Product catalog summary
Introduction
The document by Gruppo Ceramiche Gresmalt SPA provides an overview of porcelain stoneware slabs, focusing on their specifications, applications, and benefits for outdoor paving. It emphasizes the innovative solutions offered by 20 mm thick slabs for various outdoor settings.
Specifications
The porcelain stoneware slabs are 20 mm thick, designed for durability and versatility in outdoor environments such as gardens, patios, driveways, and beaches. They are stain-resistant, easy to clean, non-slip, and wear-resistant, maintaining their appearance over time and withstanding various weather conditions.
Installation Procedures
The document outlines several installation methods, including dry laying, adhesive bonding on screed, laying on grass, gravel, sand, and raised installation on modular supports. Each method is tailored to specific environmental needs and allows for easy repositioning.
Performance Standards
The slabs are described as resistant to thermal shock, frost-proof, and suitable for pedestrian areas due to their high friction coefficient. They are also hard and compact, making them ideal for both pedestrian and vehicular traffic.
Applications
The slabs are suitable for a wide range of outdoor applications, including private gardens, public parks, courtyards, terraces, balconies, outdoor seating areas, holiday villages, swimming pools, squares, and pathways.
Key Features
  • Stain Resistance: Compact and impermeable to common staining agents.
  • Ease of Cleaning: Dirt does not penetrate the surface, allowing for effective cleaning.
  • Thermal Shock Resistance: Frost-proof and resistant to extreme temperatures.
  • Non-Slip Surface: High friction coefficient suitable for pedestrian areas.
  • Wear Resistance: Hard and compact surfaces withstand traffic.
  • Indoor-Outdoor Coordination: Seamless transition between indoor and outdoor spaces.
Conclusion
The document concludes by highlighting the versatility and high performance of the Twenty porcelain stoneware slabs, making them an excellent choice for modern outdoor paving needs due to their durability, ease of installation, and maintenance.
Tile Specifications and Collections
The document details various porcelain tiles with colored bodies, available in different sizes and finishes. Tiles are categorized by color and collection, with specific details on dimensions, surface finishes, and packaging. Collections include Blue Light, Dublin Stone, EcoProject, Slate, Stratos, Tracks, Valsusa, Timber, Atelier, and Evoque, each offering unique color options and sizes.
Special Pieces and Installation Recommendations
Special pieces are available for each collection to complement the main tiles. The document recommends a laying pattern and joint width of 6 mm for optimal installation, with kits consisting of specific pack sizes to facilitate the process.
Evoque and Poseidon Series
The document provides detailed information on the Evoque and Poseidon series, focusing on their multi-size modules, specifications, and recommended installation procedures. Both series are available in various colors and sold as kits that cannot be separated.
Installation Instructions
Guidance is provided for laying tiles on gravel, sand, or soil without requiring professional skills. Key considerations include assessing the intended use, climatic conditions, and types of dynamic loads. Recommended tools include excavation tools, a spirit level, a rubber mallet, and gravel for the finishing layer.
Specifications and Requirements
The document outlines procedures for laying paving slabs on surfaces such as gravel, sand, soil, and grass, emphasizing that no specific professional skills are required. Key requirements include excavation tools, a spirit level, a rubber mallet, and materials like coarse sand, gravel, and a geo-textile membrane for certain installations.
Procedures and Recommendations
The installation process involves preparing the sub-base, laying the slabs, and stabilizing them. Recommendations include assessing the intended use, expected loads, and climatic conditions, especially in exposed areas. Dry laying is suitable for areas with low static and dynamic stress.
Specifications and Procedures for Ceramic Slabs
The document outlines procedures for installing ceramic slabs, focusing on ensuring adequate load-bearing capacity of the sub-base and screed. It advises against dry installation techniques for large areas subject to vehicular traffic, recommending adhesive installation on reinforced concrete screeds instead.
Preliminary and Preparatory Tasks
The designer or site engineer is responsible for ensuring all necessary works and checks are conducted to guarantee the sub-base and screed's load-bearing capacity, including excavation, soil compaction, and placement of aggregate layers.
Installation on Screed
The process involves creating a reinforced concrete bed, installing a separation membrane, and laying the ceramic paving with appropriate slopes and expansion joints. Adhesive should be applied using a double buttering technique, and slabs should be laid with a minimum joint of 5 mm.
Raised Floor Installation for Exterior Locations
Dry laying on supports offers advantages such as quick installation and easy inspection of underlying voids. It improves thermal comfort and reduces load on the underlying floor slab. Performance requirements and intended use should be carefully considered, and professional advice is recommended for elevated terraces.
Overview of Raised Flooring Systems
The document discusses the installation of raised flooring systems, focusing on dry installation methods for terraces. It highlights the benefits, technical requirements, and procedures for ensuring effective installation.
Benefits of Dry Installation
Dry installation on terraces improves thermal comfort in the underlying spaces and reduces the load on the supporting structure compared to traditional adhesive methods.
Pre-Installation Considerations
It is crucial to assess the performance requirements and intended use of the area, comparing them with the characteristics of the chosen ceramic tiles and supports. Consulting a qualified technician is recommended for elevated terraces.
Types of Supports
Supports are made from polypropylene or galvanized steel and come in fixed, adjustable, and self-leveling models. The choice of support type should consider the sub-base condition, slab type, and design load values.
Laying Surface Characteristics
The surface must be solid and capable of withstanding concentrated loads. A concrete screed of adequate thickness is necessary, and the surface must be waterproofed with a bitumen membrane with a minimum slope of 1.5% for water drainage.
Installation Guidelines
The installation area should be confined by walls or vertical supports to prevent lateral movement. After installation, the void beneath the floor can be inspected by lifting the slabs. Damaged slabs must be replaced immediately to maintain load-bearing capacity.
Technical Characteristics
The document outlines the technical standards and requirements for porcelain tiles, including water absorption, breaking strength, bending strength, deep abrasion resistance, thermal shock resistance, and frost resistance, all conforming to ISO standards.
