ELLEN Wilkinson School for Girls in Acton is one of the 100 schools in England affected by crumbing concrete.
The news was revealed by the opposition Liberal Democrat group on Ealing Council.
The foundation school in Queen’s Drive, will, however, open as normal for pupils this week as only part of the site is affected.
Lib Dem Cllr Andrew Steed said: "We are calling for an immediate survey of school buildings to ensure they are all safe for our children.
“Many parents in the UK have been left scrambling to arrange childcare, and locally we need to ensure the council and schools reassure parents and children about these new arrangements."
An Ealing Council spokesperson said: “We can confirm that no reinforced autoclaved aerated concrete (RAAC) has been found at any Ealing-owned school sites.
“However, it has been found at a foundation school in the borough, Ellen Wilkinson, where it is present in some of the buildings. The school will not need to close.
“Everyone’s primary concern is the safety of pupils and staff, and the affected areas have been taken out of use while safety measures are put in place and works arranged.”
The comprehensive school has already communicated directly with parents and carers.
It has a roll of around 1,400 girls, aged 11-19, and is named after one of the first female MPs in Britain, and the first female Minister for Education.
