Description
A high performance and pre-blended bedding mortar. Formulated for use as the laying course (bedding) for bound construction (rigid) pavements composed of natural stone or concrete paving units subject to pedestrian, through to heavy categories of trafficking. The pre-blended feature makes this product more convenient for smaller commercial or domestic scale projects.
Features and benefits:
- Performance fully complies with BS 7533 Type A and Type B, also BS 7533-101:2021 Type 25 and Type 35 bedding mortar requirements, and in particular the requirement to be permeable and frost resistance when cured.
- tuffbed has a capillarity maximum rise of 20 mm in accordance with BS 7533-101:2021. 5.4.1 when tested to Annex C.
- The permeability of the bedding mortar helps to prevent moisture related issues, including frost damage, structural failure, efflorescence, picture framing and organic staining.
- Bedding depths of between 25–70 mm can be placed in a single layer, with greater depths achieved by placing successive layers. Consult manufacturer for details.
