General Admixtures - MICRO - PROOF

In the field of structural waterproofing, General Admixtures offers a wide range of technologies for the realization of efficient, definitive and cost-effective solutions.‎ The MICRO-PROOF System is developed around the homonymous crystallizing additive, available both in the version for mass use (MICRO-PROOF) and in that applicable superficially on existing structures (MICRO-PROOF MF).‎ These products are able to react chemically with water and free lime present in the cement matrix to form a network of insoluble crystals that obstruct the porosities and micro-cracks inside the material.‎ The result is a significant reduction in the permeability of concrete, which thus becomes totally impermeable to water, while retaining the permeability to steam.‎ Principal features • Concrete waterproofing in both positive and negative thrust.‎ • Reduction of commissioning activities with elimination of waterproofing coatings or membranes.‎ • Permanent structural waterproofing.‎ • Protection of the structure from environmental attacks.‎ • Remarkable resistance to severe actions such as chlorides, aggressive waters, etc.‎.‎ • Healing effect of the structure over time.‎ • Increased mechanical strength of concrete over time.‎ The healing power of MICRO-PROOF remains over time.‎ In the absence of water, in fact, the product remains latent indefinitely in the cement matrix.‎ If, for whatever reason, a micro-fissure (up to 0.‎5 mm wide) should form and through it water should enter, MICRO-PROOF would crystallize immediately, sealing it in the bud.‎ Advantages • Speed of execution • Reduction of work on site • Intrinsic waterproofing of structures and elimination of waterproofing membranes • Self-closing of cracks up to 0,5 mm width • High durability to aggressive agents • Increase in nominal structure life Fields of use • Platform of foundation • Basements and elevator shaft • Maritime works, subject to chloride attack • Sewage treatment plants, slurry containment tanks, sewerage • Swimming pools, drinking water tanks, canals and water pipes • Fire and rain tanks • Tunnels, underpasses, box structures • Underground car parks
