Concrete injection: the solution to moisture problems in concrete walls

Cracks can appear in concrete structures, such as facades and walls, because of various reasons. These cracks can lead to moisture and stability problems, affecting the health of the concrete. If a damaged concrete wall is not treated, brittle concrete, loose pieces of concrete, concrete rot and moisture problems occur.

Concrete injections are an effective method for repairing, strengthening and waterproofing concrete walls. This technique involves injecting an injection fluid into the concrete. They repair and fill concrete cracks, concrete seams, gravel nests and voids, restoring the concrete to its original strength.

How do moisture problems occur in concrete walls?

Moisture problems in concrete walls often occur as a result of cracks in the wall, which in turn can be caused by various acting forces. Some possible causes include the following:

  • A bad bilge seam. This is where a concrete basement floor and the basement walls meet. When the bilge seam is not placed, poorly placed or worn out, cracks can appear.
  • A great construction weight.
  • When the concrete shrinks as it cures.
  • Ground movements.
  • Fluctuations in groundwater.
  • Thermal influences causing the concrete wall to expand on the one hand or shrink on the other.

When the stress exceeds the resistance of the concrete, cracks appear. This can also cause moisture problems arise. For example, the wall can no longer properly hold back rainwater from outside or groundwater, leaving you with penetrating moisture, rising damp or a damp cellar.

How does concrete injection work?

There are different methods and injection fluids when it comes to concrete injection. Which method best suits your situation depends on the cause of the damaged concrete wall and the purpose of the repair. This is best done by a moisture specialist examined.

Typically, having concrete injected has the following steps:

  • The first step involves a thorough inspection of the concrete surface to identify cracks, voids and other defects. Depending on the results of this inspection, the appropriate injection material is chosen. Often chosen fluids are epoxy, polyurethane or acrylic.
  • Next, strategic spots will be drilled holes in the concrete wall. The concrete liquid will be sprayed into these.
  • Concrete injections are used to fill all cracks, seams, gravel nests and voids in the concrete. By filling these voids and cracks, curing and levelling them, the concrete becomes stronger again.
  • All elements are joined, glued and sealed.

Concrete injections with AquaConsult

AquaConsult makes concrete walls bone-dry again with its concrete injections. We exclusively inject the robust ARTIPUR INJECT FLEX: a product developed to seal joints and cracks in concrete structures, even in the case of leaks with a high water flow rate and pressure. After this procedure, no drop of water can enter the interior space through the concrete wall.

ARTIPUR INJECT FLEX is a 1-component polyurethane injection resin catalysed with ARTIPUR CAT FLEX. The dosage of the catalyst determines the polymerisation time. In liquid phase, this product is a yellowish, transparent liquid that cures rapidly (depending on ambient temperature and catalyst dosage) in contact with water to form a tough, flexible closed-cell polyurethane foam.
