Toowoomba Soil Types & How They Affect Construction

Toowoomba Soil Types & How They Affect Construction

There’s this children’s song that goes: “Don’t build your house on the sandy land, don’t build it too near the shore. Well, it might look kind of nice, but you’ll have to build it twice, oh, you’ll have to build your house once more.”

This song may be intended for kids, but it effectively brings to light the importance of soil types in establishing a good foundation for buildings.

Construction companies know this all too well, which is why prior to the actual building process, they meticulously study the building site’s soil (along with other conditions) and determine how its quality can directly impact everything from the process of construction to the stability of the entire structure, to the ease of integrating ground components like plumbing, and so much more.

Speaking of soil types, different areas naturally have different ones; at times, one area can have more than one type of soil. For example, in Toowoomba there are two common soil types — you get black soil and red soil, which are greatly different from each other. Between these Toowoomba soil types, black soil is considered the tricky type to work with – it’s perfect for farming but it’s reactive and tends to have big range of movement when conditions shift from dry to wet. Red soil, on the other hand, is clay soil (M-type soil classification) which is more stable and actually quite ideal for construction.

It’s for these differences that construction companies require accurate results of soil testing first, before they can proceed to other transaction responsibilities. From the results, they determine the challenges that the quality of soil will present, and are able identify the best solutions to work against these challenges. When solutions are established, then they are able to provide their clients a fair estimate of how much the building project will cost.

Now, in working with certain soil types, some require special building methods; and when special building methods are required, naturally, there are changes in the choice and cost of materials to be used for construction. Along with that, adjustments have to be made with the projected schedule for the completion of the project.

For areas in Toowoomba with mostly black soil, a lot of work and money can be expected to go into the creation of a solid foundation; several layers of steel and concrete are required to get to the stronger clay beneath and withstand the natural range of movement that black soil creates. As for brown or red soil areas, the slab or foundation does not really need special reinforcements; therefore, they are cheaper and faster to establish.

So for Toowoomba folks who are thinking of having a house built, it’s important to find a building company that really studies the different variables that affect construction such as soil type and classification. This way, you can effectively protect your investment and gain the security that your house will be a completely safe refuge for you and your family.
