tuffbed 2-Pack High Performance SuDS Permeable Bedding Mortar - Type35 (SuDS) permeable bedding mortar
Verified by manufacturer 27 days ago
High performance permeable bedding mortar to BS 7533-101:2021, Table 9, Type 35.
Application
Suitable for use as a fully permeable bedding mortar course in bound construction SuDS pavements also using tuffflow fully permeable SuDS jointing mortar. The use of tuffbond priming/bonding mortar to achieve permanent 2MPa adhesion between the paving units and the permeable bedding mortar course is advisable.
Description
A fully permeable, high performance bedding mortar, formulated for use as the bedding (laying course) for bound construction (rigid) SuDS permeable pavements composed of natural stone or concrete paving elements.
Features and benefits:
- Performance exceeds BS 7533-101:2021 Type 35 mortar requirements.
- Fully water permeable and frost resistant, with high permeability characteristics allowing the design and construction of bound (rigid) permeable (SuDS) pavements when used in combination with tufflow SuDS permeable jointing mortar.
- Bedding depths of between 25–70 mm can be placed in a single layer. Greater depths are achieved by placing successive layers.
- Achieves or exceeds a horizontal permeability of 8.5 x 10-4 m/s and vertical permeability of 18.8 x 10-4 m/s when tested in accordance with BS 7533-101 Annex C.
- Low-carbon manufacturing profile and completely free from polymer and resin additives.
This two-part product requires no pre-drying or pre-blending of the aggregate content. The binder is packaged separately avoiding the need for energy intensive central processing. This reduces overall energy use and haulage and facilitates a reduction in cementitious binder content.
