HYPERDESMO®-300

HYPERDESMO® -300 is a single component, moisture curing polyurethane/polyurea liquid applied membrane which has been certified for bridge deck waterproofing according to ETAG 033 with excellent chemical resistance and mechanical properties, very high abrasion resistance, specially designed for difficult and demanding waterproofing applications. HYPERDESMO® -300 displays crack bridging properties over a wide range of extremely high or low temperatures. Due to its thixotropic properties, it is easily applied on sloped and vertical substrates without any sagging.
Bridge deck waterproofing,
waterproofing of swimming pools (under tiles),
Chemical-treatment tanks and roofs with high traffic.
SURFACE PREPARATION

The substrate should be clean, dry and dust free. Vacuum treatment or high pressure washing is recommended to remove dust. The waterproofing liquid membrane should be applied atleast 28 days old concrete or other cementitious substrate. The primer application can be done over the damp concrete surface also. But any ponding water should be removed before the primer application

APPLICATION OF PRIMER

Geodesmo 50 can be applied with brush, roller or airless spraying on concrete, subject to substrate porosity. It has a very fast curing profile, which allows it to be used more successfully in colder climates and when rain is not very predictable. The main liquid membrane can be applied after 2-3 hours of primer application

CRACK REPAIR AND JOINT FILLING

Inner angles and small cracks should be treated with Hyperseal®-Expert-150 polyurethane based sealant or Hyperseal®-25 LM-S. In case, there are any spots on the concrete surface that need repair, filling or smoothing like large cracks & cavities, Hygrosmart Fibre or Epoxy resin-21T is used with potential incorporation of silica sand.

APPLICATION OF WATERPROOFING MEMBRANE

HYPERDESMO® -300 is applied in one or two successive coats by using roller or spray. The product has certified according to ETAG 033 that holds a CE mark with an assumed intended working life of 25 years. Due to its thixotropic properties, it is easily applied on slope as well as vertical substrates without sagging.
