Pacopatch

Over 100,000 drainage gullies and public utility ironworks have been successfully reinstated with Pacopatch!

Pacopatch is a revolutionary polymer based bituminous reinstatment system developed specifically for the single reinstatement of manholes and gullies. Pacopatch comes with a 5 year material warranty, is voidless, requires no compaction and can be trafficked within an hour of completion. Pacopatch has been laid 0.5 metre deep and was trafficked the same day.

The revolutionary system comprises a hot applied asphalt grout into which factory prepared cold asphalt bricks (containing a minimum 45% of coarse aggregate) are placed.

The cold bricks are designed to absorb the heat from the hot asphalt grout whilst forming a monolithic asphalt structure. The system cools to ambient temperature much more quickly providing engineers with the ability to arrange for repairs to be completed within restricted working periods and the road reopened to traffic.

Pre-coated or dry chippings are applied to the finished surface to provide a non-skid surfacing complying with UK legislative specifications.

These include coloured and printed mastic asphalt products and acid and fuel resistant materials.

Pacopatch  Reinstatement System

Pacopatch is a polymer modified mastic asphalt permanent reinstatement system primarily designed for use around manholes and other street ironworks. The system comprises the placing of Quality Assured factory manufactured, mastic asphalt bricks (to BS1447:1998 incorporating 45% recycled coarse aggregate) into a layer of polymer modified mastic asphalt grout.

The process is completed by backfilling with additional grout to produce a voidless, impermeable, monolithic and permanent reinstatement which can be completed in a variety of surface finishes. Pacopatch requires no compacting, is applied by hand float and enables applicators to economically patch even very small, irregular areas, to a consistent, voidless standard. There is no waste when using Pacopatch.  The need for and the cost of collecting an excess of hot materials from a quarry is eliminated, as is the reliance on the plant being open for night and weekend collections. Pacopatch is delivered in a palletised format providing the user with a 24/7 availability all year round. Pacopatch is a one off application, which produces a permanent reinstatement requiring  no temporary measures or subsequent repair visits.
