Waterproofing is the process of making an object or structure waterproof or water-resistant so that it remains relatively unaffected by water or resisting the ingress of water under specified conditions. Permeation of water vapour through a material or structure is reported as a moisture vapour transmission rate. Water resistant and waterproof often refer to penetration of water in its liquid state and possibly under pressure, whereas damp proof refers to resistance to humidity or dampness.
- Cementitious Waterproofing: – This method is often used in the internal wet areas such as toilets. This method is usually a rigid or semi-flexible type waterproofing, but since it is used in internal areas such as toilets, it is not exposed to sunlight and weathering. Thus cementitious waterproofing does not go through contract and expansion process.
- Liquid Waterproofing Membrane: – Liquid membrane is a thin coating which consists of usually a primer coat and two coats of top coats which are applied by spray, roller, or trowel. It offers more flexibility than the cementitious types of waterproofing.
- Bituminous Membrane: – Bituminous membrane waterproofing is a popular method used for low-sloped roofs due to their proven performance. Bituminous waterproofing membrane have torch on membrane and self-adhesive membrane.
Self-adhesive compounds comprise asphalt, polymers and filler; additionally, certain resins and oils may be added to improve adhesion characteristics. The self-adhesive type has low shelf life as bonding properties of the membrane reduces with time.
Torch on membrane have exposed and covered types. Exposed membrane often has mineral granular aggregate to withstand the wear and tear of the weathering and the other types of membrane, contractor need to apply one protective screed to prevent the puncture of the membrane.
- Polyurethane Liquid Membrane: – Polyurethane liquid membrane method of waterproofing is used for the flat roof area and exposed to weathering. This waterproofing method is expensive.
- Joint Sealant: – The purpose of joint sealant is to minimize infiltration of surface water and incompressible material into the joint system.
Roots Qatar cover the full range of interior and exterior waterproofing applications, from basement tanking and under-tile for steam rooms, to roofing, ground works and tunnels. Simple to apply and always safe to use, our waterproof sealants work with the full range of porous backgrounds, including timber, concrete, brick, stone, metal and cement board.
