Скачать или смотреть Broken Pile Repair : Is This Concrete Pouring Safe !

A Little Wisdom Helps You Become Smarter !

In the video, an excavator bucket is seen pouring concrete into a pre-drilled hole to fix a damaged pile foundation. While this method might appear quick and practical, its safety and effectiveness depend heavily on specific conditions.

When is it acceptable?

If the hole is shallow (under 1.5 meters) and concrete has a low slump (stiff mix), direct pouring with vibration can work.

In emergency repairs where proper tools like tremie pipes are unavailable, but only if strict quality checks are done.

When is it risky?

For deeper holes (over 1.5 meters), free-falling concrete separates into uneven layers, weakening the pile.

High-slump concrete (flowable mix) will scatter and trap air, creating voids and cracks.

How to do it right?

Use tremie pipes or chutes for deep foundations to guide concrete gently.

Vibrate every layer to remove air pockets and ensure density.

Test concrete quality—slump, strength, and uniformity—before pouring.

Final note: Pile repairs demand precision. Shortcuts today may lead to collapses tomorrow. Follow codes, use the right tools, and prioritize long-term safety over temporary convenience.
