Gasoline resistant sealant for gas stations

Gasoline resistant sealant contributes to safety at gas stations

Gas stations, or filling stations, are designed for refuelling motor vehicles from tanks underneath the stations. At gas stations, harsh chemicals such as gasoline, diesel and motor oil are present at all times. Therefore, the area in and around filling stations must meet certain requirements to guarantee safety. The forecourt is usually made of high density concrete pads which are joined together with a gasoline resistant sealant. Not only is the sealant resistant to gasoline but it also makes sure no fuels and oil can access the soil or groundwater.

The gasoline and diesel resistant sealant systems primarily have three aims:

  1. Keeping the soil and groundwater clean by providing impermeable seals which prevent chemical penetration.
  2. Reducing fire hazard by not contributing to the spread of flames in occasion of fire.
  3. Increasing overall safety when the right product is chosen: protecting the environment and the concrete as well as the people refueling their vehicles.

Characteristics of gasoline and diesel resistant sealant systems

Sealants for gas stations must be oil, diesel and gasoline resistant, strong and abrasion resistant.

At filling stations, fuels such as diesel and gasoline are present as well as oil spills are possible. They are also subject to almost continuous traffic from heavy loaded trucks to lighter motorcycles which not only drive on the concrete, but also stop to be refueled. Therefore, the most important requirements for gas stations sealants are:

Note that similar requirements also count for applications at airports and harbors.

The types of diesel and gasoline resistant sealants for gas stations

The gasoline and diesel resistant sealants applied at gas stations are made for heavy duty as the environment is harsher than the most. Even though similar sealants are used for example in bridge expansion joints, the ones for gas stations must be a little more resistant. There are several types of sealants that are suitable for new forecourt concrete and concrete repairs.

What to take into account when choosing a sealant for filling stations

Each country and region has their own rules and regulations for filling station construction. Always check with the local authorities which type of sealant is recommended. There are, however, some general aspects to take into consideration when looking for the perfect diesel and gasoline resistant sealant for concrete at gas stations.

Gasoline and diesel prevent fuels from seeping to the soil or groundwater.
  • Environment: it goes without saying that one of the most important aspects to consider is the environment: is the sealant sufficiently impermeable and diesel and gasoline resistant?
  • Safety: gas stations always have an increased fire hazard due to the presence of flammable flues. Therefore, the gasoline resistant sealant must be fire retardant to a certain point in order to reduce the hazard even when there is gas on concrete.
  • Application and curing time: a filling station is a business where time is money. Therefore, it is good to consider how fast the sealant can be applied and how long it takes before it is hardened. Keeping the downtime at the minimum is desired.
  • Durability and need for maintenance: sometimes it is better to invest in a sealant which application takes longer, but which does not require frequent maintenance. However, it can also be a conscious choice to keep the downtime at its minimum, even if it meant more frequently short periods of maintenance.

Find a diesel and gasoline resistant sealant for gas stations to meet requirements

Gas stations are subject to a wide variety of rules, regulations and standards depending on the country and region. Therefore, the best sealant is not always a straightforward one-off decision.
