Our sprinkler tank linings are manufactured from EPDM, this material is of a higher quality than traditional systems such as butyl rubber.
The sprinkler tanks inlet valve is closed and tagged, followed by the isolation and electrical tagging of all pumps and power supplies. The sprinkler tank is then drained over a 24hour to 36-hour period, depending on the size of the vessel. This avoids any drains backing up and flooding the tank area. On completion of the draining, confined space and ventilation equipment are positioned at the tanks access point, and any permits or method statements are checked and signed.
Any remaining water, sediment or silt is removed using submersible pumps and wet vacuums. The tanks internal surfaces, including the walls and base are cleaned and any rust or debris is removed. A tank panel is then removed to allow access for the sprinkler tank lining. This is usually a ground level panel, this allows for ease of access. Internal tank connections such as the overflow and outlet fittings are removed and flange surfaces cleaned. The sprinkler tank lining is manufactured in one piece, unless a sump is present which may require installing in situ.
