How do I determine what material to use for my spill berm and spill containment needs?

PolyChem 3

PolyChem 4

PolyChem 5

PolyChem 3 is a STANDARD DUTY 30 OZ. MATERIAL and should be used for containment applications of hydrocarbon, mild acids and caustics. Suitable for weekly vehicle entry and exit in conjunction with our Tough Guards matting.

PolyChem 4 is a HEAVY DUTY 46 OZ. MATERIAL that provides spill containment protection when containing acids, hydrocarbons, and other caustic chemicals. Suitable for daily vehicle entry and exit in conjunction with our Tough Guards matting.

PolyChem 5 is our PREMIER GEO-MEMBRANE MATERIAL. It’s 32 oz. polyurethane coated nylon material and should be used for hydrocarbon application containment. Suitable for daily vehicle entry and exit in conjunction with our Tough Guards matting.

How do I determine what size berm to order?

Measure the overall footprint (length and width) of the container or equipment you wish to contain. Add an additional 4' to the berm's length and 4' to the berm's width. Determine the Capacity/Gallons of fluid you need to contain. (A berm with a 1' wall will contain 7.48 gals/sq ft. Don't forget to allow for displacement of the object you are trying to contain). Allowing 110% containment is usually sufficient.
Example: I have a 3000 gallon tanker truck to contain that measures 36' long by 8' wide.
1.) L + 4 x W + 4 = total square feet of berm
2.) 36 + 4 x 8 + 4 = total square feet of berm
3.) 40' long x 12' wide = 480 square feet
4.) 480 square feet x 7.48 gals/sqft = 3,590 gallon capacity (Note: the capacity is more than sufficient to contain my 3000 gallon tanker truck and allow for displacement)
I WOULD PLACE MY ORDER FOR A: 12' WIDE X 40' LONG X 1' TALL BERM
