Polyurea wastewater lining and secondary containment: applicator spraying a grey liner on the walls of a bund around storage tanks

Polyurea Wastewater Lining: Treatment Plants, Lifting Stations and Containment

Avatar for TargetTarget
Polyurea wastewater lining is a hot-sprayed membrane that protects concrete in sewage and treatment structures. Egypt keeps building new treatment plants and lifting stations as its cities grow. In these structures, bare concrete faces water, salts, gases and acids every day. This guide explains what the Krypton datasheet reports, how to prepare damp concrete, and how to handle joints. It ... Read More

Polyurea Pond Lining for Lakes and Irrigation Basins in Egypt

Avatar for TargetTarget
Polyurea pond lining means spraying a hot, two-component membrane onto the bed and banks of a pond, lake or basin. In Egypt, many compounds use artificial lakes as their main landscape feature. At the same time, farms store water in concrete or earth basins. Both lose water, and money, through leaks. This guide explains where polyurea fits, how concrete and ... Read More

Podium Waterproofing Polyurea: A Guide to Podium Decks and Planted Roofs

Avatar for TargetTarget
Podium waterproofing polyurea systems protect the decks that sit over basements, car parks and malls. Many podiums in Egypt’s new cities also carry gardens, paving and planters. Once these layers go on, the membrane is buried and hard to reach. So the choices made before the soil arrives decide how the deck performs for years. This guide covers the risks, ... Read More

Polyurea Primer: Preparing Concrete Before Spraying

Avatar for TargetTarget
A polyurea primer is the thin coat that goes between the concrete and the polyurea membrane. It seals the pores, binds loose dust and gives the membrane a firm grip. In fact, many lining problems start below the membrane, not in it. This guide shows how to check the concrete, how to choose a primer and how to prepare the ... Read More
