Slotted wall, drilled pile wall and sheet pile wall sealant

Deep construction pits required enclosing walls to even out the applied earth thrust. Here we differentiate between slotted walls, drilled pile walls and sheet pile walls.

The above named variations are all composed of multiple pieces joined together, and it is these joints which can allow water seepage to occur.

Water seepage is undesirable due to the following reasons:

• When rinsing fine particles out of the layers of foundation soil, hollow spaces can be formed which the lead to fissures and settlement.
• The permeating water becomes a hindrance to the construction work or even makes further work impossible.
• Depending on the region, laws regarding water prohibit groundwater from be pumped out.
• Even when allowed, the costs involved with sump drainage on-site should not be underestimated.

The VARIOSEAL sealant system provides for an injection in the case of enclosing wall joints. In this procedure an injection agent is used which reacts only with water to form a sealing polymerization. The injection agent used by VARIOSEAL in this situation reacts based on the amount of rising water as well as the amount of water pressure. The higher the amount of water and pressure, the quicker the VARIOSEAL injection agents begins to work.

This injection system has many advantages over other conventional methods:

• The problem area is sealed immediately, directly at the site of leakage.
• The results of the restoration can be inspected immediately.
• The reaction always matches the need, due to the water-reactive injection agent.
• Environmental tolerability.
• Can be used even in cases of strong water pressure.
• Proven, guaranteed protection against corrosion for steel reinforcements, because the use of salts is completely eliminated.
