Roadstone Flomix Hydrocure and Hydrocure Plus are a new range of high performance dry silo mortars specially formulated for use with clay brick and other masonry units that have a high initial rate of water absorption.

Roadstone Flomix dry silo mortars are manufactured using traditional materials, to proven prescribed mixes which provide the optimum combination of strength, bond and workability.

Advantages
Roadstone Flomix Hydrocure and Hydrocure Plus dry silo mortars offer a number of advantages over standard mortar mixes.

Natural unglazed clay brick can have a very high initial rate of water absorption. This can be problematic for traditional mortar mixes as the water is rapidly absorbed from the fresh mortar in to the brick causing the mortar to stiffen and become difficult to work. This can cause issues with the positioning of the brick, the quality of the bedding and the pointing of the mortar joint. Many manufacturers recommend that bricks are soaked prior to laying to overcome this issue. However this is not always practical and can cause issues later in the build.

Roadstone Flomix Hydrocure and Hydrocure Plus overcome this problem with the use of high performance admixtures to greatly increase the water retention of the mortar while also improving cohesiveness. The result is that the mortar retains much of its initial workability when used with clay brick and other masonry units that have a high initial rate of water absorption. This will increase the efficiency and ease of use for the bricklayer, during both laying and pointing, as well as the quality of the finished mortar joint.

Mortar Mixes

Roadstone Flomix Hydrocure and Hydrocure Plus dry silo mortars are specially formulated for use with high initial rate of water absorption masonry units such as clay brick. The mortar mixes use a finer sand grading which is suited to brickwork and allows for improved pointing of joints. However they are also suited to most other types of masonry construction. It is therefore possible to use the same silo for both brickwork and blockwork.

The following Roadstone Flomix mortar mixes are now available in both Hydrocure and Hydrocure Plus options. Other strength designations are available on request.

M4 Brick 4.0 1 : 5-6
