This project involves the removal of an existing mastic asphalt surface and the installation of a high-performance waterproofing and paving system using 10mm GuaraFLEX R and 25mm GuaraFLEX P. The works will deliver a modern, durable, and fully waterproof surface suitable for vehicular and pedestrian traffic, including light and heavy commercial vehicles.
The finished system will provide long-term protection, improved durability, and compliance with relevant structural and safety standards, while maintaining a seamless, monolithic finish.
Scope of Works
Removal Phase
- Careful stripping and disposal of existing mastic asphalt
- Preparation and inspection of the exposed substrate
- Ensuring surface is clean, dry, and suitable for new application
Installation Phase
Layer 1: GuaraFLEX R
- Installed using techniques consistent with mastic asphalt practices outlined in BS 8218:1998
- Functions as a waterproofing and bonding layer
- Provides a continuous, seamless membrane
Layer 2: GuaraFLEX P
- Polymer-modified asphalt waterproofing and paving system
- Designed for elevated decks and high-traffic areas
- Composed of asphalt cement with graded limestone aggregate
- Installed as the wearing surface for cars, light commercial vehicles, and heavy goods vehicles
