Brentford Lock, Phase 2a: Blocks J and E for Ballymore

Around 17,000m² of flowing screed across two six-storey residential blocks, from a mix of on-site Maverick batching and premixed flowing screed, set out the same way on every floor so each one is handed over ready for the floor finish.

The brief

Phase 2a of Ballymore's Brentford Lock scheme needed screed laid across Blocks J and E: two residential blocks of six floors each, with apartments and corridors, and underfloor heating (installed by others) in the apartments. The floors had to be flat and consistent from the first floor to the last, so the follow-on trades could keep moving.

How we delivered it

  • Levels set out on every floor before the pour, with flow tests on site.
  • A mix of on-site Maverick batching and premixed flowing screed, so supply could flex with the pour programme.
  • Flowing screed laid over the apartments' underfloor heating, installed by others.
  • Floors handed over block by block, ready for the floor finish.

Why it matters

On a residential block, the screed sits right in the middle of the programme. If it's late or out of level, every trade after it waits. Combining on-site Maverick batching with premixed flowing screed, and setting out the same way on every floor kept Blocks J and E moving.
