Catch basins enable safe handling of liquid substances that are hazardous to waters. They can be made from different materials, which should always be appropriate to the substance to be stored.
General information on catch basins
Catch basins represent a safety measure for storing hazardous materials in mobile containers. Liquid substances that are hazardous to water must be stored in catch basins or in containers with integrated catch basins. The catch basins prevent the hazardous substances from draining into the ground or entering the waterways. They are liquid-tight and must meet specific legal requirements with regard to their composition.
Steel catch basins
Steel catch basins are used in many industrial and commercial applications. They are available in different versions, such as:
- With different holding capacities
- Stationary or mobile catch basins
- Stackable catch basins
- Pallet basins
- Catch basins with splash guard walls
- Storage and transport pallets with catch basins
- High-volume catch basins
- Small container catch basins
There are also steel flat basins, which are characterised by their large catch volume, impressive flexibility and high load capacity. They are used to protect the ground and can also support the weight of forklift trucks. Steel flat basins are assembled in a flash and can be expanded or converted to suit individual needs.
Steel and stainless steel make the catch basins extremely robust. These materials are ideal for storing both aggressive and flammable liquids. When equipped with a practical splash guard wall, the catch basins enable particularly safe filling and storage of hazardous substances.
As well as steel, catch basins can also be made from other materials, which are detailed below.
Polyethylene and GRP catch basins Steel catch basins
In addition to steel and stainless steel, both polyethylene and glass fibre reinforced plastic (GRP) serve as materials for catch basins. Plastic catch basins are particularly well suited for storing small containers. They are a popular choice for workshops, industrial areas and even laboratories.
Polyethylene catch basins are characterised by their very high chemical resistance. This makes them impervious to acids, alkalis, oils and other aggressive substances. However, they are not approved for use with flammable liquids.
Polyethylene catch basins are available in different versions, such as:
- With different volumes
- With and without grids
- For installation on the floor or on a Euro pallet
- With feet, castors or skids
Plastic catch basins offer a high load capacity and are corrosion-resistant, plus they can easily accommodate the weight of a pallet or forklift truck.
The main benefit of catch basins made from glass fibre reinforced plastic (GRP) is their flexibility. They effectively bridge the gap between steel and plastic by combining the advantages of both materials. GRP possesses a very high chemical resistance and can therefore be used to store oils, acids and alkalis (up to pH 8), water pollutants of GHS categories 1-4 as well as flammable liquids with a flash point > 55°C.
Another benefit of GRP catch basins is that they are subject to less stringent controls than their steel counterparts.
