Types of Polyurethane Used in Foundation RepairPolyurethane is a versatile material that can be used for a variety of foundation repair applications. There are two main types of polyurethane that can be used in foundation repair: rigid foam and flexible foam. Both types of foam have their own advantages and disadvantages, so it's important to understand the differences in order to choose the right product for your needs. Rigid foam is a type of polyurethane that is applied in a liquid form.
Once applied, it expands and hardens, forming a strong and durable seal. It is often used to fill cracks and gaps in concrete foundations, as well as to waterproof foundation walls. One of the main advantages of rigid foam is that it is very strong and resistant to water and other elements. However, it can also be difficult to apply and can cause structural damage if not applied correctly. Flexible foam is another type of polyurethane that is typically used for foundation repair.
This type of foam is applied in a liquid form, but unlike rigid foam, it expands and hardens without forming a solid seal. This allows it to move with the foundation and provide additional support. Flexible foam is often used to fill larger cracks and gaps in foundations, as well as to seal off areas where water could enter. The main advantage of this type of foam is its flexibility, which makes it less likely to cause structural damage.
However, it is less resistant to water than rigid foam. When choosing a type of polyurethane for foundation repair, it's important to consider the specific needs of your project. Rigid foam may be the better choice if you need a strong and durable seal, while flexible foam may be the better choice if you need more flexibility or if you're working on larger cracks or gaps. Regardless of which type you choose, make sure to follow the manufacturer's instructions for proper application. Polyurethane is an excellent choice for foundation repair due to its strength, durability and water resistance. It is important to choose the right product for your needs, install it properly and take care of it to maintain its integrity.
