Dampcoursing’s structural waterproofing system (commonly known as ‘tanking’) is a highly effective waterproof treatment process for sound stable surfaces normally encountered within building structures.

The slurry used is a pre-mixed formulation of plastic modified hydraulically setting powder. When mixed with water and applied to a masonry substrate, silicate salts form at the interacting faces which enter and fill the pores and capillaries of the substrate and form a monolithic bond to block the passage of water as well as becoming an integral part of the structure.

The Dampcoursing range is complemented by ancillary products to form a total system which is suitable for use in a wide range of circumstances encountered in commercial and domestic properties old and new. It may be applied on either the positive or negative side and has the ability to bridge hairline cracks, is non toxic, non corrosive and is unaffected by ultra violet light.

Dampcoursing carries out a full site survey, and recommends the course of treatment based on this.

Structural waterproofing falls into two categories - a complete system or a partial system.

Whatever the system, success is totally dependent upon the preparation of the substrate onto which the system will be applied.

Work will almost certainly necessitate cleaning of the substrate, and Dampcoursing calls upon specialist companies such as Blastit Ltd. to carry out this work.

Blasting creates a finished etch to the surface which is guaranteed to be suitable for this purpose. This excellent key is created without vibration or damage to the substrate, and the wet blasting also greatly reduces the amount of dust generated.
