URETEK PAVEMENT REPAIR Highways & Airports

URETEK STITCH-IN-TIME restore load transfer between adjacent slabs

Patented process

URETEK developed and patented URETEK Stitch-in-Time(r) technology as a process for restoring or creating load transfer across breaks between adjacent sections of concrete pavement slabs.

The process involves saw-cutting a series of deep, one centimetre (half-inch) wide slots. The slots are spaced at regular intervals and normally at right angles to the edges of the concrete, some 50 cm (two feet) into either side. Into these slots, 6 mm (quarter inch) thick composite reinforced resin blades are inserted below the concrete surface.

After the inserts are positioned, the remaining space in the slots is filled with dry sand and the whole mass is wetted out and bonded into place with a low viscosity, hybrid, high-density polymer resin.

The URETEK Method may be used to firstly realign the pavement, if necessary to give a smoother ride, and to ensure proper support before stitching.

Key Benefits

Unlike outdated, steel dowel-bar retrofitting, URETEK Stitch-in-Time provides a prompt, full depth repair, offering far greater strength and stiffness.

More cost-effective and better performing long-term, than dowel-bar retrofitting.
Greater pavement performance due to stronger, stiffer and smoother joints.
Rapid curing allows almost immediate traffic restoration.
Will not corrode or bend.

Applications

The URETEK Stitch-in-Time process can be used for creating or restoring load transfer in a variety of situations:

Across never before connected panels of pavement. (Joint stitching)
To replace rusted original dowel bars across joints.
To structurally repair serious cracks in concrete pavement. (Crack stitching)
In repair of corner breaks and potholes. (Patch stitching)
To bond a complete precast replacement panel into a concrete highway.
