What happens when your volume builder does things on the cheap and doesn’t install engineered and certified screw piles to stabilize your home????
What might sound like a great price for a new home, could end up having disastrous consequences. When a volume builder cuts corners and doesn’t install engineered and certified screw piles, it could end up costing you thousands in underpinning as well as repairs to damage caused or in extreme cases, the cost of a knockdown and rebuild of your home.
Here’s what usually happens:
Structural Movement and Settlement
Homes built without screw piles lack proper support on the diverse and shifting soils found beneath the surface. Screw piles are specifically designed to transfer structural loads to deeper, more reliable soil strata. Without this stabilization, the following problems can develop:
- The house may sink unevenly as the soil compresses or shifts.
- You might notice cracked walls, uneven floors, doors and windows sticking, or gaps appearing between walls and ceilings.
- In clay-rich or reactive soils, seasonal moisture changes can cause even more movement.
Loss of Structural Integrity
In the absence of screw piles to ensure adequate stabilization, the structural integrity becomes compromised, resulting in:
- Foundations may crack under stress.
- Slabs can heave, tilt, or break apart.
- Load-bearing walls may become compromised, risking long-term damage that’s expensive to repair.
Moisture and Drainage Problems
Poorly stabilized homes often develop issues with water pooling around or under the foundation, which accelerates soil movement and structural decay.
Financial and Legal Consequences
- Repair costs – retrofitting certified screw piles, underpinning, or full foundation replacement
- Insurance issues – insurers may not cover damage caused by poor workmanship or uncertified foundations.
- Legal recourse – legal costs for pursuing claims with the builder or authorities.
👉 Simply put, avoiding engineered and certified screw piles is a shortcut that leaves the homeowner carrying the risk and cost. A house might seem stable at first glance, but hidden problems can grow into severe — and very expensive — repairs over time
WARNING SIGNS
Below are some warning signs that can suggest your home may not have been properly stabilized with engineered and certified screw piles:
Early Visible Signs (Months to a Few Years After Build)
- Cracks in walls or ceilings
- Uneven or sloping floors
- Difficulty opening and/or closing doors and windows
- Skirting boards separating
Medium-Term Signs
- Exterior brickwork cracking
- Slab movement
- Ponding water near the house
- Decks, patios, or driveways pulling away
Severe / Long-Term Signs
- Large structural cracks
- Roof misalignment
- Uneven gaps under doors
- Noticeable tilting of the house
Other signs of an unstable build:
- No engineering certification or piling reports provided at handover.
- Neighbours don’t have issues and you both have the same soil conditions
- Builder isreluctant to share engineering drawings or compliance certificates.
MORAL OF THE STORY
ALWAYS use engineered and certified screw piles in your build to guarantee stability and long-term structural integrity for your home.
