Abstract: Methods of manufacturing mats for use as support surfaces include mixing pre-used material with virgin material to form a blended material and forming the mat for use as a support surface from the blended material. Mats for use as support surfaces include a body having a composition of at least 30% by weight of pre-used material and the remainder being virgin material.

Abstract: Mats and methods of making the same are described. The mats include a main body defined by a plurality of sidewalls and two exterior surface walls opposing each other, a lip structure extending outwardly from the plurality of sidewalk around a portion of a periphery of the main body, and at least one fiber-reinforcement layer arranged between the two exterior surface walls of the mat. The methods include depositing a first deposition layer of material within a mold, positioning at least one fiber-reinforcement layer on the first deposition layer, depositing a second deposition layer of material within the mold over the at least one fiber-reinforcement layer and the first deposition layer, and treating the first deposition layer, the at least one fiber-reinforcement layer, and the second deposition layer to form a mat.

Abstract: Mats and panels of mats and methods of making the same are described. The panels include a first portion defined by a first material and a second portion defined by a second material. The first material and the second material have at least one of different compositions and different material properties. The methods include depositing a first material into a mold of a panel, depositing a second material into the mold of the panel after deposition of the first material, and applying at least one of pressure and heat to the mold of the panel to form a panel having the first material and the second material having at least one different compositions and different material properties.

Abstract: Mats having a body having a thickness defined between a first side and a second side, a lip extending from the body and having a thickness less than the thickness of the body, the lip having a plurality of ribs and a plurality of channels defined between adjacent ribs of the plurality of ribs, and a plurality of lip stiffeners arranged within the channels of the lip and defining a transverse rib extending in a direction perpendicular to a direction of the plurality of ribs.

Abstract: A mat comprising a first side and a second side opposite the first side is disclosed. The mat has a body with a thickness defined between the first side and the second side and a width defined between a first edge and a second edge. A plurality of fortifying members can be positioned between the first side and the second side extend within the body substantially vertically with respect to the width. A lip can extend from the body of the mat and have a first rib having a first rib thickness. A first channel portion can have a first channel thickness whereby the first rib thickness is greater than the first channel thickness.
