tuffgrit Bedding Aggregate - High Strength Selected Bedding Material
Verified by manufacturer 2 months ago
Crushed igneous rock bedding and jointing aggregate with high strength and permeability for the construction of traditional and SuDS type unbound pavement construction.
Application
- Suitable for bedding natural stone and pre-cast concrete setts, slabs and other pavers.
- For unbound pavement construction.
- For applications where heavy trafficking and longevity are required.
- SuDS type permeable pavements as jointing and bedding material.
Description
A carefully blended crushed igneous rock aggregate. Suitable for bedding and jointing of natural stone and pre-cast concrete setts, slabs and other pavers.
Features and benefits:
- Complies with the requirements of BS7533-101 Table 8 for unbound bedding material up to Traffic Category 9.
- Complies with the requirements of BS 7533-13:2009 (guide for the design of SuDS type permeable pavements), where unbound construction methods are used.
- Graded specifically for strength through the interlock of hard angular particles resulting in high surface strength, enhanced durability and extended life.
- Provides essential free draining and permeable performance for all type of unbound construction.
- Indefinite storage life, no requirement to be kept dry.
