Restumping, Underpinning, Relevelling or Ground Injection
What is restumping or reblocking
Restumping and reblocking are undertaken when building sub-floor supports (ie: the existing timber stumps or brick piers) are no longer adequate or the footings supporting the stumps or brick piers are inadequate.
What is underpinning?
Underpinning is undertaken when footings are inadequate for the loading, site and environmental conditions. Underpinning provides additional support or stability to existing footings or slabs.
What is relevelling or packing?
Relevelling or packing of sub-floors is undertaken to reduce the variation in floor surface level, when the sub-floor supports and framing are adequate.
Do I restump, underpin, reblock, relevel, pack, ground inject, rebuild, manage or do nothing?
We can provide advice on the best course of action. Often addressing other building, site and environmental factors alleviates or helps manage the problems encountered without the need for expensive construction works. Our investigations identify the contributing factors to the problems encountered so you can make an informed decision.
Do brickwork or wall cracks always mean you need to underpin or restump?
No. In many instances underpinning for brickwork cracking or restumping for wall cracking is not required.
Do bouncy or creaky timber floors always indicate you need to restump?
No. There can be many causes and not all require restumping.
Should you have a soil test before you restump or underpin?
Yes – we can assist with this. A soil test also helps identify the source of any problems and the best course of action.
Do you need a Building Permit to restump, underpin or rebuild?
Yes – we can prepare soil reports, designs, drawings and certification necessary for the Building Permit Application.
Can floors always be made completely level and will they remain level?
No. Some variations will always exist. Repairs to existing buildings are often a compromise between cost, benefit, owner’s tolerances, constructability, ongoing risk and performance.
Will a repaired building perform like a new building.
No. Repairs to existing buildings are often a compromise between cost, benefit, owner’s tolerances, constructability, ongoing risk and performance. On-going maintenance, further movement and damage are all possible with a repaired building. We can provide advice on the most suitable repairs to balance your budget, outcomes and performance expectations.
Should you have an expert assess your building before you renovate or alter?
Yes. Its far better to ensure the building foundations and supports are adequate before embarking on repairs / improvements to the rest of the building. If the foundations and supports aren’t adequate, the repairs and improvements could be wasted effort.
