As a specialist designer, we work with architects and engineers to provide a consulting design service. As the link between designer and contractor we are passionate about creating a design with is compliant and practicable. It is extremely important to achieve a waterproofing design which can be easily installed on site, our valuable experience allows us to effectively assist in the creation of these detail designs.
We attend design meetings and advise on waterproofing strategy from concept to completion, we understand how many changes a building design encounters between concept to completion and we welcome the exploration of different options. Challenges brought to us by complex basements and unusual construction methods have led us to explore many different ways of doing things and forced us to become more innovative in our approach.
All of our designs and quality control systems are compliant with BS8102:2009, which is the standard for structural waterproofing within UK construction. As an adviser to specifiers, we expect to achieve compliance with BS8102:2009 as a minimum requirement. Our designs and quality control procedures seek to redefine waterproofing, we seek to cost effectively achieve over and above the standard requirements for structural waterproofing. Providing designs for the sealing of concrete requires us to also work within the requirements of BSen934-1, BSen934-1 and BS EN 13670:2009, these are the standards for concrete design and placement.
Basements are graded into three groups according to their intended use. The British Standard defines underground spaces into three grades
Type 1 structures can have some seepage and damp is tolerable, these would be car parks
These structures can accept damp but no water penetration, examples include Plant rooms and workshops.
Type 3 Structures are typically living accommodation grade and can accept no damp or water penetration.
Waterproofing Barriers are grouped into three categories
When designing a waterproofing system the following points are helpful to consider:
With these two points, we design where required with a combined waterproofing system. The design will either have a Type A and B barrier or a Type B and C barrier and so on.
Whilst it is essential to get the designs and specifications right, it is a fruitless endeavor if the installation is poor. FIS concentrate on making sure the installation is correct. We provide unlimited site support which included installation training and quality control physical inspections. We also provide free use of Premtrac, this is custom built online portal for recording waterproofing installations and the information relating to the installation.
It is unrealistic and unreasonable for waterproofing designs to rely on installation and workmanship to be without fault. This means we should allow for workmanship error within the design but it doesn’t then make it acceptable for shoddy installation. With our regular onsite presence and our unique online portal we are able to ensure the waterproofing is installed correctly.
