Flash Harry Drip Stop Fibre is a fibre-reinforced rubberised bitumen waterproofing compound designed for superior flexibility and long-lasting waterproof protection. Its built-in fibre technology helps strengthen the waterproofing layer while reducing the need for additional membrane reinforcement in many applications.
Ideal for roofs, foundation walls, fish ponds, water features, and general exterior waterproofing, Drip Stop Fibre creates a durable waterproof barrier that resists water penetration and harsh weather conditions. Its water-based, non-toxic formulation makes it suitable for both residential and commercial applications.
