Reinstatement, concrete chambers and the structural work that finishes every utility job properly.
Every job ends the same way: reinstated properly, whatever it took to get there. That covers straightforward work — tarmac, kerbs, paving — right through to structural builds like retaining walls and concrete chambers. At Lee Valley Ice Centre, failing ground either side of an underpass meant building new retaining walls to hold it back and protect the footpath above.
Chambers are either built up from pre-cast rings or poured in-situ with steel fixed and shuttered first, and every piece of structural work runs to a temporary works design and engineered drawing before anyone breaks ground.
Not usually — it's normally part of a bigger job, but we'd take it on separately if asked. Either way, a temporary works designer produces the drawings first; we don't build to anything that isn't designed and specified.
Poor compaction, the wrong backfill material, or opening the road before the tarmac's had time to cool and cure properly. Any of those and the surface lifts or sinks under traffic loading soon after.
