The Benefits of Applying Spray Foam Under Concrete
Spray foam can be an incredibly effective way to protect your concrete structure from the elements. This relatively simple process involves spraying a foam-like substance onto an existing concrete surface and allowing it to expand and harden as it dries. This creates a seal that helps to keep moisture out which can save you money in the long run by providing insulation for your structure and preventing potential damage from water seepage.
How Does Spray Foam Insulation Work?
Spray foam insulation works by expanding when exposed to air forming a thick layer of insulation that prevents heat transfer. This means that when applied beneath concrete spray foam can help keep the surface of the concrete cool during the summer months and warm during the winter months. It also helps reduce condensation on the surface of the concrete which can cause damage over time if left unchecked. Additionally, due to its low resistance to water penetration, it is particularly useful in areas prone to flooding or other water events.
Spray Foam Improves Durability
Spray foam concrete can be used in many different types of construction projects but it is particularly useful for foundations since it provides an extra layer of protection against weathering and damage from shifting soils. The sprayed-on foam seals cracks and gaps that can form over time due to extreme temperatures or pressure from the ground. This improves the overall strength and stability of the foundation ensuring that it will last for years to come with minimal maintenance required.
Better Sealing Against Air and Moisture Infiltration
Spray foam insulation also helps create a more secure seal against air and moisture infiltration. This is especially important in areas where soil movement is likely to occur due to temperature changes or other factors. The sprayed-in foam forms an airtight seal that prevents water from seeping through small cracks in the concrete wall or floor, which can lead to mould growth over time. Additionally, this seal also helps keep conditioned air inside your home rather than letting it escape through gaps in the foundation walls.
Lastly, using spray foam insulation under concrete boosts energy efficiency by providing additional insulation against heat transfer. This helps keep your home cooler in the summer months and warmer during the winter months by preventing heated or cooled air from leaking out through cracks in the foundation walls. Furthermore, spray foam acts as a sound barrier between your home's interior rooms and exterior noise sources like traffic or neighbours’ conversations, a bonus if you live near a busy street or a loud neighbourhood.
