To prevent this problem occurring Tolly Paving used a special jointing material from Brett Specialised Aggregates on this project.
This material has been developed specifically for this type of application and is comprised of kiln dried sand made from crushed angular particles.
Jointing Material The joints between concrete block pavers are filled with a specially designed kiln dried sand that is compliant with BS 7533-3: 2005.
This standard requires that jointing sand meets a particular particle size distribution - but it does not specify particle shape.
Zeta Lock harnessed the technology of similarly available interlocking pavers but the nib configuration was enhanced to ensure that no block-to-block contact, which could result in localised spalling of the block surface, was possible when installed.Port of Great Yarmouth - heavy duty concrete block pavements The Solution When this project started no UK block paving manufacturer had a product available in their range to meet the required specification in a machine lay format.Tolly Paving approached Brett Landscaping about manufacturing the shaped blocks for this contract.Cullen Grummitt & Roe were appointed as the client representative to undertake the design and supervision of the work in recognition of their worldwide experience of container port design and construction.The new harbour consists of two breakwaters with a total length of approximately 1,400m, these required the importation of approximately 900,000 tons of rock and aggregate material.

Finally 450m of quay wall, with associated capping beam and crane rail, were constructed as well as 225m of revetment berth and associated berthing dolphins.
