In the modern market there are 6 main types of waterproofing materials – penetrating waterproofing, roll waterproofing, painting waterproofing, cast, plaster and sprayed waterproofing. Let us dwell on each of them.
Penetrating waterproofing is used mainly for waterproofing concrete surfaces. It provides, through its cement base, the best adhesion to the concrete surface, penetrating all micro cracks and filling the pores of concrete. Simplicity of application (the composition is applied to the surface of an ordinary brush previously cleaned from dust and dirt), high performance characteristics, as well as a relatively low price are its main advantages. Of the minuses only a narrow field of application – concrete surfaces and concrete products without lime. The right waterproofing contractor singapore will help you out in the following.
Rolled waterproofing is used mainly for roof insulation
- All waterproofing materials of roll type require special attention to installation. At what half of the success depends on the correct preparation of the surface to be applied. When installing a waterproofing roll, follow the instructions strictly. Another disadvantage of this type of waterproofing is a short service life, up to 20 years maximum.
- Paint waterproofing is a mixture of the kind and structure very similar to ordinary paint. However, after drying, this coating forms a dense rubber film on the surface. As well as roll, paint waterproofing requires careful preparation of the surface – leveling, cleaning, degreasing and maximum drainage. Apply a waterproofing paint coat in two layers of 0.2 mm each. Among the disadvantages of such waterproofing material is the short service life, up to 6 years.
- Cast waterproofing is used mainly for concrete floors. Before it is applied, the surface is cleaned, treated with a primer, dried (preferably with a hot air stream). A protective fence is installed along the perimeter and the fill itself is made. The advantages of cast waterproofing can be attributed to the fact that as a result of a continuous waterproofing layer.
- Stucco waterproofing is similar in structure to penetrating waterproofing, but their composition is radically different. Stucco waterproofing is less effective and is used only for conventional walls. It requires several layers.
The sprayed waterproofing is qualitatively allocated due to the seamless coating, long service life (up to 40 years) and high efficiency. However, applying it requires special equipment and knowledge of technology.
So to block cracks in the walls, as well as to strengthen fine-grained soil, it is better to use acrylate gels. For waterproofing of above-ground concrete structures, polymeric resins and micro-cements are most effective.
