Buried Services: Pipework, Ducts and Tank Insulation

Tanks that are buried underground, particularly when they are used for storing dangerous flammable liquids, reduces the risk of accident or damage and is frequently required for compliance with national and international standards. The properties of Laterlite Expanded Clay make it the perfect material for burying all types of tank.

Advantages

• Lower imposed loads on the ground and foundations. Prevention of settlement (which could compromise the usability of the tank)
• Durability, including in acidic or basic environments
• Resistant to weather and freeze/thaw cycles
• Incombustibility and resistance to fire
• Thermally resistant, with lower heat loss and reduced risk of freezing: ideal for Thermal Storage Tanks
• Drainage and elimination of stagnating water
• Easy to spread

• Extremely high percentage of voids (the volume of the voids between the granules, added to the volume of the voids within the granules, is approximately 85% of the total)

Laterlite Expanded Clay is also ideal as a backfill material for stabilising disused buried tanks and reservoirs, as well as as a fill for any underground cavities.
