Welcome to John Carr Liverpool Limited
John Carr (Liverpool) Limited is a family business presently run by some of John Carr's grandsons and great sons. Since the founder John Carr started in business around 1896 the family have developed the business with a range of products and services for the construction industry.

General Information Mortar is often considered the material that either keeps the bricks apart or bonds them together. As the two photographs show mortar will alter the over all effect of a wall. The photographs show walls built using the same brick throughout. By altering the colour, shade and pointing of the mortar a startling effect on the overall appearance of the brickwork is achieved.

The cost of using a coloured mortar is minimal when compared to the overall cost of an average house, and can sometimes save money. Selecting a more economical brick and enhancing the overall appearance with the selection of a coloured mortar can reduce the cost and improve the overall look of a building.

Successful masonry is dependent on the selection of the correct materials for each application.Before selecting a brick and mortar, consideration must be given to the following criteria.

A. What are the strength requirements of the structure?
B. What degree of exposure is there at the site?
C. Which bricks will meet the requirements of A and B?
D. Which designation of mortar will be compatible with A Band C?
E. Which joint profile is most suitable?
F. Are there any design details that may effect the durability of the unit?
G. Build and view a test panel to confirm your selection
H. Allow sufficient time before the start of the project, for the panel to dry.

Lime Sand Mortars
Traditional Lime Sand mortars still have an important roll to play in the construction industry. The use of well-graded sands blended with slaked hydrated lime putty, and where necessary admixtures produce a range of workable durable mortars, that with the factory addition of coloured pigments is pleasing to the eye.

Our standard range of coloured mortars give a wide selection of shades add to this the flexibility of a small family business, we can blend an almost limitless range of shades to suit nearly all requirements. Lime based mortars are strong yet sufficiently flexible to absorb structural movements in buildings. Since the lime in the mortar remains chemically active any resulting cracks may be "healed" when the lime reacts with rainwater, so improving weather resistance and reducing maintenance cost.

Lime based mortars have proved their excellent durability over the centuries. Lime in mortar allows good workable mixes with out recourse to sands with high fines content or the need for high air entrainment. In this way, mortars with excellent durability and colour stability can be produced.

Ready to Use Mortars
The factory-controlled addition of cement to retarded Ready to Use Mortars produces high performance durable mortars, available as Cement Lime Sand Mortars, as well as Sand Cement Mortars. The use of a selection of quality admixtures, give a workable mortar for up to 72 hours.
The careful selection of a Coloured Ready to Use Mortar enhances a well designed building, with no shade or colour differences.
Where there is more than one type or colour of masonry in a single structure, trowel ready mortars assist the speed of construction, by eliminating the need to change or clean out mixers, or the need of................................................................

Carbra-Mix is suitable for internal and external use. The Carbra-Mix Colour chart gives useful information on background renders and application information of the product.

The primary use of sand cement floor screeds is to level a base, generally concrete, but also insulation board and under floor heating mats. Unless modified sand cement screeds are not suitable as a wearing surface.

John Carr (Liverpool)Ltd floor screeds are mixed in a forced action mixer, that ensure all the constituent parts are dispersed evenly throughout the batch, minimising the risk of agglomerates or balls of cement which frequently occurs when using free fall mixers. The sands used in John Carr floor screeds ensure excellent working properties as well as good strength and durability. Cement setting times can be retarded from 6 hours, up to 24 hours to allow the screed to be laid over a specified period of time.

Higher performance and modified screed are available. The addition of 6mm or 10mm aggregate, and admixtures such as polypropylene fibres, S.B.R., Rapid Drying (HES) as well as the more traditional granolithic screed, give a wide selection of properties available with John Carr factory made screeds
