Melbourne’s diverse soil types can cause foundation problems in homes. What is the age-old remedy? Underpinning. But here’s where things get spicy: when you decide on underpinning melbourne homes, do you go with traditional concrete or the new-kid-on-the-block, polyurethane? We’ll see who wins this exciting battle! Location map.
Let’s start with the basics.
The traditional concrete underpinning
It has been used for centuries. This method involves excavating portions of the ground beneath an existing foundation, and then pouring concrete at different stages. The concrete will provide additional structural support once it has hardened.
Since decades, concrete underpinning is the preferred choice. The longevity of concrete underpinning in the construction industry is a testament to its durability.
Concrete is ideal for massive loads: Structures that are large and need to be supported by a lot of weight often choose concrete.
The solution is permanent once it has been implemented.
It is time-consuming: You will need to dig and wait for the concrete to harden.
It can also damage your driveway or garden.
Polyurethane Injection Underpinning:
This is an innovative method that involves injecting a polyurethane into the soil. The resin solidifies and expands, which lifts the ground and fills voids.
It is a quick fix that can be applied in a fraction of the time as concrete.
No need for extensive excavation. You’ll be able to enjoy your petunias!
Precision: Resin can be precisely injected to only target the affected area.
Environmentally friendly: Polyurethane is a material that has a low impact on the environment.
It is possible that the technology, which is relatively newer, may not be understood or accepted as well as other methods.
It may not always be suitable: This product isn’t the most appropriate for foundations that need extensive support.
Who’s going to win the showdown between the two underpinnings? It depends on the needs of your house, your budget and your timeline. Each method has its advantages. The traditional concrete foundation has a lot of weight behind it. Polyurethane is a more modern and quick solution.
