Application of both sheet and liquid waterproofing Membrane on flat roofs, decks, retaining walls, planter boxes and balconies. Internal wet Areas, Bathrooms, Laundries and Basement walls Leak Detection and Rectification. Wet Basement – Car Park Problems.
Sheet waterproofing membrane: As the name implies, these are waterproofing membrane membranes that arrive at the site in the form of rolls. These are then unfurled lay in an area. The most common type of sheet based membrane is a bituminous waterproofing membrane. This type of waterproofing membrane is stuck to the substrate with its molten part of bituminous using blowtorches.
Joints between adjacent membranes are also made with the same molten bituminous. The sheets overlap by about 100mm (4″) to form a waterproof joint.
With this type of membrane, joints between sheets are critical, and you must do perfectly to avoid leakage.
Other types of sheet based membranes are PVC membranes and composite membranes. The latter have a fabric base that provides strength and tear resistance, and a chemical that coats the fabric to provide resistance.
Since these membranes produce excepting the joints, because they are consistent in quality
Liquid membrane: Liquid membranes come to the site in liquid form, which spray gun or paint brushes apply liquid waterproofing membrane on the surface.Therefore The liquid cures in the air to form a seamless, joint-free membrane. Because The thickness can control by applying more of the liquid chemical per unit area.
Since the application procedure is very quick, a contractor will try and finish the entire area to be waterproofed in a single day to avoid cold joints. However, if a very large area is to be done on successive days, cold joints can easily be done by overlapping the new membrane over the old – the chemical will stick to itself readily.
The membrane can tear or break if it is too thin. Therefore The adhesion of the membrane to concrete must be good.We will not disappoint you .You will be served by a friendly and highly experienced waterproofer.
