The Kalmastop hydraulic plug is needed where water flows under pressure and ordinary mortar does not have time to set: a small portion of the mix is gauged with water, formed into a ball and pressed into the opened-up crack. Setting starts after 1–1.5 min and ends after 2 min, and after 1 h the compressive strength is at least 10 MPa. The compound is used in basements, foundations, tanks, tunnels and the metro; after the leak is stopped, the area is sealed with Kalmatron or Kalmatron-Ekonom.
| Manufacturer | Kalmatron — OOO “Kalmatron-SPb”, Saint Petersburg |
|---|---|
| Type | hydraulic plugs |
| Use | leak repair, tunnels and metro, tanks and pools, foundations and basements |
| Base | rapid-hardening cement-based dry mix: various cements, sand of defined grading, a complex of chemically active reagents; aggregate size max 0.63 mm |
| Colour | grey (free-flowing grey powder) |
| Packaging | 3 kg polyethylene buckets |
| Application method | open up pressurised cracks to a depth of at least 30 mm and a width of at least 20 mm, widening inwards (dovetail), then flush; mix no more than 1 kg of the mix at a time, water 190–200 ml per 1 kg, mix by hand in gloves for 40–50 s to a moist-earth consistency, form a ball; press into the crack and hold for 2 min (5–6 min for a strong leak); vertical leaks — from top to bottom; after ~1 h seal with Kalmatron or Kalmatron-Ekonom; in cold weather — warm water not above +35 °C; adding more water later is prohibited |
| Application temperature | not below +5 °C |
| Curing | initial setting 1–1.5 min, final setting 2 min (GOST 310.3-76); in cold weather setting takes longer, in hot weather it is instantaneous |
| Key properties | compressive strength after 1 h at least 10 MPa, after 28 days at least 35 MPa (GOST 310.4-81); adhesion to concrete at least 2 MPa (GOST 31356-2007); watertightness at least W12 (GOST 12730.5-84); frost resistance at least F1 300 (GOST 5802-86); eliminates leaks under a constant water inflow; service -60…+130 °C |
| Consumption | 1.5 kg/dm³ |
