Curtain injection

In order to subsequently protect structural elements not accessible from the outside or only with great effort against penetrating humidity, curtain injection is a proved method to inject sealing material (gel) from the inside to the outside. Planning and supervision of the work are the task of a specialist. He determines the execution (diameter, angle, etc.) and pattern (distances, staggered, etc.) of the drill holes, selects the material, the appropriate packers and accessories, and specifies the required injection parameters (pressure, quantity per packer, etc.) to inject the sealing material safely through the structural element into the soil behind. A hemispherical injection body (gel-earth-mixture) forms in front of the outlets of the injection material. Note: Injections into the ground are due for notification or even subject to authorisation.
