House Raising Methods Explained: Slab vs. Pier & Beam vs. Full Basement

Slab Foundation

A slab foundation is one of the simplest and most cost-effective house raising methods. This technique involves pouring a single layer of concrete directly onto the ground, which serves as the base for the house. It’s particularly suitable for smaller homes and is a common choice for many house raising projects in Brisbane.


  • Cost-effective: One of the least expensive house raising techniques.
  • Quick Installation: Can be completed faster than other methods.
  • Minimal Excavation: Requires less digging compared to full basements.


  • Limited Access: Harder to access utilities underneath the house.
  • Less Versatile: Not suitable for areas with high flood risks.
  • Potential for Cracking: Concrete slabs can crack over time due to soil movement.

Pier & Beam Foundation

The pier and beam foundation is a popular choice for house raising projects that require more stability and flexibility. This method uses a series of concrete or steel piers driven into the ground, supporting beams that hold up the house. This is ideal for areas prone to flooding or soil movement.


  • Better Access: Easier to access plumbing and electrical systems.
  • Flood Resistant: Elevates the house above potential flood levels.
  • Flexibility: Can be adjusted to different soil conditions.


  • Higher Cost: More expensive than slab foundations due to additional materials and labor.
  • Maintenance: Requires regular inspections to ensure stability.

Full Basement

A full basement is the most extensive house raising technique, involving lifting the house to construct a new basement underneath. This method maximizes the available living space and significantly increases the home’s value.


  • Additional Space: Adds a whole new level to the house, perfect for extra rooms or storage.
  • High Return on Investment: Significantly boosts the property value.
  • Enhanced Safety: Provides a safer refuge during severe weather conditions.


  • High Cost: The most expensive house raising method due to extensive excavation and construction.
  • Time-Consuming: Takes longer to complete compared to other techniques.
  • Structural Risks: Requires careful planning to avoid damage to the existing house.

Factors to Consider When Choosing a House Raising Technique

Choosing the right house raising technique involves evaluating several key factors:

  1. Soil Conditions: The type of soil on your property can influence the best raising method. For example, sandy soil may require different support structures compared to clay soil.
  2. Budget: Cost is a significant factor. Slab foundations are cheaper, while full basements are more expensive but offer more benefits.
  3. Flood Risk: In flood-prone areas, elevating the house using pier and beam or full basement techniques can provide better protection.
  4. House Structure: The existing house design and structure can determine which raising method is feasible. Older homes may need more careful handling.
  5. Local Regulations: Compliance with local building codes and obtaining necessary permits are crucial for any house raising project.
