Putty type water swelling seal product features
The putty-type water-expanding water-sealing strip has the function of water-swollen swelling and “stopping water with waterâ€; it has a slow swelling rate, and its swelling rate is ≤ 50% of the swelling rate during 186 hours of soaking; this product device is convenient in construction and low in price. In the long-term water immersion, no dissolved substances were separated; the difference compared with other hydrophilic expansion waterstops was that its hydrophilic swelling did not disappear after a long-term repeated expansion.
The correct installation steps for the water expansion seal:
1. After the interface of the concrete joint to be hardened is cured, the scum and dust on the interface are eliminated.
2, before hitting the construction joints on the other side of the concrete, the water will be covered with water and the putty seal strips will be removed. If it is a horizontal construction joint, it is bonded along the length of construction joints at the interface of construction joints and post-sealing joints. It is better to use cement nails or adhesives (401 glue); vertical construction joints and post-sealing joints are required. A 50-100cm cement nail is fixed so as not to shift.
Putty-type water-expanding water seal lap:
Combine the two squeezing slivers within 5cm of the end of the squeezing squeezing (or use a knife to shave the sloping sloping face), stack the splicing up and down, and press it by hand to make it tightly contact with the concrete and splicing. The middle is nailed with a concrete nail. Swelling water seal construction notice:
1. Fill the construction surface with mortar to ensure that there is no unevenness at the joint of the strip.
2. When horizontal waterstops are installed, they need to be fixed with screws or glued in order to avoid floating misalignment of rubber waterstops when irrigating cement.
