Waterproofing is the combination of materials used to prevent water intrusion into the structural elements of a building or its finished spaces. Its main purpose is to resist hydrostatic pressure exerted by moisture in the liquid state. Waterproofing membranes consist of waterproof plastic, rubber, or coated-fabric materials.
For those who want a more durable, lower-maintenance roofing option, the modified bitumen roofing system is quickly becoming the most popular alternative for flat or low-sloping roofs.
In waterproofing, this rigid liquid membrane was tried with fibreglass reinforcing mats. The systems failed because coefficients of thermal expansion of concrete and rigid PU membrane being different lateral movement or creep occurred with the passage on one working climatic cycle.
When exposed to ultra violet rays or direct sunlight most polyurethane rigid membranes became brittle and crumbled. Waterproofing membranes consist of waterproof plastic, rubber, or coated-fabric materials.
Install heavy roofing felt with overtop your decking, old roof or insulation. Using cap nails, secure the felt in rows along the top and bottom of the sheets, as well as a row in the middle.Install drip edge flashing, and apply a primer so the roofing will adhere to it.
Like polyurethane is also a two-component system having a base resin and a reactor or curing agent. Base resin is obtained by dissolving bis-phenol A flakes in epichlorohydrin. This base is available in various viscosity ranges to suit different application conditions.
There is also the option of using a root resistant cap sheet, making this waterproofing system ideal for green roof situations. BBA certification is granted for the entire system and for when it incorporates our Plant E cap sheet for root resistant green roof waterproofing.
Because of its initial cost and material properties, the modified bitumen roofing system was almost exclusively used for commercial and industrial roofing applications. For example, modified bitumen roofing solutions cost more than traditional asphalt roofing options, but it is well-known for its strength.
Negative side waterproofing is applied to the interior face of a structure. It keeps water from entering an occupied space and is applied to what is known as the dry face.
Negative side waterproofing is primarily used for water holding purposes, but it does not prevent the water from entering the substrate (wall). The materials used for negative waterproofing must be able to withstand hydrostatic pressure.
Usually a permit isn’t required to simply replace small sections of a roof or lay modified bitumen membrane material over existing roofing materials. Modified bitumen roofing systems that require hot processing to secure the roofing sheets to the structure are generally installed by a licensed contractor who has experience working with that specific roofing material.
The base sheets build up the layers of modified bitumen for added durability and strength. The adhesive serves to attach the roofing material to the existing building infrastructure and gives it water resistance for protection against the elements.
Surfacing is a compound that is applied either manually or via the manufacturing process to protect the roof against undue wear from ultraviolet light.
