tuffbed 2-Pack High Performance SuDS Permeable Bedding Mortar
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 Type A and Type B 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.

This product has a low-carbon manufacturing profile and is completely free from polymer and resin additives.
