Definitions
- the present invention relates to the containment of hazardous liquids.
- the invention relates to the containment of liquids which may leak/spill from a primary containment reservoir.
- liquids are often flammable and may also be toxic. It is therefore highly desirable that in the event of a tank rupture, the liquid is contained within a secondary containment area.
- this secondary containment area requires a barrier, such as an earthen wall or bund to be constructed around the tank.
- a barrier such as an earthen wall or bund to be constructed around the tank.
- the size and location of the bund is such that the liquid, if discharged from the tank can be contained within the area.
- the earth bund will absorb and allow the liquid to leach therethrough.
- the bund is covered in concrete, asphalt or high density polyurethane (HDPE), all of which have varying fire retardation properties.
- Asphalt is prone to cracking, degrades over time and is not resistant to petroleum based products.
- a HDPE system typically consists of a 1.5mm HDPE sheet membrane, welded on site and commonly used to line dams.
- the HDPE membrane is not fire resistant, and is prone to expansion and buckling in the presence of sunlight.
- the HDPE membrane is retained in place along its bottom edge using a weight such as gravel. This prevents the membrane from being visually inspected. Hence, upon visual inspection the integrity of the membrane cannot be ascertained in those areas.
- the membrane is relatively thin it does not have high wear properties and is not tolerant to traffic.
- the present invention provides a lining system to line a surface of a containment area, the lining system comprising:
- a first layer comprising a first material having fire resistant properties, the first layer having been sprayed onto the surface
- a second layer being of a second material, the second material being flexible and capable of preventing a flame passing therethrough;
- a third layer comprising a third material sprayed onto the second layer.
- the third layer bonds to the second layer.
- the first and third layers are the same material and may be flexible.
- the polyurea is self extinguishing.
- the polyurea may have high wear resistant properties.
- the first layer is applied to concrete. This may be the case when applying the current invention to a containment area previously lined with concrete.
- the second layer terminates a distance from the periphery of the first layer, allowing the third layer and first layer to bond together around the periphery of the second layer, effectively encapsulating the second layer within the first and third layers.
- a primer may first be applied to the surface before the first layer is applied, assisting in the bonding of the liner to the surface.
- the third layer remains flexible and intact after it has been burnt.
- the liner prevents the liquid from passing into the subsoil, and ensures the liquid is contained in the event of a fire.
- a second layer being of a second material, the second material being flexible and capable of preventing a flame passing therethrough;
- a third layer comprising a third material sprayed onto the second material, bonding thereto, the third layer having fire resistant and anti static properties.
- the lining system may also be applied to structural beams, used as a fire rated curtain wall, fire doors, etc.
- the present invention also provides a method of lining a containment area comprising the following steps:
- the second layer being a woven, flexible, fire resistant material
- Figure 3 is a schematic cross sectional view of a lining system according to an embodiment of this invention.
- Figure 4 is a view of the lining system of figure 3 schematically shown in position according to an embodiment of the invention.
- a lining system 19 according to the first embodiment is shown in figure 3 with an application of the system 19 shown in figure 4.
- the lining system 19 comprises a first layer 21.
- the first layer 21 is sprayed onto a layer of geotextile material 23 which has been laid on a substrate 25, and buried along its edge, as shown in figure 4.
- the first layer is a polyurea fire resistant elastomer, which once cured, provides a flexible barrier to liquid and fire. As the first layer 21 is sprayed on to the geotextile 23 there is no joins or seams therein.
- a second layer 27 is positioned thereon.
- the second layer 27 comprises a flexible woven fiberglass mesh having fire retardant properties.
- the second material is substantially non- absorbent, allowing a small amount of liquid to pass therethrough whilst preventing any flame from passing through the material.
- a third layer 29 is sprayed onto the second layer 27.
- the third layer comprises the same material as that used for the first layer 21 with the addition of further components to provide the third layer 29 with anti static characteristics.
- the third layer 29 provides the first line of defense to any flame or liquid which may be spilt in the storage bund 15. Again, as the first third layer 29 is sprayed applied there is no joins or seams therein.
- the second layer 27 may terminate a distance from the peripheral edge 31 of the first layer 21 as shown in figure 4.
- the third layer 29 is applied the third layer is sprayed up to the peripheral edge 31 , encapsulating the second layer 27 therebetween.
- the second layer 27 is only positioned on the sides of the storage bund 15 and under any equipment 33 from which liquid may spill.
- the lining system or a layer thereof extends beyond the top 35 of the storage bund and is typically secured in a trench 37.
- a bonding primer (not shown) may be first applied to ensure the first layer 21 bonds to the substrate. This may be particularly critical where the lining system 19 engages the storage tank 13.
- the second layer may simply be folded and removed taking the third layer with it. A new second layer may then be laid and a new third layer sprayed thereon. Modifications and variations such as would be apparent to the skilled addressee are considered to fall within the scope of the present invention.
