Flooring panel or wall panel and use thereof

A panel designed to be interlocked with another similar panel, said panel comprising two pairs of parallel side edges, two of said side edges being provided with a locking means in the form of a groove and the other two of said side edges being provided with a locking means in the form of a tongue, each said tongue being adapted to be received in a groove of a similar panel;

• each said groove of said panel comprising at least one first snapping web formed on an upper side of said panel edge and each said groove further comprising at least one second snapping web formed on a lower side of said panel edge and each said groove further comprising a stabilizing groove portion remote from said panel edge;
• said stabilizing groove portion comprising substantially parallel walls;
• at least one of said first and said second snapping web defining a depression therein adapted to receive a protrusion on said tongue of a similar panel;
• each said tongue of said panel extending from said panel edge, each said tongue having distal and proximate ends, said proximate end being adjacent said panel and said distal end being remote therefrom;
• and at least one protrusion on said tongue intermediate said distal and proximate ends, said protrusion being adapted to be received by said depression defined by at least one of said first and second snapping webs of said similar panel and located intermediate said distal and proximate ends such that when said protrusion is interlocked with said depression on a similar panel, a stabilizing portion of said tongue extends beyond said interlocked protrusion so as to be received by said stabilizing groove portion on said similar panel, said stabilizing portion of said tongue comprising substantially parallel walls, whereby when said panel is interlocked with another similar panel both said tongue stabilizing portion and said at least one protrusion in said panel are fully received within said groove of said similar panel.
