Waterproofing chimney

click fraud protection

In houses with stove heating or decorative fireplaces important step in the implementation of quality roofing waterproofing is a chimney.The place where the pipe comes out, subjected to high loads: temperature changes, mechanical stress and high humidity, so the chimney waterproofing should be given special attention.

waterproofing principle

In place of passage of the pipe through the roof is required to obtain clearances and their usual waterproofing mastics and sealants - for lack of a measure of protection against leaks.Therefore, when laying roofing must perform a variety of activities:

  • Positioning tube should be as close as possible to the ridge of the roof, it will help prevent snow accumulation at the site of its output to the outside;
  • Under roofing stack exhaust water system, the protective membrane and the so-called "apron" and "tie".Its shape depends on the shape of the pipe;
  • pipe outlet locations need to seal the special sealant, resistant to temperature extremes;
  • on roofing fit additional decorative apron.His appointment - drainage of rain water flows from a pipe.

chimney, are known to have a different shape, so waterproofing design elements somewhat different for them.

Waterproofing chimney rectangular

Such pipes are often made of brick.Inside the brick boxes can take place asbestos cement or metal pipe, or can be made via the chimney masonry.Brick has good insulating properties, so a sharp temperature drop in a pipe, usually does not happen.

to perform gidoroizolyatsii pipe needed:

  • diffusion membrane;
  • waterproofing mastic;
  • Sheet Metal and fabricated metal aprons and ties on the size of the pipe;
  • Heat-resistant sealant.

waterproofing technology:

  1. begin implementation of the waterproofing should be immediately after laying the waterproofing roofing.The edges of the diffusion film are bent on a pipe with overlapping and glued using a polymer-bitumen mastic.

  3. Perform crate under the domestic apron at a distance of 5-10 cm from the pipe.Wooden sticks for extra protection can handle bioognezaschitnym composition.

  4. Install aprons, also starting from the bottom.Aprons should be above the roof covering is 10-15 cm and cover the roof on all sides by 20-30 cm. If the roof slope less than 20 degrees, the lower apron can be made up to the eaves, it will improve the waterproofing properties of the roof.

  7. After installing aprons proceed to laying of roofing: it is placed on top of the skirt flush with the tube, trying to make the minimum clearances.

material stacking technology Vakafleks

Vakafleks - Self-adhesive plastic waterproofing tape.Vakafleks aluminum has an internal reinforcement, so that the profile may take the form of roofing, while adhering to the tube.Vakafleksa Installation is simple, it can carry one person.

  1. tape starts to stick to the bottom edge of the pipe.Cut it along the length of the wall with a margin of three to five cm on each side.Flex half lengthwise, remove the upper half of the protective layer and stick the tape to the pipe, laminating it hard roller.Then remove the lower protective film and adhered to the roof covering, the laminating roller to thoroughly until it achieves a complete fit.Angles tape neatly trimmed, folded to the side walls of the pipe and glued.

  3. upper wall of the tube is glued in the last instance, the corners are turned to the side plane.For best be glued hydroprotection another strip of tape on the pipe above the roof covering, and all joints should be stacked so that the upper layer is above the direction of water flow.

Waterproofing chimney circular section

Recently flue gases are increasingly set round sandwich pipes.They are easy to install and are less expensive to the same fireproof and do not create unnecessary burdens on the foundation of the furnace.Waterproofing of such pipes is fairly simple.This requires special pipe penetrations.They are aluminum or steel frame made of sheet metal with a flexible apron of a polymeric material.Penetrations are available in different colors, allowing it to pick up the color of the roof.

technology waterproofing round tube:

  1. Before laying roofing tunneling try on and, if necessary, make additional crate next to the pipe, which will be attached to the excavation.
  2. Lay roofing.Sheets thus easier to cut, so that the joint comes just through a tube.
  3. carved in the sinking of a hole of the required diameter, tunneling put on the pipe, put it on the roof covering and attach the base form of the coating profile.
  4. Joints coat with heat-resistant sealant for pipes.
  5. Secure the base to the roof penetration using screws.
  6. Screws fastened to advance the equipped crate with a step of 7-10 cm.
