LONG TERM REPAIR OF JOINTS
September 1st 2004

Materials and expertise from the Concrete Grinding Group are ensuring longterm repair of floor joints and maintaining efficiency in MFI’s 63 000m2 national distribution centre in Northampton.

MFI’s own staff or nonspecialist contractors used to carry out the repairs, but these seldom lasted, so seven years ago it called in Concrete Grinding. The first joints repaired are still sound today.

CG’s repair team is now carrying out a large-scale programme in the warehouse as part of a major re-fit involving new racking, sprinkler systems and lighting to make the floor suitable for VNA trucks and wire-guided equipment.

When joints are wide or the edges damaged, epoxy mortar is used to re-build the concrete slab. The joint opening is then filled to the full depth of the repair with semi-rigid sealant that allows the correct amount of movement while protecting the edges. Each repaired joint is ground flat after curing to ensure a completely even surface.
