Maxi-Crete (Concrete Surface Repairs)

Maxi-Crete is used to repair defects in concrete surfaces. Where a joint or crack has deteriorated to the point that a bay could become unstable, it provides a rapid, durable repair. This matters most on airfield pavements, where a loose slab beneath an aircraft is a critical safety issue, so the priority is a repair that returns the surface to service quickly without compromising strength.

In our experience, Maxi-Crete works better than a standard concrete patch on operational airfields because its rapid strength gain returns the bay to service within hours rather than days, where a conventional mix would keep the pavement out of use far longer. The defect is cut out and cleaned back to a sound, dry base before the repair is laid, so the new section bonds fully and carries load rather than sitting proud of a failing slab.

Applications: Concrete runways, aprons, taxiways, industrial floors, ports.

On a live airfield a repair is bought against the possession rather than the working day. The defect has to be cut out, cleaned back, reinstated and strong enough to carry traffic before the pavement is handed back, which is why a rapid strength material is used instead of a conventional mix that would keep the bay closed for days.

Not every failing surface needs a bay repair. Where the face of a slab has started to let go but the concrete below is sound, a resin treatment may be enough, and that is covered under concrete airfield repair. Where the deterioration has reached the joints, they are reformed and resealed as part of the same job.

If a taxiway, apron or stand is showing defects, tell us which pavement it is, how much of it is affected and what possession can be offered, and we will say what we think we are looking at before anyone writes a specification. Background is in why does airfield concrete fail at the surface first?
