tuffbed 2-Pack, Type 35, Free Draining, Low Carbon Bedding Mortar - BS7533-101 Type 35 bedding mortar

A high performance bedding mortar, formulated for use as the laying course (bedding) for bound construction (rigid) pavements constructed in natural stone or concrete paving units subject to pedestrian through to heavy categories of trafficking.

Features and benefits:

• Performance exceeds BS 7533-101:2021 table 9, Type 35 bedding mortar requirements and in particular the requirement to be permeable and frost resistant when cured.
• The permeability of the bedding mortar helps to prevent moisture related issues, including frost damage, structural failure, efflorescence, picture framing and organic staining.
• tuffbed 2-pack has a capillary rise within the maximum permissible rise of 20 mm in accordance with BS 7533-101:2021. 5.4.1 when tested to Annex C.
• Low carbon footprint: This two-part product requires no pre-drying or pre-blending of the aggregate component, and because the binder is supplied separately, the need for energy intensive central processing is avoided. This reduces overall energy use and haulage. Mixing is carried out on site which also makes it economical and suitable to commercial and public realm projects.
• Bedding depths of between 25–70 mm can be placed in a single layer. Greater depths are achieved by placing successive layers. Consult manufacturer for details.

Mixing of tuffbed 2-pack is carried out on site. Precisely measured 25 kg pre-packaging of the binder and aggregate ensures that the exact mix ratio of 100 kg aggregate (x 4 no. 25 kg packs) to 25 kg binder (x 1 no. 25 kg pack) is achieved with every batch, making tuffbed 2-pack suitable for commercial and larger public realm modular pavement projects with high quality material and high-performance requirements.
