The Damptec team are working on a new build site in Nottinghamshire requiring a combined Type A and Type C waterproofing system to provide barrier and drained protection to conform to the requirements of BS 8102:2009.
The photo shows Newton Hydrobond 410 Geodrain applied over the primary external waterproofing membrane on the external walls.
Warranty providers such as NHBC, Premier Guarantees and LABC require combined protection as a fundamental condition of their warranty. They also require involvement of a CSSW qualified waterproofing design specialist at the design stage. All materials used carry a BBA certificate which is necessary to satisfy the requirements of third party building warranty providers.
External: Type A Barrier protection external waterproofing including:
Application of primer to all surfaces in a spray coat application.
HydroBond 2K-Flex post applied to external earth retaining walls to lap onto the HydroBond 403 Plus.
Installation of Newton 410 Geo-Drain Quattro with geo-textile filter sheet over the primary external waterproofing membrane.
Internal: Type C (Drained) protection
Secondary protection, which manages any water ingress which occurs as a consequence of an installation defect, is provided by a cavity drain membrane system.
Walls: Mechanically fix Newton 508 (8mm) membrane to the internal side of the external cavity taped into the wide DPC at the beam and block junction.
DPM is taped to Newton floor membrane with Newton Waterseal Tape.
Proprietary weep holes at the mortar joints are required to allow drainage.

What is HydroBond 2k-Flex?
- Radon-Certified Strength: HydroBond 2K-Flex, certified for radon gas, forms a tough, flexible barrier. Perfect for external waterproofing, it quickly seals cracks and joints in earth-retaining structures.
- Eco-Friendly Flexibility: Environmentally conscious and solvent-free, HydroBond 2K-Flex reacts for a firm, flexible coating. Apply swiftly with a trowel or spray, securing insulation to various surfaces, and drying rapidly.
- Complete Defense, Quick Dry: HydroBond 2K-Flex ensures rapid waterproofing. Ideal for securing insulated panels, it works seamlessly with HydroBond 2K-Flex Primer and HydroBond 2K-Flex Mesh for a comprehensive solution.
A radon gas certified, bitumen/rubber waterproofing membrane used primarily for the external waterproofing of earth-retaining structures such as basements and foundation walls. Forms a thick, highly flexible barrier to water ingress that can be applied to fill voids, cracks and joints.
Environmentally friendly and solvent-free, HydroBond 2K-Flex consists of two components; a bitumen emulsion and a reactive powder. These two components chemically react when mixed to produce a firm, yet still highly flexible coating that can be applied by trowel or by airless spray machine. Adhering insulated panels to concrete, masonry and thoroughly dried thick bituminous coatings, 2K-Flex dries quickly and is rain-fast after a short period.
HydroBond 2K-Flex requires two ancillary products, HydroBond 2K-Flex Primer and HydroBond 2K-Flex Mesh.
