Ground Screws in Wet or Flood-Prone Areas: What You Need to Know
Installing foundations in wet, marshy, or flood-prone areas can be challenging, but ground screws provide a durable and reliable solution. At GBGS, we specialise in designing and installing ground screw systems that perform in a variety of soil conditions, including waterlogged or flood-prone environments.
This guide explains what you need to know to safely and effectively use ground screws in these challenging conditions.
Why Ground Screws Are Suitable for Wet Areas
Unlike traditional concrete foundations, ground screws are ideal for areas with high water tables or poor drainage:
- Minimal soil disturbance: Ground screws require little excavation, preserving soil integrity.
- Quick installation: Screws can be installed without waiting for curing, which is critical in wet conditions.
- Adjustable and stable: Helical design allows screws to anchor securely, even in soft or saturated soil.
- Durable materials: Galvanised steel screws resist corrosion and maintain structural integrity over time.
These features make ground screws a safe and effective option for gardens, decking, log cabins, solar installations, and other structures built in wet or flood-prone areas.
Key Considerations for Installation
When installing ground screws in wet areas, several factors must be carefully considered:
1. Soil Assessment
Understanding soil composition and water levels is critical. Soft, clay-heavy or silty soils require specific screw types and lengths to ensure stability.
2. Corrosion Protection
GBGS uses high-quality galvanised steel screws with protective coatings, ideal for resisting moisture and extending the life of your foundation.
3. Proper Anchoring Depth
Screws must reach stable subsoil layers to provide a reliable base. Depth and spacing are determined based on load requirements and soil conditions.
4. Drainage Solutions
Proper site preparation, including minor grading or drainage channels, can enhance long-term performance by reducing water pooling around screws.
Common Applications in Wet or Flood-Prone Areas
