Screw-piles foundations offer several benefits when building near trees with Tree Preservation Orders (TPOs):
1. Minimal soil disturbance: Screw-piles foundations are installed using a hydraulic torque motor, which creates minimal soil disturbance compared to traditional excavation methods. This means that the root systems of nearby trees are less likely to be damaged during the installation process.
2. Versatility: Screw-piles can be installed in a variety of soil types, including clay, sand, and gravel. This means that they can be used in areas with a high concentration of tree roots, where traditional foundations may not be feasible.
3. Reduced risk of damage to trees: The installation process for screw-piles foundations doesn’t require heavy machinery or large excavation equipment, which reduces the risk of damage to nearby trees with TPOs.
