• Damp proof course (dpc) in masonry
• Sealing of foundation pits

Properties

• Polyurethan-based combi injection resin
• Fast curing with and without water
• Fast sealing foam structure upon contact with water (pressing water)
• Low viscosity
• Elastic foam structure
• Fast curing – permanent sealing
• Adjustable reaction time (accelerator WEBAC_® B15)
• Also suitable for use at low temperatures

Application

• Injection by 1C or 2C pump

PU combi injection resin WEBAC_® 1500 for fast and permanent sealing processes

The hybrid resin WEBAC_® 1500 quickly forms a dense foam upon water contact which provides for a permanent sealing effect. WEBAC_® 1500 combines the positive properties of polyurethane foam resins and polyurethane resins and is therefore also referred to as hybrid resin. 
 

Hybrid resin WEBAC_® 1500: the product's expansion depends on the water content

The hybrid resin WEBAC_® 1500 is injected until resin emerges from the masonry and an even material distribution has thus been obtained. The temperature of the material and the structural elements influence the reaction time of the hybrid resin during the injection. WEBAC_® 1500 should always be applied at temperatures above 5 °C. The water content determines the degree of expansion: at 5 % water content (and 21 °C) the material expands its volume by 12 times and by 10 times at 10 % water content.
