Auto Repair Drainage

Drainage Solutions

It’s important to consider different drainage options both inside and out when it comes to auto repair shops. In both situations you have to remember to check with state and local laws requiring the proper capture and disposal of direct and indirect chemical runoff.

Around the outside of the building you need to ensure that storm water runoff is directed away from the building and that the grates selected can handle vehicular traffic loads but are pedestrian friendly in areas closest to the building.

Inside the bays, you will need to consider how to capture and contain any of the fluids that are drained from vehicles. It is also important to ensure that it has the quality to hold up to the corrosive environment and is nonflammable.

3 Considerations

Catching Chemicals

Inside the body shop it’s important to ensure that any chemical waste is properly captured and contained to meet federal, state and local requirements. Our experts can help you find the right drainage system that can hold up to the harsh vehicular chemicals.

Fully Loaded

The size and weight of the equipment that passes over trenches determines what type of grates is needed. Don’t forget to consider whether the grates will have pedestrian traffic to avoid safety issues.

Safety First

Consider nonflammable drain alternatives. With all the chemicals going down the drains, HDPE and similar type plastics can combust under certain conditions.
