RED ASH

That this House pays tribute to the six year long campaign of John Birks of Stoke-on-Trent to clarify the policy in respect of sulphate damage to concrete floors laid on sulphate-bearing hardcore; welcomes the Building Research Establishment's guidance in respect of domestic properties built in the period 1945 to 1970; and urges all responsible for implementing building regulations to refer to the RIBA publishing document.
