Reblocking & Restumping in Ivanhoe, Heidelberg and Greensborough

A different kind of northern suburb

Banyule does not look or behave like Coburg or Reservoir. The land climbs and falls, streets wind around ridges, and blocks often slope steeply from front to back. Housing is mixed:

• Ivanhoe and Ivanhoe East have inter-war bungalows, timber villas and some substantial 1930s homes, with heritage overlays over parts of the area.
• Heidelberg and Heidelberg Heights combine older timber housing alongside weatherboard and veneer houses from the 1950s and 60s.
• West Heidelberg includes a large group of former Housing Commission homes, many built for the 1956 Olympic village and surrounding estates.
• Rosanna, Macleod and Watsonia are largely 1950s to 1970s, with weatherboards and brick veneers on sloping blocks.
• Greensborough is a mix of 1960s and 1970s houses, often with split-level designs or high subfloors on the downhill side.

Sloping ground and tall stumps

On a flat block, stumps are short and fairly uniform. On a Banyule slope, the stumps on the high side may be barely visible while those on the low side are more than a metre tall. That changes the job:

• Tall stumps need bracing so the house cannot rack sideways.
• Footings on the low side may need to go deeper, depending on how the ground has been cut or filled.
• Long concrete stumps are heavy, and adjustable steel stumps are often easier to install and brace on tall runs.
• Headroom on the low side is usually good, which helps the crew work underneath.

Soils and drainage

Soils here vary more than on the basalt plains. You may find silty clay, weathered siltstone, older river sediments near the Yarra, or fill brought in when the block was levelled. Some of it is reactive and some is not.

Drainage is often the bigger issue. Water running down a slope collects under houses on the low side, keeping stumps and soil wet. Downpipes that discharge under the house, blocked agricultural drains and paving that sheds water toward the house all add to it. We check drainage as part of every inspection, because restumping without fixing the water problem can lead to the same trouble again.

Creeks and parklands

The Darebin Creek runs along the western edge of Banyule, and the Plenty River and Yarra River shape the eastern side. Houses close to creek reserves, or at the bottom of a long slope, often see more movement. Large established trees in Ivanhoe, Rosanna and Macleod also draw moisture out of clay soils in summer.

Heritage overlays in Banyule

Parts of Ivanhoe, Heidelberg and Eaglemont are covered by heritage overlays. Restumping is generally treated as repair and maintenance, but if the work changes how the house looks from the street — the height of the front floor, the base cladding or the verandah — a planning permit may be needed. We check before lodging the building permit.

Common problems here

• Floors dropping toward the low side of the block where the ground stays damp.
• Tall stumps leaning or racked, especially where bracing was never installed.
• Split-level houses where the levels have moved relative to each other.
• Brick veneer cracking where one corner sits on fill and the rest on natural ground.
• Former Housing Commission homes in West Heidelberg needing a full restump.

Restumping and underpinning together

Many houses in Rosanna, Macleod and Greensborough are brick veneer with timber floors inside. On sloping sites, the brick outer walls may have moved differently from the internal stumps. We assess both and give you a single scope that covers restumping inside and underpinning outside if needed, so everything finishes level.

How we tackle Banyule jobs

Every job opens with a free look underneath. On sloping blocks we pay particular attention to drainage, stump height and bracing, and to whether part of the house is on fill. Then we recommend a stump type and scope of work. On tall runs, we often recommend adjustable galvanised steel for its lighter weight and easy fine-tuning.

Book an inspection

If you live in Ivanhoe, Heidelberg, Rosanna, Macleod, Watsonia or Greensborough and your floors are moving, call us. We will look under the house, check the drainage and explain what needs doing.
