About ISOTEC OPL
Abdichtungstechnik OPL GmbH & Co. KG is a certified ISOTEC specialist company based in Saterland (Sedelsberg), specialising in the elimination of moisture and mould damage to buildings. Its service portfolio includes the subsequent horizontal damp-proof barrier using special paraffin, exterior and interior waterproofing of earth-contact building components, crack injection and flex-band systems for crack widths from 0.2 mm, basement and balcony remediation, restoration render, interior insulation with fully mineral capillary-active panels, climate panels as well as construction and building drying. Every order begins with a measured moisture analysis on site, on the basis of which an individual remediation concept is drawn up. Customers are private owners, property management companies and commercial partners in the Oldenburg, Vechta, Stuhr, Löningen, Ganderkesee, Cappeln and Diepholz region. As part of the ISOTEC Group with around 1,200 employees, 150 locations and over 100,000 remediated buildings, the company offers a 10-year warranty on most services.

Systems and Materials
Special paraffin
Injected into dried masonry for the horizontal damp-proof barrier and permanently stops capillary water transport.
Restoration render
Absorbs salts that damage buildings and allows moisture from the masonry to diffuse.
Fully mineral interior insulation panels
Capillary-active and diffusion-open, up to 10 cm thick, raising the wall surface temperature by up to 10 °C.
Climate panel
Raises the wall surface temperature and regulates the indoor climate through temporary moisture absorption.
Liquid plastic
Used in balcony remediation as a liquid-applied waterproofing system with surface protection.
Multi-layer waterproofing system
Large-area exterior waterproofing of earth-contact building components against laterally penetrating moisture.
Concrete
Material for crack injection, basement floor remediation and wall-slab connection.
