Why is the soil a decisive factor in foundation construction?
Beneath every slab on ground and against every retaining wall lies a hidden threat: clay and silt.
Many believe that a low water table is a safeguard against foundation issues. This assumption can lead to costly mistakes.
Clay and silt don’t need a high water table to cause problems. They expand and contract with moisture changes, creating significant pressure on your concrete slab and walls.
The result? Cracking and structural damage that could have been avoided by understanding the different soil types and their behaviour.
Here are three practical steps to mitigate this risk:
1. **Soil Testing**: Always conduct thorough soil analysis before construction. Understand the composition and moisture behaviour of the ground beneath your slab.
2. **Drainage Solutions**: Implement effective drainage strategies to manage surface water. This helps minimise moisture fluctuations in the soil.
3. **Foundation Design**: Consider using an adequate reinforced foundation system that accommodates soil movement.
Investing in these measures upfront can save you from future headaches and ensure your projects stand the test of time.
Stay ahead of the curve. Prioritise soil integrity for lasting foundations.
