Injection method for masonry with cavities
Due to a multistage injection in a low-pressure process, cavities, defects and fissures are filled with a shrinkage-free injection mortar via bore packers. Using the same packers, a drill channel is created by a lance. The injection material is then injected by pressure injection (3-5 bar) for better distribution. In this way an optimal effectiveness in the area of the injected masonry can be achieved.

Horizontal sealing / Horizontal barriers
Subsequent injection against capillary ascending moisture

open PDF

Objectives

Prevention of moisture flow by capillary action

Moisture content in equilibrium with environment

Prevention of capillary moisture replenishment above the injection zone

Objectives of low-pressure injection

In the case of masonry of homogenous materials

In the case of masonry with a high rate of moisture transport

Consistent and rapid distribution of injection material throughout the masonry

Advantages

Machine pressure injection contributes to optimal distribution of filling material in masonry

Packer systems and fittings optimized for the technique

Strengthening and stabilization of masonry in the injection area

Low consumption of injection fluid through filling of internal cavities

Types of packers

Bore packers (steel)

Drive-in packers (polymer)

Requirements with regard to Injection and Mixing Equipment

Cross section adjusted to the flow characteristics of the injection material

Pressure controlled and limited to between 1 and 15 bar

Corrosion resistance of all equipment parts vis-a-vis injection material

Homogenous mixing of injection material

Consistent mixing quality

Keeping the injection material in motion

Pump performance and flow suitable to the masonry

Note

The horizontal seal should only be injected above the pressure and water line

Wet-on-Wet Technique and Multistage Injection (INJECTION PASTE AND MICRO EMULSION)

Objectives of the Wet-on-Wet Technique

Filling of the internal cavities to create an injection zone to contain the micro emulsion

Stabilization of the masonry in the area being injected

Increase of alkalinity in the area injected to allow the micro emulsion to react

Filling materials

Injection of paste (step 1)

to fill cavities and crevices

Injection of micro emulsion (step 2)

to create a horizontal seal

Objectives of Multistage Injection

In the case of masonry of homogenous materials and a low alkalinity, the chemical reaction is started using an activator

Procedure Wet-on-Wet Technique – Step 1

Prepare drilling by marking the positions of holes every 10 to 12.5 cm (4 to 5 inches) then drill and remove dust with a moist cloth or brush

Insert packers, clamp, and attach shut-off pieces

Mix injection paste

Fill the injection pump with mixed material

Inject the drill holes at a pressure of approximately 2 bar (depending on masonry)

Procedure Wet-on-Wet Technique – Step 2

When injection pressure has dropped sufficiently (when material stops flowing out of the shut-off piece) insert the test lance into the packer. The channel for the second injection is ready when the injection paste has hardened enough that the test lance can be withdrawn

Mix micro emulsion and inject into drill holes at a pressure of approximately 5 bar (depending on masonry)
