Water-swellable Waterstop Glue Manufacturer @ One-component Polyurethane Sealant
Basement engineering leakage and plugging method with water-swelling water-stopping glue
Basement works
1. Water seepage on the side wall and bottom plate
the reason:
(1) The construction quality of the concrete is poor, with micro-pore penetration;
(2) The waterproof coating is not firmly bonded or damaged.
Leakage prevention measures:
(1) Clean up the water seepage parts, use water-swellable water-stopping glue to stop the seepage treatment or use grouting to stop the leakage treatment.
(2) After cleaning the water seepage area, use water-swellable water-stop glue and other polyester reinforced cloth for waterproof treatment.
2. The cause of serious water leakage in the basement:
(1) Poor concrete mix ratio and construction quality, there are holes for irrigation;
(2) Cracks in the basement due to various reasons;
(3) The construction quality of the waterproof coating is not good or the extension of the waterproof coating is not enough, which causes the waterproof layer to crack.
Leakage prevention measures:
In addition to the use of high-pressure grouting inside and behind the wall to plug the leak, the base surface is cleaned after the leaking part is plugged, and the water-swelling water-stopping glue or two-component polysulfide sealant is used for waterproofing and strengthening treatment. 13785855258 pay
3. Leakage at deformation joints, construction joints and new and old structural joints
the reason:
(1) Poor concrete quality, excessive shrinkage and cracks;
(2) The details of these parts are not properly waterproofed, such as the improper placement of the water stop, the insufficient pouring of concrete, and the incomplete filling of caulking paste;
(3) The elongation of the sealing material and waterproof coating is not enough, and it is pulled or separated from the bonding surface.
Leakage prevention measures:
(1) Pre-treat the water-stopping water-stopping glue on the surface of the leaking part, and then inject the two-component polyurethane sealant prepolymer with a high-pressure grouting plugging machine;
(2) Use water-swellable water-stopping glue or polysulfide sealant on the surface to do waterproof reinforcement treatment.
The history of stone carving can be traced back to the middle of the Paleolithic Age, which is about 120000 years ago. Since then, stone carvings have been handed down to this day. In this long history, the creation of stone carving art has been constantly updated and improved. In different periods, there were great changes in the types and styles of stone carvings; Different needs, different aesthetic pursuits, different social environments and social systems are restricting the development and evolution of stone carving creation. The history of stone carving is not only the history of art, but also the history of rich cultural connotation. It is more vivid and real human history.
