Foundation piering in Sydney plays a major role in ensuring the structural stability of a building. In recent years more and more buildings are built on unstable ground soil. Soils are generally hydro-compactable which easily e gets pushed making it unstable. Due to the several homeowners have to keep repairing foundation issues. They approach piering engineers to provide permanent solutions that help solve them.
- Learn more about the type of soil that the house is to be built on:
Piering engineers in Sydney first focus on the type of soil and structural problems that come with it. It is important to prevent the foundation from being established on unstable soil and instead establishing it on bedrock and other stable soils. This is known as piering. The most common solutions available for establishing strong foundations through piering includes helical piers and push piers.
- Push piering:
In push piering, long steel shaft are used. It is established deep into the soil or bedrock with the help of hydraulics. It passes through several layers of the surface soil and embeds itself deep into the bedrock and other stable strata. The piering engineers know that they have hit stable bedrock by calculating the hydraulic pressure that is applied to enable the peers to reach the specific depth. The weight of the foundation is then taken off the unstable soil and established onto the bedrock pie with the help of pier brackets.
- Helical piering:
Helical piering is one of the top choices in the laying of home foundations. It is embedded deep into the ground with the help of hydraulics. Upon reaching the specified depth deep in the ground, it is wound deep underground like a giant screw. It is capable of withstanding high resistance power and holding up the entire weight of the building during the establishment of the foundation. Once the specific depth is reached, steel brackets are used to shift the weight of the building onto the piers.
When you need Piering?
Piering in Sydney is necessary for tackling several foundation issues which include the following:
- Foundation is shifting or moving vertically.
- Foundation surface area is sinking and not on a stable level with the rest of your home.
- The foundation is built on loose and unstable sand, hydro compactable, subsiding, and expansive soil types.
- Different areas of your home are not in level with the rest.
How piering is done?
Step 1: The landscaping and soil around the specific site are dug out and set aside.
Step 2: Soil is dug out till the footing of the foundation can be seen.
Step 3: Strong, heavy and rigid steel pier anchoring brackets are fixed into the footing of the home.
Step 4: Hydraulic machines are used to drill the steel piers deep into the bedrock or soil strata.
Step 5: The building weight is shifted on to the bedrock piers.
Step 6: Upon complete inspection and approval by the engineer, the dugout soil is replaced around the home foundation. The landscaping is also set up and restored.
