Footings & Ground Slabs

Footings & Ground Slabs – Residential Foundation Design in Brisbane

Footings and ground slabs are the most critical structural elements, as they support the entire building. Inadequate design may lead to excessive movement or structural failure. SNG Engineers designs all footings and slabs in accordance with current Australian Standards, all site-specific factors that may influence structural performance are considered.

At SNG Engineers, foundations are designed to be both economical and structurally sound, without compromising on the safety or durability of the structure. Different foundation systems are adopted to suit varying soil conditions, structural forms, and project requirements.

For most residential projects such as detached dwellings, townhouses, and extensions, footings and slabs are generally designed in accordance with Australian Standards AS-2870, based on the site classification report. In certain situations where the code has limitations, professional engineering judgement is applied to develop an appropriate and reliable foundation solution.

Footings & Ground Slab Services in Brisbane

  • Conventional Footings & Slabs

    Traditional reinforced concrete slabs with perimeter and internal thickened beams designed to distribute building loads into the ground. Beam depths are adjusted based on soil reactivity, making this system robust and widely used for residential construction.

  • Waffle Pod Footings & Slabs

    A ribbed slab system formed using polystyrene pods with reinforced concrete ribs and edge beams. This system reduces concrete volume, allows faster construction, and is commonly used on flat sites where soil conditions permit.

  • Column Footings

    Isolated reinforced concrete footings designed to support steel or timber columns. Commonly used for raised floors, sloping sites, or flood-affected areas where the structure is elevated above ground level.

  • Bored Pier or Backhoe (Bucket) Pier Footings

    Deep concrete piers used to transfer loads to more stable ground when surface soils have low bearing capacity or high reactivity. Often adopted where additional stiffness or settlement control is required.

  • Pad Footings

    Isolated concrete pads supporting columns or masonry piers. Pad footings distribute concentrated loads and may be connected with ground beams to improve overall foundation performance.

  • Screw Piles

    Steel piles installed by rotating them into the ground, used as an alternative to bored piers in loose or collapsing soils. They offer rapid installation, with durability and corrosion protection considered during design.
