Drizoro - rychleschnoucí malta na bázi cementu Maxroad Express

A mixture of cement in properly selected aggregate and modifying agents. After mixing with water or mixing liquid, it forms an easy-to-apply, quick-setting cement mortar, which is characterized by high compressive strength.

Features

• good adhesion and quick bonding: the repaired area can be put into service as soon as 2 hours after application of the material at 20 C or after 1 hour at 30 C
• it can be used on damp surfaces
• breaks and disruptions in traffic caused by repairs do not exceed two hours
• resistance to freezing and thawing
• does not contain chloride
• easy to apply
• high quality and durability of the repairs performed
• high mechanical parameters

Application

• urgent repairs of floors and concrete substrates that require very quick re-commissioning, such as: airport runways, damaged as a result of wear or bombing, bridge plates, expressways, loading and unloading ramps, warehouses, parking spaces, garages, parking spaces, load-bearing capacity, access roads to the site, industrial floors, etc.
• after adding sand and aggregate up to 50% by weight as bonding material for large-volume repairs (up to 2 m)
• as a clean product for minor repairs and patching of concrete surfaces
