Common Hazards When Building Platforms In Wet Ground?

Soil Instability

Building platforms on wet ground requires careful consideration of the underlying soil conditions. In areas with peat or clay soils, the risk of waterlogging is high, and the ground may become unstable when saturated. To mitigate this, construct a raised platform using wooden pilings or helical piers, spaced 6-8 feet apart, to elevate the structure above the water table. This allows for better drainage and reduces the risk of soil collapse.

Slippery Surfaces

Wet surfaces can be extremely slippery, making it difficult to maintain footing. To prevent accidents, apply a non-slip coating or texture to the surface of the platform. A 1:1 mixture of calcium chloride and water can be applied to the surface to create a temporary non-slip coating. Additionally, consider using a slip-resistant material, such as textured steel grating or rubber matting, to provide traction on the platform.

Water Accumulation

Water can accumulate on the platform, causing erosion, damage to materials, and creating a hazardous environment. To prevent water accumulation, ensure proper drainage by installing a French drain or a culvert beneath the platform. The drain should be sloped to direct water away from the platform, and a minimum of 6-8 inches of freeboard (height above the water level) should be maintained to prevent water from seeping under the platform.
