High performance bedding mortar to BS 7533-101:2021 Type 35, free draining with a low-carbon manufacturing profile.
Laying course (bedding) for bound construction (rigid) pavements.
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:
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.
