Described herein are various examples of stackable interlocking support blocks formed of rigid foam, for forming single- and multi-course support systems for assembling hardscape raised patios and/or stairs, and stair and patio systems including such support systems.
Provided herein are various embodiments of molds, mold insert members, and methods, for mitigating malformation of interlocking retaining wall blocks, and retaining wall blocks produced thereby. In an embodiment, an insert member for a retaining wall block mold includes a convexly-arched front wall portion and a convexly-arched rear wall portion, for forming respective concavely-arched top side and bottom side portions of respective concrete retaining wall blocks. The concavely-arched portions resist malformation such as bulge and/or slump that may tend to occur between molding and curing of the concrete retaining wall blocks due to pressure within the block. The concavely-arched portions additionally provide respective concavities into which such malformations—should they occur despite being resisted by the concavely-arched portions—may be channeled, thereby to keep malformations within the intended envelope of the retaining wall block.
Provided herein are various embodiments of stackable interlocking support blocks formed of rigid foam, for forming multi-course support systems for assembling hardscape stairs, and stair systems including such multi-course support systems and multiple concrete step blocks and/or concrete landing blocks supported thereby.
Provided herein are various embodiments of retaining wall blocks suitable for use interchangeably as components in battered and vertical retaining wall construction. Each includes a block body and a vertical interlock system that includes: two female-type components comprising first and second grooves each extending along a bottom side of the block body and a male-type component extending across a top side of the block body. A lateral interlock system comprises a male-type lateral interlock interface integrated with a first side of the block body in lateral alignment with a female-type lateral interlock interface integrated with a second side of the block body. Methods for constructing retaining walls using the retaining wall blocks described herein are also provided.

In an embodiment, an insert member for a retaining wall block mold includes a convexly- arched front wall portion and a convexly-arched rear wall portion, for forming respective concavely- arched top side and bottom side portions of respective concrete retaining wall blocks. The concavely- arched portions resist malformation such as bulge and/or slump that may tend to occur between molding and curing of the concrete retaining wall blocks due to pressure within the block. The concavely-arched portions additionally provide respective concavities into which such malformations ~ should they occur despite being resisted by the concavely-arched portions - may be channeled, thereby to keep malformations within the intended envelope of the retaining wall block. 26 Date Regue/Date Received 2023-01-06
