Mapeproof AL AP system

Waterproof protection for foundations

Long-term protection

Over the last several decades, economic growth and the development of infrastructures has witnessed a high tendency to concentrate human activities into large metropolitan and suburban areas. This has led to an increasingly intense use of the spaces available.

The enormous progress in technology and construction methods has also enabled large underground areas of cities to be used more rationally and more intensively. Underground sections of buildings are often immersed in groundwater, sitting in damp ground or in contact with different types of soil or rocky ground: conditions that raise new problems in terms of design and durability of materials.

Mapei approaches these new construction challenges by means of a protection system for underground structures that safeguards against all the potential risks and hazards such as water, moisture, gas and contaminants contained in rock and soil.

This waterproofing system is designed to maintain its technical characteristics and performance properties over time, thereby significantly contributing to the durability of foundations.

Mapei Research and Development laboratories have developed Mapeproof AL AP: a complete system of HDPE waterproofing membranes. These membranes form a continuous bond (fully bonded) with the concrete substrate and can be installed simply and quickly.

Mapeproof AL AP is the evolution of pre-cast systems characterised by its extremely simple application, with proven strength and durability and guaranteed levels of protection, safety and reliability over time. Mapeproof AL AP is yet another example of how, day after day, Mapei is constantly committed to product and industrial process innovation with the aim of supplying unique technologies that enable construction work all around the world to evolve and become more simple.

Composition of a Mapeproof AL AP membrane

Mapeproof AL AP is a waterproofing membrane consisting of a tough synthetic HDPE sheet, with an adhesive side covered by a pressure-sensitive protective coating; when it comes into contact with concrete, it guarantees a tough, strong bond with the placed concrete itself (fully bonded). This composition guarantees that, when the sheet comes into contact with the placed concrete, the membrane forms a tough bond with the placed concrete.
