Vacuum concrete process used on Scottish hydro-electric scheme
Placing of 12 to 15 in. thick reinforced concrete membrane on upstream face of dam; surface area of membrane is 14,800 sq yd, made flexible by introducing construction joints at max of 20 ft centers both ways; joints made watertight by insertion of copper seals and bitumen filler; placing of concrete membrane carried out in two stages; vibration used for placing and also for short time after vacuum has been applied, quickening process.
