What happens here

Once the block base is laid, proceed with backfilling. Improper backfill, using loose or organic materials, can lead to settlement over time, creating hollow spaces beneath your concrete slab and causing cracks. Instead, use a proper, granular backfill material like gravel or crushed stone. Use a mini skid steer to dump the material, and then compact it thoroughly using a plate compactor or a hand tamper. Proper compaction of suitable material ensures a stable and strong base that will not settle.

Goal: Create a stable and non-settling base for the concrete slab using appropriate backfill and compaction.

Tools and materials

  • Hand Tamper — Compacting backfill material
  • Jackhammer Makita — Demonstrating the effect of improper backfill
  • Mini Skid Steer — Transporting and dumping backfill material
  • Sledgehammer — Demonstrating the effect of improper backfill
  • Gravel — Proper granular backfill material

What they say

Hide

block and sets your block. If we backfill with loose or organic material, even if I compact this backfill, as organic materials break down over time, the backfill will get lower and lower and your concrete will be hollow underneath and cause it to easily crack. If we use the proper backfill and do the proper compaction, the base will stay strong. If there's no flashing, just install concrete against
