Waterproofing Injection For Concrete To Know

MAPEGEL UTT SYSTEM

Three - component hydrophile gel for consolidating grounds and for creating barriers through injection in the concrete. As the leading waterproofing Injection for concrete in UAE, Mapei has the top-quality product you can choose from. Here are the details of our product.

DESCRIPTION

Flexible three-component hydrophilic gel with excellent adhesive properties for waterproofing by injection in underground structures. Specifically formulated to absorb shrinkage and expansion of cracks and voids generated by temperature variations.

WHERE TO USE

• Natural tunnels (traditional and mechanized tunnelling).
• Artificial tunnels (cut and cover).
• Underground constructions.

Application examples

• Waterproofing of loose and/or incoherent soil.
• Waterproofing of hydraulic structures with water leaks through macro-porosity and micro-cracks.
• Waterproofing of dam walls.
• Waterproofing of bulkheads.
• Waterproofing of tunnels.
• Repair of waterproofing systems (damaged or defective) by injection by means of re-injectable valves or pipes (repair of synthetic membranes and waterstops).

TECHNICAL CHARACTERISTICS

Mapegel UTT System is a hydrophilic gel based on acrylic and methacrylic monomers, consisting of 3 components: · component 1 = acrylic resin in acqueous solution; · component 2 = hardener in acqueous solution; · component 3 = powder accelerating salt. Thanks to its low viscosity, Mapegel UTT System is able to easily penetrate micro-porosity and small cracks by sealing them perfectly. After hardening, Mapegel UTT System has a high elasticity watertightness and excellent chemical resistance towards the main organic and inorganic liquids. Mapegel UTT System is perfectly compatible with Mapeplan waterproofing systems.

APPLICATION PROCEDURE

Preparation of the product Once the reaction time has been fixed (see table 1 below), the preparation of the product must be carried out following the procedure below. Solution A: Pour into a clean plastic container 25 kg of component 1 and add, while mixing, the entire content of component 2 (2.5 kg). Solution B: In a second container, pour component 3 in water (see Tab. 1). N.B.: the final mixing ratio between solution A and solution B must be 1 : 1. Do not use metal tools for preparation. In case of using a drill, it’s better to prefer plastic mixers or, if mixing should be done manually, use wooden equipment. By increasing or reducing component 2 or component 3, reaction times can be modified
