A portable drip containment device comprises a tray formed of fuel and chemical resistant fabric. Side walls of the tray are supported by removable bolster segments formed of resilient open cell foam members enclosed within sleeves. The bolster segments are wrapped within a flap of material extending from under the side wall of the tray and around the bolster segments to secure them to the side walls. The outer edge or end of the flap is secured to the side wall. The bolstered side walls may be repeatedly driven across by industrial vehicles without harming the bolster or side wall. The modular bolster segments may be removed and easily stacked, and the tray folded and rolled into a compact modular form, for transport, storage, and reuse of the portable containment tray.

A method for removably securing deformable bolster segments adjacent upward-extending side walls of a drip containment tray, comprising the steps of: forming a deformable bolster segment from a resilient synthetic foam;placing said deformable bolster segment adjacent an upward-extending side wall

1. A method for removably securing deformable bolster segments adjacent upward-extending side walls of a drip containment tray, comprising the steps of: forming a deformable bolster segment from a resilient synthetic foam;placing said deformable bolster segment adjacent an upward-extending side wall of the drip containment tray;wrapping at least one flap extending from the drip containment tray around the deformable bolster segment; andattaching the at least one flap to an upper edge of the adjacent side wall to enclose the deformable bolster segment and support the side wall. 2. The method of claim 1, wherein the step of forming comprises the step of: fashioning a bolster core from the synthetic foam wherein the bolster core has a cross section having four sides and at least one right angle. 3. The method of claim 1, wherein the step of placing comprises the step of: positioning the bolster segment adjacent the upward-extending side wall such that a right angle along one edge of the bolster segment is disposed proximate a lower edge of the upward extending side wall. 4. The method of claim 1, wherein the step of wrapping comprises the step of: providing at least one flap along each of the upward-extending side walls of the drip containment tray. 5. The method of claim 1, wherein the step of wrapping comprises the step of: providing a plurality of the at least one flap spaced at intervals around the perimeter of the drip containment tray. 6. The method of claim 1, wherein the step of attaching comprises the step of: attaching at least one portion of a fastening mechanism to the at least one flap and a second portion of the fastening mechanism to the upward-extending side wall; whereinthe fastening mechanism is selected from the group consisting of a hook and loop fastener, and a spring clip, a lace, a cord, and a combination thereof. 7. The method of claim 1, further comprising the step of: enclosing the deformable bolster segment within a sleeve formed of a chemically resistant fabric.
