Waterproofing Design Service


A Waterproofing Design Specialist provides expertise in structural waterproofing.


A Waterproofing Design Specialist should be appointed as part of the design team at the planning stage or as early as possible so that an integrated waterproofing solution is created.  All decision made by others that might have impact on the waterproofing deign should be brought to the attention of the Waterproofing Specialist, Design Team, and Installing Contractors. Final decisions and any recommendations should be approved by those taking overall responsibility for the design of the waterproofing. 

Identifying a Waterproofing Design Specialist can be difficult and daunting, Delta has their own in-house Technical Team who are able to offer Waterproofing Design Services. Our Waterproofing Design Consultants have:

  • Suitable qualifications and experience in Structural Waterproofing
  • Be able to list the principal considerations for a robust waterproofing design
  • Offer knowledge on waterproofing systems available
  • An in-depth understanding of BS 8102:2022 and its requirements
  • Able to assess risk and reducing risk in suitable waterproofing designs
  • Desk top study & risk assessment knowledge
  • An understanding of sources of water (such as how it flows through the soil and interacts with the structures)
  • Knowledge on all Types of waterproofing systems, their suitability to the project/an understanding of limitations on drainage options
  • Structural knowledge
  • Knowledge of Ground Gases
  • Geotechnical knowledge (to be able to understand the implications of a soil report)
  • The ability to produce a Design Report, Method Statements and Waterproof Design drawings
  • The ability to provide guidance that assists with and influences future maintenance of the waterproofed structure.


Maintainable Designs

 

Delta’s Waterproofing designs are designed and installed as a maintainable water management system. This is highlighted as a key requirement in BS 8102:2022, all components of the system should be accessible for both inspection and maintenance. 

 

Guarantees

 

Delta Membrane Systems Limited offer a 30-year Product Guarantee on membranes, seals, and fixings when a Delta Registered Installer has installed a Delta, Type C Cavity Drainage System.


Delta MS 500 Fire Retardant, Type C Waterproofing


Delta’s new innovative fire-retardant MS 500 membrane gives a unique opportunity to the structural waterproofing sector for Type C systems to be used in reducing the spread of fire or where installation has not previously been possible for fire safety reasons.


Delta’s new fire-retardant Type C Cavity Drainage System provides architectural freedom and allows systems to be used in not only deep basements but where national Building Regulations Euroclass B or C are required, meeting building requirements of today, but also that of tomorrow.

Delta MS 500 Fire offers a B-S2, d0 Euroclass fire rating (EN 13501-1:2018) whilst maintaining its strength, durability, functionality and workability.


The first and most important element of a Type C membrane is keeping structures dry. Water ingress will potentially result in a corrosive environment, with structures having a reduced life service. Delta MS 500 Fire Retardant has been manufactured using DELTASAFE, compared to the traditional MS 500 membranes.


In terms of appearance, Delta MS 500 Fire Retardant has the same physical properties to MS 500, a membrane designed from High-Density Polyethylene with 8mm stud.

 

Flood Testing/Integrity Testing 

 

The integrity of the waterproofing system should be checked and inspected on installation and immediately upon completion. If there is a delay before final handover or the laying of permanent coverings, a second test is strongly recommended. Test objectives should be decided upon prior to the method of testing.


Responsible manufacturing


Responsible manufacturing goes beyond traditional notions of green or sustainability.


As a responsible business, Delta provides waterproofing solutions that focus beyond environmental sustainability, we apply our principles to high-quality solutions. With targeted quality and safety measures at all levels - every day.

Achieving sustainability in manufacturing requires a comprehensive view spanning not just the product and the manufacturing processes, but also the entire supply chain, including product lifespan.


Delta provides life-cycle oriented designs, addressing life-cycle concepts and methods, deterioration and damage evaluation, life-cycle performance indicators, inspection and maintenance procedures all implemented to work in harmony.


BS 8201:2022


BS8102:2022 categorises structural waterproofing into three Types, these are: A, B & C.


Type A


Type A is defined as ‘barrier protection’. A material is used to offer a barrier to the passage of water. The barrier protection physically repressing water ingress on either the positive side of a below ground level structure (externally), the negative sides (internally) or sandwiched into the construction. Cementitious coatings, bituminous coatings, flexible sheet membranes, fully bonded membranes are all categorised within Type A ‘barrier protection’.


Type B


Type B is defined as ‘structurally integral protection’. Type B protection relies on the structure itself being constructed with concrete containing a water-resistant admixture. Structures providing Type B protection should be constructed from reinforced concrete or structured steel and designed in accordance with BS EN 1992 and BS EN 1993 respectively. 


Type C


Type C is defined as “drained protection”. BS 8102:2022 defines Type C, as a waterproof protection system that manages water that penetrates the external shell of a structure, by collecting this water in a cavity formed between the external wall and an internal lining/wall. There is a reliance of the Type C system to discharging any water which has percolated the structure via gravity drainage or a mechanical drainage system.


Grades of Waterproofing


Grades of waterproofing refer to water-tightness of the Type of waterproofing and desired robustness of the design at completion.
