Basement Construction

A basement makes a significant difference in enhancing your home's value and functionality. However, there is a distinction between basement construction and basement retrofitting. Here at Techniblock Pty Ltd, we specialise in basement retrofits (Techniblock handles the underpinning and excavation ready for your chosen builder to handle the balance of the fitout), but we understand the importance of expanding on the differences between the two processes. Helping you to understand why we offer basement retrofits but not basement construction to homeowners throughout Melbourne.

What Basement Construction Involves

• Excavation: The process begins with Underpinning and digging out the soil to create space for the new basement. This requires heavy machinery and expertise to ensure the integrity of the surrounding structures which is Techniblock’ speciality.
• Foundation work: After the excavation, a strong foundation is laid, which includes footings, walls, and slabs, to provide support for the basement and the house above.
• Waterproofing: A crucial step to prevent water infiltration, waterproofing involves applying a protective barrier to the foundation walls and installing proper drainage systems , which can be undertaken after we construct your retention system and handle the excavation.
• Structural work: This includes the installation of support beams and columns, ensuring the stability and safety of the basement, this is works carried out by your builder.
• Finishing work: Once the structure is in place, the basement is finished with flooring, insulation, and other necessary amenities by your builder.

What a Basement Retrofit Involves

• Structural assessment: An evaluation of the existing structure is conducted to determine its suitability for a basement retrofit, and to identify any necessary reinforcement work we can liaise with your Engineer to ensure the correct methodology is adopted.
• Underpinning: Strengthening the existing foundation, underpinning involves digging beneath the foundation and adding support, creating a stable base for the new basement and doubles as a retention system to hold back the surrounding soil surcharge loads.
• Excavation and soil removal: Unlike basement construction, excavation in a retrofit occurs from inside the existing structure, requiring specialised techniques to minimise disruption to the property.
• Waterproofing and drainage: As with basement construction, waterproofing is essential. However, a retrofit may require different materials and methods due to the constraints of working within an existing structure and your Engineer will advise on the most suitable method.
• Integration: Finally, the retrofitted basement is seamlessly integrated with the existing home, ensuring the final product is both functional and aesthetically pleasing.
