A very important constructive element of house building is the base. The concrete base is capable of accumulating moisture coming from groundwater or precipitation, which leads to deformation of the device, i.e. shrinkage and destruction.
Waterproofing of the foundation
The experts offer to consider one of the options for protecting the support elements, namely how the foundations of buildings are insulated from the walls with sheets of roofing material.
First of all, it is necessary to take into account the characteristic properties of the relief of a given locality and the depth of occurrence of the aquifer. Knowing this, you can significantly protect the design from the effects of the external environment and plan the construction of housing in several floors. The support from the waterproofing specialist Singapore is important here.
The ruberoid isolation with proper care will last for several decades. The material itself is widely known and affordable. What does it include the technological process of protecting foundations from humidity and on what features should attention be paid?
Material used
A ruberoid is a cardboard that is first smeared with low-melting bitumen, then covered from both sides with refractory bitumen. To roll sheets do not stick together when folded, they are sprinkled with a special powder on top.
The disadvantage is the instability to the environment. It becomes brittle and easily torn. The flooring must be protected from sunlight.
Preparatory work
Immediately before the start of production, the surface is thoroughly cleaned of dirt and grease spots. On the basis there should be no cracks, chips, etc. If such defects are detected, the cuttings are cut and processed, the irregularities are sealed and ground with sandpaper, the cracks are covered with plaster. Preparatory stage
The corners of the foundation are rounded. Cuts are made – this is necessary for a strong connection of insulation with the base. The pieces of ruberoid are brought to the place of application and unwound.
Important! To ensure the durability and quality of the flooring, the prepared materials are applied to a dry surface. For this, under normal conditions, the structure is dried and covered.
Waterproofing device
The laying process consists of layer-by-layer gluing of the roll material by means of a special composition. The work is carried out at a positive air temperature. To protect the building structure from the penetration of water, the foundations of buildings are isolated from the walls by sheets of roofing paper of the grade PPP.
- First, the prepared surface is blotted with a solution (primer) and dried. Then a layer of finished mastic (bitumen) is applied to the area of the structure, onto which a uniformly heated roofing material is laid.
- There are two methods of waterproofing: horizontal and vertical. The first is done manually, where the base is laid between the walls of the basement and the basement. The work is carried out with grippers to the height of the part of the structure, using a scaffold if necessary. The panels are glued from the bottom to the top, strictly observing the overlap along the length and width.
With vertical laying of the flooring, the insulating coating is applied to the walls. The technology of the device is similar to the previous one, only the altitude parameters are taken into account, at high rates of which the carpet is doweled. The seams between the panels, lapping, are welded with hot air. At the end, the flooring is covered with a protective layer.
