Practical Notes
Fence posts are constantly in contact with soil and moisture; it is critical to ensure preservative treatment strictly complies with IS 401 to prevent early failure.
Sapwood must be fully penetrated by preservatives, as it is non-durable and highly susceptible to decay and termites regardless of the timber species.
Avoid using posts with large knots, severe cross-grain, or splits near the intended ground line where bending stress and decay risk are the highest.
