Treatment of an exposed roofing concrete slab with a composite membrane and a viscous plastic copolymeric resin

Abstract
It is the purpose of this paper to study the application of industrial wastes derived from synthesis of styrene and scraps of the composite used as internal lining in telephone cables in building construction roofing. Such scrap is presently melted for aluminum recovering so that the copolymer lining is totally destroyed. Similarly, the styrene waste which represents a disposal problem is normally incincerated causing environmental pollution. The modified polystyrene in the form of a viscous plastic resin adheres well to the cementitious substrate sealing its pores. The aluminum composite placed on top of this resin provides additional watertightness producing a reliable waterproofing system. Laboratory and field tests confirm the effectiveness of the proposed waterproofing concept. Given the lower costs of the raw materials and of the modifiecation procedures, it is hoped that the adoption of the new hybrid system is beneficial to its potential users and contributes to environmental control. Financial support for this study was provided by The State of Sao Paulo Research Foundation.
