals. Spray foam is non-toxic once cured and creates a durable, airtight barrier. Polyurethane foam used in concrete leveling is environmentally inert, water-resistant, and does not leach harmful chemicals. IOK follows industry best practices to ensure a safe application every time.
Yes, both spray foam insulation and polyurethane foam concrete leveling are designed for long-term performance. Spray foam provides a durable, airtight seal that can last the lifetime of your structure without sagging or settling. Polyurethane foam used in concrete leveling is stable, resistant to moisture, and formulated to maintain its strength and support for many years. When applied properly, these solutions offer reliable, lasting results.
Costs vary based on the size and complexity of the project. However, both services are typically more cost-effective than full replacements or ongoing energy loss. IOK offers free estimates so you can get an accurate quote before committing. Generally, the cost of spray foam insulation ranges from $1.20-$2.50/ board foot.
Spray Polyurethane Foam (SPF) is up to 40% more efficient than other insulation techniques. In addition to being much more efficient than fiberglass and cellulose, it is also safer to use as well as more environmentally friendly. The numerous benefits of choosing SPF insulation over other types of insulation include:
-Higher R-values
-Increased energy savings
-Added structural strength
-Provides a seamless air barrier
-Stops moisture transmission
-Resists mold & mildew growth
-Improves indoor air quality
-Effective sound insulation
-Low long-term maintenance costs
New construction, remodeling, walls, ceilings, basements, attics, crawl spaces, garages, pole barns, foundations, roofs, and anything else that needs insulating!
The U.S. Department of Energy estimates that up to 40% of the cost of heating and cooling the average home is wasted on uncontrolled air leakage. The air that you are paying to heat/cool is leaving your home through gaps, cracks, and holes. Air can go straight through glass fiber and cellulose, but it can't go through SPF insulation, which has been engineered to combine superior insulation performance and complete air leakage control. Closed-cell SPF insulation virtually eliminate uncontrolled air leakage. In addition to its energy-saving properties, SPF insulation can help prevent these undesirable situations:
-Indoor environment that is too humid or too dry
-Hard to heat rooms
-Cold drafts
-Mold & mildew growth
-Ice buildup and water damage due to heat loss
Yes, closed-cell spray foam is highly water-resistant making it an ideal choice for roofing or basements. In fact, It is the only insulation that FEMA rates as class 5, their highest flood resistance level.
Closed-Cell spray foam has a far great R-value per inch than fiberglass or even cellulose insulation. It is estimated that spray foam can last anywhere from 80-100 years making it an investment that will last a lifetime.
When choosing your spray foam insulation, there are really two choices; Open Cell or Closed Cell.Closed-cell doesn’t expand as much, making it dense with a high R-Value, completely water-resistant, and even adding structural strength to your build.This is the ideal choice for most applications, however, open-cell spray foam has other qualities that make it unique; it is the better choice for soundproofing as well as better for sealing small cracks/crevices because of its greater expansion upon installation.
Yes! While Spray Foam is more costly upfront, it is far more resistant to outside elements (pests,water, etc) and has a much better R-value making it a better investment long-term.Consumers report that spray foam insulation can save up to 50% on your energy bills.
Yes, you certainly could install your own spray foam insulation but it comes with some disclaimers. While the price for most DIY kits is about $1000, you should know that kits are 20-30% lower yield than advertised. That puts you at about $2.15/board foot, so it might actually be cheaper to have a professional install it. Also, keep in mind that you need to cover anything that you don’t want foam on and that you need to follow manufactures instructions precisely to avoid shrinkage, smells or unwanted mess.
Spray foam insulation can last for decades, often the life of the structure. Unlike traditional materials, it doesn’t sag, compress, or degrade over time when properly installed.
Yes, once cured, spray foam is inert and safe. During installation, occupants and pets should stay out of the area until the foam has fully set and any ventilation requirements are met, typically within 24 hours.
Absolutely. By sealing air leaks and improving thermal resistance, spray foam insulation can significantly reduce heating and cooling costs.
Small holes are drilled into the sunken concrete, and polyurethane foam is injected beneath the slab. As the foam expands, it fills voids and gently lifts the concrete back to its original position.
Most projects are completed in just a few hours, depending on the size and severity of the issue. You can usually use the surface the same day.
Yes. Once cured, the foam is incredibly strong and stable, capable of supporting heavy loads including vehicles and machinery.
In most cases, the surface is ready for normal use within 15–30 minutes after the foam has cured.
No. Polyurethane foam is water-resistant and doesn’t wash away like traditional mudjacking materials. It’s designed to last for years and maintain stability beneath the slab.
Common causes include soil erosion, poor compaction during construction, moisture changes, and natural ground settling over time. These factors can create voids under the slab, causing it to sink or crack.
Yes. Both spray foam insulation and polyurethane concrete leveling are often more affordable and less disruptive than tearing out and replacing materials entirely.
