<h2>Mapei Mapegrout SV is a fast-setting and hardening, shrinkage compensated, easy flow mortar for repairing concrete and fixing inspection shafts, manholes and highway coating materials.</h2> <p>Mapegrout SV is a one-component, pre-blended mortar in powder form, made up of specific hydraulic binders, high-strength cement, graded aggregates and special admixtures according to a formula developed in Mapei's Research Laboratories. By varying the amount of mixing water accordingly, Mapegrout SV takes on either a fluid or highly fluid consistency. This makes the mortar suitable for casting, even at a greater thickness (up to 5 cm), into formwork or a defined space, without the risk of segregation.</p> <p>For thicknesses over 5 cm, Mapegrout SV must be blended with 40% of Gravel 6/10. Thanks to its fast-setting properties, Mapegrout SV may take light foot traffic and may be even subject to wheeled traffic after approximately 2 hours from application at a temperature of +20°C.</p> <p><br />Its special composition and the special admixtures contained in the product give the mortar high mechanical strength even after a very long period of time, and make it waterproof and with high resistance to abrasion. Mapegrout SV meets the requirements defined by EN 1504-9 (“Products and systems for the protection and repair of concrete structures - Definitions, requirements, quality control and evaluation of conformity - General principles for the use of products and systems”) and the minimum requirements claimed by EN 1504-3 (“Structural and non structural repair”) for structural mortars of class R4.</p> <h3>Best Uses</h3> <p>Mapei Mapegrout SV is best suited for repairing badly-damaged concrete structures which require the use of high flowing mortars. Mapei Mapeigrout SV is also suiatble for repairing industrial floorings, highways and airport works which need to be reopened to traffic within a short space of time and rapid fixing of inspection shafts and manholes.</p> <h3>Some Application Examples</h3> <ul> <li>Repairing concrete floorings for industrial use such as shopping centres and warehouses</li> <li>Repairing concrete floorings in airports</li> <li>Repairing pedestrian concrete pavements</li> <li>Fixing road signs</li> <li>Fixing concrete pylons for electricity lines or telephone lines</li> <li>Fixing fencing</li> <li>Fixing general highway coating materials</li> <li>Anchoring kerbstones and protection barriers</li> <li>Fixing drain covers and gas, electric and phone-line inspection shafts</li> </ul> <h3>Application</h3> <p>Remove damaged or loose concrete until a sound, strong and rough substrate is obtained. Eliminate traces of paint, oil, powder and any other material which may impede the adhesion of Mapegrout SV to the substrate. Saturate the substrate with water. Before casting, wait until the excess water has evaporated. If necessary, this phase may be speeded up by using compressed air.</p> <p><strong>Preparation of the mortar</strong><br />Pour 12-13% of water (3.0-3.25 litres for each 25 kg bag), according to the consistency required, into a cement mixer. Slowly add Mapegrout SV and mix for 1-2 minutes. Remove all traces of powder not perfectly blended from the inside surface of the mixer and continue mixing for 2-3 minutes, until a completely homogenous paste is obtained. If the thickness to be laid is greater than 5 cm, mix Mapegrout SV with 40% of Gravel 6/10 and use 14% water for mixing (by weight of the mortar - 3.5 litres for each bag of Mapegrout SV). Mapegrout SV remains workable for approximately 15 minutes at a temperature of +20°C.</p> <p><strong>Applying The Mortar</strong></p> <p>Pour Mapegrout SV into the area prepared without the use of vibration, and smooth off the surface immediately with a trowel. If necessary, after laying inspection shafts or manholes, re-asphalt the area. A thickness of at least 3 cm is recommended to allow the bitumen layer to adhere well and to withstand the passage of traffic without yielding.</p>
