Polyurethane Foam Can Provide Structural Support

It's essentially a law of nature -- structures tend to weaken over time. Years of exposure to the elements can leave walls lacking support and in need of rehabilitation. In many cases, polyurethane spray foam insulation can provide that needed support.

Spray foam insulation offers many benefits as a structural support option. First, it is lightweight, which makes it a good choice in situations where the weight of concrete would further damage a structure. Second, spray foam insulation is cost-effective. It's easy to apply, so building owners won't be paying for day after day of application fees. The materials themselves are also affordable.

Spray foam insulation is an excellent choice, in particular, for older homes with thin walls. It can be applied between the walls where regular insulation would typically not fit, since a small application nozzle emits enough foam to expand and fill the space. When inserted in these thin walls, the spray foam makes them more resilient while also forming an airtight barrier around the home.

There are several different types of spray foam in the market, each with its own applications. When lending structural support to a wall or other structure, applicators can sometimes create "lifts" of polyurethane foam to prevent structures from sinking further into the ground or leaning. Advanced technology, such as infared cameras, can be used to monitor temperature and tell the applicators how much foam to apply. Often, the foam must be applied slowly, in several layers, allowing each layer to set between applications. Even with this time taken into account, spray foam application is often quick compared to other alternatives such as building concrete supports.
