Use of backfill containing pyrite (not DB certified)
The Long-Lasting Solution
A laboratory test shows whether the stone in the backfill has high swelling potential. If this is the case, the backfill must be excavated and replaced with DB-certified crushed stone (without swelling potential). The backfill must be removed.
The Scope of Work
- Break the damaged concrete slab
- Remove the backfill
- Spread and compact new DB-certified stone backfill
- Pour a new concrete slab
Our team of experts uses small excavation equipment to maximize operational efficiency safely.
