Colourful solutions
Where a coloured mortar is specified the control and accuracy of the pigment addition and mixing process ensures consistent dispersion throughout the mix. CEMEX Dry Silo Mortar is available in a wide range of colours to meet specific design requirements.

Manufacture
The dry silo mortar system is manufactured under a 3rd party accredited factory production control system, using the latest technology to provide you with a convenient mortar batching facility, with the following benefits:
- Guaranteed colour and consistency
- Clean and efficient production with reduced wastage and increased productivity.
- Reduces manual handling and the risk of injury in production, for improved health and safety.
Durability and resistance
CEMEX Dry Silo Mortar is also extremely durable due to the controlled method of manufacture and the type and quality of the constituent materials used. The entrainment of controlled amounts of air makes the mortar less susceptible to frost attack. The admixture used is chloride-free and therefore not aggressive towards embedded metallic objects. Factory produced mortars exhibit superior resistance to rain penetration and therefore make a significant contribution to the durability of masonry.
Workability
CEMEX Dry Silo Mortar when blended with water offers excellent workability without an excessive air content, the inclusion of which can weaken the bond and flexural strength.
Case Studies
Since April 2018, CEMEX Dry Silo Mortar have been supplying several sites at Wembley Stadium as part of the on-going £3 billion regeneration at Wembley Park.
In early 2018, Quintain, the company behind the project, announced plans for a further 250,000 sq. ft of shops, restaurants and bars to be built on the 85-acre site, which will double what has already been constructed.
There will also be 7,000 new homes built, along with offices, a gym, a park, and possibly, a brand-new music venue

Case Studies
Since late 2016, have been supplying Primary Sprayed Concrete to Dragados for the Bank Station Upgrade in London.
The project, which is set to be completed in 2022, sees the expansion of the current Bank Underground station, whilst merging it with Monument Underground station in order to reduce congestion.
Three additional ticket halls will be created, along with six lifts, ten platforms, two 94m travellators and a 570m tunnel.
