House Restumping/underpinning

House underpinning.

  Underpinning is the process where a building’s foundation gets strengthened. The following are reasons why someone might really want to underpin their house;

Changing of the structure in terms of its usage.

  1. Movement of the house due to natural causes like floods or earthquake and you need to keep it stable.
  2. Constructing a new house is quite expensive since it requires a lot like buying a new piece of land and all that so underpinning would be the best option so as to cut cost.
  3. Maybe you need to add another story by increasing its depth.
  4. Change in the soil properties holding the foundation into place.

Mostly, underpinning is done by either expanding the foundation in terms of its depth or maybe breath so that it stands on a more strong ground. Using of micro piles and grouting of the jets are methods used in underpinning.

Soil strengthening is also another way of underpinning and it can be done through introducing a gout. Soil is strengthened in places where soils of problem class are found.

Types of underpinning.

Traditional underpinning- also known as the mass concrete underpinning. This is where boxes are dug underneath then concrete is poured in those boxes in a strategic kind of order. A foundation is constructed beneath the already existing one.

Beam and base underpinning- this is a more advanced one. This is where a beam of concrete is built above or below the footing that is in existence.

It is always a good option to underpin your house saves you a lot of work that is involved in building of a new one.


House Restumping.

  Also called reblocking. According to , This is where you replace the stumps on a house that its subfloor uses stumps. Why do you need to restump? This can be due to rotten wooden stumps due to the rising moisture from the soil or settling of the stumps because of movement in soil.

If restumping of a house is not done very well it can cause a lot of accidents since it will not be really safe to stay in such a house. There are signs to show that your house requires restumping when the inside walls of your house have cracks, floors that are not even, cracking of the outside walls and when your windows or door is are not functioning well.

You are advised that if you are restumping, you do it to the whole house because you might think that some parts are in a very good condition when they actually are not hence failure later on.


How do you restump a house?

You have to first evaluate which stumps need replacing. How do you do it? By the use of a level to evaluate how evenly distributed the floors are, and also examining the stumps to see if they deteriorated or moved.

The house is then raised up to where the stump that require replacement is and then the stumps that were originally there are removed to make up for the settling.

It is advised that if need your house restumped you should use the concrete or steel stumps since they do not get rotten. They are expensive but they save you a great deal.
