• As horizontal barrier against rising damp in masonry work
• Can be used without pressure and with low pressure techniques

Creation of drill holes

1. The drill hole spacing and the arrangement of the drill holes (1-row or 2-row) depends on the absorbency of the masonry work. The closer the drill hole spacing, the greater the certainty for the success of the measure.
2. As a rule, drill holes with a diameter of 30 mm are drilled at a distance of approx. 10 – 12.5 cm and an angle of inclination between 30° and 45°. The drilled hole depth is approx. 5cm less than the masonry thickness. When specifying the drilling angle be aware of the requirement to cover at least one bed joint, and a minimum of 2 bed joints with thicker masonry work.
3. The drilled hole depth is approx. 2 cm (pressureless injection) or approx. 5 cm (low-pressure injection) less than the masonry work thickness.
4. For low or non-absorbent substrates, it is recommended to arrange the drill holes in two levels in the joint area. The height difference should be <8 cm.
5. With absorbent natural stone masonry, place the drill holes in the stone and with dense quarry stone masonry in the joints.
6. Prior to injection, dust from drilling must be removed thoroughly to ensure maximum possible absorption of the active substance in the masonry work
