DuraPlate 100 Corrosion Resistant Liner - A-LOK

1 DURA PLATE 100 LINERCORROSION Resistant SYSTEMPart 1. The Dura Plate 100 LinerSystemThe objective of this specification is tocover the supply and installation of a vac-uum formed semi-rigid Liner for use inwastewater and light industrial concretestructures to effectively shield the interiorof the structure from Corrosion . The design of the Liner system shall insurethat it will conform to the contour of thestructure and form a permanent mechani-cal bond to the concrete through use ofpreformed horizontal ribs and Liner will be formed in such a mannerthat the joints between the structure sec-tions will be afforded protection throughthe use of a continuous PVC return intothe joint for a minimum of.

2 50 of an will be made to allow the pipepenetrations to be sealed by applying acementitious Corrosion Resistant materialto the unlined exposed areas within 2. shall be Dura Plate 100as manufactured by A-LOK Products,Incorporated, Tullytown, Pennsylvania. Composition - The Liner ,channel joints, H-joints and corner jointsshall be manufactured from an AcrylicPVC sheet compound will resultin a semi-rigid material suitable for ther-moforming to the contour of the structure and shall maintain a minimum wall thick-ness of .065 inches. Joint Composition -The fabricated Liner panels shall be joinedtogether by a slotted strip of EPDM rub-ber according to the manufacturer s spec-ification as illustrated in Figure 1A - Panel Joint Butyl Joint Composition -Sections of lined concrete structures shallbe joined together by an approved butylstrip ( A-LOK Products, Inc.)

7 Part 4. Details and Dimensions of Standard Liner panels shall have a min-imum thickness of .065 inches. A combi-nation of standing ribs and mechanicaldovetails shall be used to secure the linerpanels to the wall of the structure andshall be spaced a maximum of Liner panels with a combina-tion of standing ribs and dovetails indiameters of 48" through 60" shall be atleast .50 inches high. Panels of 72" diam-eter and above shall be at least .75 Liner with locking extensionsshall be able to withstand a test pull of 100pounds per linear inch applied perpendi-cular to the concrete surface for a periodof 60 seconds.

8 No rupture of the lockingextensions or withdrawal from embed-ment shall be acceptable. This test shall bemade at a temperature between 70 and 80degrees Fahrenheit Liner panels shall be formed tothe correct radius to assure a true diametermatch between joined precast sectionswhen Liner panels shall be formedwith a continuous return into the joint fora minimum of .50 of a inch which shallafford protection between the lined pre-cast All radius panels shall be vac-uum tested for pinholes during the mold-ing process and shall withstand a mini-mum of 25 inches of mercury for a periodof 60 Panel sections shall be customformed to a specified height not to exceed6' in overall length.

9 Lengths specifiedshall include a tolerance ratio of +/- .0625per 5. Plant Installation of General - Installation of all lin-ing shall be done in accordance with themanufacturer s Lining coverage shall not beless than the minimum shown on theapproved shop drawings or The Liner panels when assem-bled shall form a circular cylinder that fitssnugly against the inner steel core of theform. A removable extruded rubber pro-file or suitable one-sided tape can be usedto seal the Liner against the core to preventconcrete fines from washing downbetween the Liner and steel Concrete poured around theliner shall be distributed evenly to preventshifting of the Concrete poured against theliner shall be vibrated, or compacted in amanner to protect the Liner and produce adense homogenous concrete to securelyanchor the assembly to the exposed sur-faces on the interior of the When extracting the steel core,care should be taken to protect the linerfrom damage.

10 Instruments with sharp orjagged edges should not be used to releasethe forms from the Visual inspection of the linershall be made after demolding and anycuts or tears shall be repaired by follow-ing the manufacturer s repair The concrete producer shalltake all necessary measures to preventdamage due to casting, demolding, anddelivery of the lined concrete 6. Field Installation of General - Field installation ofall lined precast sections shall be done inaccordance with the recommendations ofthe The horizontal joints betweensections of lined concrete structures canbe made by either butyl or a combinationof butyl and rubber joint per the recom-mendation of the concrete manufacturer.
