Static consolidation of walls by injections A few hints on how to work. The procedure entails injecting a cement mix into a wall at a pressure which varies according to case. The mix replaces the degraded mortar by filling the wall’s fractures and gaps The greater the penetration, the more efficient the result. Preparing the wall. After ensuring the building site is safe, the tapping test technique is used to find which zones need consolidating. Next the holes are made (3-4 at m2) by rotation coring machines, to thus avoid dangerous vibrations. The next step is to wash the structure adequately, pumping water as much water as it can take. Then, any existing fractures are stuccoed, and, finally, the mixture can be injected, starting from the bottom, and fitting an appropriate expansion nozzle in the holes. Preparing the mixture and adjusting pressure. After the mixture has been prepared at a ratio of approximately 0.5 - 0.8, injecting pressure should be adjusted with either the pressure-switch or the pressure gauge supplied with the pump. This adjustment is particularly important if crumbling structures are involved - pressure must be in the range from 0.5 to 1.5 bar. When pumping heights are considerable, loss load must be considered, by verifying pressure at the highest point with the in line pressure gauge.

Injections are one of the most versatile technologies in terms of their application possibilities. With its comprehensive range of mixers - injectors, BUNKER has what it takes to meet the multiplicity of use requirements.

WITH SAFETY AND RELIABILITY The electric panel, protected against impact and water sprays, conforms to European directives. Made with highly reliable components, it supports the many ON/OFF activations typical of pressure control pumps. It is equipped with a thermal cut-out for the electric motors, a handy phase inverter and an emergency push-button. The hour counter (standard supply) helps you plan both work and maintenance. All pumps with the electronic pumping facility are supplied with a button-board with 20 metre cable. This means the operator can activate it directly from the...
