Advanced admixture for integrally waterproof concrete structures to BS 8102:2009 Type B basement construction
ADPRUFE® 100 is an innovative liquid admixture that significantly reduces both the permeability and drying shrinkage of concrete. When used in combination with ADVA® superplasticisers, this enhanced concrete performance is achieved by:
- Reduced water absorption and penetration
- A significant reduction in drying shrinkage which produces fewer and thinner cracks
- A low water/cement ratio, which reduces capillary paths in the cured concrete
- High consistence concrete mix for ease of placement
- Enhanced compressive and tensile strengths at all ages.
When ADPRUFE® 100 is used with ADVA® high performance concrete admixtures, highly effective integrally waterproof concrete is achieved. ADPRUFE® 100 complies with EN 934-2.
- Design Flexibility - can be combined with GCP membranes or cavity drain systems for enhanced protection in critical applications providing compliance with NHBC Chapter 5.4 combined system requirements from a single source
- Reduces drying shrinkage and permeability of concrete
- Improved consistence resulting in easier, more complete compaction when containing ADVA® superplasticiser
- Can be used in all types of concrete, with all types of cementitious binders
- Concentrated, liquid formulation - considerably less than other liquid systems and more easily dispersed than a powder
- No expansive agents
- Improves early strength
- Can be combined with GCP membranes or cavity drain systems for enhanced protection in critical applications
- ADPRUFE® 100 - liquid waterproof concrete admixture
- ADVA® - high range water reducing/superplasticizing admixture.
- ADCOR® 500S - hydro expansive waterstop system for construction joints & penetrations
- SERVISEAL® AT - PVC/hydrophilic co-extruded waterstop for designed movement joints
- BETEC® 350 - cementitious compound for sealing tie-bar holes.
- ADPRUFE® 100 provides structurally integral waterproofing (Type B construction) as defined in BS 8102:2009 and is suitable for Basement grades 1 to 3
- Water retaining structures
- Swimming pools
- Lift pits
Concrete structures must be designed in accordance with BS EN 1992-1-1, BS EN 1992-1-2, BS EN 1992-3 and BS 8102, or a comparable code. Concrete containing ADPRUFE® should be designed in accordance with the requirements of BS EN 1992-1-1 having a maximum crack width of 0.3 mm; water retaining structures should be designed in accordance with BS EN 1992-3 having a maximum crack width of 0.2 mm, when the hydrostatic pressure/ wall thickness is ≤ 5. Additional design guidance for dwellings is given in The Building Regulation Approved Document, Basements for Dwellings.
Note: ADPRUFE® 100 is not recommended for elevated concrete decks. ADPRUFE® 100 is not intended or recommended for use in areas where concrete is expected to be exposed to repetitive freeze/thaw cycling, unless the concrete has been air-entrained Consult GCP for further advice.

Note: Optimal ADVA® addition rate should be determined by trial mix to ensure specified consistence and maximum water/cement ratio is achieved. Trial
mixes should always use specific cements and aggregates that will be used in the concrete. For further advice, consult GCP
All declared values shown in this data sheet are based on test results determined under laboratory conditions and with the product sample taken directly from stock in its original packing without any alteration or modification of its component parts.
Compatibility with Cements
ADPRUFE® 100 can be used with all general purpose cements and combinations including type II additions. For use with special cements we recommend that you consult GCP.
Compatibility with Other Admixtures
As with all concrete admixtures, ADPRUFE® 100 should not be pre-mixed with other admixtures or chemicals. The product is engineered to be used with GCP ADVA® superplasticisers, but must be dosed separately. Physical properties of the concrete may be adversely effected if Adprufe is used with other admixtures and chemicals.
Delivery and Storage
ADPRUFE® 100 is supplied in 15 and 205 litre non-returnable containers or in 1000 litre transitanks. Store under cover and protect from frost. If the product freezes, contact GCP for advice. Shelf life is 12 months in original, unopened containers. For other system components, refer to separate product data sheets.
ADPRUFE® 100 is engineered for use in concrete with medium to high consistence with an effective water/ cement ratio of <0.45. GCP recommend the use of ADVA superplasticisers (see separate product data sheet).
Where alternative superplasticisers are used, ensure they produce the specified consistence and effective water/cement ratio, at the equivalent cement content. When non GCP superplasticiser is being considered we recommend trial mixes to ensure compatibility. For further advice consult GCP.
It is preferable that ADPRUFE® 100 should be introduced into the mixer by means of automatic dispensing equipment.
Place concrete in accordance with the recommendations of BS 8000 1990 Section 2.2. Fully compact all concrete using best practices. Do not place concrete when ambient temperatures are 5°C or less. Refer also to ADPRUFE® Technical Bulletins for guidance.
Concrete should be cured in accordance with the recommendations given in BS EN 13670.
