2 BY KEYSTONE The chice t build green has revlutinized the cnstructin industry. Chsing prducts and prcesses with a lwer impact n the envirnment nt nly increases efficiency; but, als guides design decisins tward envirnmentally sustainable practices. As mre peple think green, the prducts and prcesses that supprt the green initiative have becme the new standard in building guidelines. As the wrldwide innvatin leader in the segmental retaining wall (SRW) industry, Keystne Retaining Wall Systems LLC cntinues t set the standard fr excellence. As an envirnmentally cnscius cmpany, Keystne is cmmitted t ffering a wide range f site slutins that respnd t green building and cnstructin needs. Many f ur slutins cntribute tward qualifying yur prject fr credits under the U.S. Green Building Cuncil s Leadership in Energy and Envirnmental Design (LEED) prgram r similar green cnstructin prgrams. In additin, Keystne s prducts are ften made f recycled materials and ffer a durable, lng-lasting slutin helping t reduce the impact n ur envirnment.

3 Natural and Recycled Materials Cncrete is an envirnmentally friendly building prduct cmpsed f bth natural and recycled materials. Amng thse recycled materials are cncrete aggregate, fly ash and irn xide. During the manufacturing prcess, waste cncrete is ften prduced. T reduce the amunt f waste destined fr landfills, mst manufacturers crush this cncrete int aggregate and reuse it. Fly ash, a waste material prduced and then discarded by cal burning plants, is anther cmpnent used t manufacture cncrete retaining wall units. SRW units use synthetic irn xide, made by burning recycled scarp steel at high temperatures, t clr the units. The natural and recycled materials used in the manufacturing prcess result in an envirnmentally cnscius and efficient cnstructin prduct. Water Sand Recycled Cncrete Fly Ash 3

4 Ersin Preventin Sil ersin is a serius envirnmental threat and a majr cntributr t the degradatin f water quality. Wind, rain and water runff displace sil particles frm bare r sparsely cvered earth reducing the stability f the riginal site resulting in impaired perfrmance f dwnstream drainage systems. In many instances, SRWs are cst-effective slutins t sil ersin. Keystne prducts are ften used in cnservatin effrts alng channels and waterways, near steep earthen slpes and ther critical applicatins. When taller wall heights are required, gegrid reinfrcement may be an apprpriate slutin and can be added t a wall design. The result is a lng-term, ecnmical slutin that minimizes r eliminates sil ersin. 4

5 Recycled Durability Cncrete SRW units ffer a lng-lasting retaining wall slutin fr bth structural and landscaping prjects. As a durable building material, cncrete s lifespan surpasses that f alternatives such as timber r railrad ties. Cncrete units resist weathering actin, chemical attack and abrasin while maintaining the desired engineering prperties. Nt nly are SRW units made frm recycled materials, units can als be recycled. When a SRW is n lnger needed, r desired, the units can simply be remved frm the site and repsitined elsewhere r crushed and recycled int new units. 5

6 Prmtes Vegetatin Keystne units ffer an innvative planting system that can prduce a lush blanket f irrigated vegetatin. The unique cavity f Keystne s plantable unit is perfect fr plants up t ne galln in size. This prduct als allws fr the placement f irrigatin systems and prvides the natural drainage that encurages plant rt grwth allwing the wall structure t spring t life. With the ability t supprt rich plant life, Keystne plantable units bring a degree f depth and clr previusly unavailable in a structural wall prduct. 6

7 LEED Credits The U.S. Green Building Cuncil s LEED prgram wrks fr all building cnstructin frm hmes t crprate headquarters at all phases f develpment. Prjects pursuing LEED certificatin earn pints acrss several areas that address sustainability issues. Based n the number f pints achieved, a prject will receive ne f fur LEED rating levels: Certified, Silver, Gld, r Platinum. The chart belw shws ptential LEED credits available in the categry BD+C: New Cnstructin and Majr Renvatins (v4) when using Keystne retaining wall systems. Actual credits earned will vary by prject and prduct manufacturer.
