Removal house on Stumps

There is one thing that all removal houses have across the board – stumps!

(I can’t recall how many times I have been asked about a house on stilts and I’ve thought “what is that?!”)

Call them what you want, stilts, posts, stumps, piers – they are REALLY important.  This is your contact with the ground and an integral part of keeping your house from falling down.

What kind of stumps are there?

Timber – whether it is treated pine or hardwood (traditional) timber stumps have a completely original look.  Make sure you have a good barrier (ant cap) between the house and the stump, and do a visual inspection at least twice a year for damage. (ie white ants leave a mud trail usually)  Timber stumps also don’t come with an adjustable option, they are that length forever so if you need an adjustable option, start looking at steel posts. (more on that later) Some people choose to do an outer rim of stumps in timber so they have the right ‘period’ look, but use the more practical steel stumps under the body of the house.

Brick or Concrete– many NSW homes are on brick stumps – and truthfully, we haven’t installed a house on brick stumps since I’ve worked here so I don’t know much about them. I have seen many houses on concrete stumps prior to us removing the house. One of the main problems with this form of stumps is that over time, the concrete cracks. A concrete stump can look fine from the outside but have an internal crack acting as a conduit for water, and any dampness attracts ants.

Steel Stumps – our preferred stump at Redhouse. We generally use 75x75x4mm Duragal steel posts. (this means that the stump is 7.5cm square with a 4mm thickness in the wall) The posts are galvanised to help prevent rust. (we also paint the lower section of the stump with bitumen paint for an added barrier). Steel posts can have an adjustable top so that if your house gets ‘out of level’ it is a simple adjustment to correct. Stumps can become uneven due to soil moving (black soil moves when wet), or if the foundations are not into natural ground. One of the great things about steel stumps is that if you are going high-set, a 75×75 stump can be hidden in a normal wall thickness. (this means you won’t see where the stumps are as they are in behind the plaster). Of course, if you are having your house high-set, you will want to space out the stumps underneath so that you get a decent size room. This is done with additional steel beams. The exact dimension of the beams is calculated by the Engineer at the plan stage as these are load bearing. Stumps cannot just be taken away without bearing the weight of the house to another point. For more details on spacing’s please contact the office on 07 3287 5535.

    Concrete stumps have a 10mm diameter threaded rod along the top, which helps secure poured concrete pad footings. This rod makes sure that the stump can be securely attached to the frame of the floor. Concrete stumps have an endless shelf life. The only exception is when they’re in the dampest conditions. In damp conditions, the rod that serves as their reinforcement may rust or bow. This is very specific to Queensland, where it’s important to source a different type of stump for your restumping job.

      Thank you Kira, as we are based in Queensland so we choose a Galvanised stump first over all types.
