Waterproofing
Waterproofing any site is a pivotal stage of the build, preventing water damage to the foundations, which could cause harm to the construction should the problem persist.
BS8102:2009 is the code of practice for protection of below ground structures against water from the ground.
The British Standard gives information on what waterproofing methods are available and what specifications the various products should meet.
The three types of waterproofing covered under BS8102:2009 are:
• Type A: Barrier system applied internally or externally (membrane, cementitious etc.)
• Type B: Water tight concrete
• Type C: Cavity drain
BS8102:2009 also states that if the risk is high, two methods of protection should be considered (dual system approach) and all waterproofing designs should consider maintainability and reparability. SIG’s core waterproofing manufacturers all supply products that comply with the standards outlined in BS8102:2009 which makes them the safest products to use when waterproofing structures.
An Unrivalled Product Range
At SIG Distribution we offer an unrivalled range of products to the construction industry, including a number of products for Waterproofing.
CEMENTITIOUS
Cementitious waterproofing solutions are easy to mix and apply. These are often used in reparation projects and many of the solutions we supply can be spray or brush applied and offer rapid hardening, saving both time and money.
CAVITY DRAINAGE
Despite putting waterproofing systems in place, there is the possibility that water will still infiltrate the structure. Using a cavity drainage system to guide water away from the structure helps to comply with BS8102:2009 and the requirement to have a maintainable waterproofing system.
WATERBAR
A flexible material embedded within concrete structures, limiting the passage of water through concrete joints. They are available in a range of materials dependent on the movement and pressure of water.
PRE-APPLIED MEMBRANES
These membranes are installed prior to the concrete pour to prevent the infiltration of groundwater. When the concrete is poured onto the membrane, a mechanical bond is formed preventing the likelihood of water ingress or water tracking. The product itself is tough and highly durable, creating a resistant and long lasting solution for waterproofing.
POST-APPLIED MEMBRANES
These membranes are installed after the concrete pour to provide a watertight seal between the membrane and the concrete. So, even if damaged, water is unable to access a structure and damage the foundations. These membranes are available in a range of grades, to ensure they cater to every project and can work to their maximum efficiency.
LIQUID APPLIED
Liquid applied solutions are effective in areas where traditional membranes would be difficult. These can be applied to surfaces by rolling, brushing and spraying, ensuring the waterproofing is continuous.
BENTONITE MEMBRANES
SIG stock and supply bentonite membrane from market leading manufacturers. A unique feature of using a sodium bentonite membrane is that it is self-healing. It is also capable of repeated cycles of wetting and drying without deterioration of its sealing properties.
