What do we need?

The walls of the underground are usually constructed of reinforced concrete. Often due to poor workmanship or from other causes cracks shown on the wall, so  water pass from the outside to the inside. Sometimes because of the large porosity of the concrete, shows a water leak from the entire surface of the masonry. When the problem occurs, usually there is no access to the outer space to make the restoration of the problem. The restoration of the problem should be done by the interior. The materials to be used should withstand high water pressure where will be exercised and comes from the outside .

How do we do it?

It will be an overall waterproofing  from the outer surface of the concrete using one component, brushable waterproofing slurry DSF 360.

Step by step

• First remove all loose, clean and wash the surfaces to be applied materials.
• Projecting irons are cut at a depth of 2 cm below the concrete surface. Also clean any corroded metal and fittings.
• Prime with primer WRM 510 all exposed metal parts on which to apply the brushable mortar.
• Crucify the acrylic primer high penetration GLX 292 FLEX PRIM on all surfaces of concrete, on which will be applied materials. Prime all surfaces with high penetration  acrylic primer GLX 292 FLEX Prim.
• Large cracks (> 1 mm) and gaps close with fiber reinforced repairing mortar WRM 525. If there are water leaks are sealed with super-fast setting sealant mortar WRM 500. Apply the  fiber reinforced, brushable waterproofing slurry DSF 360, four layers crosswise, with a stiff brush.
• Material must penetrate and fill all the gaps. Each layer is applied over the preceding when it is almost dry.
