Schools looked after by Westmorland and Furness Council do not have any RAAC, the authority announced.
The council is responsible for 70 schools and it said inspections did not find any presence of reinforced autoclaved aerated concrete in any of them.
A programme of inspections for RAAC was launched across the 70 schools as a priority last year when concerns were first raised, it said.
All schools for which the council has responsibility for maintenance were included in this programme and to date no presence of RAAC has been found as a result of the surveys.
Based on the outcome of these surveys, the council said it was satisfied that where the council has responsibility for maintenance schools are not impacted.
The Department for Education is leading on the national investigation and is liaising directly with schools where a diocese or an academy is the responsible body.
While the council is not the responsible body for these schools, should RAAC be identified in these settings, the council said it would work with school leaders to provide support.
The council also began work to assess its 410 other buildings.
It said it was unlikely that any of the buildings have RAAC present, but around 50 buildings, about 12 per cent of the council’s asset portfolio, will be inspected as a precautionary measure.
Councillor Peter Thornton, Westmorland and Furness Council cabinet member for highways and assets, said: “We are aware that there has been a lot of coverage in the news regarding the potential presence of RAAC in schools and public buildings, and that this is understandably a concern for lots of people.
“Thankfully, we were aware of this issue almost a year ago and we have done all we can to ensure all 70 of our council-maintained schools are safe.
“After a programme of inspections, we can confirm that RAAC has not been found in any of the 70 schools that the council is responsible for.
“We have also screened our corporate assets and will be instigating a programme of inspections for those we have identified as benefitting from precautionary surveys. This work will take some time to complete but we want to stress and reassure the public that this is simply precautionary and measures the council is taking to ensure its buildings are safe and maintained.”
Any parents with children at diocese or academy schools should contact those schools directly for advice.
