An absorption mat 1 receives organic hydrocarbons in liquid, paste-like or solid form, for example, oil, fats, fuels and solvents. The absorption mat includes a plate-like molded body 2 made of rubber granulate 3 or rubber shavings 3 bonded to each other to define a plate-like body. A base layer 6 resistant to the hydrocarbons is joined by vulcanization to the plate-like molded body 2. The base layer 6 is a composite base barrier layer including first and second layers (10, 12) made of hydrocarbon resistant material and a mesh-like support layer 14 is sandwiched and trapped between the first and second layers (10, 12) for preventing unwanted stretching of the mat during manufacture and when handling before placement on the ground or floor area and when in use.

[ What is claimed is:] [1.] An absorption mat for absorbing hydrocarbons in liquid, paste or solid form including oils, fats, fuels and solvents, the absorption mat being suitable for placement in a work area for use by personnel and the absorption mat comprising:a flat molded body having a plate configuration;said body having an uncovered top surface completely exposed to receive said hydrocarbons thereon and said body having a bottom surface;said body being defined by granulate or shavings made of elastomer for absorbing and trapping said hydrocarbons therein;binding means for joining said granulate or shavings in a form-maintaining rigid bond with each other and to define a multiplicity of hollow spaces in said body communicating with each other and said top surface thereby facilitating the dispersal of said hydrocarbons within said body for absorption thereby;said binding means being resistant to hydrocarbons thereby causing said body to retain its overall shape in the presence of said hydrocarbons;said flat molded body having additional spaces formed therein to accommodate swelling of said flat molded body as the hydrocarbons become trapped therein;a composite base barrier layer joined to said flat molded body at said bottom surface thereof; and,said composite base barrier layer including: first and second layers made of hydrocarbon resistant material and a mesh support layer sandwiched and trapped between said first and second layers for preventing unwanted stretching of said mat when handling before placement and when in use.
