An elastic gel includes a solid component and a liquid component. The solid component is a polyurethane polymer matrix. The liquid component is a plasticizer. The liquid component includes one or more vegetable oils or chemical derivatives of vegetable oils or a mixture thereof and is comprised in cells of the polyurethane polymer matrix.

A replaceable wear insert assembly for playing surfaces in pitching areas and other high-wear areas of baseball and softball fields and other playing fields. A recess member is permanently or semi-permanently installable in a selected area of the field, such as a pitching lane. The recess member accommodates a replaceable insert member having an upper surface with a layer of synthetic turf or track material, mounted to rigid panel. The insert member is removable from the recess member so as to replaceable when worn.

A floor pavement structure includes a top layer that seals the floor pavement structure and a PU gel layer. The PU gel layer includes a solid and a liquid component and is positioned between a base material and the top layer. The solid component is a polyurethane polymer matrix. The liquid component is a plasticizer.

A sub-irrigation system includes a special water distribution assembly that is able to rapidly disperse water underneath a court surface. The system has a water distribution assembly with a water channel and permeable fabric covering. The system also includes an electronic control system to monitor and maintain a desired moisture content of a court. Inevitable variations resulting from manual and gravity fed water control only are moderated or eliminated by the automatic control herein.
