Estoproof 30 is used as an over-site membrane situated between the base concrete and the hardcore bed. A blinding layer of sand or granite quarry dust on a well compacted hardcore provides a suitable base. The membrane suited in this position protects the site concrete against any sulphate attack and allows good bonding of screed to the concrete.
It will at times be necessary to joint membranes together and to tailor the membrane round projections etc. prior to any jointing being made, sheets must be clean and free from dirt and grease. Adjacent sheets are overlapped by at least 100 mm. the lapping shall be sealed with wide premium quality adhesive tape or its equivalent to complete the overlap sealing process. The above techniques have been found suitable and effective for installation even by unskilled workers.
