Concrete Sprinkler Tank Linings London

THE SOLUTION

We proposed our proven preferred concrete sprinkler tank lining system which we have used in dozens of tanks of this type.

Initially all surfaces were prepared by method of vacuum controlled diamond grinding to remove surface laitance and contamination. Following preparation all surfaces were vacuumed clean in order to ensure an excellent clean and dust free surface for the tank lining to adhere to.

There were numerous tie holes and blow holes in the concrete sprinkler tank walls that required making good as these cannot be filled with coatings alone. We applied a cementitious fairing coat in the form of Remmers Sulfatex grout, which was sponge float finished to provide a good mechanical key for the subsequent crack bridging epoxy tank lining.

Following the initial the fairing coat was de nibbed using a carborundum stone to remove any protrusions that would reflect in the final tank lining, equivalent to a cementitious version of a rogue peak. When permitted heating a dehumidification was introduced in order to both dry out the cementitious materials and ensure the correct climactic conditions for coating application.

The moisture content of the substate and the climatic conditions were tested and recorded as part of our standard quality assurance prior to the application of any resinous tank lining materials.

As per Remmers recommendations a cove material was installed at the floor/wall interface to isolate this most probable point of potential movement from the tank lining. A cove detail serves to spread the point of movement over a greater area to allow more potential for the flexible tank lining to expand and contract without splitting.
