Lift VNA and very-narrow-aisle slabs back to FM1/FM2 tolerance without dismantling racking or moving stock.

Free Quote How it works

What we deliver

Inject under live racking with stock in place, no decant required.
Laser-monitored ±1mm lifts meet FM1, FM2 and VNA flatness standards.
Restores correct aisle profile so wire-guided trucks operate at full mast height.
Reach trucks and order pickers back in the aisle the same shift.

Why this method works

Proven across hundreds of industrial sites.

Work around live plant

Inject under operating racking, conveyors and machinery without dismantling or moving stock.

Millimetre tolerances

Laser-monitored lifts to ±1mm where MHE flatness (FM1/FM2) and VNA tolerances demand it.

Heavy-load rated resin

Structural polyurethane handles forklift, reach-truck and HGV loading, no settlement creep.

Minimum downtime

Operations resume the same shift in most cases. No demolition, no curing wait, no dust extraction.
