Penetrating into building structures moisture is a serious cause of the destruction of foundations. Protection against water penetration (waterproofing) is an important factor in the preservation and durability of buildings.
At a high level of standing of ground waters there is a danger of their penetration into the basements, the formation of leaks and damp spots on the walls. Capillary moisture, rising along the pores in the foundation massif and the basement from the wet ground, can spread into the masonry of the walls of the lower floors. In case of aggressive groundwater, the foundation materials and underground parts of the building may collapse. To protect the building from groundwater, measures are envisaged to combat the movement of groundwater and the penetration of atmospheric precipitation into the ground of the base and arrange a protective waterproofing from the penetration of ground moisture into the structure of the building. Great options now come with the waterproofing contractor Singapore.
Finding the Right Source:
To prevent the penetration of rainwater and melt water into the underground parts of the building, plan the surface of the plot for building, creating the necessary bias for the removal of surface water from the building. Around the building along the outer walls arrange a blind area of dense waterproof materials (asphalt, asphalt concrete, etc.).
Asphalt concrete or asphalt concrete is the building material formed as a result of solidification of a compacted mass consisting of carefully mixed components of crushed stone or gravel, sand, mineral powder and bitumen taken in rationally selected quantities.
To protect against penetration of soil moisture in the structure of a building during new construction, external insulation of structures from the side of water is usually performed, and for the old building, internal waterproofing is applied in basements.
There are three types of waterproofing, corresponding to the types of water exposure – non-pressure, anti-head and anti-capillary.
- Non – pressure waterproofing is performed to protect against temporary exposure to moisture from atmospheric precipitation, seasonal perch, as well as in drained floors and ceilings;
- Anti-waterproofing – to protect enclosing structures (floors, walls, foundations) from the hydrostatic backwater of groundwater;
- Anti -capillary – for insulation of building walls in the area of capillary rise of ground moisture.
The device for waterproofing basements is determined by the nature of the impact of water, a feature of drained structures and materials, as well as functional requirements for facilities for operation, purpose and permissible humidity. This affects the choice of the type and material of insulation, determined by the necessary parameters for water permeability, water resistance, vapor permeability and durability. The opportunities of contractors, the season and the pace of work should also be taken into account when selecting waterproofing materials.
