The works had to be completed within a two-week window. To meet this tight deadline, WTL coordinated with the local supply chain to remove approximately 120m³ of contaminated spoil, before backfilling with around 68m³ of C20 mass concrete.
Once the ground was stabilised, a reinforced slab of around 60m³ was constructed, complete with sealed drainage incorporating two gullies and chambers.
During excavation, an existing drain and chamber were uncovered. These voids were filled using the C20 mix as part of the mass fill.
A dense network of reinforcing steel was then laid out to strengthen the C30/C37 concrete slab. The slab was poured in a continuous operation and finished to specification using a power float, creating a durable and level surface.
The finished slab was delivered on schedule, providing a strong and stable base for the new Coal Yard buildings. Despite the challenges of contaminated spoil removal and unexpected ground conditions, the project was completed within the original two-week timeframe.
