SOLONAX WS
Extruded plasticised PVC (PVC-P) and TPE waterstops that seal construction and expansion joints in water-retaining concrete. The range follows the DIN 18541 profile families — A and AA for construction joints, D and DA for expansion joints — in nominal widths of 190, 240, 320 and 500 mm, supplied in coils and butt-welded on site, with crosses, tees and corners prefabricated in the plant.
Why it is specified
- PVC-P compound meeting the DIN 18541 material requirements in every declared property
- Ribbed anchor profile develops the full water path length through the concrete section
- Centre bulb sized to the expected joint movement — inside diameter not less than the differential movement
- Width selected against the concrete section: w ≥ 6a + j and w ≤ t, with cover y ≥ 0.5(w − j)
- Crosses, tees and corners welded in the plant — the weakest point of a joint is not left to the site
- TPE grade for placement below −20 °C and for welding to TPO membranes
