Highway Systems Cracking & Seating
In the U.K there are two methods of Cracking & Seating, one which is used on our Motorways and the other, Highway Systems environmentally friendly process. Our method of Cracking & Seating has been specially and specifically designed and developed over many years to treat town and city centre roads, industrial estates, and especially housing estate roads, where services are normally located directly below the carriageway.
Our method of Cracking & Seating causes minimal disruption to traffic which can reduce the need for road closures and traffic diversions.
The aim of Cracking and Seating concrete carriageways prior to re-surfacing, is to minimize the likelihood and severity of reflective cracking re-appearing in the new overlay caused by movement or overstressing in the concrete road slab caused by voiding or erosion of the sub-base/sub grade causing stress cracking, failure cracking, and differential settlement. The “Cracking” part works by turning the rigid concrete road into a “flexible” road base and the “Seating” part reinstates sub-base/sub-grade support stabilizing the road slab. Cracking and Seating greatly reduces the need for costly excavation works. Crack & Seat recycles in-situ the existing concrete pavement.
The Process:
- Environmentally green.
- Recycles the original concrete pavement.
- Site can be trafficked immediately for up to several weeks before resurfacing… safely.
- A minimum thickness of overlay is normally needed.
- Needs only minimum supervision.
- No costly repeat maintenance.
- Finds hidden voids.
- Induces multi hairline fractures, allowing thermal movement and axle loading.
- Creates a mechanically bonded and interlocked “block”.
- No puncturing or pulverising.
- Enormously cheaper than conventional maintenance methods.
- Saves money on overlay depths.
- No need for road closures.
- Time saving.
About us
Highway Systems was founded in 1993 and have treated several million square meters of concrete carriageway successfully, for County Councils, Local Authorities, Consulting Engineers and most major Construction Companies. Our management team have over 25 years experience in Cracking & Seating and are happy to advise you on any project that is being worked on, please contact us without obligation for expert, experienced, professional, and specialist advice.
