Thermoplastic Waterstops

Product catalog summary
Introduction
This document provides technical specifications and guidelines for thermoplastic waterstops by LESCHUPLAST GLT, part of the Besagroup, designed to seal construction joints in concrete structures against water ingress.
Specifications and Standards
Waterstops must comply with German standards DIN 18541 or DIN 7865, or be part of waterproofing systems with a general construction supervision certificate (AbP). Two material qualities are outlined: LECOTRIL DIN 18541, compatible with bitumen, and PVC-P, which is not.
Material Properties
LECOTRIL DIN 18541 waterstops have an elongation at break of 350% and a tensile strength of 10 MPa. PVC-P waterstops have an elongation at break of 275% and a tensile strength of 8 MPa.
Product Range
The document lists various waterstop types, including combination construction joint waterstops (KAB), internal and external construction joint waterstops, and expansion joint waterstops, each designed for specific applications and conditions.
Installation Guidelines
Instructions are provided for installing different waterstop types, emphasizing proper placement and concrete compression. Storage instructions highlight keeping swelling rubber dry to prevent premature activation.
Application Instructions
Detailed installation instructions are provided for various scenarios, such as floor/wall and wall/ceiling applications, including methods for connecting joints using terminal strips and welding techniques.
Additional Features
Information on joint tubes for controlling shrinkage cracks and sealing construction joints in watertight concrete walls is included, highlighting their quick and efficient installation and proven performance.
Conclusion
The document offers comprehensive technical details and practical guidance for selecting, installing, and using thermoplastic waterstops in construction projects to ensure effective sealing and protection against water ingress.
Specifications and Storage
Joint widths should not exceed 10 mm. Waterstops must be carefully unloaded, stored on wooden pallets, and protected from contamination and damage. They should be stored in hot rooms before processing to avoid deformations.
Installation Procedures
Waterstops must be installed without deformations, creases, or warping, symmetrically aligned with joint axes, and securely fastened to prevent displacement during concreting.
Concreting and Formwork
Before concreting, waterstops must be cleaned and fully embedded without cavities. Care must be taken to avoid damage during concrete compression. External compactors may be used for external waterstops.
Standards and Recommendations
The document refers to DIN 18197 for planning and installation standards, emphasizing that the information is based on research and practical experience but does not cover specific application work.
Technical Information
All dimensions are in millimeters, with tolerances according to DIN 16941. A cross-section diagram of a multifloor building with various waterstop types and related products is included.
