111. Introduction1.1 GeneralRoki Road Tunnel, Republic ofNorth Ossetia–AlaniaTunnel WaterproofingArea 40,000 m2LOGICBASE V–SL 1.5 mm2015This instruction manual was developed to be used at constructionsites when waterproofing underground structures of buildings andfacilitiesThis manual includes recommendations from TechnoNICOL forinstalling LOGICBASE V-SL PVC membrane. It is based on membranelaying technology and only contains general rules for installing waterprooofing, so should be considered as a short reference book.TechnoNICOL LOGICBASE V-SL membranes are produced ona state-of-the-art AMUT line (Italy) from high-quality raw materials(PVC, plasticizer and specialized additives) using the extrusionmethod.LOGICBASE V-SL membranes fully meet a number of requirements for strength, fire safety and resistance to external impacts(chemical aggressiveness of groundwater, other types of aggression and impact of microorganisms) and durability, and emit notoxic substances during construction and use of facilities.The membranes have all the necessary certificates required bylaw confirming their high quality.1.2 Designations and ScopeDesignationLOGICBASE V-SL waterproofing PVC membranes are produced inrolls with a standard width of 2.05 m, length of 20 m and thicknessof 1.5 and 2.0 mm. Rolls may be custom-made with a length up to35 m and thickness of up to 3.0 mm.The designation of membranes includes:—— material name—— V-SL index—— thickness in millimeters—— number of the company standard for material productionAn example of marking of a 1.5 mm-thick LOGICBASE water proofing PVC membrane:Museum Complex of the StateTretyakov Gallery, MoscowBasement WaterproofingArea 10,000 m2LOGICBASE V–SL 2.0 mm2015LOGICBASE V–SL 1.5 mm STO 72746455-3.4.3-201512341 Material name2 The V-SL index partially describes the base and specifications: V — polyvinylchloride (PVC); S — signal; L — layer3 Material thickness in millimeters4 Regulatory document reference number for production of the material.Designations and Scope7introduction

11Field of applicationLOGICBASE V–SL Waterproofing PVC Membranes are used for:—— rotecting bearing and retaining structures that are in contactwith soil against the impact of ground and surface water, including water under pressure;—— waterproofing underground structures, underground parkinglots, basements and other underground parts of civil construction facilities;—— waterproofing underground pedestrian crossings;—— waterproofing subway stations;—— waterproofing road and railway tunnels constructed by anymethod, including the trenchless method;—— waterproofing underground tanks.1.3 Specifications of LOGICBASE V–SLMembranesLOGICBASE V–SL waterproofing PVC membrane is a homogeneous, watertight sheet folded into rolls.The membranes have high performance parameters essentialfor waterproofing of both small low-risk structures constructed insimple geological conditions and highly critical buildings and facilities in complex geological conditions.The use of LOGICBASE V–SL membranes for underground waterproofing is based on the following properties:—— absolute water-tightness at water pressure of up to 1.0 MPa;—— tensile strength over 16 MPa;—— ability to stretch by over 400 % without loss of water-tightness;—— resistance to rupture by a nail over 150 N;—— cold-bending at -35 С max;The material is classified as a thermoplastic polymer, membranesheets are easily welded with hot air, without using an open flame.Welded seams have a high tensile strength and are absolutelywatertight.Advantages of LOGICBASE V–SL Membranes—— High durability;—— High resistance to mechanical impact;—— High strength and flexibility;—— High elasticity at low temperatures;—— Possibility of use in aggressive or acidic environment;—— Resistance to root penetration;—— Microbiological stability;—— High chemical resistance;—— Possibility of laying on a damp underground structure;—— High speed installation;introduction8Specifications of LOGICBASEV–SL membranes—— Loose laying without gluing to the base, which allows easy compensation of movements and deformations of structures and soildue to the strength and elasticity of the membrane;—— Possibility of instrumental quality control of performed work;—— Easy quality control of complete waterproofing.1.4 Marking, Rules of Membrane Storageand TransportationLOGICBASE V–SL PVC membranes are supplied on wooden pallets; rolls are stockpiled on pallets in three rows with one roll shiftin each row.Rolls are additionally wound with a polyethylene film andbound on a pallet with a polymer strip with lining.Each roll is packed in a non-transparent polyethylene film forprotection against contamination and UV light.Each pallet with products has a properly marked packing list.The marking contains the following information:—— manufacturer’s name and address;—— trademark;—— product name;—— designation of the polymer membrane;—— number of the company standard;—— product issue date;—— type of upper and lower surfaces;—— color of upper and lower surfaces.The rolls shall be stored horizontally in one tier in height on palletsor without pallets, at least 1 m away from any heating appliances.Membranes at the construction site shall be protected againstan impact of direct sunlight, rain, snow, ice, etc. If stored in dry,clean and moderately cold conditions, preparation for welding isminimized.IMPORTANT! DO NOT store pallets with membrane on surfaces with a slope greater than 3%.Rolls of material shall be transported in covered vehicles andstacked horizontally on pallets in no more than two rows.Other means of transportation that ensure the integrity of thematerial are possible with the customer‘s approval.Material shall be loaded and transported in accordance withthe Cargo Transportation Rules applicable to the means of transport used.Marking, Rules of Membranes Storageand Transportation9introduction

PVC disk fixing elementintroduCtion1PVC membranes shall be covered with geotextile before layingthem on concrete surfaces to prevent any possible damage.If the removal of water, coming through the retaining wall isrequired, a Planter Geo dimpled membrane should be placedbetween the diaphragm wall and the waterproofing system.The waterproofing is compartmentalized into isolated sectionsto monitor its integrity and to enable its repair.compartmentalization of waterproofingThe PVC membrane waterproofing system is loose-laid, i.e. it isnot attached to a base. In theevent of damage to the waterproofing, it can be compartmentalized into isolated sections toavoid water spreading alongthe entire structure. ProfiledPVC strips, waterstops, are usedfor compartmentalization.One of the waterstop surfaces has anchor elements along its entirelength. Waterstops are welded using hot air, with the smooth sidefacing towards the waterproofing membrane, thereby forming closedrectangular outlines. The maximum recommended size of one sectionis 150 m2. Waterstop anchors are embedded in concrete duringconcrete casting.Having such a system means that if waterproofing is damaged, water penetrating under the membrane does not spreadalong the whole structure, but is confined to a section bounded bywaterstops.The design includes a repair injection system to eliminatea leak in the TN-FOUNDATION–Diaphragm Wall waterproofingsystem.10.

Waterproofed section bounded by waterstops121310116914The Injection SystemThe injection system servesboth for monitoring ofthe waterproofing conditionand for its repair. The injectionsystem consists of injectionflanges and injection hosesconnected to them by fittings.Each standard section has5 injection flanges installed –4 in the corners and 1 in the center. When calculating the numberof injection flanges, use the following recommendation: 1 flangefor a maximum area of 30 m2, at least 2 flanges per 1 section.The flange is spot-welded to membrane. Injection hoses areconnected to flanges and routed through the reinforcement cageinside the structure directly or get collected in special injectionniches. Each hose is marked according to the section it relates to.If waterproofing is damaged and a leak appears, water normally starts coming through the injection hose, which allows preciselydefining the damaged section.After the damaged section is identified, special injection polymer compounds are pumped through the injection system in liquidform and fill the damaged section by filling the space between thewaterproofing membrane and the structure, and then are polymerized forming a dense watertight gel. In this way, water-tightness ofthe waterproofing system is restored.introduction12Description of a Waterproofing SystemBased on the LOGICBASE V-SL PVC Membrane157841. Soil2.

111.6 General Guidelines—— Always follow the procedures specified in this guidebook;—— Carefully plan the procedure for installation of LOGICBASE V–SLwaterproofing membranes;—— Always consider the weather conditions at the construction site,both current and future;—— Clearly define the scope of work for the current day;—— It is desirable to have a completed section of waterproofing covered by protective layers by the end of a working day, includinggeotextile, polyethylene film and a protective screed. If a protective screed cannot be installed on the same day, it is preferableto leave the membrane unprotected, but fence off the completed work section and not admit any unauthorized persons toit. Before resuming the work, carefully check the unprotectedsection for any membrane damage;—— Seam quality control needs special attention;—— Before commencement of work, perform trial welding on site todetermine optimum welding modes for specific weather conditions;—— All seams made using automatic equipment with formation of adouble seam should be checked instrumentally using the overpressure method (see Section 4);—— Seams made with manual equipment should be spot checked bythe destructive method (see Section 4);—— Carefully check for possible mechanical damage of the laidmembrane (through punctures, cuts, ruptures).IMPORTANT! Preparation for WorkBefore starting waterproofing work, the LOGICBASE V-SLmembrane shall undergo incoming control that consistsin checking for compliance of the material’s quality with regulatory documents and the data sheet.1.7 SafetyDuring waterproofing work using polymer membranes, adhere tothe following requirements:—— Materials and equipment must be stored in areas designatedin the project execution plan.—— The following is prohibited during the work:use of faulty equipment and working without personal protection equipment;allowing unauthorized individuals to perform work;waterproofing works at wind speeds over 15 m/s, in case oficing, rain, snowfall or fog, affecting visibility in the work areaand at ambient air temperatures below –10 С or above 45 С.—— The waterproofing site must be provided with fire extinguishers,a sand box and fire-fighting equipment;introduction14Safety—— Waterproofing should be performed by trained personnel, whohave passed an exam for minimum technical requirements forwaterproofing, using PVC membranes and work safety;—— Welding must be performed by skilled workers with experienceof working with welding machines, including those manufacturedby Leister;—— Before commencement of work, the workers must be familiarized with the project execution plan and safety rules. Workmanagement and quality control must be performed by personswith experience in waterproofing of underground structures;—— Workers must be provided with work clothes, work shoes andpersonal protection equipment;—— Put on your goggles when using liquid detergents and compounds for seam surface preparation. These recommendationsmust be observed before welding of membranes and waterstopsas well as disc fixing elements;—— Welding equipment can be connected only to an earthed electrical outlet. An extension cable with protective ground may beused. When operating the equipment, use a circuit breaker withdifferential protection for safety;—— In order to ensure a continuous and stable welding process, it isrecommended to connect the welding machine to a separatenetwork or use a separate 220/380 V generator set;—— Do not change nozzles when the heating element is on, especially using tools (pliers). In case of incorrect clamping, this willcause nozzle deformation and, consequently, a poor qualityseam, even if work is performed correctly;—— Upon completion of the work and during replacement or cleaning of nozzles, keep the machine turned on for at least 5 minutes with the heating element deactivated in order to avoid itsoverheating;—— Do not operate electrical equipment if the power cable is damaged or reeled. Always completely unroll the reel before startingthe work.—— Upon completion of work with electrical equipment, disconnectthe power supply points from power sources and remove themto a closed room or cover with watertight material;—— Tools must be removed upon completion of ea
