InfinityTM Deck Installation Guide

1. Introduction

Thank you for choosing Eva-Last® decking. In these guidelines we aim to assist you in successfully completing an installation that will last as long as the Eva-Last® decking products themselves.

• ThepurposeofthisguideistohelpyouadheretoallEva-Last®warrantyspecificationsandcreateadurable, long-lasting installation. • Pleasenotethelimitationsofthisguide: o This guided intended only for Eva-Last® single level square decks. oThepersonusingtheseguidelinesshouldalreadyhaveabasicunderstandingofdeckbuildingpractices. oDecksmustbebuiltinaccordancewithfederalandlocalbi-lawsandbuildingcodes.

Please bear in mind that decks of varying shapes may require different calculations and techniques. Please do not hesitate to contact Eva-Last® should you need any technical assistance at any stage of your build.
